Nissan Patrol Y60 (GQ)

Y60 / GQTD42 4.2 DIESEL I6COIL-SPRUNG LIVE AXLES

“The coil-sprung Patrol that beat Toyota to the punch by three years and never stopped reminding Land Cruiser owners about it. It's slow, thirsty and always on the lookout for rust, and in TD42 form it's close to unkillable.”

PART 01

Overview

Where it came from, why it matters, and how it changed year to year.

The story

The Y60 Patrol, sold in Australia as the GQ, is the truck that made Toyota nervous. When it arrived in the late 1980s it was the first Patrol with coil springs at both ends: a three-link live axle up front, a five-link live axle out back, power steering as standard, and a separate ladder frame underneath. The 60 Series Land Cruiser it fought in showrooms was still on leaf springs. Nissan kept that advantage until Toyota launched the 80 Series in 1990, and Australians have been arguing about which one is tougher ever since.

COILS, SIXES AND A TWO-SPEED BOX

Production started in Japan in 1987, where the truck was also sold as the Nissan Safari, and Nissan's Barcelona plant in Spain built it from 1988. Underneath, it was refreshingly old-school. Every engine was a straight six: the 4.2-litre TB42 petrol (125 kW and 325 Nm on a carburettor), the 4.2-litre TD42 diesel (85 kW, 264 Nm), and the 3.0-litre RB30 petrol borrowed from Nissan's passenger cars. A 2.8-litre RD28T turbo-diesel joined later. Drive went through a five-speed manual or four-speed automatic to a two-speed transfer case with part-time 4WD.

The wagons came in short- and long-wheelbase form (2,400 and 2,970 mm), plus a high-roof version, and there were utes and cab-chassis models too. Those workhorses kept a leaf-spring rear axle until 1994, when Nissan offered the wagons' coil rear as an option. Most Y60s left the factory with a rear limited-slip differential. Some got a vacuum or electric rear diff lock, a rear sway-bar disconnect, or even a front winch driven from a power take-off, with its lever beside the gearstick.

THE TD42, AND EVERYTHING ELSE

The engine that built the legend is the TD42. It's a cast-iron, overhead-valve, indirect-injection diesel whose camshaft is driven by gears rather than a belt or chain, which CarsGuide calls a 'set-and-forget system'. It's slow and thirsty, at roughly 12 to 14 L/100 km on the highway, but it is reputed to reach half a million kilometres if serviced. Early engines wear a silver rocker cover. From August 1993 Nissan lightened the TD42 to save fuel and let it rev harder, and Wikipedia notes this weakened it. Those engines, and later ones, wear black covers.

The petrol engines are the other side of the coin. 4X4 Australia's own 1988 TB42 project car, an automatic, hit boiling point on its first High Country climb and boiled over three more times before the top, and its writer admits 'the TB42 loves a drink'. CarsGuide warns that petrol heads can crack, especially on LPG after the coolant has run low, and Wikipedia lists head-gasket trouble on hard-driven TB42s and RD28Ts. The 1992 Series 2 update brought fuel injection for the TB42, bigger brakes and wheels, and standard limited-slip diffs and automatic free-wheeling hubs. A 1994 facelift added a new grille.

WHAT MADE IT SPECIAL

In the bush, the GQ simply worked. Coil springs gave it axle articulation and a ride the leaf-sprung competition couldn't match, and its axles earned a reputation for strength. That made the GQ the default heavy tourer and club truck across Australia, Africa and the Middle East. Even Ford wanted one. Under Australia's Button car plan Ford sold the Y60 as the Ford Maverick from the late 1980s to 1994, changing little but the badges. And Team Nissan France Dessoude was still racing Y60-based Patrol GRs in the Dakar Rally's T1 class in 1998.

The Patrol also has a tighter connection to America than its absence suggests. Datsun dealers sold the 60 Series here from 1962 to 1969, but the Y60 was never offered in the US. Every Y60 is now more than 25 years old, which puts it inside the federal 25-year exemption from US safety-standard compliance. Bring a Trailer lists a steady flow of imported right-hand-drive Safaris and Patrols, many of them TD42 or RD28T manuals from Japan and Europe.

HOW IT ENDED, AND WHY IT STILL MATTERS

The Y61, or GU, took over in late 1997. 4X4 Australia describes it as essentially a GQ platform underneath, with a wider body, a better interior and about 230 kg more weight. That continuity is why GQ owners still share parts, forums and bolt-on hardware with GU owners. Much of the GU's running gear, from the swivel hubs and radius-arm bushes to ARB Air Lockers and steering dampers, is sold as fitting both trucks.

Today the GQ occupies the same place in Australian off-roading that the 60 and 80 Series do in American trail culture. It's cheap enough to modify without guilt, simple enough to fix with hand tools, and big enough to carry a family and a fridge to the end of the track. It isn't fast, the petrol engines drink like it's still 1988, and rust is never far away. But with a TD42 and a set of 33s, few trucks this old are still this capable.

SIDEBAR · THE BADGE SWAP

The Ford Maverick: a Patrol in a blue oval

In the late 1980s Australia's Button car plan pushed local makers to share models so the industry could consolidate. One result was the Ford Maverick, a Y60 Patrol sold through Ford dealers from 1988 (some sources say 1989) to 1994. Curbside Classic notes the visual changes were limited to badging. Unlike many Button-plan twins, neither truck was built in Australia.

The Maverick came as two- and four-door wagons, a ute and a cab-chassis, in base, XL and XLT trims, with the 4.2-litre petrol and diesel sixes. There was no luxury model to rival the Patrol Ti. Rural Ford dealers and their fleet deals helped it sell. For buyers today, a Maverick is simply a GQ: parts suppliers such as Patrolapart and HD Automotive list the Ford alongside the Nissan.

Year by year

What changed, model year by model year. Sweet spot Beware

  1. 1987Y60 launches in Japan as the Safari (October/November). It's the first Patrol on coil springs: three-link live front axle, five-link rear on wagons. TD42 diesel and TB42 petrol 4.2 L sixes
  2. 1988Australian (GQ) launch. Spanish production begins in Barcelona for Europe, where it's sold as the Patrol GR. Ford sells a rebadged version in Australia as the Maverick until 1994. Four-speed automatic added
  3. 1991Japan gets the 7-seat Safari and the TB42E. Wikipedia's Patrol article says the turbo TD42T replaced the TD42 in Japan this year (its engine article says 1993). In Australia the rear lamps move into the bumper to meet ADRs, but not on European trucks
  4. 1992Australian GQ Series 2: fuel injection for the TB42, oil cooler and EGR for the RD28T (in markets that had it), bigger brakes and wheels, standard limited-slip diff and auto-free-wheeling hubs, side-intrusion barsSweet spot
  5. 1993From August, the TD42 is lightened to save fuel and rev higher, which weakens it. Early 'Silvertop' engines are the ones to want; later ones have a black rocker cover. Wikipedia's engine article dates the colour change to around 1995Beware
  6. 1994Minor facelift with a new grille. Coil-sprung rear axle becomes an option on the utility, which previously had leaf springs
  7. 19954X4 Australia dates the 2.8 L RD28T's Australian arrival to 1995 (CarsGuide says 1992); Wikipedia lists the RX grade from 1994–95. In Japan, Autech launches the Safari Adieu, a high-roof hearse conversion
  8. 1996–1997Europe gets the LW, a lightweight-body version built for off-road championships. Wagons give way to the Y61 from late 1997; Australian UY60 cab-chassis sales run to 1999

Specs & capability

How it’s built, what it can do, and what fits under it.

How it’s built

The GQ is a body-on-frame truck with solid axles at both ends. Coil springs replaced the old Patrol's leaves, with radius arms and a panhard rod at the front and a five-link rear. A two-speed transfer case and free-wheeling front hubs give part-time 4WD. The engines are big, slow-revving straight sixes, and the TD42 diesel's camshaft is gear-driven. Most of what goes wrong is heat, rust, and front swivels that have been neglected.

Expect some rubbing at full flex; some owners add radius-arm spacers.

Forum consensus, not a guarantee: wheel offset, tire brand and suspension wear all change clearance. Confirm before you buy.

Buying one

What to pay, what to check, and how to tell a good one from a clone.

What they cost

Every US Y60 is a 25-year gray import, and prices are still far below an 80 Series Land Cruiser's. Clean, unmodified diesel wagons with paperwork bring the most, and so do well-built modified trucks.

Project / needs work$5k–9k
Driver$12k–20k
Excellent / well modified$21k–31k (modified builds to about $42k)

Based on 17 Y60 Bring a Trailer sales from May 2022 to October 2026. Prices ran from a $5,000 1988 Safari Granroad turbo-diesel to a $41,500 modified 1993 TD42 turbo wagon. A 1996 Patrol GR SLX turbo-diesel sold for $23,000, and swap trucks (a Barra six and a 6.0 L V8) went for $21k–22k. Fire-truck Safaris sell for $8.5k–26.5k. Prices move; checked October 2026. See live listings below.

What to check before you buy

  1. 01
    Rust first, everything else secondForum veterans check the roof gutters, the sliding rear-window frames, the door sills and jambs, the front guards, the backs of the rear wheel arches and the upper firewall. Lift the rear carpets too, because sand under the mats can eat the floor pans. A freshly painted GQ can be hiding gutter and rear-quarter rust.
  2. 02
    Look for oil on the swivel hubsGreasy gunk on the front swivels usually means the inner axle seal has failed and diff oil is getting past swivel seals that were never designed to hold oil. That's a front-axle teardown, so price it in. Look for oil on the brake backing plates as well, a sign of worn axle seals. CarsGuide adds that leaks from the rear diff seals are common on GQs, though regular servicing usually cures them.
  3. 03
    Drive it at 70–80 km/h (45–50 mph)Early GQs suffered a front-end shimmy at about 70–80 km/h. Most were fixed under warranty by removing knuckle shims to take out free play, but a worn truck can bring it back. Owners also report shakes around 110 km/h, so test at highway speed and check the tie rods, panhard rod and radius-arm bushes.
  4. 04
    Know which engine, and which rocker coverThe TD42 is the safe bet if it has been kept cool. A silver rocker cover means a pre-August-1993 engine, from before Nissan lightened it. Petrol TB42s and turbo RD28Ts have a history of head problems when worked hard. Ask about the cooling system, look for milky oil and coolant stains, and walk away from a truck that 'just needs a head gasket'.
  5. 05
    Open and close every doorIf a door drops when you open it, the hinge pins are worn, a well-known GQ problem. Wikipedia also records cracking rear-door hinges from the weight of the spare. Both are fixable with hinge-pin kits or new genuine hinges, but they tell you how hard the truck has been used.
  6. 06
    Test 4WD in high and low rangeCheck that the free-wheeling hubs lock and unlock smoothly, then drive in 4H and 4L on dirt. One forum tip is a tight circle in low range, which should scrub the tyres. Listen for gearbox whine or clunks, check that it doesn't jump out of gear on overrun, and inspect the gearbox crossmember for rock damage. Wikipedia also records fifth-gear bearing failures in high-mileage European five-speeds.
  7. 07
    Be wary of automaticsMembers of the NissanPatrol.com.au forum report trouble with GQ automatics, with rebuilds around A$3,000. The auto's cooler also sits inside the radiator, so a truck that overheats can cook its transmission too. A manual with a service history is the conservative choice.
  8. 08
    If it's lifted, check the detailsOn lifted GQs, confirm that the brake lines were extended, the rear load-proportioning valve was adjusted, and caster was corrected with offset radius-arm bushes. Bent rear lower control arms and stone-damaged rods suggest it has been driven hard.

Spotting the real thing

Nissan never sold a Y60 new in the US, so every American truck is a gray import from Japan, Australia, Europe or the Gulf. The badge, the steering side and the engine all depend on where the truck came from.

  1. ID
    Four names, one truckY60 is Nissan's series code. Australians call it the GQ, Europe calls it the Patrol GR, and Japan sold it as the Safari. Ford Australia sold a rebadged version as the Maverick from 1988 to 1994.
  2. ID
    Japanese chassis codesCodes seen on Japanese catalogues and preserved trucks include VRY60 (short hardtop, 2,400 mm wheelbase), VRGY60 (long 'Extra Van' and Granroad, 2,970 mm), WGY60 (Kingsroad extra-high-roof wagon), WYY60 (RD28T short hardtop, e.g. Spirit Type II) and UY60 (Australian cab-chassis).
  3. ID
    Which TD42Early naturally aspirated TD42s have a silver rocker cover ('Silvertop'). Turbo engines and later lightened engines are black ('Blacktop'). Owners prefer the early engine, so check before you pay Silvertop money.
  4. ID
    Lockers and winchMost Y60s have a rear limited-slip diff. Some have a vacuum- or electric-solenoid rear diff lock, and some have a PTO-driven front winch with a control lever to the right of the gear stick. Look for the switch and the lever rather than trusting the ad.
  5. ID
    24-volt SafarisJapanese Safaris were available with a 24 V electrical system instead of 12 V. That matters for every bulb, starter and accessory you buy, so check which one you have.
  6. ID
    Market tellsSpanish-built European trucks are left-hand drive and kept their rear lamps in the body. Australian trucks moved them into the bumper from 1991, and from 1994 they gained extra indicators on the front quarter panels.

Recalls & service bulletins

Service bulletins & known fixes
Front-end vibration ↗Wikipedia lists front-end vibration as a known Y60 weakness that was 'largely fixed under warranty'. Ask whether a truck had the fix, especially if it shimmies.

Importing & legality

Nissan never sold the Patrol new in the United States; the closest relatives sold there are the much later Y62-based Infiniti QX56/QX80 and Armada. Every US Y60 is a gray import: right-hand-drive Japanese Safaris, Australian GQs, left-hand-drive Spanish-built European Patrol GRs and Gulf trucks.

Since 1989, NHTSA has exempted vehicles at least 25 years old (counted from the vehicle's own manufacture date) from its safety standards, so every Y60 now qualifies. The EPA has a separate exemption (Form 3520-1, code E) for vehicles at least 21 years old in original, unmodified configuration. Replacement engines don't qualify unless they're the same engine model as originally fitted, or an engine and aftertreatment from a certified vehicle no older than the one being imported. That matters for the TD42-swapped GR, Barra-swapped and V8-swapped Patrols that turn up at auction.

California's emissions rules make registering an overseas classic difficult there even when the federal rules are met, and other states vary. Canada uses a 15-year rule, so some Patrols reach the US by way of Canada. Check your state's titling, inspection and emissions rules before you buy.

Rules change and vary by state and country. Confirm with your DMV and a licensed importer before you buy.

After you buy it

Assume nothing has been done unless there are receipts. On a GQ, the jobs that matter most are the cooling system, TD42 tappets, a timing belt on RD28T and RB30 engines, gear oils (with LSD oil in the rear), and the front swivels, which run in grease and quietly fill with diff oil when the inner seals fail. Capacities below are owner-reported figures from forum threads (grades quoted from Gregory's), so confirm them in a workshop manual for your engine.

Common repairs

The jobs owners actually end up doing, rated for a competent home mechanic with a decent tool kit. Always confirm torque figures, fluids and procedures against the factory service manual for your VIN, and work safely — support the truck on stands, never just a jack. You do this work at your own risk; see the disclaimer. Some parts links are affiliate links.

Swivel hub (kingpin) bearing and seal rebuild
DIFFICULTY · 3 / 5TIME · ≈ A full day per side for a first-timerSHOP COST · Parts plus labor
SYMPTOMSGreasy gunk on the front swivel balls, steering that wanders, or play when you rock the top of the tyre with the wheel off the ground. On a GQ the swivel and CV bearings run in grease. If diff oil is leaking out of the swivels, the inner axle seal has failed.
THE FIXJack up and support the front, then remove the wheel, free-wheeling hub, CV circlip, brake caliper (hang it up, don't let it dangle), wheel bearings and hub. Unbolt the swivel housing from the axle, pull the CV and axle shaft, and replace the inner axle seal while it's out. Replace the upper and lower kingpin bearings and the swivel cap seals (owners often damage the caps on removal), then reassemble. Set kingpin preload with the factory shims and fit new wiper seals on the swivel ball. Repack with fresh grease and, if any diff oil was lost, top up the front diff.

SYMPTOMSRumble or growl that changes with speed, play at the wheel, or bearing grease slung onto the brake parts. It's also due whenever you rebuild the swivels.
THE FIXFollowing a NissanPatrol.com.au how-to: support the front on stands and remove the wheel. Take off the free-wheeling hub, the CV circlip, the hub internals and the 'egg ring'. Unbolt the caliper and rest it on the swivel. Flatten the locking plate, undo the outer 54 mm bearing nut, remove the plate and the second 54 mm nut, then slide the hub and rotor off. Punch out the pressed-in races, remove the rear seal and bearings, then fit the new races, bearings and seal. Adjust bearing preload to the manual before locking the nuts. Don't rest the axle on the new seal during reassembly.

Then check the panhard-rod bushes and the radius-arm bushes for splits and movement while a helper rocks the steering. CarsGuide says the factory fix on early trucks was to remove shims from the top and bottom of the steering knuckles to take out free play, so check kingpin preload. Replace anything worn, have the front end aligned, and fit a fresh steering damper last, since a damper hides worn parts rather than fixing them.
TOOLS & PARTSPry bar · ball-joint/tie-rod separator · torque wrench · a helper on the steering wheel. Alignment afterward.
TD42 tappet adjustment and rocker cover reseal
DIFFICULTY · 2 / 5TIME · ≈ 1–2 hoursSHOP COST · Parts plus labor
SYMPTOMSA louder-than-usual top-end clatter, or an oily rocker cover. One forum member says the TD42's tappets want adjusting about every 20,000 km, and that poor early servicing leads to serious valve-train wear.
THE FIXWith the engine cold, remove the rocker cover. Turn the crank to TDC on cylinder 1 and adjust valves 1, 2, 4, 5, 8 and 9. Rotate to TDC on cylinder 6 and adjust 3, 6, 7, 10, 11 and 12. One forum member sets 0.35 mm at ambient temperature; confirm the intake and exhaust figures in the workshop manual. Fit a new rocker-cover gasket and breather seals, then refit the cover evenly.
TOOLS & PARTSFeeler gauges · ring spanner and screwdriver for the adjusters · large socket to turn the crank · new gasket kit.
Cooling system refresh (overheating prevention)
DIFFICULTY · 2 / 5TIME · ≈ Half a daySHOP COST · Parts plus labor
SYMPTOMSThe temperature gauge climbs on long climbs or when towing, the truck boils at low speed, or the clutch fan roars without cooling much. GQs have a reputation for heat, and an overheated head is the expensive end of that story. On automatics, the transmission cooler is inside the radiator.
THE FIXPressure-test the system and check the radiator for blocked cores. Replace the top and bottom hoses and the thermostat (TD42 trucks use a 76°C genuine unit). Inspect the water pump for weeping and the fan clutch for slip, and bleed the system properly. CarsGuide says most TD42 overheating is on modified trucks: aftermarket turbos add heat, front-mounted intercoolers and driving lights block airflow, and big tyres make the engine work harder. If the head has already been cooked, have it pressure-tested and checked for warp at a machine shop before refitting.
TOOLS & PARTSCooling-system pressure tester · drain pan · hose pliers · new clamps · coolant (type per manual).
Re-pin dropping front doors
DIFFICULTY · 2 / 5TIME · ≈ 1–2 hours per doorSHOP COST · Parts plus labor
SYMPTOMSThe door drops when opened and has to be lifted to latch. Forum members call door hinges a common GQ problem; worn pins can be in either or both hinges.
THE FIXSupport the door on a jack with a block of wood, or with a helper. Drive out the old hinge pin, then press out the worn bushes and fit new pins and bushes, one hinge at a time so the door stays aligned. If the hinge itself is worn or cracked, fit a genuine replacement hinge set and adjust the door gaps before tightening.
TOOLS & PARTSPunch and hammer · vise or press · floor jack and wood block · grease.
RD28T timing belt service
DIFFICULTY · 3 / 5TIME · ≈ A day for a first-timerSHOP COST · Parts plus labor
SYMPTOMSNo warning before it breaks. Unlike the gear-driven TD42 and TB42, the RD28T's camshaft is belt-driven, so a truck with no receipts should be treated as due. Owners on ExplorOz report doing it at about 100,000 km; confirm the interval in the manual.
THE FIXUse a kit that includes the tensioner and idler, because one owner found both noisy and loose once the old belt was off. Remove the fan, belts and harmonic balancer; soaking the crank bolt overnight helped one first-timer. Line up the timing marks, then fit the belt, tensioner, idler, and the crank and cam seals while you're in there. Forum members suggest replacing the balancer bolt in case it's torque-to-yield, and checking the Woodruff key. Wikipedia's RD-engine article warns that diesel vibration can loosen the crank/balancer bolt and recommends thread-locker on reassembly.
TOOLS & PARTSHarmonic balancer puller · crank-holding tool · breaker bar · torque wrench · seal puller.
Replace radius-arm and panhard bushes (with caster correction)
DIFFICULTY · 3 / 5TIME · ≈ Half a day to a daySHOP COST · Parts plus labor
SYMPTOMSClunks over bumps, vague steering, the shimmy above, or a lifted truck that wanders because the lift has reduced caster. One owner expects to replace the bushes, springs and clutch at around 200,000 km.
THE FIXSupport the chassis with the axle on a jack, then unbolt one radius arm at a time so the axle stays located. Press out the old bushes and press in new ones. On lifted trucks, fit offset caster-correction bushes at the diff end to restore caster. Do the panhard-rod bushes at the same time, torque everything at ride height, and get an alignment.
TOOLS & PARTSHydraulic press or bush tool · floor jack and stands · long breaker bar · torque wrench.

Nissan Patrol Y60 (GQ) questions, answered

What's the biggest tire I can fit without a lift?

4X4 Australia says its 1988 GQ wore 31-inch all-terrains from the factory, and 31x10.50R15 or a similarly sized 16-inch tyre is the safe size on standard suspension. A 33 does fit 'into the GQ wheel arch, but only just', according to the Patrol 4x4 Club SA forum. On NissanPatrol.com.au, owners say 33x12.5s on zero-offset rims scrub the inner guards at full flex. The common recipe is a 2-inch lift with 33x12.5R15s on negative-offset wheels (owners quote -22 to -24 mm), which push the tyres out past the factory flares. Even then, expect some rub at full lock or full flex, often on the front mud-flap bracket.

Which engine should I buy?

The TD42 diesel, if you can find a good one. It has a gear-driven cam, it's simple, and it's reputed to last half a million kilometres when serviced and kept cool. Early 'Silvertop' engines predate the August 1993 lightening that Wikipedia says weakened it. The TB42 petrol makes more power but is thirsty, and petrol heads crack, especially on LPG. The RD28T needs timing belts and dislikes being thrashed, and the RB30 is the economy option.

SOURCE · WIKIPEDIA · CARSGUIDE
What's a 'Silvertop' versus a 'Blacktop' TD42?

It's the colour of the rocker cover. Early naturally aspirated TD42s have silver covers. Wikipedia's Patrol article says Nissan lightened the engine in August 1993 to cut fuel use and raise its rev limit, which weakened it, and that the lightened engine wears a black cover. Its TD-engine article says turbo TD42s and non-turbo engines built after 1995 are black. CarsGuide adds that the later pistons were less tolerant of aftermarket turbo kits, and that owners cracked pistons by running too much boost.

SOURCE · WIKIPEDIA · CARSGUIDE
Does it have lockers?

Most Y60s have a rear limited-slip differential, and LSDs became standard with the 1992 Series 2 in Australia. Some variants had a factory vacuum or electric rear diff lock. For selectable lockers, ARB makes front and rear Air Lockers for the GQ. The rear version depends on your diff: H233 on most trucks, or H260 (34- or 37-spline) on leaf-sprung cab-chassis models.

SOURCE · WIKIPEDIA · PATROLAPART
Can I legally bring one into the US?

The Y60 was never sold new in the US. Datsun dealers sold the older 60 Series only from 1962 to 1969. Every Y60 is now more than 25 years old, which puts it inside NHTSA's exemption from federal safety-standard compliance for vehicles at least 25 years old. Check EPA and state titling rules too. Bring a Trailer's Patrol page shows a steady stream of imported Y60 Safaris and Patrols, most of them right-hand-drive manuals.

What fuel economy should I expect?

Not much. CarsGuide puts a TD42 at roughly 12–14 L/100 km on the highway (about 17–20 mpg), plus a couple of litres around town and much more when towing. The petrol sixes are thirstier still: 4X4 Australia's carbureted TB42 project truck needed extra fuel on the roof rack because 'the TB42 loves a drink'. All wagons have a 100-litre main tank, and long-range replacements are available.

SOURCE · CARSGUIDE · 4X4 AUSTRALIA · WIKIPEDIA
Why do GQs overheat, and how do I stop it?

CarsGuide says most TD42 overheating happens on modified trucks: aftermarket turbos add heat, intercoolers and driving lights in front of the radiator block airflow, and big tyres make the engine work harder. 4X4 Australia's TB42 project truck boiled on a long climb until it got a genuine radiator and a better fan. Keep the radiator clean, use the correct thermostat (76°C on the TD42), replace hoses and fan clutches, and watch the gauge.

What oils and capacities does it take?

One owner on NissanPatrol.com.au quotes the Gregory's manual for his 1990 GQ DX 4.2 manual: 20W-40 engine oil, 75W-90 GL-4 in the manual gearbox and transfer case, and 80W-90 GL-5 in both diffs. His own fills were about 8.2 L of engine oil, 3.9 L in the gearbox, 2.2 L in the transfer case, 5.4 L in the front diff and 3.0 L of 85W-140 in the rear. Owners with LSDs use LSD-rated oil (85W-140 LS is common). A TD42 takes two oil filters. These are owner figures, not factory data, so confirm them in your workshop manual for your engine.

Is a Ford Maverick the same truck?

Yes. Under Australia's Button car plan, Ford sold the Y60 as the Ford Maverick from the late 1980s to 1994, and Curbside Classic says the visual changes were limited to badging. It came as wagons, a ute and a cab-chassis in base, XL and XLT trims with the 4.2-litre sixes. Patrol parts suppliers list GQ parts as fitting the Maverick.

SOURCE · CURBSIDE CLASSIC · WIKIPEDIA
GQ or GU: which should I buy?

4X4 Australia describes the GU as essentially a GQ platform underneath, with a wider body, better refinement and about 230 kg more weight. It also brings the later TD42T and TB48 engines, but also the troubled ZD30 four-cylinder diesel. The GQ is lighter, simpler and usually cheaper, and much of the suspension and axle hardware is shared. See the Y61 GU page for the other side of the argument.

SOURCE · 4X4 AUSTRALIA
Automatic or manual?

Manual, if you can. CarsGuide says every TD42 sold in Australia was a manual, and the RD28T and RB30 were manual-only. NissanPatrol.com.au members report problems with GQ automatics and rebuilds of around A$3,000. The auto's transmission cooler sits inside the radiator, so cooling problems become transmission problems.

PART 05

Building one

Who makes the good stuff, where owners gather, and who to watch.

Common modifications & who does them

SUSPENSION LIFTA 2-inch coil lift is the standard GQ upgrade, and it's what makes 33s livable. Pair it with caster-correction bushes, longer brake lines and a rear proportioning-valve adjustment.
LOCKERSA rear LSD is good; selectable lockers are better. ARB Air Lockers are the usual retrofit at both ends, so make sure you know whether your rear diff is an H233 or an H260.
SNORKEL & BREATHERSOn a stock GQ the rear diff breathes near the fuel tank, and the front diff, gearbox and transfer case share one breather in the passenger guard. Raise them all, and raise the engine's intake with a snorkel, before you start fording creeks.
BAR WORK & RECOVERYA winch-compatible bullbar is close to mandatory in Australia, and 4X4 Australia's project truck found the factory recovery points hard to trust in a bog hole.
FUEL RANGEA 100-litre tank and a thirsty six don't add up to remote-area range. Long-range main and auxiliary tanks are the classic GQ touring fix.
MANUAL HUBSAutomatic free-wheeling hubs on ST, Ti and Series 2 trucks are another thing to fail out bush. Many owners convert to manual hubs.
COOLING & TD42 POWERTurbocharging a TD42 is a well-worn path, but CarsGuide warns it adds heat. Budget for a better radiator before you add boost, and mount any intercooler with airflow in mind.
