Symptoms
Due on age or mileage, no paperwork, or a weeping water pump. PistonHeads also notes the oil-pump casing that the timing-belt tensioner bolts to can snap off.
The fix, step by step
- PistonHeads advises replacing the belt, tensioner, small pulleys and water pump within six years or 60,000 miles.
- Lock the engine with the correct timing tools before removing the old belt, fit the full kit and pump, and turn the engine by hand before starting.
- Note there are separate Euro 3 and Euro 4 belt kits for the 2.7, so match the kit to your engine.
Tools & part numbers
- TDV6 timing tool set, torque wrench, coolant
- Euro 4 kit LR019115 or Euro 3 kit 1324390
