Cooling system refresh

DIFFICULTY 2 / 5TIME VariesCOST Parts plus labor

Symptoms

Creeping temperature gauge, coolant weeps, or simply unknown history on an aluminium V8 that hates overheating.

The fix, step by step

  1. Replace the radiator, viscous fan coupling, water pump, thermostat and hoses as a set, then refill with a 50/50 coolant mix and bleed the air out.
  2. The aluminium block and heads depend on the cooling system.
