aStart the vehicle.
aMonitor the engine oil pressure as the oil tempera-
ture rises (approximately 80˚C or the first time the
engine cooling fan is activated); it should not be less
than the pressure at idle speed.
aIf the oil pressure is lower than the pressure at idle
speed, check that:
-the oil filter is not clogged,
-dirt or swarf is not present in the engine oil,
-the oil pump is in good condition and being correct-
ly driven. Special tooling required
