aPosition the engine oil pressure sensor tool (Mot.
836-05) fitted with suitable end pieces using the
(Mot. 1495-01) or a 1/2" long socket (12.7 mm
square drive).
aEnd pieces:
-D4F and D7F engines:
•end piece C + F
-K9K engine:
•end piece E + C + F
aStart the vehicle.
aMonitor the engine oil pressure as the engine oil
temperature increases (approximately 80˚C or the
first time the engine cooling fan is triggered)
which must not be lower than the pressure at idle
speed.
aIf the oil pressure is lower at idle speed, check that:
-the oil filter is not clogged,
-there is no dirt or swarf in the engine oil,
-the oil pump is in good condition and being correct-
ly driven.
aCheck the oil pressure at 3000 rpm.
aCheck the values:
-D4F and D7F engines:
•Idling: 0.8 bar
•3000 rpm: < 3.5 bars
-K9K engine•idling: 1.2 bar
•3000 rpm: < 3.5 bars
aSwitch off the engine.
aRemove the (Mot. 836-05) with the end pieces.
aRefit the oil pressure sensor (see 10A, Engine and
cylinder block assembly, Oil pressure sensor:
Removal - Refitting, page 10A-45) .
aWipe any oil run-off with a cloth.
aWait at least 10 minutes.
aCheck the oil level using the dipstick.
aTop up the engine oil level if necessary.
aStart the vehicle and check that there are no oil
leaks at the oil pressure sensor.
