INSPECTION
ENGINE OIL
1. Be sure the vehicle is on level ground.
2. Warm up the engine to normal operating temper-
ature and stop it.
3. Wait for five minutes.
4. Remove the oil level gauge and check the oil lev-
el and condition.
5. Add or replace oil if necessary.
Note
The distance between the L and F marks on
the level gauge represents 1.2 liters (1.26 US
qt, 1.05 Imp qt).
OIL PRESSURE
1. Disconnect the oil hose (vacuum pump—cylinder
block).
76G02B-007
2. Set the SST as shown.
3. Remove the vacuum pump drive belt to prevent
heat damage to bearing.
4. Warm up the engine to normal operating tem-
perature.
76G02B-008
5. Run the engine first at 1,000 rpm, then at 3,000
rpm and note the gauge reading.
Standard oil pressure kPa (kg/cm2, psi)

1,000 rpm 147-245 (1.5-2.5, 21-36)
3,000
rpm
343—441 (3.5-4.5, 50—64)

6. If the pressure is not as specified, check for the
cause, and repair if necessary.
