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.

2. Screw the SST into the pressure switch installa-
tion hole.
3. Warm up the engine to normal operating tem-
perature.
4. Run the engine at 3,000 rpm, and note the gauge
reading.
Oil pressure:
343—441 kPa
(3.5—4.5 kg/cm2, 50—64 psi)...DOHC 2g4 392 kPa
(3.0—4.0 kg/cm2, 43—57 psi)...SOHC
5. If the pressure is not as specified, check for the
cause, and repair if necessary.
(Refer to Troubleshooting Guide.)
ENGINE OIL
REPLACEMENT
1. Warm up the engine to the normal operating tem-
perature and stop it.
