OIL PUMP
Tools Required
KM–498–B Pressure Gauge
KM–135 Adapter
Engine Oil Pressure Inspection Procedure
1. Remove the right front wheel, wheel well splash
shield and engine undercover.
2. Disconnect the oil pressure switch connector.
3. Install the adapter KM–135 in place of the oil pres-
sure switch.
4. Connect the pressure gauge KM–498–B to the
adapter.
5. Start the engine and check the oil pressure at idle
speed and engine temperature of 80°C (176°F).
The minimum oil pressure should be 30 kPa (4.35
psi).
6. Stop the engine and remove the pressure gauge
KM–498–B and the adapter KM–135.
7. Install the oil pressure switch.
Tighten
Tighten the oil pressure switch to 40 NSm (30 lb–ft).
8. Connect the oil pressure switch connector.
9. Install the right front wheel well splash shield, en-
gine undercover and wheel.
10. Check the oil level. Pour oil until it reaches the full
mark.
Removal Procedure
1. Disconnect the negative battery cable.
2. Remove the power steering pump, if equipped. Re-
fer to Section 6A, Power Steering System.
3. Remove the timing belt. Refer to”Timing Belt” in this
section.
4. Remove the rear timing belt cover. Refer to ”Rear
Timing Belt Cover” in this section.

7. Clean the oil pump housing and all the oil pump
parts.
8. Inspect all the oil pump parts for signs of wear. Re-
fer to ”Engine Specifications” in this section. Re-
place the worn oil pump parts.
Notice : Pack the oil pump gear cavity with petroleum jelly
to ensure an oil pump prime, or engine damage could re-
sult.
9. Coat all the oil pump parts with clean engine oil.
Install the oil pump parts.
10. Apply Loctite® 242 to the oil pump rear cover bolts
and install the cover and bolts.
Tighten
Tighten the oil pump rear cover bolts to 8 NSm (71 lb–
in).
11. Install the safety relief valve, spring, washer and
bolt.
Tighten
Tighten the safety relief valve bolt to 30 NSm (22 lb–ft).
Installation Procedure
