If the low oil pressure indicator stays on with the engine running, check the engine oil level. If the oil level is correct:
1. Remove the oil pressure switch (A).
2. Install the oil pressure hose, the A/T pressure hose, the A/T low pressure gauge w/panel, the A/T pressure hose, 2,210 mm and the A/T pressure
hose adapter.
3. Install the oil pressure switch in the pressure gauge adapter (B).
4. Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing.
5. Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be:
6. If oil pressure is not within specifications, inspect these items:
-
Inspect the oil pressure relief valve. See: Oil Pump/Service and Repair
-
Check the oil screen for clogging.
-
Inspect the oil pump. See: Oil Pump/Service and Repair
