Engine Lubrication System: Diagnosis Honda Pilot I

Oil Pressure Test

If the low oil pressure indicator stays on with the engine running, check the engine oil level. If the oil level is correct

Scheme 4

1. Connect a tachometer.
2. Remove the engine oil pressure switch, and install an oil pressure gauge (A).
3. Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing.
4. Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be: Engine Oil Temperature: 176°F (80°C) Engine Oil Pressure At Idle: 70 kPa (0.7 kgf/cm 2 , 10 psi) minimum At 3,000 rpm: 490 kPa (5.0 kgf/cm 2 , 71 psi) minimum
5. If the oil pressure is not within specifications, inspect these items. Check the oil screen for clogging. Inspect the oil pump (see «Inspection»(ref-173991-S35900846212005041500000) ).

Scheme 5

1. Warm up the engine.
2. Remove the drain bolt (A), and drain the engine oil.
3. Reinstall the drain bolt with a new washer (B).
4. Refill with the recommended oil .
5. Capacity At Oil Change: 4.4 l (4.6 US qt) At Oil Change Including Filter: 4.8 l (5.1 US qt) After Engine Overhaul: 5.4 l (5.7 US qt)
6. Run the engine for more than 3 minutes, then check for oil leakage.
