1. CHECK ENGINE OIL QUALITY
a) Check the oil for deterioration, entry of water, discoloring or thinning. If the quality is visibly poor, change the oil.
Oil grade: API grade SM Energy-Conserving or ILSAC multigrade engine oil.
2. CHECK ENGINE OIL LEVEL
a) The oil level should be between the "L" and "F" marks on the dipstick.
If low, check for leakage and add oil up to the full level mark.
NOTICE: Do not fill with engine oil above the "F" mark.
HINT: SAE 5W-30 is the recommended choice for this engine for good fuel economy and good starting in cold weather.
3. REMOVE ENGINE UNDER COVER
4. REMOVE OIL PRESSURE SWITCH
5. INSTALL OIL PRESSURE GAUGE
6. WARM UP ENGINE
a) Allow the engine to warm up to normal operating temperature.
7. CHECK OIL PRESSURE
a) Measure the oil pressure.
8. REMOVE OIL PRESSURE GAUGE
9. REINSTALL OIL PRESSURE SWITCH
a) Apply adhesive to 2 or 3 threads of the oil pressure switch.
Adhesive: Part No. 08833-00080, THREE BOND 1344, LOCTITE 242 or equivalent.
b) Reinstall the oil pressure switch.
10. START ENGINE, AND CHECK FOR ENGINE OIL LEAKS
