Engine Oil: Testing and Inspection
OIL PRESSURE CHECK1. Check engine oil quality.
Check the oil for deterioration, entry of water, discoloring or thinning.
If the oil quality is visibly poor, replace it.
Oil grade:
API grade SH, Energy-Conserving II or ILSAC multigrade engine oil. Recommended viscosity is as shown in the illustration.
2. Check engine oil level.
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 "F" mark.
3. Remove oil pressure switch and install oil pressure gauge.
4. Warm up engine.
Allow the engine to warm up to normal operating temperature.
5. Check oil pressure.
Oil pressure:
At idle speed: 29 kPa (4.3 psi) or more.
At 3,000 rpm: 245 - 490 kPa (36 - 71 psi)
6. Remove oil pressure gauge and reinstall oil pressure switch.
(a) Remove the oil pressure gauge.
(b) Apply adhesive to 2 or 3 threads of the oil pressure switch.
Adhesive: Part No. 08833 - 00080, THREE BOND 1344, LOCTITE 242 or equivalent.
(c) Reinstall the oil pressure switch.
7. Start engine and check for leaks.
