- If it is out of range, add oil as necessary. Refer to Procedures.

ENGINE OIL APPEARANCE

Check for oil leakage around the following areas:
- Oil pan
- Oil pan drain plug

- Oil filter
- Oil cooler
- IVTC cover
- Front cover
- Mating surface between cylinder block and cylinder head
- Mating surface between cylinder head and rocker cover

4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load, using Tool. Refer to Specifications.

NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
If difference is extreme, check oil passage and oil pump for oil leaks.
6. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and oil cooler.
b. Apply liquid gasket and tighten oil pressure switch to the specification.
