5.
Check oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
If difference is extreme, check oil passage and oil pump for oil leakage.
6.
After the inspections, install oil pressure switch with the following procedure:
a.
Tighten oil pressure switch to specification.
b.
Check engine oil level.
c.
After warming up engine, check that there is no leakage of engine oil with running engine.
