4.
Install pressure gauge [SST] and hose [SST].
5.
Start the engine and warm it up to normal operating temperature.
6.
Check the engine oil pressure with engine running under no-load.
NOTE:
When the engine oil temperature is low, the engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80
°
C (176
°
F)]
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.
