NOTICE
When the engine is cold, the engine oil will
have a higher viscosity, causing the engine
oil pressure to increase. Therefore, be sure
to measure the engine oil pressure after
warming up the engine.
3. Remove:
• Oil pressure switch joint bolt "1"
• Oil pressure switch joint (with the oil pressure
switch) "2"
