PERIODIC MAINTENANCE
3-31
6. Start the engine, warm it up for several min-
utes.
NOTICE
ECA13410
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.
7. Measure:
• Engine oil pressure
(at the following conditions)
8. Remove:
• Oil pressure gauge
• Adapter C
• Oil pressure switch joint bolt
• Oil pressure switch joint (with the O-ring)
9. Install:
• O-ring “1”
• Oil pressure switch joint (with the oil pressure
switch) “2”
• Oil pressure switch joint bolt “3”

CHECKING THE COOLANT LEVEL
1. Stand the vehicle on a level surface.
TIP
• Place the vehicle on a maintenance stand.
• Make sure the vehicle is upright.
2. Check:
• Coolant level
The coolant level should be between the
maximum level mark “a” and minimum level
mark “b”.
Below the minimum level mark
→
Add the
recommended coolant to the proper level.
NOTICE
ECA21281
• Adding water instead of coolant dilutes the
antifreeze concentration of the coolant. If
water is used instead of coolant; check,
and if necessary, correct the antifreeze
concentration of the coolant.
• Use only distilled water. However, if dis-
tilled water is not available, soft water may
be used.
3. Start the engine, warm it up for several min-
utes, and then turn it off.
4. Check:
• Coolant level
TIP
Before checking the coolant level, wait a few
minutes until it settles.
