2. Install oil pressure gauge and hose.
3. Check engine oil level. Refer to LU-15, "
Inspection".
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80°C (176°F)]
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 engine.
b. Apply liquid gasket and tighten oil pressure switch to specification.
Use Genuine Silicone RTV Sealant or equivalent. Refer to GI-27, "
Recommended Chemical Prod-
ucts and Sealants".
c. Check engine oil level. Refer to LU-15, "
Inspection".
d. After warming up engine, make sure there are no engine leaks of oil with running engine.
ENGINE OIL : Changing Engine OilINFOID:0000000001730866
WARNING:
Be careful not to burn yourself, as engine oil may be hot.
Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct skin
contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand cleaner as
soon as possible.
1. Warm up engine, park vehicle on a level surface and check for engine oil leakage from engine compo-
nents. Refer to LU-15, "
Inspection".
2. Stop engine and wait for 10 minutes.

INSPECTION
WARNING:
Be sure to perform when the engine is stopped.
1. Inspect drive belt for cracks, fraying, wear and oil. Replace drive belt if necessary.
2. Manually evaluate the drive belt tension (tension cannot be measured using frequency meter).
3. Replace drive belt when tension is beyond normal operating limit.
CAUTION:
Auto-tensioner must be replaced with a new one when the belt is replaced.
ADJUSTMENT
Belt tensioning is not necessary, as it is automatically adjusted by auto-tensioner.

4. Start engine without closing reservoir tank cap and keep engine racing at 1,500 rpm for about 2-3 minutes.
If necessary, pour engine coolant up to MAX level.
If coolant overflows reservoir tank hole, install filler cap.
Watch engine coolant temperature gauge so as not overheat the engine.
WARNING:
Be careful not to be scaled with hot engine coolant or vacuum pump when operating.
Radiator fan blade can start at any time and cause personal injuries.
5. Turn off the engine and loosen air relief plug until coolant spills from air relief hole.
6. Close the air relief plug and run the engine at 2,000 rpm until the upper hose becomes hot and radiator
fan operates. Leave the engine running approximately 5 minutes at idle speed and check for sound of
coolant flow while running engine from idle up to 3,000 rpm.
Sound may be noticeable at heater water cock.
7. If sound is heard, bleed air from cooling system by repeating steps 4 to 6 until coolant level no longer
drops.
Check the radiator lower hose for any signs of leakage.
8. Turn off the engine and let it cool down.
Cool down using a fan to reduce the time.
9. After cooling period, loosen the air relief plug and check if coolant spills from the air relief hole. if not,
remove the air relief plug until the coolant spills, and then close the relief air plug. Bleed air from cooling
system by repeating steps 6 to 10 until the coolant spills immediately.
10. Check the engine coolant level when engine is cool and refill to MAX level line if the level is lower.
Clean excess coolant from engine.
11. Check that the reservoir tank cap is tightened.
ENGINE COOLANT : FlushingINFOID:0000000001730883
1. Install reservoir tank if removed.
If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-314, "
Exploded
View".
2. Fill reservoir tank with water until water spills from the air relief hole, then close air relief plug. Reinstall
reservoir tank cap.
3. Run engine and warm it up to normal operating temperature.
4. Rev engine two or three times under no-load.
5. Stop engine and wait until it cools down.
6. Drain water.
7. Repeat steps 1 through 6 until clear water begins to drain from radiator.
8. Blow compressed air into cooling circuit through the reservoir tank valve hole to drain all the water.
