qt) a minute to allow air in system to escape.
3. Warm up engine to normal operating temperature without radia-
tor cap installed.
lIf coolant overflows radiator filler hole, install filler cap.
4. Run engine at 3,000 rpm for 10 seconds and return to idle speed
with radiator cap installed.
lRepeat two or three times.
Watch coolant temperature gauge so as not to overheat the engine.
5. Stop engine and cool down to less than approximately 50°C(122°F).
lCool down using a fan to reduce the time.
lIf necessary, refill radiator up to filler neck with coolant.
6. Refill reservoir tank to MAX level line with coolant.
7. Repeat steps 5 through 7 two or more times with radiator cap installed until coolant level no longer drops.
8. Check cooling system for leaks with engine running.
9. Warm up engine, and check for sound of coolant flow while running engine from idle up to 3,000 rpm with
heater temperature controller set at several position between COOL and WARM.
lSound may be noticeable at heater unit.
10. If sound is heard, bleed air from cooling system by repeating steps 5 through 7 until coolant level no
longer drops.
lClean excess coolant from engine.
