ENGINE MAINTENANCE (VQ35DE ENGINE)
When engine coolant overflows air relief hole on heater hose,install air relief plug with new O-ring.
5. Install radiator cap.
6. Warm up until opening thermostat. Standard for warming- up time is approximately 10 minutes at 3,000
rpm.
Make sure thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
7. Stop the engine and cool down to less than approximately 50 °C (122 °F).
Cool down using fan to reduce the time.
If necessary, refill radiator up to filler neck with engine coolant.
8. Refill reservoir tank to “MAX” level line with engine coolant.
9. Repeat steps 4 through 7 two or more times with radiator cap installed until engine coolant level no longer drops.
10. Check cooling system for leaks with engine running.
11. Warm up the engine, and check for sound of engine coolant flow while running engine from idle up to 3,000 rpm with heater temperature controller set at several position between “COOL” and “WARM”.
Sound may be noticeable at heater unit.
12. Repeat step 11 three times.
13. If sound is heard, bleed air from cooling system by repeating step 4 through 7 until engine coolant level no
longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank, and radiator drain plug.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-123, "
Dis-
assembly and Assembly".
2. Remove air relief plug on heater hose.
3. Fill radiator with water until water spills from the ai r relief hole, then close air relief plug. Fill radiator and
reservoir tank with water and reinstall radiator cap. Reservoir tank engine coolant capacity
