Refilling
caution
  • Do not put additive such as waterleak preventive, since it may cause cooling waterway clogging.
  • When refilling use MITSUBISHI MOTORS GENUINE SURPER LONG LIFE COOLANT PREMIUM or equivalent in its quality mixed with water (distilled or demineralized). Refer to Fluids and Lubricants.
 
 
1. Install reservoir tank if removed and radiator drain cock.
cautionBe sure to clean drain cock and install with new O-ring.
Radiator drain cock: Refer to Exploded View.
  • If water drain plugs on cylinder block are removed, close and tighten them. Refer to Setting.
2. Check that each hose clamp has been firmly tightened.
3. Fill radiator to specified level.
cautionNever adhere the engine coolant to electronic equipments (alternator etc.).
  • Pour coolant slowly of less than 3 (1-3/4 Imp qt) a minute to allow air in system to escape.
    Engine coolant capacity
    (With reservoir tank at “MAX” level)
    Refer to Periodical Maintenance Specification.
4. Refill reservoir tank to “MAX” level line with engine coolant.
: MAX
: MIN
Reservoir tank engine coolant capacity
(At “MAX” level)
Refer to Periodical Maintenance Specification.
5. Install reservoir tank cap.
6. Warm up engine until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3,000 rpm.
  • Check thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
cautionWatch 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.
    cautionNever adhere the engine coolant to electronic equipments (alternator etc.).
8. Refill reservoir tank to “MAX” level line with engine coolant.
9. Repeat steps 3 through 8 two or more times with radiator cap installed until engine coolant level no longer drops.
10. Check cooling system for leakage 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 3 through 8 until reservoir tank level no longer drops.
warningTo avoid the blow out when the coolant is hot,never fill the coolant more than MAX level.
