Engine Cooling System Mitsubishi Outlander Sport I рестайлинг

GENERAL INFORMATION

The cooling system is designed to keep every part of the engine at appropriate temperature in whatever condition the engine may be operated. The cooling method is of the water-cooled, pressure forced circulation type in which the water pump pressurizes coolant and circulates it throughout the engine. If the coolant temperature exceeds the prescribed temperature, the thermostat opens to circulate the coolant through the radiator as well so that the heat absorbed by the coolant may be radiated into the air. The radiator is the corrugated fin, cross flow type. The water pump is of the centrifugal impeller type and is driven by the drive belt from the crankshaft.

SYMPTOM CHART

PROBLEM SYMPTOMS

Scheme 1

1. STEP 1. Check for coolant leaks. WARNING: When pressure testing the cooling system, slowly release cooling system pressure to avoid getting burned by hot coolant. CAUTION: Be sure to completely clean away any moisture from the places checked. When the tester is removed, be careful not to spill any coolant. When installing and removing the tester and when testing, be careful not to deform the filler neck of the radiator. Check that the coolant level is up to the filler neck. Install a radiator tester and apply 160 kPa (23 psi) pressure, and then check for leakage from the radiator hose or connections. Q: Is leakage present from the radiator hose or connections? YES: Repair or replace the appropriate part, then go to Step 2. NO: There is no action to be taken.
2. STEP 2. Retest the system. Q: It there still coolant leakage? YES: Return to Step 1 . NO: The procedure is complete.
