Cooling: Other Mitsubishi Galant IX facelift 2

ENGINE COOLANT LEAK CHECK

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 taken out, be careful not to spill any coolant. Be careful when installing and removing the tester and when testing not to deform the filler neck of the radiator.

Scheme 33

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.
If there is leakage, repair or replace the appropriate part.

RADIATOR CAP PRESSURE CHECK

Note. Be sure that the cap is clean before testing. Rust or other foreign material on the cap seal will cause an improper reading.

Scheme 34

Scheme 34: RADIATOR CAP PRESSURE CHECK

Use a cap adapter to attach the cap to the tester.
Increase the pressure until the indicator of the gauge stops moving. Minimum limit: 83 kPa (12 psi) Standard value: 93 - 123 kPa (14 - 18 psi)
Replace the radiator cap if the reading does not remain at or above the limit.

Scheme 37

Scheme 37: RADIATOR FAN MOTOR CHECK

Remove the radiator fan motor connector.
Check to see that the fan motor of the radiator turns when applying battery power between the connector terminals of the radiator fan motor. Also check to see that there is no abnormal sound coming from the radiator fan motor at this time.
If the radiator fan motor is defective, replace it.
