Engine Cooling - Except Evolution: Other Mitsubishi Lancer IX

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 121

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 122

Scheme 122: 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.

<< A >> RADIATOR UPPER HOSE/RADIATOR LOWER HOSE DISCONNECTION

Make mating marks on the radiator hose and the hose clamp. Disconnect the radiator hose.

Scheme 123

Scheme 123: << A >> RADIATOR UPPER HOSE/RADIATOR LOWER HOSE DISCONNECTION

<< B >> TRANSAXLE OIL COOLER HOSE CONNECTION

After disconnecting the hose, plug it to avoid entry of dust or foreign material.

Scheme 124

Scheme 124: >> A << RADIATOR LOWER HOSE/RADIATOR UPPER HOSE CONNECTION

Insert each hose as far as the projection of the water inlet fitting.
Align the mating marks on the radiator hose and hose clamp, and then connect the radiator hose.

Radiator Fan Motor Check

Check to be sure that the radiator fan motor operates when battery voltage is applied to terminals 1 and 2.

Scheme 126: REMOVAL AND INSTALLATION

<< A >> RADIATOR LOWER HOSE DISCONNECTION

Make mating marks on the radiator hose and the hose clamp. Disconnect the radiator hose.

Water Pipe and Hose Check

Check the water pipe and hose for cracks, damage and clogs. Replace them if necessary.
