ENGINE COOLANT LEAK CHECK

WARNINGWhen pressure testing the cooling system, slowly release cooling system pressure to avoid getting burned by hot coolant.
CAUTIONBe 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.
  1. 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.
  2. 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.

  1. Use a cap adapter to attach the cap to the tester.
  2. 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)
  3. Replace the radiator cap if the reading does not remain at or above the limit.

Scheme 31: RADIATOR FAN MOTOR CHECK
  1. Remove the radiator fan motor connector.
  2. 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.
  3. If the radiator fan motor is defective, replace it.

<< A >> RADIATOR LOWER HOSE DISCONNECTION

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

<< A >> RADIATOR UPPER HOSE DISCONNECTION

After making mating marks on the radiator hose and hose clamp, disconnect the radiator hose.

>> C << RADIATOR UPPER HOSE CONNECTION

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

After making mating marks on the radiator hose and hose clamp, disconnect the radiator hose.

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

Water Pipe and Hose Check

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