ENGINE COOLANT LEAK CHECK

Scheme 24

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 OPENING PRESSURE CHECK

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

Scheme 25

1. Use a cap adapter to attach the radiator 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.
