ENGINE COOLANT LEAK CHECKING
1. Confirm that the coolant level is up to the filler neck.
Install a radiator cap tester and apply 160 kPa pressure,
and then check for leakage from the radiator hose or
connections.
Caution
(1) Be sure to completely clean away any moisture
from the places checked.
(2) When the tester is taken out, be careful not to
spill any coolant from it.
(3) Be careful, when installing and removing the tester
and when testing, not to deform the filler neck
of the radiator.
2. If there is leakage, repair or replace the appropriate part.
RADIATOR CAP OPENING PRESSURE CHECK
14100130159
1. Use a cap adapter to attach the cap to the tester.
2. Increase the pressure until the indicator of the gauge
stops moving.
Limit: 64 kPa
Standard value: 74 - 103 kPa
3. Replace the radiator cap if the reading does not remain
at or above the limit.
NOTE
Be sure that the cap is clean before testing, since rust
or other foreign material on the cap seal will cause an
improper indication.
