ON-VEHICLE SERVICE
ENGINE COOLANT LEAK CHECKING
1. Confirm that the coolant level is up to the filler neck. Install
a radiator cap tester, adapter and cap adapter to the filler
neck, 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 radiator filler
neck.
2. If there is leakage, repair or replace the appropriate part.
RADIATOR CAP VALVE OPENING PRESSURE
CHECK
1. Use a cap adapter to attach the cap to the radiator cap
tester.
2. Increase the pressure until the indicator of the gauge stops
moving.
Standard value: 75 ± 105 kPa
Limit: 65 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.
