ON-VEHICLE SERVICE
ENGINE COOLANT LEAK CHECK
1. Confirm that the coolant level is. up to the filter
Install a radiator cap tester and apply 160 (23 psi)
pressure, and then check for leakage from
radiator
hose or connections.
Caution
1. After testing, clean up all coolant seepagefrom
areas of leakage.
2.When the tester is removed, be careful not to spill
any coolant.
3.During tester usage, do not deform the filler neck
of the radiator.
2. If leakage is present, repair or replace the app ropriate
part.
RADIATOR CAP VALVE OPENING
CHECK
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..
Standard value:

3.Replace the radiator cap if the reading does not re main
at or above the limit.
NOTE
Be sure that the radiator cap is clean before testing,
since rust or other foreign material on the radiato r cap
seal may cause an improper reading.

INSPECTION
RADIATOR FAN MOTOR CHECK
(1)Check to be sure that the radiator fan rotates when battery,
voltage is applied between terminals (as shown the
figure).
(2) Check to see that abnormal noises are not
while motor is turning.
