ENGINE COOLANT LEAK CHECK

M1141001000065

WARNING

When pressure testing the cooling system, slowly
release cooling system pressure to avoid getting
burned by hot coolant.

CAUTION

•

Be sure to completely clean away any moisture from
the places checked.

•

When the tester is taken out, be careful not to spill any
coolant from it.

•

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 cap 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

M1141001300066

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.
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: 64 kPa (9.2 psi)

Standard value: 73

−−−−

103 kPa (11

−−−−

15 psi)

3. Replace the radiator cap if the reading does not remain at or

above the limit.

1. Remove condenser fan motor connector.

2. Start the engine and run it at idle.

3. Turn the A/C switch to ON and maintain the coolant

temperature at 80

°

°

F) or less.

4. When measuring the voltage between the fan controller-side

connector terminals, check that the value changes
repeatedly as indicated by (1)

REMOVAL SERVICE POINTS

<<A>> RADIATOR UPPER HOSE/RADIATOR LOWER HOSE
DISCONNECTION
After making mating marks on the radiator hose and the hose
clamp, disconnect the radiator hose.

<<B>> A/T OIL COOLER HOSE REMOVAL
After removing the hose from the radiator, plug the hose and
the radiator nipple to prevent dust or foreign particles from
getting in.

INSTALLATION SERVICE POINT

>>A<< RADIATOR LOWER HOSE/RADIATOR UPPER HOSE
CONNECTION
1. Insert each hose as far as the projection of the water inlet

fitting.

2. Align the mating marks on the radiator hose and hose

clamp, and then connect the radiator hose.
