Use a plug or otherwise cover the hose and nipple part of
the radiator so that dust, dirt, foreign materials, etc. do not enter after the hose has been disconnected from the
radiator.
INSPECTION
MWQCAN
a Check for foreign material between radiator fins.
l Check the radiator fins for bent, or damage.
l Check the radiator for corrosion, damage, rust or scale.
aCheck the radiator hoses for cracks, damage or deteriora-
tion.
l Check the reserve tank for damage.
lCheck the automatic transaxle oil cooler hoses for cracking,
damage or deterioration.
RADIATOR FAN MOTOR INSPECTION
(1) Check to be sure that the radiator fan rotates when battery voltage is applied between terminals (as shown in the
figure).
(2) Check to see that abnormal noises are not produced,
while motor is turning.

then jack up the vehicle.
Caution
Jack up carefully,
so as not to apply a load to each part.
(2) Remove the engine mount bracket.
5. REMOVAL OF DRIVE BELT Before removing the V-ribbed belt, loosen the water pump
pulley installation bolt.
INSPECTION

Check following items and replace if faulty.
l Check belt surface for damage, peeling or cracks.
l Check belt surface for oil or grease.
l Check belt rubber for wear or brittleness.
l Check the pulleys for cracks or damage.
WATER PUMP
lCheck each part for cracks, damage or wear, and replace
the water pump assembly if necessary.
l Check the bearing for damage, abnormal noise and sluggish rotation, and replace the water pump assembly if
necessary.
lCheck the seal unit for leaks, and replace the water pump
assembly if necessary.
lCheck for water leakage. If water leaks from hole “A”, seal
unit is leaking. Replace as an assembly.

26. INSTALLATION OF O-RING Insert the O-ring to the water inlet pipe, and coat the outer
circumference of the O-ring with water. By coating with water, the insertion to the water pump will
become easier.
Caution
1.Care must be taken not to permit engine oil or other
greases to adhere to the O-ring.
2.When inserting the pipe, check to be sure that there is no sand, dirt, etc. on its inner surface.
