2. REMOVAL OF ENGINE MOUNT BRACKET
(1) Place a wooden block at the oil pan part of the engine, and
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
V-RIBBED BELT
M14MDAG
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.
SERVICE POINTS OF INSTALLATION
Ml4MEAm
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.

(1) Immerse the air conditioning engine coolant temperature switch in oil and then heat (by using a gas stove flame or
similar method) so as to increase the oil temperature.
(2) Check to be sure that the air conditioning engine coolant temperature switch is switched OFF when the oil tempera-ture reaches the standard value.
Standard value:
