CLEANING AND INSPECTION
WATER PUMP
Replace water pump body assembly if it has any of
these defects:
(1) Cracks or damage on the body.
(2) Coolant leaks from the shaft seal, evident by
coolant traces on the pump body.
(3) Loose or rough turning bearing.
(4) Impeller rubs either the pump body or the
engine block.
(5) Impeller loose or damaged.
(6) Sprocket or sprocket flange loose or damaged.
ACCESSORY DRIVE BELT INSPECTION
Belt replacement under any or all of the following
conditions is required, excessive wear, frayed cords or
severe glazing.
Poly-V Belt system may develop minor cracks
across the ribbed side. These minor cracks are con-
sidered normal and acceptable. Cracks parallel are
not (Fig. 40).
NOTE: Do not use any type of belt dressing or
restorer on Poly-V Belts.
COOLING SYSTEM CAP
Hold the cap in your hand,right side up(Fig. 41).
The vent valve at the bottom of the cap should open
with a slight pull. If the rubber gasket has swollen,
preventing the valve from opening, replace the cap.
If any light can be seen between vent valve and
the rubber gasket, replace the cap.Use only a
replacement cap that has a spring to hold the
vent shut.
A replacement cap must be of the type designed for
coolant reserve systems. This design ensures system
pressurization.

Draining in this section for procedure.
(2) Refill with clean water. Refer to Cooling Sys-
tem Refilling in this section for procedure.

Draining in this section for procedure.
(2) Remove radiator hoses from engine.
(3) Install suitable flushing gun in radiator lower
hose.
(4) Fill radiator with clean water and turn on air
in short blasts.
CAUTION: Internal radiator pressure must not
exceed 138 kPa (20 psi) as damage to radiator may
result. Continue this procedure until water runs
clear.
ENGINE FLUSHING
(1) Drain radiator. Refer to Cooling System Drain-
ing in this section for procedure.
(2) Remove hoses from radiator.
