WATER PUMP
The water pump body is made of aluminum with a
steel impeller. The water pump is bolted to the front
of the block, and driven by the timing belt. The water
pump is the heart of the cooling system, pumping the
coolant through the engine block, cylinder head,
heater core, and radiator.
NOTE: The water pump on all models can be
replaced without discharging the air conditioning
system.
WATER PUMP—2.5L ENGINE
The 2.5L pump bolts directly to the engine block,
using a gasket for pump to block sealing (Fig. 9). The
pump is serviced as a unit.
COOLANT INLET ELBOW THERMOSTAT WATER PUMP O-RING INLET PIPE
The water pump is driven by the timing belt. See
Timing System in Group 9, Engine for component
removal providing access to water pump.

WATER PUMP INLET TUBE— 2.0/2.4L ENGINES
The inlet tube connects the water pump to the
radiator and heater core. This tube is sealed by a
o-ring and held in place by fasteners to the block.
COOLANT
The cooling system is designed around the coolant.
The coolant must accept heat from engine metal, in
the cylinder head area near the exhaust valves. Then
carry this heat to the radiator where the tube/fin
assemblies of these components can give off the heat
to the air.
COOLANT REPLACEMENT
Refer to Group 0, Lubrication and Maintenance for
schedule.
