Re: Need instructions to replace water pump in 97...
NOTE THIS IS FOR A 2.0L
- When replacing a water pump, it is necessary to drain the cooling
system.
- Any components--belts, fan, fan shroud, shaft spacers, or viscous
drive clutch--should be removed to make the pump accessible. Some pumps
are attached to the cylinder block as shown below.

- Loosen and remove the bolts in a crisscross pattern from the center
outward.
- Insert a rag into the block opening and scrape off any remains of
the old gasket.
WARNING
When working on the coolant system (for example,
replacing the water pump or thermostat), a certain amount of coolant
will spill on the floor. The antifreeze in the coolant causes it to be
very slippery. Always immediately wipe up any coolant that spills to
reduce or eliminate the chance of injury.
- When replacing a water pump, always follow the procedures
recommended by the manufacturer.
- Most often a coating of good waterproof sealer should be applied to a
new gasket before it is placed into position on the water pump.
- Coat the other side of the gasket with sealer, and position the pump
against the engine block until it is properly seated.
- Install the mounting bolts and tighten them evenly in a staggered
sequence to the torque specifications with a torque wrench. Careless
tightening could cause the pump housing to crack. Check the pump to make
sure it rotates freely.
- The water pumps on many late-model OHC engines are driven by the
engine's timing belt. When replacing the water pump on these engines,
always replace the timing belt.
- Make sure all pulleys and gears are aligned according to
specifications when installing the belt.
