How to Install the Water Pump on a 1999 Protege

A faulty water pump can cause overheating or coolant leaks and may lead to engine damage. The water pump in a 1999 Mazda Protege is driven by the timing belt, and is often replaced when the timing belt is replaced to prevent future problems. Most auto-parts shops will have replacement pumps in stock or will order one if needed.

Instructions

1

Drain the engine coolant into a container that holds at least 6.3 qts. by twisting the plastic drain plug on the rear of the radiator.

2

Unbolt the air cleaner assembly. The assembly is on the right side of the engine compartment, to the rear of the battery. A single bolt on the right side holds it in place.

3

Squeeze the tabs on the air intake hose clamp where the hose connects to the engine and pull the hose loose. Remove the air cleaner assembly and hose.

4

Remove the insulating shroud from the exhaust manifold on the front of the engine. It is held on by four bolts.

5

Remove the timing belt.

6

Unbolt the water pump from the right side of the engine block. Unbolt the flange connecting the water line to the pump. Remove the pump.

7

Replace the pump. Installation is the reverse of removal.
