Things You'll Need:
- Drain pan
- Wrench set
- Coolant
-
Step 1
Place a drain pan underneath the radiator. When the engine is cool, drain the cooling system from the radiator into the pan. Disconnect the negative battery cable.
-
Step 2
Take out the drive belt, the alternator and the timing belt cover.
-
Step 3
Disconnect the following hoses from the water pump: the engine hose, heater hose and the lower radiator hoses.
-
Step 4
Loosen and remove the water pump bolts, taking note of where you have removed them for installation, as they are various lengths.
-
Step 5
Remove the water pump, turning it just slightly to remove it from the engine block. Separate the water pump pulley from the pump.
-
Step 6
Clean all the mating surfaces and attach the pulley to the new pump.
-
Step 7
Put a good amount of silicone compound onto the seals of the pump and install new o-ring seals. Install the new pump into the engine with a new pump gasket, tightening the bolts to 7 foot pounds (10 Nm).
-
Step 8
Tighten the bolts to the pulley to 15 foot pounds (20 Nm) after the belt has been installed and tensioned.
-
Step 9
Reattach and reconnect all remaining parts in the order in which they were removed.
-
Step 10
Refill the cooling system and reconnect the negative battery cable. Start the engine and check for leaks when it reaches normal operating temperature.
