Things You'll Need:
- Coolant
- Screwdriver
- Metric sockets to fit bolts (each car is different, you will have to measure)
- Socket ratchet
- Water pump
- Sealer that resists coolant
- O-ring
- Catch pan
- Rag
-
Step 1
Collect all the materials and tools necessary for this project. Consult the list of things you will need to make sure you have everything. Replacing the water pump is a big project, so it is important to have all of the necessary tools. Place a large sheet of cardboard under your car to catch drips.
-
Step 2
Detach the battery so that the car is no longer operational. Remove the air filter from the vehicle. Loosen hose clamps and unclip the tabs holding the filter in place. Drain all of the coolant out of the radiator. Use the catch pan for this.
-
Step 3
Find the water pump. It should be attached to the radiator at some point. Find the bolts holding the pump into place, and remove them with the ratchet. Wipe away the grease and sealant with the rag. Remove the old pump. Find the old o-ring connecting the old pump to the pipe leading to the radiator. Remove it and throw it away. Replace it with the new o-ring.

Step 4
Spread some sealant on the surface where the old pump was attached to the engine. Place the new water pump into the old water pump's place. Make sure to line everything up so that it is easy to bolt the pump into place.
-
Step 5
Bolt the new water pump into place. Make sure to tighten very tightly. However, it is also important to not over-tighten. 105 pounds of torque per inch is a good amount to tighten. Attach the different pipes and accessories where they belong the way the old pump was attached. Make sure the drain pipe reaches the radiator.
-
Step 6
Fill the radiator back up with coolant. Re-attach the battery. Turn the car on to make sure everything is working properly. Make sure nothing is leaking under the car, and that the temperature of the car is where it is supposed to be.
