How to Replace a Water Pump on a Car: Preparation
Step 1: Disconnect the Battery
The first step in how to replace a water pump on a car is to disconnect the battery. This is a safety measure to prevent any electrical issues while working under the hood. Make sure the ignition is off and the keys are removed.
Step 2: Drain the Coolant
Next, you’ll need to drain the coolant from the radiator. Place a drain pan underneath the radiator and remove the radiator cap. This will allow the coolant to drain completely, making it safe to remove the water pump.
Step 3: Remove the Serpentine Belt
To access the water pump, you’ll need to remove the serpentine belt. Use a wrench to loosen the tensioner pulley, then slide the belt off the pulleys. Be sure to note how the belt is routed so you can reinstall it correctly later.

The water pump is typically located on the front or side of the engine, driven by the serpentine belt. Once you’ve removed the belt, you’ll have better access to the pump.
Step 5: Remove Bolts and Attachments
To remove the old water pump, use your wrenches and sockets to remove the bolts securing it in place. Carefully disconnect any hoses or attachments connected to the pump. As you remove the water pump, keep track of any gaskets or seals, as you will need to replace them with the new pump.
