2004 Chevrolet Silverado Water Pump: Replacement and Maintenance Guide

If you want to replace the water pump in your car, follow these step-by-step instructions to get the job done.

You’ll need a collection bucket to recycle the coolant and some basic tools like wrenches, a screwdriver, and pliers to help with the process.

First, locate the petcock at the bottom left-hand corner of the radiator and drain the coolant into the collection bucket. Then, remove the clamps and bolts to access the water pump.

Next, remove the fan clutch and serpentine belt before loosening the hose clamps and removing the hoses connected to the thermostat housing.

After removing the mounting bolts for the water pump, carefully detach the old pump, clean the surface where the gasket will sit, and install a new gasket.

Position the new water pump, torque the bolts to the manufacturer’s specifications, and reattach the hoses, thermostat, and tensioner.

Once everything is securely in place, reinstall the belts, fan clutch, and shroud. Fill the cooling system with the proper coolant and run the engine to check for leaks before taking your car for a road test.
