The engine in a 1993 Chevrolet Silverado has a water pump mounted on the front of the engine. This pump is used as a coolant delivery system for the motor, as it circulates the coolant through the block and to the radiator. When the water pump fails, the engine risks overheating. If you notice your Silverado overheating, replace the water pump to ensure everything is working correctly.
Tools Used: Tools, Drain pan, Flat-head screwdriver, 3/8-inch ratchet, extension and socket set, 3/8-inch breaker bar, Gasket scraper, Replacement water pump, Replacement water pump gasket, 3/8-inch torque wrench, 50-50 pre-diluted coolant
Replace a Water Pump
Allow the Silverado to cool for several hours. Open the hood, and remove the radiator cap. Crawl under the front of the truck, and put the drain pan under the drain at the bottom of the radiator. Open the drain, and empty the radiator.
Locate the belt tensioner at the top corner of the engine. Turn the tensioner counter-clockwise with the 3/8-inch breaker bar and a socket, then pull the belt off the water pump.
