The water pump on your 1993 Chevrolet S-10 circulates the coolant from the radiator throughout the engine, cooling it down in the process. When the water pump goes out, the coolant can’t circulate in the engine and the engine can overheat. An overheating engine can be very expensive to repair and it can cause a lot of damage. To fix the problem, the water pump will have to be removed from the engine; and that should take about an hour to do.
Tools Used: Tools, Drain pan, Flat-head screwdriver, Open-end wrench set, 3/8-inch ratchet and socket set, Gasket scraper, RTV Sealant, Replacement water pump, 50-50 pre-diluted coolant
Change Out a Water Pump
Allow the engine to cool for several hours to allow the coolant to cool down. Put the drain pan below the radiator. Open the petcock on the bottom of the radiator and drain the coolant into the drain pan.
Loosen the alternator belt mounting bolts and the power steering pump mounting bolts, using the 3/8-inch ratchet and socket and an open-end wrench.
