2000-2005 3.1L, 3.4L & 3.8L water pump DIY

3.1L, 3.4L & 3.8L Impala Engines

1.Place a drain pan underneath the radiator. When the engine is cool, drain the cooling system from the radiator into the pan.

2.Disconnect the negative battery cable.

3.Remove the accessory drive belt guard and the accessory drive belt. On 2001 and later 3.8 models, remove the power steering pump.

4.Loosen the water pump pulley bolts and remove the water pump pulley along with the water pump from the engine. Use a prybar or a long screwdriver to keep the pump pully from turning while loosening the bolts. Most, if not all new water pumps will have a locating mark at the top of the pump.After removing the old water pump clean the gasket mating surfaces by using a gasket scraper. Then clean the surface with acetone, I use fingernail polish remover with acetone in it.

5.Install the new water pump along with a new gasket, tightening the bolts to 89 inch pounds for 3.1 & 3.4 engines. For 2000 and 2001 3.8 engines, tighten the short bolts to 132 inch pounds then tighten an additional 80 degrees. For the long bolts tighten to 15 foot pounds then tighten an additional 40 degrees. For 2002 and later 3.8 engines tighten the short bolts to 16 foot pounds and the long bolts to 25 foot pounds.

6.Reinstall the water pump pulley, tightening the bolts to 18 foot pounds for 3.1 and 3.4 engines. For the 3.8 tighten the bolts to 115 inch pounds.

7.Insert the accessory drive belt back into the engine along with the drive belt guard, and the power steering pump if you are working on a 3.8

8.Reattach the negative battery cable and refill the cooling system. Start the car, bleed the air from the system and check for leaks when the engine reaches normal operating temperature.
