2001 Buick Regal Water Pump Parts and Q&A

• Q: How to replace the water pump on a 3.8L engine on 2001 Buick Regal?

  A: Before replacing the Water Pump for a 3.8l engine start by removing part of the cooling system fluid then moving the accessory wiring junction block. Install the hose clamp pliers (J 38185) to loosen Water Pump Pulley bolts before you detach the Drive Belt and bolts to take off the wheel shaft. First remove the Power Steering Pump mounting bolts before repositioning it. Then disconnect the Water Pump bolts and take off the Water Pump along with its gasket. Determine if the Water Pump mating surfaces need cleaning before inspecting the area. Start with both components on the Water Pump before you employ the torque angle meter (J 36660-A) to tighten bolt sets gradually. Work on long bolts first at 20 nm (15 ft. Lbs.) plus 40 degrees and short bolts afterwards at 15 nm (11 ft. Lbs.) plus 80 degrees. Attach the Water Pump Pulley loosely before adding its bolts and installing the Power Steering Pump with its bolts. Put the Drive Belt back in its place before securing the Water Pump Pulley bolts at 13 nm. Put back the accessory wiring junction block before filling the cooling system with fluid.
