2004 Buick Regal Water Pump Parts and Q&A

• Q: How to replace a water pump on 2004 Buick Regal?

  A: Draining the cooling system and relocating the accessory wiring junction block is the first step to replace the Water Pump. Start working by first detaching the Water Pump Pulley bolts, then the Drive Belt, uninstalling both the Water Pump bolts and pulley from the engine. Move the Power Steering Pump aside while taking out its retention bolts. Then unfasten the Water Pump bolts followed by the Water Pump itself. Pick out the Water Pump Gasket and examine and prepare the parts where it meets. Set the Water Pump on its gasket and bolt the long Water Pump bolts to 34 nm while tightening the short Water Pump bolts to 22 nm. Fasten the Water Pump Pulley with a torque of 13 nm. Restore the Power Steering Pump unit alongside Drive Belt and accessory wiring before filling the cooling system.
