• Q: How to replace the water pump on 2006 Chevrolet HHR?

  A: Before starting the Water Pump replacement process collect the Water Pump holding tool (J 43651) as well as other essential tools. First take off the Thermostat Housing then remove the Water Pump access plate from the front cover and the right-hand fender liner. Release the Water Pump coolant through its Drain Plug at the pump bottom base. Install the Water Pump holding tool j 43651 onto the Water Pump sprocket for safe working conditions while replacing the pump parts. Secure the tool to the front cover assembly by reinstalling the access cover bolts. Loosen the three bolts between the Water Pump sprocket and pump before disengaging the front and rear engine block bolts. Extract the Water Pump from the system in the end. Throw away the damaged Water Pump o-ring seal. Set a fresh Water Pump o-ring seal first before creating the guide pin from an m6 m x 6 mm stud to assist positioning with the Water Pump holding tool. Press the new Water Pump against the engine block and partially tighten its bolts by hand. Put in two inner Water Pump sprocket bolts partially and take out the guide pin before adding the last bolt. Use a torque wrench to first set all Water Pump bolts at 25 nm and then add a final 10 nm tension to the Water Pump sprocket bolts. Put back the Water Pump holding tool j 43651 and reset the Water Pump access plate before fixing the right-hand fender and Thermostat Housing in place.
