Pontiac G5 Water Pump Parts Questions & Answers

  • Q: How do I remove the water pump on Pontiac G5?
    A: To remove the water pump, start by disconnecting the cable from the negative battery terminal. Then, remove the air intake duct and air filter housing. Loosen the lug nuts on the right front wheel, raise the vehicle, and support it securely on jackstands. Remove the wheel and drain the cooling system. If the vehicle has an automatic transaxle, remove the exhaust manifold. Remove the plug from the bottom of the water pump housing to drain the coolant. Next, remove the thermostat housing and its transfer pipe, along with the hoses connected to them. If equipped, remove the coolant heater and its mounting bolt. Depending on the model and engine, you may need to remove the exhaust heat shield, PCV system vent tube and hose, or catalytic converter. Disconnect any electrical connectors or harnesses that interfere with access. Unbolt the bracket for the underhood fuse/relay box if necessary. Remove the three bolts securing the thermostat housing to the engine, then separate the housing and transfer pipe from the water pump. Remove the right inner fender splash shield and unbolt the cover over the water pump sprocket from the engine front cover. Install a special holding tool onto the water pump sprocket to prevent movement. Remove the remaining water pump sprocket bolts and the bolts attaching the water pump to the engine block. Gently tap the water pump with a soft-faced hammer if it is stuck. Clean the bolt threads, threaded holes, and sealing surfaces, removing any corrosion or old gasket material. Finally, remove the sealing ring from the water pump.
