  Q: How to replace the water pump on Chevrolet Avalanche 1500?

  A:

  Before beginning repair you must drain the cooling system of its fluid. Detach the air cleaner outlet duct clamps at both Throttle Body and maf sensor positions. Then take off the radiator inlet hose clip that secures the outlet duct and the air cleaner outlet duct. Detach either the sight shield or radiator vent hose from their nipples on the radiator clip. Unclip the inlet hose from its position at the Water Pump before you remove both the inlet hose and the Fan Blade with accessory Drive Belt. Before continuing position the surge tank outlet hose clamp then take off the surge tank outlet hose. Take out the heater inlet hose at this point as well and afterward extract the Water Pump bolts while disposing of the used gaskets. Before putting on the Water Pump place new gaskets and make sure gasket surfaces remain clean during installation. Start by screwing in the Water Pump bolts fourteen point two five and ten point two five newton meters then turn them to thirty newton meters. Install heater inlet and surge tank outlet hoses first with their secured clamps then connect outlet hose with its clamps and set the accessory Drive Belt and Fan Blade. Place the inlet hose back on the engine while securing its clamp. Connect the engine vent inlet hose to Radiator Hose clips and put on the engine sight shield if needed. Attach the air cleaner outlet duct over the Throttle Body by aligning the arrow panel with its attaching stud and connect the radiator inlet hose cut to the outlet duct. While tightening both clamps ensure the sensor and Throttle Body reach 7 n.m (62 lb in). Add coolant to finish the work.
