2002 Cadillac Escalade Water Pump Parts and Q&A

• Q: How to replace the water pump on 4.8L, 5.3L, and 6.0L engines on 2002 Cadillac Escalade?

  A: Before handling 4.8l, 5.3l, and 6.0l Water Pump replacements you must drain the cooling system. Open the air intake duct clamps at both the Throttle Body and the maf/iat sensor before unpacking the radiator inlet hose from the outlet duct and removing the air intake outlet duct. When necessary detach the engine sight shield. Unclipped the vent inlet Radiator Hose then put the Water Pump hose clamp at the new position and extracted the hose. Quit the Fan Blade and disconnect the accessory Drive Belt. Take off the outlet hose through its clamp and afterward the surge tank outlet hose along its clamp and heater inlet hose with its clamp. Lift out the Water Pump by removing its bolts before replacing all gaskets with new ones. You must install new gaskets on the clean surfaces before fitting the Water Pump. Use 15 nm torque before tightening Water Pump bolts to 30 nm. Put back the heater inlet hose and its clamp onto the surge tank outlet hose and its clamp together with the outlet hose and its clamp. Put on the accessory Drive Belt and install the Fan Blade along with its inlet hose that has its installed clamp. You can reconnect the engine vent inlet hose to its place on the Radiator Hose fasteners before reinstalling the engine sight shield if needed. Position the arrow mark of the outlet air duct over the Throttle Body fastener before screwing it into place. Join the radiator inlet hose clip to the outlet duct last and use 62 inch lbs torque when tightening the clamps around the throat body and the maf sensor system.
