How to replace the water pump on 4.8L, 5.3L, and 6.0L engines on GMC Sierra 1500?

You first need to drain the cooling system before starting work on 4.8l, 5.3l, and 6.0l engine Water Pump replacements. You can remove the air cleaner outlet duct by loosening the clamps around Throttle Body and maf/iat sensor. Take out the outlet duct through the hose connector. You can take down the engine sight shield and radiator vent hose from their clips on the radiator hose if necessary. First move the inlet hose clamp at the Water Pump before taking out the inlet hose then Fan Blade and accessory Drive Belt. Unclip the outlet hose barrel then take off the outlet hose plus surge tank outlet hose and heater inlet hose from the Water Pump. You need to remove Water Pump bolts and put out all components including gaskets while discarding old gaskets. Before putting in the Water Pump you should clean any oil residue from its gasket surfaces. Put new gaskets on the Water Pump and place the correct fasteners properly while keeping all fasteners free of paint or lubricant. Start by tightening the Water Pump bolts to 15 nm (11 ft lbs.) then continue to 30 nm (22 ft lbs.). Put back the heater inlet hose and its clamp then attach both surge tank outlet and outlet hoses with their seals. Install the accessory Drive Belt and Fan Blade. Place the inlet hose and its clamp at the engine vent inlet hose before connecting it to the radiator hose holders. Reinstall the engine sight shield by aligning the arrow on the Throttle Body end of the duct with the Throttle Body stud before connecting the air cleaner outlet duct. After mounting the hose clips secure the radiator inlet hose to its exit duct and tighten the air cleaner outlet clamps at Throttle Body and maf/iat sensor with 4 nm (35 inch lbs.) torque.

How to replace the water pump on GMC Yukon?

Start replacement of the Water Pump by removing the air cleaner outlet duct followed by draining the cooling system. Loosen and move the hose clamp away from the bleeding tube on the radiator coolant vent to remove the radiator vent inlet hose. Secondly you should relocate the radiator inlet clamp on top of the Water Pump and detach the radiator inlet hose. Reposition the radiator hoses aside to reveal the Water Pump. Displace the accessory Drive Belt after taking out both inlet lines. Detach the outlet hose from the Water Pump by unscrewing the radiator outlet clamp and replace it once done. Shift the clamp of the outlet hose towards the Water Pump and take off both the surge tank outlet hose and radiator. Put the outlet hose aside. Ease the heater inlet hose clamp from its position next to the Water Pump and extract the heater inlet hose. Detach all Water Pump bolts (301) and take out Water Pump (300) with gaskets (309) for disposal. Test the radiator vent passage before installing the pump to confirm proper airflow and clear the routing as needed. Place the Water Pump (300) into position with fresh gaskets (306) at the engine block, then put in the Water Pump bolts (301). Torque the bolts initially to 15 nm (11 lb ft) and end at 30 nm (22 lb ft). Secure the hose that leads to the heater door and its clamp before connecting the hose from the surge tank to its clamp on the radiator. Put the radiator outlet hose in place at the Water Pump area before installing its clamp. Connect the accessory Drive Belt afterward. Attach the radiator inlet hose in its correct position and then install the Water Pump hose above it along with securing the hose clamp at the Water Pump. Connect the radiator vent inlet hose to its proper place on the coolant air bleed pipe. Secure the hose with a clamp. Complete the cooling system before reconnecting the air cleaner outlet duct.
