GMC Yukon Water Pump Parts Questions & Experts Answers
A: 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.
