2007 Cadillac Escalade ESV Water Pump Parts and Q&A

• Q: How to replace the water pump (300) on RPOs LY6/L76/L92 on 2007 Cadillac Escalade ESV?

  A: Change the rpo ly6/l76/l92 engine Water Pump 300 by first taking off the air cleaner outlet duct and draining the cooling system. Turn loose the radiator vent inlet clamp at the coolant air bleed pipe fitting before you pull out the radiator vent inlet hose. Press the hose clamp holder on top of the Water Pump before detaching the inlet Radiator Hose. To start the job move the radiator hoses aside from the way and take out the accessory Drive Belt. Unclamp and take the radiator outlet hose off at the Water Pump before repositioning the tube. Attach the hose clamp on the surge tank outlet at the Water Pump location before taking out this Radiator Hose. Position the outlet hose as you remove it. Unclamp the inlet hose from the Water Pump at the heater and carefully disconnect it before putting the hose aside. Take out the Water Pump bolts (301) and the Water Pump (300) unit along with the gaskets (309) and dispose of the gaskets. Install the Water Pump by making sure no oil or foreign substances touch the gasket areas. Set the Water Pump (300) onto the engine block using new gaskets (306) and fasten Water Pump bolts (301) first to 15 n.m (11 lb ft) then to 30 n.m (22 lb ft). Place the Water Pump hose back into position at the Water Pump with the clamp. Then connect the radiator surge tank outlet hose and clamp. Set the radiator outlet hose into its position at the Water Pump and put on its clamp before placing the accessory Drive Belt. Spread the radiator hoses right using the Water Pump connections and clamp and mount the radiator inlet tube to the pump. Your last step includes installing the radiator vent inlet hose onto the air bleed pipe fitting and holding it in place with the clamp before filling the cooling system and installing the air cleaner outlet duct.
