How to Ensure Proper Installation of a Water Pump on GMC Savana 2500?

The first step to replace a Water Pump is draining the cooling system while also removing air cleaner assembly components including Fan Clutch and accessory Drive Belt. Move the inlet hose clamp aside and detach the inlet hose before transferring the outlet hose clamp and taking out the outlet hose. You should now relocate the heater inlet hose clamp to disconnect the hose. Take out the Water Pump while removing its bolts and discard the original gaskets. Put new gaskets on the Water Pump before installation and make sure all sealing surfaces stay dry. Put on the Water Pump with new gaskets first, screw in all Water Pump bolts, but leave them at 15 nm (11 ft. Lbs.) before torquing them to their final value of 30 nm (22 ft. Lbs.). Reposition the heater inlet hose with its clamp before connecting the outlet hose with its clamp and finally installing the inlet hose and its clamp. After these pieces you reattach the accessory Drive Belt, fan blade, clutch assembly, air cleaner assembly and complete filling the cooling system.
