How to replace the water pump (8.1L) on GMC Sierra 3500?

Before replacing the Water Pump you need to empty the cooling system fluids then take off the Drive Belt and Fan Clutch. Moving the outlet hose clamp allows simple detachment of the outlet hose from the Water Pump. Push back the clamps at both the Water Pump and the crossover water mandrel before removing the bypass hose. Secure the bolts of the Water Pump before removing it from the engine block. Drop the used gaskets when you discard the Water Pump. You must use new gaskets before setting the Water Pump in place and tightening its bolts to 50 nm (37 ft. Lbs.). Reinstall your bypass hose and place its clamps both at the Water Pump and water crossover components. Fix the outlet hose to the Water Pump and lock the hose with the outlet clamp. Put back the Fan Clutch then slide on the Drive Belt before refilling the cooling system.
