• Q: How to replace the cooling fan and fan shroud on 2002 GMC Envoy?

  A: The procedure of replacing the cooling fan and shroud begins by taking out the hood latch support and disconnecting transmission cooler lines at the engine until the Fan Shroud is free. Drain the cooling system after you remove the two upper bolts from the Fan Shroud. Apply hose clamp pliers tool j 38185 to position the upper inlet Radiator Hose clamp before removing the hose from the Radiator. Break the connection between the electrical shroud power then position the Water Pump with its bolts orienting vertically. Use a counterclockwise rotation to remove the Water Pump shaft fan hub nut while the fan clutch remover and installer (J 46406) keeps the Water Pump Pulley stable before unscrewing the cooling fan hub nut. The Fan Shroud requires unclipping from the Radiator side panel before tilting the Radiator forward and raising the fan and shroud towards the engine inlet opening. Secure the fan and shroud onto the Radiator bottom lip before tightening two bolts at the upper Fan Shroud to 28 nm (21 ft. Lbs.). Secure the Water Pump Pulley using the fan clutch remover (J 46406) while installing the fan nut at the Water Pump shaft in a clockwise direction until reaching 56 nm (41 ft. Lbs.) torque. Complete the installation by attaching the transmission cooler lines to the engine followed by installation of Fan Shroud before putting the hood latch support back in place in combination with attaching and clamping the upper inlet Radiator Hose using hose clamp pliers (J 38185) before filling the cooling system.
