• Q: How to replace the Electric Cooling Fan Motor on 2004 Chevrolet Classic?

  A: The necessary tools for electric cooling Fan Motor replacement include hose clamp pliers (J 38185) and halogen leak detector (J 39400-A). The first step includes taking out both the battery tray and battery followed by draining the a/c system and cooling system. Use hose clamp pliers (J 38185) to move the Radiator inlet hose clamp while detached from the upper transaxle cooler line. To perform the procedure proceed with repositioning the surge tank outlet/radiator outlet hose clamp before removing the surge tank outlet/radiator outlet hose. The pool ventilation hose requires removal together with the condenser inlet assembly and cap or tape must cover the ac hose opening for contamination prevention. First remove the surge tank hose bolt from the Intake Manifold before disconnecting the refrigerant pressure sensor electrical connector and discarding the sealing washer. First disconnect the cooling fan electrical connector and lift the vehicle before taking out the lower closeout panel. The hose clamp pliers (J 38185) shall be used to reposition the surge tank outlet/radiator outlet hose clamp while separating the surge tank outlet/radiator outlet hose from the Radiator. The next step involves removing the lower transaxle cooler line together with the evaporator line from the condenser outlet and the lower Radiator support mounting panel. Separate the Radiator from the fan as well as the condenser while working with an assembly unit before removing the Fan Shroud and fan nuts from the fans. Begin by first removing the fan motors and from their respective fans and then continue by detaching the Fan Motor bolts and the fan motors and . Secure the Fan Motor bolts to the fan motors and while tightening them to 6 nm (53 inch lbs.). Place the fans and onto the fan motors and before securing the fan nuts at 6 nm (53 inch lbs.). Reinstall the Fan Shroud before applying assembly containing Radiator and fan and condenser in their original place in the vehicle. The lower Radiator support mounting panel needs to be secured by bolts at 10 nm torque (89 inch lbs. Torque). First remove discharge hose tape or cap then install a new washer before linking the inlet fitting of the condenser to the discharge hose. Use the wrench to connect the condenser outlet to the evaporator line bolt then tighten it to 25 nm (18 ft. Lbs. Torque). The hose clamp pliers (J 38185) should be used to adjust the surge tank outlet/radiator outlet hose clamp position for connecting the surge tank outlet/radiator outlet hose to the Radiator. The technician should install the lower closeout panel then lower the vehicle and connect the cooling fan electrical connection. Reinstall the lower transaxle oil cooler line connecting it with a 30 nm (22 ft. Lbs.) torque while routing the surge tank outlet/run hose to its proper destination on the surge tank. The hose clamp pliers (J 38185) enables you to relocate the surge tank outlet/radiator outlet hose clamp for installation of the upper transaxle oil cooler line fitting which requires a 25 nm (18 ft. Lbs.) torque. Completion of the repair process includes connecting the Radiator inlet hose to its Radiator and tightening the clamp using hose clamp pliers (J 38185) while refilling the cooling system, installing battery tray followed by battery and using halogen leak detector (J 39400-A) to test fittings for leaks on all reinstalled components. The conclusion step includes both battery tray installation followed by battery placement.
