• Q: How to replace the radiator fan on 2001 Cadillac DeVille?

  A: Begin the electric cooling fan replacement by discharging the battery negative cable followed by eliminating the upper Radiator support. Empty the cooling system then strip off the air deflector from the vehicle. Start by taking off the engine oil cooler pipe retaining clip and bolt from the Fan Shroud before lowering the vehicle. Apply the hose clamp remover/installer (J 37097-A) model to detach the inlet Radiator Hose from the Radiator housing. The upper engine oil cooler pipe needs removal from the Radiator before taking out the upper transaxle oil cooler pipe retaining bolt from the Fan Shroud. Use the cooler quick connect tool (J 41623-A) to remove the upper transaxle oil cooler pipe from the Radiator while detached from the plastic cap on its quick connect fitting. First disconnect the harness electrical connections of the Radiator fan motors before removing the clips that affix the harness to the Fan Shroud. The two retainers connecting the a/c discharge hose need removal before the two electric Radiator fan mounting bolts get extracted. Position the Radiator fan assembly to the left side of the vehicle before lifting at the right side until it removes completely in a rightward direction. Position the Radiator fan assembly behind the Radiator and move it towards the right side before pressing downward on the right side until the lower feet of the Fan Shroud match the Radiator mounting tabs. The electric Radiator fan mounting bolts need installation followed by tightening to 6 nm (53 inch lbs.). Insert the connectors of both retainer devices into the outer end of the A/C Hose and reattach all wiring harness plugs to the motors before installing Fan Shroud clips. Insert the upper transaxle oil cooler pipe into the Radiator quick connect fitting while pushing until it clicks before gently checking retention and placing the plastic cap on the connector. Screw the upper transaxle oil cooler pipe retaining bolt into the Fan Shroud position with 6 nm (53 inch lbs.) torque specification. Connect the upper pipe supplying engine oil coolant to the Radiator by tightening its fitting to 18 nm torque. The hose clamp remover/installer (J 37097-A) should be used to attach the inlet Radiator Hose to the Radiator before lifting and supporting the vehicle. Put in the engine oil cooler pipe retaining clip along with bolt to Fan Shroud and fasten the bolt at 6 nm (53 inch lbs.). Put back the air deflector together with lowering the vehicle to install the upper Radiator support. To complete this procedure fill the cooling system then reconnect the battery negative cable and verify engine oil level.
