Upper Shroud

Users should start the Fan Shroud service and repair procedure by detaching the air cleaner assembly before removing the air intake duct from the Throttle Body. Start by removing the Coolant Reservoir followed by detaching the bolt connecting the engine oil fill tube and the generator bracket bolts which attach the engine and transmission oil dipsticks. Start by placing the dipsticks with the oil fill tube beyond the Fan Shroud before unscrewing all upper Radiator retaining bolts and bolts that fasten the upper to lower shrouds from their location. First remove the fan and clutch from the engine before moving to remove lower Fan Shroud retaining bolts and finally the lower Fan Shroud itself. To install the lower Fan Shroud first install it with retaining bolts which should be tightened to 8 nm (71 inch lbs.). You should start with installing the fan along with the clutch onto the engine before placing the upper Fan Shroud onto the lower Fan Shroud and tightening the upper to lower Fan Shroud retaining bolts at 8 nm (71 inch lbs.). Apply gm p/n 12346004 sealer equivalent along with similar products to the upper end of the oil level indicator tube at the joint before installing the top section into the lower part. Fix the engine and transmission oil Dipstick bolt followed by tightening the engine oil fill tube bolt at the generator bracket. The last step involves securing upper Fan Shroud retaining bolts to the top of the Radiator since 8 nm (71 inch lbs.) torque is required before moving onto the Coolant Reservoir and surge tank as well as the air intake duct from the Throttle Body and air cleaner assembly.
