2007 Buick Lucerne Fan Shroud Parts and Q&A

• Q: How to replace the fan shroud (L26) on 2007 Buick Lucerne?

  A: The procedure for Fan Shroud installation (L26) begins with disconnecting the negative Battery Cable and taking off both the condenser and upper tie bar. Start by draining the cooling system before removing both the transmission heater pipe bolts and front air deflector from the Fan Shroud. Use the hose clamp plier (J 38185) to relocate the Radiator inlet hose clamp after which you should disconnect the hose from the Radiator. To reach the transmission oil cooler lines one should move the caps rearward before removing those lines which extend from the Radiator. The wiring harness electrical connectors need removal from cooling fan motors before unclipping their harness attachment points on the Fan Shroud. Open the Fan Shroud mounting bolts with caution to protect both the Fan Shroud attachment points at the bottom and the Radiator. Position the Fan Shroud assembly toward the left vehicle side before lifting it upward from the right side until complete removal. Start installation of the new Fan Shroud assembly by inserting the cooling fan motors first and be cautious to protect its lower mounting points. Use only the special length bolts during reinstallation of the Fan Shroud assembly to keep the Radiator end tanks safe from damage while you align the lower feet with the mounting tabs behind the Radiator assembly. The Fan Shroud mounting bolts need to be tightened at 6 n.m (53 lb in). Connect all wiring harness electrical connectors to both cooling fan motors before fastening wiring harness retaining clips to the Fan Shroud. Insert the transmission oil cooler pipe into the Radiator quick connect fitting until it creates an audible click followed by installing the plastic cap on the joint. The hose clamp plier (J 38185) will reinstall the Radiator inlet hose clamp after fitting the hose into place. After raising and supporting the vehicle you must install the transmission oil cooler pipe retaining bolts to the Fan Shroud and tighten them to 6 n.m (53 lb in). The hose clamp plier (J 38185) provides assistance for relocating the Radiator outlet hose clamp while installing the hose. Installation of the front air deflector should be followed by lowering the vehicle and installing both the upper tie bar and condenser before cooling system filling and reconnecting the negative Battery Cable while inspecting transmission oil levels.
