  Q: How to replace the radiator fan and shroud for the LZ9 engine on Chevrolet Uplander?

  A:

  Starting the process of lz9 engine Radiator fan and shroud replacement requires first removing the air cleaner and duct assembly. The first step is to detach the right side diagonal brace and afterwards remove the Radiator inlet hose. Engage first by disconnecting the Radiator fan harness electrical connection then loose the engine mount strut nuts that are present on the engine side. The entire mount strut bracket brace bolt withdrawal process starts with removing engineering-based bolts from the Radiator support's top section while rotating these struts until they position themselves backward. First detach the overflow hose from its retainers then disconnect the Radiator outlet hose retainer which is attached to the Fan Shroud. Unbolt the battery before disassembling the Radiator upper mounts together with their respective bolts. You should first remove the Radiator Fan Shroud bolts after which you should disconnect the upper transmission oil cooler line running to the Radiator. Support the vehicle while raising it and detach the Radiator air baffle together with toc lines from their Fan Shroud retainer clip. Finish installation by lowering the vehicle to remove the Radiator Fan Shroud and fans. Once the Radiator Fan Shroud and fans are placed correctly follow installation steps by raising the vehicle to attach toc lines to the Fan Shroud retainer clip. After the installation of the Radiator air baffle you should lower the vehicle while connecting an upper toc line to the Radiator. Seamly fasten the Radiator Fan Shroud bolts at 6 n.m (53 lb in), followed by Radiator upper mount installation with upper mount bolts secured at 10 n.m (88 lb in). After reconnecting the battery and attaching the Radiator outlet hose retainer you should install the overflow hose on its retainers. You should first position engine mount struts brackets against the upper Radiator support surface before bolting the engine mount strut bracket brace at 28 n.m (21 lb ft) and tightening the engine strut mount nuts to 48 n.m (35 lb ft). The last steps include reconnecting the Radiator fan harness electrical connector and installing the Radiator inlet hose before you put back the right side diagonal brace and the air cleaner along with the duct assembly.
