Front Mount

The replacement of the left side Engine Mount starts by removing both wheel and tire together. You should remove the engine shield when it comes with the assembly. Take off the lower intermediate Steering Shaft after removing the bottom midway Steering Shaft. A jack stand with a wood block supports the engine during this process. The through bolt securing the Engine Mount-to-frame bracket of the targeted mount should be removed first as you simultaneously loosen the right-side through bolt. Detach the heater pipe bracket bolt from its position at the Engine Mount. Raising the engine with a jack stand will create a tilting position to one side before you remove the Engine Mount bolts and afterward you take out the Engine Mount perhaps requiring positioning swings for removal. Begin Engine Mount installation by opening the mount as required before securing the mount followed by Engine Mount bolts which should be started from the first position then torqued to 50 nm (37 lb ft). Install the Engine Mount-to-frame bracket through bolt after lowering the engine while tightening it to 85 nm (63 lb ft). After loosening all of the engine coolant pipe bracket bolt from the Engine Mount position it is necessary to take away the jack stand and install the lower intermediate Steering Shaft. Open the engine compartment after reinstallation of both the engine shield and the wheel assembly when possible.

The process to replace transmission mount (RPO Z71) begins by raising and supporting the vehicle. Start by supporting the transmission with a transmission jack before removing the transmission mount's two securing nuts from the transmission support. Lift the transmission away from its support before you detach the bolts which secure the mount to the transmission and remove the mount spacer. Begin installation by putting on the mount spacer and attaching the transmission mount to the vehicle framework. Adhere to the fastener instructions to maintain proper mounting procedure. Follow by screwing in the mount to transmission bolts before tightening them to 55 N.m (41 lb ft). Install two transmission support nuts then torque them to 57 N.m (42 lb ft) using the specified sequence. Use the transmission jack to bring the vehicle down.

A vehicle lift and supporting system should be used to access the left Engine Mount replacement. The first step requires removal of engine shield along with lower intermediate Steering Shaft when present. After supporting the engine with a jack stand and wood block workers should remove the through bolt which secures the mount-to-frame bracket that needs replacement and should also loosen the through bolt connecting to the right side. The heater pipe bracket bolt must be removed from the Engine Mount before raising the engine with the jack stand to enable a side-to-side tilting movement. Work by unboltting the Engine Mount brackets after which remove the Engine Mount while optionally moving it into specific positions. When mounting the new engine component start by positioning it and performing required articulations followed by bolting the parts starting from position while maintaining alignment. Lower the engine following bolt tightening to 50 nm (37 ft. Lbs. Before putting in the Engine Mount-to-frame bracket through bolt and securing both fasteners to 85 Nm (63 ft. Lbs.). Replace the engine coolant pipe bracket bolt while you take away the jack stand before returning the lower intermediate Steering Shaft to its position. You should first replace the engine shield (if applicable) before installing the wheel assembly and tire and then return the vehicle to the ground.
