  Q: How to replace the left engine mount on GMC Envoy?

  A:

  A technician should perform these steps to replace a left Engine Mount starting with vehicle elevation and wheel-tire removal. First remove engine shield components together with the lower intermediate Steering Shaft if it is present. Support the engine using a jack stand with a block of wood before removing the through bolt that connects the mount to the frame bracket while the right side through bolt remains loose. The next step requires removal of the heater pipe bracket bolt from the Engine Mount followed by engine elevation with a jack stand to achieve one-sided tilt. Begin by removing all Engine Mount bolts until the mount can be extracted when needing extra reach for removal. The new Engine Mount installation requires a starting step where you should position the first bolt and then move forward with mounting procedures. Both Engine Mount bolts should reach a torque value of 50 nm (37 ft. Lbs.) before engine lowering happens. Install the Engine Mount-to-frame bracket through bolt at 85 nm (63 ft. Lbs.). After installing the engine coolant pipe bracket bolt from the Engine Mount, users need to remove the jack stand before reinstalling the lower intermediate Steering Shaft followed by the engine shield and wheel and tire assembly during vehicle lowering.

  Q: How to replace the LH engine mount and engine mount bracket on GMC Envoy?

  A:

  The replacement process of left engine mount and bracket begins with disconnecting the negative Battery Cable followed by cooling fan removal. Start by disconnecting the manifold absolute pressure (MAP) sensor electrical connector together with its retainer and subsequently remove the MAP Sensor. The left shock module should be taken out before removing the frame mount. Raising the vehicle while removing the right and left upper engine mount nuts will then require the removal of both right and left lower engine mount nuts. Place a jack on the Oil Pan while cautioning against striking the oil level sender to avoid damage. The first step involves using a floor jack together with wood block to elevate the engine until it reaches a position where the engine mount stud can be cleared. Proceed with the removal of the left engine mount from its bracket and then uninstall the left engine mount bracket bolts and left engine mount bracket sequentially. The technician should remove the left frame engine mount bracket bolts and its bracket only if it becomes necessary. Before reattaching the left frame engine mount bracket users must install it with proper bolts which require a torque of 110 nm (81 ft. Lbs.). The left engine mount bracket needs installation by securing it using bolts which should be tightened to 50 nm (37 ft. Lbs.). After placing the left engine mount onto the bracket position the engine on its mounts then install the right and left upper engine mount nuts with a torque of 70 nm (52 ft. Lbs.). Draw up the vehicle after taking out the jack to put on the engine protection shield which needs bolt installation. Lower the vehicle after installing right and left lower engine mount nuts which should be torqued to 70 nm (52 ft. Lbs.). The service technician should install the left shock module together with the MAP Sensor and MAP Sensor retainer and its electrical connector. Before completion install the cooling fan hub nut to the water pump shaft while placing the cooling fan and reconnecting the negative Battery Cable.
