How to replace the left engine mount on 2004 GMC Sierra 1500?

Begin left Engine Mount replacement by removing both the Engine Mount heat shield if installed then disassembling Engine Mount-to-Engine Mount bracket bolts. The front wheelhouse opening can be accessed when elevating a 2wd vehicle but the front tires and wheels need to be removed on a 4wd vehicle before proceeding. The installation starts by removing the left front tire together with its wheel. Then the wheelhouse inner panel push pin retainers and the panel follow before removal. Release the engine shield bolts then remove both the engine shield while abstaining from lifting or supporting the engine through its crankshaft balancer or Oil Pan. The support of the engine requires adjustable screw type jack stands that will allow you to remove the Engine Mount bolts. Before removing the 4wd vehicle's left Engine Mount drivers must eliminate the front propeller shaft. Install the new mount by placing it to the engine before torquing the Engine Mount bolts to 50 nm (37 ft. Lbs.). Return the engine to its original height when you remove both the jack stands along with the front propeller shaft. Secure the engine shield in position followed by bolting its install while tightening its bolts to 20 nm (15 ft. Lbs.). The procedure includes mounting the engine shield with 20 nm torque then moving to lower the vehicle and set the Engine Mount-to-Engine Mount bracket bolts to 65 nm before adding the left front tire and wheel and wheelhouse inner panel push pin retainers and finally lowering the vehicle.
