Mount Bracket, Driver Side

One must elevate the vehicle to replace its left engine mount when working on a 2WD car through the front wheelhouse opening while doing so through the front tires and wheels on a 4WD vehicle. Start with removing the left front car tire along with the wheel followed by releasing the push pin retainers attached to the wheelhouse inner panel and removing the panel itself. The bolts for the engine mount heat shield must be accessed through the wheelhouse opening before removing the heat shield. The installation begins with unbolting the engine mount-to-engine mount bracket and proceeding to remove the oil pan skid plate and its bolts when necessary. Move on to remove the engine shield bolts while also taking off the shield. The engine should be lifted only to a height that achieves separation of the engine mount from the engine mount bracket. Lift the engine with an appropriate jack before taking out the engine mount together with its bracket. Start by removing first the engine mount to engine bolts and the engine mount itself then proceed with removing the engine mount bracket through bolts and finally the bracket piece. The first step for installation is to place the engine mount bracket onto the frame while leaving through bolts loose. Place the engine mount to its proper location on the engine before installing the loose engine mount-to-engine bolts while tightening the engine mount bracket through bolts to 75 Nm (55 ft. lbs.) and engine mount-to-engine bolts to 50 Nm (37 ft. lbs.). After installing the engine shield bolts to 20 Nm (15 ft. lbs.), both reduce the engine. You should install the oil pan skid plate along with its bolts before applying torque at 20 Nm (15 ft. lbs.). The next step involves putting on the engine mount heat shield and fastening the engine mount-to-engine mount brackets by tightening them to 65 Nm (48 ft. lbs.). After installing the wheelhouse inner panel users must secure push pin retainers before putting the left front wheel and tire back on and lowering their vehicle.

Begin the replacement of the right Engine Mount by performing manifold removal for 4.8l and 5.3l and 6.0l engines or proceeding with 8.1l engine removal. Start by removing the bolts which join the mount brackets for the engine. Raise and support your vehicle before you remove the tire along with the wheel. Begin by removing both the inner wheelhouse panel together with the engine protection shield if this equipment is installed. The crankshaft balancer and Oil Pan must not be used to elevate or maintain the engine during this process. Before proceeding attach adjustable screw-type jack stands to support the engine before you take out the right Engine Mount by removing its Engine Mount bolts. Place the right Engine Mount onto the motor so you can insert and tighten its bolts to 50 nm (37 ft. Lbs.). Lower down the engine before taking out the adjustable jack stands. You should attach the Engine Mount-to-Engine Mount bracket bolts before torquing them to 65 nm (48 ft. Lbs.). Proceed with reinstallation of the Exhaust Manifold for 4.8l, 5.3l, 6.0l engines or 8.1l engine followed by the inner wheelhouse panel and tire and wheel assemblies with the option for engine protection shield if present before lowering the vehicle.

Install the engine mount heat shield, followed by the engine mount-to-engine mount bracket bolts, tightening them to 65 Nm (48 ft. lbs.).

Remove the engine mount-to-engine mount bracket bolt, and if applicable, the oil pan skid plate bolts and plate.

First, remove the exhaust manifold and the engine mount-to-engine mount bracket bolts.

Install the engine mount bolts and tighten them to 50 Nm (37 ft. lbs.), then lower the engine and remove the adjustable jack stands.

Tighten them to 75 Nm (55 ft. lbs.).

It is crucial not to raise or support the engine by the crankshaft balancer or oil pan; instead, use adjustable (screw type) jack stands to support the engine.

Clean the threads of the bolts with denatured alcohol or equivalent and allow them to dry.

Ensure all traces of the original adhesive patch are removed, clean the threads of the bolts with denatured alcohol or equivalent, and allow them to dry.

Install the engine mount.

Position the engine mount to the engine and loosely install the engine mount-to-engine bolts.

Remove the engine mount bracket bolts before taking off the engine mount bracket.

Reinstall the front propeller shaft.

Install the engine mount heat shield, followed by the engine mount-to-engine mount bracket bolts, tightening them to 65 Nm (48 ft. lbs.).

Ensure the vehicle is raised appropriately: for a 2WD, lift it to access the front wheelhouse opening, and for a 4WD, raise it to remove the front tires and wheels.

Position the left engine mount onto the engine and secure it with the engine mount bolts, tightening them to 50 Nm (37 ft. lbs.).

Tighten them to 75 Nm (55 ft. lbs.).
