Mount Bracket, Passenger Side

The replacement procedure for right engine mounts begins with proper vehicle elevation at the front wheelhouse opening for 2WD cars and full tire and wheel removal for 4WD systems. Start by removing the tire and wheel of the left front position followed by removing the push pin retainers on the wheelhouse inner panel and the wheelhouse inner panel itself. Use the wheelhouse opening to remove first the engine mount heat shield bolts after detaching the heat shield. The procedure starts with engine mount-to-engine mount bracket bolt removal and continues with the oil pan skid plate bolts together with plate (if present) as well as engine shield bolts and shield. Rise the engine only high enough to accomplish the separation between engine mount and engine mount bracket. A suitable jack should be used to raise the engine first before disassembling the engine mount-to-engine bolts and removing the engine mount followed by the engine mount bracket through bolts and bracket itself. To install the bracket begins with mounting it to the frame while first removing all traces of original adhesive before cleaning bolt threads with denatured alcohol and applying thread-locker GM P/N 12345382 (Canadian P/N 10953489) to the bolts. First install the engine mount bracket through bolts in a loose manner while positioning the engine mount next to the engine and loosely installing the engine mount-to-engine bolts. Tighten the engine mount bracket through bolts to 75 Nm (55 ft. lbs.) while engine mount-to-engine bolts require 50 Nm (37 ft. lbs.). Position the engine shield before tightening its bolts to 20 Nm (15 ft. lbs.) and proceed with engine lowering. Users should install the available oil pan skid plate before applying 20 Nm (15 ft. lbs.) torque to its fasteners. The engine mount heat shield goes on first with subsequent installation of the engine mount-to-engine bolts that need tightening at 65 Nm (48 ft. lbs.). To complete the task reinstall the wheelhouse inner panel while also reinserting the wheelhouse inner panel push pin retainers. Finally, install the left front tire and wheel and lower the vehicle.

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

Raise and suitably support the vehicle, then remove the tire and wheel, followed by the inner wheelhouse panel and the engine protection shield if equipped.

Remove the engine mount to engine bolts and take out the right engine mount.

Take note of the Fastener Notice in Service Precautions.

Finally, install the engine mount.

First, remove the engine mount heat shield if equipped, and then take out the engine mount-to-engine mount bracket bolts.

Use an adjustable (screw type) jack stand to support the engine, not the crankshaft balancer or oil pan.

Apply threadlocker GM P/N 12345382 (Canadian P/N 10953489) or equivalent to the bolts.

First, remove the engine mount and the engine mount bracket bolts, then take out the engine mount bracket.

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

Remove the engine mount-to-engine mount bracket bolts and the engine mount bolts.

Reinstall the wheelhouse panel and the tire and wheel before lowering the vehicle.

Tighten the engine mount bracket through bolts to 75 Nm (55 ft. lbs.) and the engine mount-to-engine bolts to 50 Nm (37 ft. lbs.).

Install the engine mount.

Lower the vehicle.

Finally, install the engine mount.

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

Install the oil pan skid plate and bolts, tightening them to 20 Nm (15 ft. lbs.).

Raise the vehicle and remove the tire and wheel, followed by the wheelhouse panel.
