Ford 9L3Z-6038-C Insulator Assembly

You can Select Your Vehicle to check if 9L3Z-6038-C fits your vehicle.

There are three powertrain mounts on the vehicles; left and right engine mounts attached to the engine block and frame, and a rear mount attached to the transmission and frame. Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent damage or wear on driveline components. During the check, the engine must be raised slightly to remove the weight from the mounts. Raise the vehicle and support it securely on jackstands, then position a jack under the engine oil pan with a large wood block between the jack head and the oil pan, carefully raising the engine just enough to take the weight off the mounts. Check for relative movement between the inner and outer portions of the mount using a large screwdriver or prybar; if movement is noted, lower the engine and tighten the mount fasteners. Inspect the mounts for cracked, hardened, or separated rubber, indicating a need for replacement, and apply rubber preservative to slow deterioration. Disconnect the cable from the negative terminal of the battery, remove the engine cooling fan and shroud, and raise the front of the vehicle securely on jackstands. Support the engine with a lifting device from above, ensuring not to connect it to the intake manifold, and raise the engine just enough to relieve the weight on the engine mounts. For 2WD models, remove the engine mount-to-frame support bracket through-bolt, then the mount-to-engine block bolts, and remove the mount and heat shield if equipped. Place the heat shield and new mount in position, install and tighten the mount-to-engine block bolts securely. For 4WD models, remove the engine skidplate, support the front axle with a floor jack and jackstands, and lower the front axle for additional clearance. Remove the front crossmember and the bolts attaching the front axle to the frame, then remove the engine mount-to-frame support bracket through-bolt and the engine mount to engine support bracket bolt and nuts. Install the new engine mount onto the engine support bracket and tighten the bolts securely. After installing the engine mounts onto the engine, lower the engine while guiding the engine mount and through-bolt into the frame support bracket, then install and tighten the through-bolt nut securely. The remainder of the installation follows the reverse order of removal, after which the engine hoist and jackstands can be removed, and the vehicle lowered.

Rubber preservative should be applied to the mounts to slow deterioration.

Raise the transmission slightly with a jack, then remove the bolts attaching the mount to the transmission. Place a transmission jack or floor jack under the transmission and raise it just enough to allow you to slip the old mount out from between the transmission and the crossmember. Remove the mount bolts and then remove the mount (note that the crossmember is removed for clarity, but crossmember removal is not necessary).

Attach the new mount to the engine block and install the bolts and stud/nuts in the appropriate locations. Tighten the fasteners securely.

Turn off the air suspension system. The switch is located in the area of the right kick panel.

Raise the engine a little at a time with the support fixture, watching for interference with any engine compartment components. When the engine is raised about two inches, remove the bolts retaining the mount to the engine block.

Lower the engine into place, install the through bolts, and tighten them to specifications. Complete the installation by reinstalling all parts removed to gain access to the mounts.

Use a floor jack to raise the transmission until the mount studs clear the crossmember.

The intake manifold, high-pressure fuel pump (for 3.5L models), charge air cooler's tube bracket, coolant hose, cowl panel, air deflector over the radiator, and the under-vehicle splash shield.
