Ford E5TZ-6068-G Engine Support Insulator Assembly

You can Select Your Vehicle to check if E5TZ-6068-G fits your vehicle.

Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent damage to driveline components. During the check, the engine must be raised slightly to remove the weight from the mounts. Begin by raising the vehicle and supporting it securely on jackstands, then position a jack under the engine oil pan with a large block of wood between the jack head and the oil pan, carefully raising the engine just enough to relieve the weight on the mounts. Inspect the mounts for any cracks, hardened rubber, or separation from the metal plates, noting that the rubber may split down the center. Check for relative movement between the mount plates and the engine, transmission, or frame/body using a large screwdriver or prybar; if excess movement is observed, new mount isolators will be necessary. For front mount replacement, raise the vehicle and secure it on jackstands, then place a wood block and a jack under the engine. Remove the upper and lower nut and washer assemblies from the insulator assembly, and raise the engine just enough to allow clearance for the removal of the mount insulator and heat shield if equipped, with installation being the reverse of removal. For the rear transmission mount replacement procedure, additional guidance is available.

Engine mounts are usually trouble-free, but if some of them are cracks or completely worn out, they should be replaced to prevent further damage or wear of other drive line parts. To check the mounts, the engine has to be lifted a little so as to take the weight off the mounts. First, lift the car and apply jack stands after that, place the jack underneath the engine oil pan. If it has Automatic Ride Control, switch off the air suspension switch before lifting it to prevent the damaging of it's components. Put a piece of wood with about the same diameter as the jack head but wider in thickness than the oil pan separating the two surfaces, then lift the engine approximately off the weight placed on the mounts. Check the mounts for cracks, when the rubber has become too hard and if the rubber mounts have detached from the metal plates a little bit of space is always apparent and the rubber will be split down the middle. Make sure that mount plates move relatively to the engine or frame, if this is observable, then lower down the engine and torqued the mount fasteners using large screwdriver pry-bar. To retard the process of deterioration, then the mounts should be treated with rubber preservative. For replacement, first, remove the negative battery terminal, then lift the vehicle, and set it on jack stands, if the vehicle contains Automatic Ride Control, make sure set the Air Suspension switch off. Loosen the engine electric cooling fan/shroud assembly to reveal four nuts of the mount to the engine bracket which are done from inside the engine compartment on the top. Lift the engine up a little with a jack or hoist, then take off the mount-through bolt/nut and cut off the mount from the bracket of the chassis. Than removal, installation is the opposite; one should apply thread locking on the mount bolts, and tighten them.

Insert a large screwdriver or pry bar into the space between the transmission extension housing and the frame cross member and pry up. The transmission should not move significantly away from the mount; if it does, the mount should be replaced. Place a jack under the transmission with a wood block on top to protect the transmission case, applying a slight amount of jack pressure to support the weight of the transmission. Remove the two nuts securing the mount to the frame cross member and the two bolts securing the mount to the transmission extension housing. On 1997 and later models, there is an exhaust mount bracket under the right-side transmission mount bolt, which may need to be pried aside slightly after removing that bolt. Raise the transmission with the jack until the studs on the bottom of the transmission mount clear the cross member, then remove the mount and install a new one. Installation follows the reverse order of removal.

If the mount is okay, remove the jackstands and lower the vehicle.

During the check, the engine must be raised slightly to remove the weight from the mounts.

A large screwdriver or pry bar should be inserted into the space between the transmission extension housing and the crossmember to pry the transmission up slightly.

Installation is the reverse of the removal steps.

Raise the engine slightly with a jack or hoist and detach the mount from the chassis bracket.

Raise the vehicle and support it securely on jackstands. Insert a large screwdriver or prybar between the transmission extension housing and the frame crossmember and pry up to check for excessive looseness. The transmission should not move significantly away from the insulator. If it does, the mount should be replaced.

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