How many engine mounts are there - 1989 Buick Park Avenue

It is fairly easy to do if you have a lift, but it is possible to do on the ground with a jack and jack stands. You will need to be able to unbolt both sides of the mount and support the engine with the jack while you replace the mounts. If you download the autozone app to a smart pone or tablet it will give you a repair estimate calculator,

Depends on your car. Some mounts bolt to the frame, some to the engine. Either way. raise the car, set on jack stands. use the jack to raise the engine some. Remove the center bolt of the mount. remove the bolts from the engine or frame. Raise the engine more. enough to get the mount out. replace the mount.

I have no video of the job just written instructuions.

Park the vehicle on level ground and shut off the engine. Raise the front end of the Escort off the ground using the floor jack. Lower the vehicle onto jack stands placed under the frame to support the car.

2Place the jack under the oil pan and raise the lift plate to the bottom of the oil pan. Remove the engine mount bolt using the 1/2-inch socket wrench. The engine mount bolt is in the center of the mount fitting in clear view.

Slowly raise the engine using the jack until the weight of the engine is removed from the engine mount. Pull the engine mount from the fitting and place the new mount in the fitting.

4Lower the engine slowly and insert the bolt into the mounting hole. Tighten the mount bolt to 67.9 foot-pounds using the torque wrench.

5Remove the bolt from the other engine mount the same way as the first one. Pull the mount from the fitting and insert the new one. Replace the bolt to the center of the mount fitting. Lower the engine to the frame and tighten the mount bolt to 67.9 foot-pounds.

6Remove the jack from under the Escort. Raise the car off the jack stands, remove the stands and lower the car to the ground

It sounds like you have had several engine mount failures. The engine/transmission is supported on each end by
* a mount on the engine front to the body
* a mount on the top of the transmission to the body

These two support the engine L to R.

There are also mount(s) to stop the engine rolling back and forth. These are attached to car front and rear sides of the engine block or on the transmission bell housing.

I suspect that another mount other than the one you have replaced is broken.

If all the mounts are in fact OK, then you have another issue. Mounts don't just fail for no reason. You may have an axle with a failed inner CV joint. If this jams, then very high rotational loads are passed into engine mounts. A failed or locking CV will often produce steering wheel virbration or clunking noises.

ENGINE MOUNTS NOT HARD TO CHANGE.YOU NEED TO SLIGHTLY RAISE ENGINE ENOUGH TAKE WEGHT OFF ENGINE MOUNTS WHEN REPLACING THEM.YOU CAN USE ENGINE CRANE WITH SLING OR ENGINE SUPPORT FIXTURE HOLD ENGINE WEIGHT WHILE YOU REPLACE LOWER ENGINE MOUNT BE LOW OIL PAN OR THE TOP STRUT MOUNTS.

REMOVAL

1. Remove the following components.

1. The engine mounting bracket lower nut.
2. The engine mounting bracket lower stud.
3. The engine mounting bracket lower spacer.

1. Remove the belt.

INSTALLATION

1. Install the belt. Install the following components:

• The engine mounting bracket lower nut.
• The engine mounting bracket lower stud.
• The engine mounting bracket lower spacer.

It really is that easy.

These were a real pain in the neck to change, you may want to take it to a shop if you don't have a lot of experience. The hassle of doing it yourself may outweigh the cost.
Here's the procedure, but it is easier said than done:

1. The engine mounting bracket lower nut.
2. The engine mounting bracket lower stud.
3. The engine mounting bracket lower spacer.

1. Remove the belt.

INSTALLATION

1. Install the belt. Refer to Engine Mount in order to install the following components:

It's your motor & transmission mounts - relatively inexpensive.
Here is where you can get all 4 mounts for your car - AUTOMATIC transmission: http://dodge-car-parts.yogiautoparts.com...
If you feel like reading, here is a bit of information about the function of these mounts on a car:

The purpose of engine motor transmission mounts: Most mounts made of metal and rubber, many newer model mounts are filled with hydraulic fluid, some advance hydraulic mounts come with electronic variable speed control by ECM engine control module. The basic design are the same to support between engine, transmission and subframe. They work hard to keep engine and transmission running smooth minimizing the amount of rattling and vibration from acceleration and stops. At the same time mounts are supporting all major power train systems keeping all mechanical components in balance level and position. Motor mounts are extremely important vehicle parts that stabilize and align a vehicle engine inside the engine compartment. Although small in size and relatively cheap in cost, motor mounts can cause tremendous mechanical problems if they break or go bad. Engine motor mounts are small parts that are used to stabilize and properly align a vehicle engine. When motor mounts go bad, they can cause a variety of symptoms, ranging from mechanical damage to excessive engine noise.

There are four total mounts.

1. Upper engine mount located on the passenger side of the engine. Get this at the dealer, aftermarket, especially Anchor brand are garbage.

2. Lower engine mount, often refered to as a "dog bone" mount because of its shape. This one is located on the lower passenger side. You'll have to remove some splash shields to get to it. Aftermarket is OK.

3. Upper transmission mount, also refered to as a "dog bone" mount. Located under the battery.Aftermarket is OK.

4. Lower transmission mount. Located under the transmission. As with the top engine mount, dealer is better quality.

The two dogbone mounts usualy last a very long time, its the others that fail over time. Especially the upper one.

Motor Mount Replacement/Repair

Give Your Engine A New Life With A Motor Mount Replacement
A Motor Mount acts as a security mechanism for the engines, minimizing the adverse effects of frequent vibrations and oscillations that arise when driving the vehicle. No matter how powerful the engine, there is a need for some internal mechanism inside the vehicle to provide strong support to the engine and to protect it from any damage. The Motor Mount serves as essential and rigid structural support systems for the engine, enabling the vehicle to get through the irregularities of the track and other road conditions smoothly and conveniently. It secures the engine and prevents it from serious damage. Moreover, it minimizes vibration and noise on the part of engine.
Due to prolonged usage, Motor Mount will not be able to deliver its services properly. In order to avoid the risk of total breakdown of the engine, the working conditions of the motor mount needs to be checked regularly .Whenever the needs arises it should be replaced as it affects the overall performance and efficiency of the vehicle. Failure of the engine mount can seriously damage the engine .Auto-part replacements ensures the longevity of the engine and it enables you to fully utilize the benefits of smooth drive.
Points of consideration for replacing and repairing

• Cracking of distributor caps needs to be avoided
• Radiator hoses should not be torn.
• Before opening the engine, firewall must be checked for clearance.
• Engine should not be jacked directly by the oil-pan, as the pan may bend.

Replacement Procedure

• First of all, remove the hood and all the parts required for access to engine.
• Remove the engine mount through the bolts.
• Secondly loose the mount to frame bolts.
• Raise the engine slowly towards upward direction to remove the engine mount brackets and then, ultimately remove the motor mount and the engine mount fasteners; the shims locations needs to be noted down.
• Heat shields or Drip shields must be transferred to the new mount after comparing it with old mount.
• Progressively old Mount is replaced with the new one.

Re-intallation of Engine Mount

• Engine Mount brackets, fasteners and shims must be installed in their original locations.
• Mount-to frame bolts should be placed in their appropriate locations.
• Reinstall engine, mount through bolts loosely and allow the vehicle to run two or three times so that engine mount can adjust at their accurate operating locations.
• Finally, the engine is placed in its accurate place by pushing it inside and all the bolts are tightened.
• Make sure that engine is properly aligned.
• Reinstall all the removed parts.
• Reinstall and align the hood at correct place.
