Chrysler
Engine Mount Noise
I know the majority of
you auto techs are extremely proficient at finding and repairing sources
of strange and unusual noises. Although chasing these audible emissions
can be time consuming and without a doubt aggravating, the customer's concerns
are usually valid and can often be of monumental importance to them.
Let me say something
in their defense. They drive the vehicle every day, and most of them know
when something has changed. Please, give credence to their claims and
do your best to locate the problem. Remember, they wouldn't be paying
you to find a noise if they weren't concerned about it. Chat time over.let's
dig into the details of this tech tip.
Certain 1992-93 Chrysler®
models may exhibit a "clicking or snapping" sound from the left side
of the engine compartment while accelerating or decelerating from a stop.
This noise is more prevalent when the engine compartment is hot.
The 1992-93 Chrysler®
models affected
- Spirit®, Acclaim®,
LeBaron® Sedan®, LeBaron® Coupe (except convertible)
- Daytona®, Sundance®,
Shadow® (except convertible
- Caravan® C/V,
Grand Caravan®, Voyager®, Grand Voyager®, Town & Country®
Diagnosing the
problem
Note: It really helps
to have the customer with you in the vehicle to identify the noise in
question.
- Close the windows
and with engine running, and apply a load to the engine while in drive
with the parking brake applied.
- Release the load
and shift into reverse.
- While applying
a load in reverse, with the brakes applied, listen for the "Clicking/Snapping"
noise.
If noise cannot be
heard, or the vehicle is equipped with a manual transaxle, drive the vehicle
at low speeds with several quick, but not hard, acceleration and deceleration
moves. If the noise is heard, proceed with the following.
Repair Procedure
- Remove the left
engine mount.
- Install the appropriate
revised left engine mount.
- Tighten the long
support bolt to 45-60 ft. lbs.

Here's an installation
note. This engine mount is a new "two-piece" slider type. Once
the long support bolt is tightened to specifications, the split slider
tube locks and will not slide or move within the aluminum core of the
mount. Any engine centering must be done with the support bolt engaged
in the weld nut loosely with no torque applied.
Allow about three
tenths of an hour for diagnosis and about half an hour for the repair
procedure. Your customer will be in awe of your expertise and professionalism
and will be very grateful you took the time to first, listen to them and
second, find their problem and fix it quickly. Great job.keep up the good
work.
