ENGINE MOUNTS

FRONT

UPDATE
Now that I have removed the front mount of a 1993 1/2 model I can describe it better, some of what I wrote a decade ago is confusing and inaccurate (perhaps part of it is about lifting mount back into place).

The mount has a tongue going way up on left side, with 90 degree bend aft. That's key to finding it - it is on the end of the engine below the exhaust crossback tube. (Figure 3 needs studying, diamond symbol C shows the bolt with line through mount's wing and up to engine, mount is shown displaced well down.)
A bolt goes into the engine block through the transmission mounting flange - oriented sideways.
I had the radiator fan out which is easy to do, but I doubt that makes much difference, the bolt was relatively easy to remove.
Fairly long bolt, 18mm head.

(The lower bolts with diamond symbol E going into the engine block are awkward to get at. The bottom part of the mount attaches to the frame with two nuts onto studs - one shown with E - and a bolt shown beside it.
Diamond symbol A refers to the lateral bolt holding the two parts of the mount together (upper part and insulator part).
I am reading the 1994 manual.

OLD WRITEUP
The service manual illustration of the front mount of the 3.3L engine with 4S automatic transmission omits the hard-to-get-at upper bolt (figure 3 of the engine section shows it, location is somewhat high up but below the exhaust manifold, the radiator is close to the engine).
Besides supporting the engine-transaxle combination, you may need a way to move the engine aft so the mount holder can clear the engine bracket, a light scissors jack may work.
Torque from driving the vehicle into position may rotate the engine, I suggest chocking the vehicle and putting transmission in neutral, or jacking vehicle so tires are off the ground. One bolt of the mount holder goes into a captive nut in the front frame, I don't know if there is a way to get penetrant inside the frame. The other two attachments are studs.

If the upper bracket bolt migrated out, as mine had, the way I re-installed it was:
(The bolt goes into a threaded hole in the left end of the engine block, just below the coolant return tube.)
- push engine aft
- take the mount holder off
- remove the lower bolts of the bracket
- hook a stiff wire into one of the holes in the bracket
- support the bracket loosely from below, near its normal position
- pull the bracket up with the wire
- you can get a hand on the bracket enough to line it up with the threaded boss on the engine block (use a small mirror), then thread the bolt most of the way in (thread is 12mm by 1.75mm pitch, 45 mm long bolt fits, I'd go for a bolt without captive washer and use a good lockwasher as Chrysler's captive washer is weak).
- install lower bolts, leave them somewhat loose, tighten top bolt, tighten lower bolts.
(The lower bolts are 10mm by 1.5 mm pitch by 23 mm shank plus allowance for captive washer, I recommend replacing with somewhat longer bolts as they tend to loosen and wear, and with a good lock washer instead of captive washer as Chrysler's are weak. You can pad with extra washers so the bolt does not bottom in the hole.)
