How do you replace a timing belt on a 1991 Dodge Colt Vista?

Sincerely, I recommend you buy a shop manual. Haynes or chiltons

(for the inexpensive cost) are good manuals to consult. I use Motor

or Mitchl manuals.The job you are questioning is quite an involved

one.

You must at least, posess good mechanical skills. As this

proceedure, if not done correctly, will render ur car useless. It

basically involves removing parts and placing them back but, you

must have the proper tools and, the manual in order to see the

pictures or Figs.

Still want to know? Ok. Keep in mind, that this is a 2 man job,

and that this procedure works better for an engine that has the

existing belt still, but will work on one that has broken off. It

just has a few more things to consider.

1- Apply emergency brake.2- Raise vehicle and support with

stand.3- Remove front left wheel.4- Jack up engine a bit, to

relieve weight on motor mount which must be removed on that same

side the wheel came off.

5- Remove #1 sparkplug and bring that #1 piston to TDC. (Top

Dead Center) To do this, have someone tap-crank the engine till u

can visually see the piston come up. Important: #1 piston must come

up on compression stroke!! In order to figure this out, use either

of two ways. Either place a rolled piece of tissue onto the opening

of the sparkplug hole, (as piston comes up on compression stroke

ONLY, the tissue will pop out). Or, if you can block the hole with

a finger (just snug) you will feel the compression blow by your

finger. This SHOULD bring the timing marks to their respective

places.

Note: (If you DONOT feel pressure come out of the sparkplug

hole, you may have really bad piston rings. If so, this work is not

needed, another engine is).

6- Disconnect NEG battery cable.

7- Remove motor mount.

IMPORTANT= Before removing all I am about to explain, you MUST

loosen the Crankshaft center bolt first!! With the help of all the

belts still on it will be hard, but, you must find a way to stop

the lower crankshaft pully from rotating! If this pully rotates,

the #1 piston will loose its correct timing position and YOU MUST

re-do step #5 ((I KNOW, I HAVE DONE THIS)) If you do not have a

tool that can hold the pully, you can try this.> NOTE: some

people use a pry bar and wind up cracking the pully! Don't do it to

that point. This pully has several holes in it. Using a chain, Bolt

it at top where the motormount goes. Bring the slack down along

side this pully. Find a small bolt that will fit in the holes with

out having to screw in. If it does, all the merrier.

8- With the chain in place, place a pry bar (big screw driver

like tool) in between engine and pully (with EXTREME caution)not

crack anything plastic or the edge of the pully, or with causing

warpage. (sorry, this is one way if you do not have that special

tool that holds this pully).

NOTE: you must remove the lower plastic cover under the engine

just in the front!

Now, when you removed the wheel, you did it so you can access

this little hole that is covered by a rubber cap, remove this cap.

Thru this hole you will see the crankshaft bolt. NOTE: if it does

not seem aligned, lower or raise the jack to make it aligned. Place

the correct size half inch socket over the nut. Insert a half inch

ratchet extension, and attach a breaker bar to it. Place and hold

the prybar in place and have the 2nd man turn the breaker bar

counterclockwise until she breaks loose. THIS MUST BE ACHIEVED

9- Now remove belt by loosening the alt tensioner to slack the

belt, and any other component that has a belt (ie, A/C, pwr str

etc). Once this is done, begin lossening the screws or bolts to the

pully of the water pump and crankshaft. They basically have 4

screws ea. Crankshaft pully has the center bolt too, remember! (DO

NOT MIX THEM with others)

AGAIN: DO NOT allow crankshaft pully to budge!! Once the crank

pully is off, you will notice its timing mark by means of a pin on

the gear. Now, the timing mark which is to match with this pin

looks like a pimple and is located at a 1'Oclock position on the

engine. (In other words, look at this gear as if it were a clock.

The little hand MUST be pointed to 1 O'clock. Once the pullys are

off, remove the timing belt covers (2 pcs). There are several 10mm

screws- don't mix them.

10- Now, at the top, you will see the camshaft, which will

reveal part of the belt. What you want to check for is the timing

mark on the belt pully sprocket (THIS ONE STAYS ON -DONOT REMOVE).

This mark is in the shape of a triangle >. This mark must be

pointing to 3 O'clock, at its counter timing mark, which is located

about an inch away on the engine head. AGAIN: You must have a

manual in order to understand this. If it is not, careful rotating

adjustment must be done so that ALL timing points match.

11- Now you must just loosen the timing belt tensioner spring (a

spring with a bolt thru it)

12- Now loosen the timing belt tensioner (the bolt is on the

right side of it)

13- Once this is done, the belt can now be removed.

TO REPLACE.. follow these steps in reverse order. Make sure to

check timing afterwards with timing light.

IMPORTANT: You can tell if #1 piston is at Top Dead Center, by

removing the distributor cap and checking to see, that the rotor

points to #1 wire on the cap. The distributor cap has the numbers

on it.
