Odds are that the broken belt took out a vaccume line while it was flailing around,that would be the first thing that i would check for.Any hard plastic or rubber lines that are within stiking distance of the broken belt would be suspect.

Most fords have two probles, one is the belt tension pully is going bad or the alternator is locking up, have them checked or replaced. Some water pumps can also cause belt noises.

Need to know how to put a serpentine belt on a 1995 302 ford motor


Below the altenator is a tensioning pully, insert a 3/8" ratchet or breaker bar in the square hole on the tensioner and release the tension on the surpentine belt and remove the belt. Route the new surpentine belt in place up to the altenator and take the tension off the tensioner and put the belt over the altenator pully. Double check to make sure the belt is riding correctly on all the pullies before starting. Crank the engine over several times before starting to seat the belt. f78f558.jpg

Change alternator


It's easy...
Disconnect the battery
Remove the supentine belt from the altenator pully, you can use a 3/8" drive breaker bar on the belt tensioner, just insert into the square slot on the tensioner and rotate it clockwise.
Remove the power wire and the harness
Remove the mounting bolts 1 under and 2 on the sides.

Just reverse the process to install the new altenator.
Make sure the supentine belt is in the proper position.
Make sure the battery is charged before starting, a drained battery can damage the FETs on the new altenator.

I am tryin to reduce the size of my cerpentine belt by deleting my a/c, powersteering pump, and smog pump on my 1990 ford mustang lx 5.0. How do i route the belt so that everything still spins the rite way...


thats a trial and error job. mark each pully as it is normally and then run a piece of sting to give you your length and possible route taking into consideration slack needed for belt tensioner to act properly

How to remove fan belt on my 1996 ford mustang?


Take tension off the tensioner and take belt off. You put wrench on the bolt that holds the pully on and pull - tension will come off the tensioner and you remove the belt.

How do you adjust tension for drive belt


first you need to figure out if you have an automatic tensioner or an adjustable one. so look at the pullies which ones are not accesories (ie not an alternator pully, power steering.) some pullies will just be on there own not driving anything. is this pully connected to something like this O>o <--this end is the pully.
pully mounting bolt ^ ^arm with hole for rachet
or does it look like the pully is attached to a threaded pole.

the auto adjuster need a rachet to pull back on it (because it's spring loaded) while you install the new belt.

the other need the nut on the pully loosened and the threaded pole loosened will move the pully removing tension from the belt (opposite will tension the new belt).

tighten belt until you can only twist it in half.

I have a 92 mustang lx 4cyl. timing belt broke and now i have the cover and pullys off but can not get the new one on cause it appears to be a crank senser in the way! how do i go about getting it off?


check first if this is called a safe engine first as you do a lot of damage to the engine if the timing belt broke such as valves and otheres
