You will need to order an AC delete idler pulley kit that bolts in place of the AC compressor, there is but one belt for both with and without AC. A company called DORMAN auto parts makes these, contact a local Napa or Carquest for application catalog.

1995 F150 Ford pickup 5.0 L engine can I bypass the air pump pulley and the AC with a serpentine belt and how long is it

There are some bracket kits to bypass A/C pulleys but unknown for air pump pulley. Will help by saying when you get a new serpetine belt be sure that the grooves match the pulleys. What you have to worry about is the speed of the alternator and water pump and steering pump when the belt length is changed. You may over or under speed the steering pump and have too much or too little power assist at different speeds.

Easiest way to measure this is by removing old belt, (take photo for routing first) and then use rope to do trial routing. Once you get the spring on the idler arm to fully tension for rope you should be pretty close. Then slip off rope and measure length. Do not start engine with rope in place.

I had to get my Dodge Dakota toed the other day because the AC pulley locked up and slung my belt. I bought a bypass belt but when I started it just has a loud clunk is it battery or starter?

battery's dont clunk ---a starter can clunk --a seized engine can --so can any component in the engine compartment --does the engine turn over --are you sure it was the a/c pulley that threw belt --is the bypass belt on correctly --

Seized air conditioner compressor

If the compressor is seized, you will know when you turn on the AC, as the belt will shriek like a banshee usually. And yes you can usually just bypass it with a belt for the same model as yours without AC. If there werent any built without AC, you can try another model with the same engine. If all else fails, you can use a small mason's rope to pass through the pulleys without the AC and mesure the length of the rope needed to do so, then count the number of ribs on the original belt. Any good counter parts guy will be able to find you a belt that will fit the measurements as close as possible.

The ac compressor is seized .I need to replace belt but I need to bypass the ac pulley.Do i need to buy a bypass pulley?

If the pulley on the compressor will not turn freely, then yes if a bypass pulley exists you would need to use it in place of the compressor.
If the compressor pulley turns but the compressor is locked up, just unplug the compressor clutch.

Questions about ac pulley and belt?

the defrosters run with the ac compressor running whenever its 49 degrees and higher. it does that to get rid of humidity faster. the pulley works off the ac clutch behind the pulley so you have a locked up clutch. find a belt to fit by bypassing the ac compressor will do if you like

A/C compressor pulley is seized and burning the serpentine belt

yeah its seized up[ and they dont make a repair kit for that one either. they have at most auto parts stores an ac bypass pulley . its a bracket and pulley so you can bypass the factory ac unit and still run the factory belt. but if you decide to change the ac unit there are 5 bolts holding the unit down .have the system evacuated.loosen belt and drop down out of your way. take the ac lines off the compressor and set aside . there are two bolts on top in front and there are 3 bolts in back on top tieing together a triangle shape mounting plate , take all 5 loose and out.disconnect ac wires (snap clip) lift , lightly pry off old ac unit.set aside and reverse the procedure to install your new or salvage yard ac unit. refrigerant chargers can be purchased from wall mart ( there cheaper) at $30. roughly 2 1/2 cans will completely fill the system just follow on label instructions. its all easy to do if you can use wrenches and have a little knowledge. and you get the satisfaction of doing it yourself. and save a bunch of $ along the way.
