Serpentine belt replacement?

Hi and thanks for using 2CarPros.

Because of the routing required, it isn't a good idea to bypass the compressor. Instead, I suggest getting an AC bypass pulley which is about the same price as a belt. Many companies make them. That way you can use the old belt and keep the same routing.

If you look up Dorman part number 34187, you will see a picture of one. I believe that is the one you need, but confirm engine size for your vehicle. Most any parts store can get these. All you do is remove the compressor and bolt on the bypass pulley assembly.

Here is a guide to help change the belt out with the serpentine belt routing diagrams below.

Is the sound gone when the belts are off?

To install, first locate your tensioner pulley, this is a spring loaded pulley that applies downward pressure on the back side of the serp belt, on this pulley you will have either a square drive hole that a socket wrench can plug into, or a regular hex bolt, using the correct size wrench, apply opposite force to relieve tension on the old belt and remove the belt. Install the new belt on all pulleys except the top most one, or easiest one to get at, then while holding the belt in the possition ready to go on the last pulley, apply the wrench to the tensioner pulley and slip belt onto the pulley! Done!

Imma cj guy, I do know some stuff about installing belts

ok, I do not know your rig. But I am assuming you have a spring loaded tensioner. As most newer rigs do.(My dad's '86 t-bird is mechanically tightened)

i use a breaker bar (pull handle) in most cases

sometimes you just cannot get it to fit the nut. Needing just a hair more "twist" to engage the socket,

what I do in such cases is, lever the pulley itself with a handle/board/rod/etc. Just enough to get my socket on

be very carefuldo not "fulcrum" (lever) against your radiator inlet or other stuff that will break!

Respond with wonderful news!

There is an automatic belt tensionier that rides on a shaft. Basically, you turn the tensionier away from the belt to loosten it. When you replace it, reroute the belt and then turn the tensionier to you can slip the belt onto the final pulley. If you need a routing diagram, got to the belt routing diagrams link on this page.

Let me know if you have other questions.

A 5.4 should be a relatively easy job. Toward the left side of the engine is your tensioner. There should be a cover over it. Remove the cover and turn the bolt so that it releases the tension on the belt. After that, pull the belt off and replace with the new one. Make a diagram of the belt's route if you can't remember it.

I have a 4.6 in a Mustang, so mine's not completely the same. But the procedure is the same.

Here is a guide and the diagrams below so you can see how the job is done:

I am finding no six cylinder option in that year F150.

Pick your engine, the diagrams show where you release tension on the belt for removal/installation.
