How do you install the serpentine belt on a 2000 ford ranger 3.0?

Answer 1

A source of common confusion: Idler Pulley -vs- Tensioner pulley....

This is for a 3.0 engine, flex fuel, 4WD.

The Idler Pulley is the one on top, closest to you (#1). It's about the size of a Big Doorknob. The tensioner pulley is directly below that one, on a short arm (#4).

If you remove the air intake tube (loosen 2ea 8mm clamps) you can

get a clear view of them.

The diagram should be located on the beam just above the radiator, close

to the hood latch.

Take a 15mm box wrench (and here is a trick) and pick up your handy 13mm box wrench. This trick requires your 15mm to be open ended on the other end.

Take the 13mm box end and hook it onto the prongs of the open end of the 15mm. This makes an extension arm for your 15mm.

Place the 15mm box on the bolt in the center of the Tensioner pulley, with the wrenches protruding towards the drivers side (below the Power Steering pump).

Push down (clockwise, facing the front of the truck) so that the tensioner

pivots on it's arm. This this is STIFF! You'll have to put some weight into it.

Take care that your wrenches are not hitting the frame or something else as you pivot the tensioner.

While holding the wrenches down with your right hand, remove the belt

from the alternator with your left.

SLOWLY release the wrenches (these guys could fly up and hurt you or your truck!!!)

Reverse is the installation of removal.

Follow the diagram in the link for the new belt.

I found the new belt was somewhat shorter than the old one, I suspect

they stretch.

Watch your fingers and good luck!
