I recently replaced my alternator and wanted to replace worn out serpentine belt. Got the old belt off, guided the new belt on and there is absolutely no tension on the belt. Do I need a new tensioner. If so how does the old one come off. I'm new to this and would appreciate the help.

I have a 1995 mustang gt 5.0

Is the belt too long?
does it take a good amount of effort to pull back the tensioner?

Did you compare the new and old belt length before installing? When I removed my smog pump I took the old belt, cut it and routed how I wanted it. Then marked it for the length I would need (assuming tensioner mid way). I measured the length to the end of by the cut end and went to the parts store and asked for the closest belt to the length I needed - don't remember what it came from, but it wasn't even a Ford.

The new belt is the exact same size as the old belt. I can move the tensioner with hand

What about the wheel on the alt. Same size . Do you know how to grab the tensioner with a wrench/bar to pull it back.

It's probably ok, but hard to explain with words. You may have to U Tube it with the tensioner. Belt goes on. Tensioner goes up with the help of a wrench/ratchet and comes down on the belt

Apparently my ex-husband made that mistake.

I know this sounds condescending, but make sure the belt is routed correctly.

If you can move the tensioner easily by hand you need a new tensioner.

Depends on how strong your hand is. I can do it with "my strong hand."

Use a piece of string to measure the length around all the pulleys. Then go to the parts store and get several different sizes. Use the one that fits, return the other ones.

Worked for me.
