I haven't worked on an engine in about 30 years.
I just bought a used dodge ram 1500 with a 318.
The alternator is shot.
I can not find out how to release the tension on the fanbelt.
I'm use to the curved bracket that the alternator mounts on.
Could someone explain this to me?
I saw in one of the questions that there is a diagram under the hood around the radiator. There is a sticker missing and it must be that one.
Any advice would be appreciated.
Thanks, dann

I believe there is a tension pulley located near the starter with a nut on it, this usually needs to be "pulled" to relieve the tension. From there the belt should slide off. I think this is all I did when I changed the belt in my 318. May vary from year to year tho, not sure. good luck

There should be a place on the idler pulley mounting bracket (that is spring loaded) that has a 1/2 inch square hole that will accept a 1/2 inch breaker bar.

what model is it? the '70 models only had two bolts that held the alt in place one on the curved bracket one long bolt the went into the head ...the newer models with the serpentine belt use a tensioner it is located on the passenger side . i use a pair of 18" channellocks and put jaws under the tensioner and push away to the top towards drivers side. do you have a diagram that shows how to put the serpentine belt back on correctly? if not one on top of the radiator or on hood then draw a diagram before you take it off. to put the belt back on route all of it but the tensioner and push away as you slip the belt on.and don't get them piggies under the belt while you are doing this as it will bite good luck
