Are these the belts I need?

[GeorgiaJeeper93]

So the belts on my 86 Mj are dry-rotted, and I'm in need of some new ones. Problem is, I have too many options. Unfortunately I'm using my phone at the moment so I have no way to upload pictures, but I need the one that has the grooves in it, I belive it's called the v belt. I'm probably wrong on that though. I also need the smooth one. Rockauto has belts for my truck, but some day with ac, others say without and I don't know which ones I need. My truck does have factory ac, power steering, etc. Problem is, I don't know which belt is supposed to power what. Any help?

The Op has an 86 which shouldnt have a 4.0 from the factory

 

Iirc There are several belt routings/configurations in 86 so you may be better taking the part numbers off of your old belts to be sure or what numbers you need .

Edit your signature in the "My Settings" drop-down menu to reflect what year, model, engine, etc. etc. your truck is.

Thanks for the replies. My truck is the 2.5l. I can only read the part number off of the belt with grooves. It's 150430 11AV1090. No idea what to do to get the other one.

The belt number you referenced is a 15430 dayco or a 7430 gates , whichever you prefer ..

[GeorgiaJeeper93]

Anyone know what the other belt I need would be, or how I can figure it out? I'm stumped.

[HOrnbrod]

The below are all the possible belt(s) routings for an 86 2.5L. Which configuration do you have? Let me know and I can cross reference the p/n's for the correct belts. I suspect the 1-2 diagram?

If so:
Belt #1 = Dayco 15430 or Gates 7430
Belt #2 = Dayco 17465 or Gates 9465

Thank you for that. Just curious, when I went to order them, it says w/o ac, but my truck has ac. Is that normal?

How many V-belts does your truck have? Two or three?

[GeorgiaJeeper93]

Only two. And only 4 pulleys

Then the info I sent you is correct for a stock 86 MJ 2.5L w. two V-belts according to the factory parts manual. If it's been modified  :dunno: .

[GeorgiaJeeper93]

Gotcha. I'll roll the dice and order those. I guess worst case, I have no a.c, which is what windows are for anyway. Lol

Thanks for all your help!

So, I'm changing the belts today. I got the alternator belt on without too much trouble. Now I cannot figure out how to get the power steering pulley to move so I can get the belt on. Any ideas?

[GeorgiaJeeper93]

Disregard. I figured it out!
