OK I think I am on the right forum now.I just bought an 86 F150 4X2.It only has one v-belt for the fan.It has A/C so it has to have at least one more and likely 2.Does anyone have a pic of the belts routing and maybe sizes.It has a 5.8 L (351cid)
I likely will have many more questions and some answers,so I look forward to visiting often. Thx George

 

well you should have 2. one will be from the fan to the alternator (and smog pump if equipped) and the other should be to the P/S pump (if equipped) and the A/C (if equipped and in your case you said you do have it)

 

Now that I took a close look I do have 2 belts but they are now routed that way.There are 3 pulleys on the crank end.The inside one has a short belt to the altenator.The middle one is empy but looks like it lines up to the air pump.The outside one runs the fan and the power steering pump.The A/C comp looks like it lines up with the idler pulley and the altenator.Looks like someone changed things around.Living in west Texas I kinda like to get that A/C working,by next summer anyway.
Did I read you right that you are going into the Army??
