My ’95 Ford F150 has just started to squeal in the front upon start-up, now that the temps have dropped into the single digits. It has never done this in the 7 years I’ve owned it. Sounds like it comes from a belt/idler possibly; however, it stops after running for a couple minutes and the rpm’s drop. The colder it is outside, the worse the squeal gets upon start-up. :ohmy:
Any suggestions?Thanks in advance.

Inspect your belt and drive pulleys.

Here is a simple thing to try. With the engine off take some penetrating oil of some sort and spray a little bit in the bearing on one of the pullys and start it up if the squeal goes away then you found the problem, if not shit the vehicle off and spray another one. (careful not to get too much oil on the belt itself) you may have to spray the oil in behind the pully to get it in the right spot. i would start with the belt tentoner and the alternator those seem to be the most common causes of this on the old fords then move on to the water pump ect. what engine do you have? 351 or the straight 6?
It’s a 5.0L EFI, a 302 I believe. She is a bit slow getting up hills, and that’s without towing my trailer.
I don’t know trucks, not a truck guy, so I don’t know if you have one accessory belt or many but the two suspects would be the power steering pump and the alternator. So, look at the belt at those two locations, checking for wear and tension. Sometimes, once a belt starts slipping it gets polished and won’t stop. Then try new belt(s). If no success there and the belt has a tensioner, replace it.
Try this: just as the squealing has stopped, turn on your high beams and rear window defogger and hold your window opening switches in the UP position for a few seconds. If the squeal comes back, it’s squealing at the alternator pulley. It might need a little tightening up, or even might need a new belt or the stopping of some fluid leaks that are getting onto the belt. Sometimes the pulley gets ultra-polished and a few swipes of #60 sandpaper in the grooves will roughen it up enough so it grabs the belt much better.
Haha yeah the 302 in a pick-up truck is a bit under powered. Another thing to look at also would be the A/C clutch and pully im sure you have been running the defroster and that would make sense that if the clutch is cold it could be making noise and when it warms up it would stop. Let us know how it goes
