Once and while when I start my truck it will squeak until it warms up. I took it too the dealership and it would not do it then. It does not happen every day, but it is starting to annoy me. Does anyone have a clue of what it could be? Thanks.

oh yeah i have a 04 supercrew 5.4

if it is really cold it will scream a bit- have you payed attention to the times it has squealed?

 

it has only done it in the cold.

 

My sons Ranger did that, only squeeled when initially starting it in the morning. Eventually got worse, ended up being a bad bearing in the alternator.

 

hmmm...mine does not do it everyday, did yours sons?

 

Mine does it on really cold mornings...Like when its less than 10-15 degrees....But it doesnt do it when it is warmer.....

 

Yeah that is kind of like mine...but it will do it if it is about 25 or less

 

sounds like an idler pulley, or compressor pulley if you typically start your truck with the a/c on

 

Mine was doing that when first started on cold mornings. I replaced the serpentine belt with a gatorback and no more squeal. It has only been a month or two, so I can't vouch for it being a long term fix.

 

It started out random, maybe once/twice a week when it was cold out side, it would go away after about 5-10 seconds.... then as time went on, (about 2-3 months) did it more and more, finally the squeal became constant.

 

its definitely the cold- as noted above- mine will scream around 10*F and lower. it will do it for about 5 seconds and will then run normal- im not too worried

to answer hawkpilot, even a gatorback will do it

 

Same thing happened to my Ranger, turned out to a bad bearing in the idler pulley. Could just be your serpentine belt...

 

Thanks guys - i have the edge so I was thinking about a gatorback belt. If it continues i will have them check out the pulleys. Thanks!!!!!

 

the hamsters don't like the cold weather

 

Dayco makes a belt that is exactly the same as the Goodyear belt. It is a Driverite. It is cross checked and the quality is excellent. Mine is due to be changed. It chirps a bit when cold and squeels at WOT with the Edge. About $40 for the belt.
