Squeek/squeel On Startup

[jdubub]

hey guys,

 

I go to start up my truck about 3 weeks ago on a cooler morning when it was about 40 out and i had this noise coming from under the hood for a few seconds, by the time i realized and could pop the hood it was gone.

 

Then this morning, temp was around 70, i used the remote start just to do it and heard it. I killed the motor, popped the hood and cranked her back up. It was coming from lower mid area of the engine. Once again about 10 seconds into it, it quit.

 

The only common denominator is it had rained bothe nights, but wasn't in the morning when i went to leave.

Truck is an 08 5.3L with 56k miles. Very well taken care of

 

Any help or ideas would be greatly appreciated!

wet belt?

Definitely moisture on the pulleys. Nothing to worry about.

wet belt?

 

 

 

That was my initial thought BUT...... In that case if I replaced the belt would that fix it? Belt looks to be in perfect condition, and when i rubbed my finger on it before i started it back up I didnt get any moisture on my finger???

OK. Gracias...... anything to put on them or do to make it stop? Sounds like shit while it is doing it

Sounds like the weather is creating the moisture in the mornings. Can you park inside at night to test the theory? Mine makes a little noise too when there is moisture in the mornings, but it goes away like yours does. I put it in the shit happens category and disregard it.

haha. No unfortunately I have covered but not enclosed to park in. I figured it wasn't anything major, I just hate hearing that damn sound. I also want to burn the shit happens category lol

Old trick my father taught me was to get a bar of soap and rub it on both sides of the belt. Stops the squeak instantly.

[jdubub]

hmmmmm i might try that and make sure and listen for it the next real wet night

The ac belt probably needs to be replaced as it goes twice the distance of the larger belt because it is so small. I would never put anyting on belts that was to be used on older belts, you want to increase friction not decrease it. New EPDM belts will not show any cracks either so we cant use this measure any more to judge the condition of the belt.

I'd check the tensioner... make sure its still got plenty of spring tension.

 

If that's good, i'd pop the belt off and check all of the pulleys to make sure non feel like they're dragging.

 

And with over 50k miles... i'd probably just spend the $30 and toss a new belt on for good measure. It's not difficult, time consuming or expensive...

 

 

Edit: you can also try starting your truck with the serp belt off and the a/c belt on (obviously don't run it for longer than you need to). If the squeal is still there, it's the AC belt... If it's not there but comes back when you put the serp belt back on, then you know its not the AC belt.

mine has a high pitched squeal when its really cold as well.

 

it doesn't sound like belt squeal.

 

more like metal on metal squeal.

hey guys i appreciate it! I think im going to replace both belts right around the holidays.

 

matt how do you check the pulleys and tensioner? with the belts off just yank on it all and see if they wiggle?
