ken800,

Dennis said what I was "kind of" saying in my earlier posts. But we still haven't come to a solution to the screetching problem.

Also, I'm sorry, ken800. I didn't even realize you were the original poster in the hyperlink. I'm going to make the edit next. Why'd you let me make a fool out of myself? JK. Don't reply to that.

I had a similar problem when I installed a sonax shift valve in my trans. The belt would screech on a hard acceleration (1st-2nd) shifts. All I did was buy a new belt and problem was solved. As for it being the wheels spining I THINK NOT!!!the sound comes from under the hood unless Matt90gt trucks is a front wheel drive.

 

You guys are a riot! Thanks for the hints. I will consider changing out the belt but only after I try a little belt dressing. If that fixes the prob, I will try a new belt.

Gee, if I add a supercharger, what happens then? Not belt screech, I would assume a full belt rotation or two during shift? LOL.

Thanks again for the input

Not to insult anyone, but serpentine belts slip...Fact....

When they first brought out high speed tests of the different blowers mounted on a 5.0 liter Mustang..I believe every belt in the test slipped except one belt which had the cog style belt...

These belts slip and what makes it worse is the changing loads imposed on these belts....

Using high speed photograpy and pressure vs. rpms they were able to tell these belts were slipping. Even after they tightened them some of them still slipped and they could not get them tight enough to stop them from slipping...

There is a tremendous varying loads on these belts..

You will hear them squeall on a damp(high Humidity) mourning

Change them often...
