My engine just developed a squeal when iam accelarating and get to between 1800 and 2100 rpm what could it be is it my turbo a belt? what do i do about it

 

Possible causes in order of possibility;
Loose or bad belt. If loose, check the auto tensioner.
Bad alternator bearings.
Water pump.
Fan. (remote possibility)

Let us know the cause after you find and fix it.

 

It also seems to do it only when there is load on my engine when i let of the gas and cruise at 1800-2100rpm it doesnt do it would that still be the same problem

 

Turbo boot either developed a small hole, or is starting to work lose.

Your "squeal" is pressurized air leaving the intake system quickly.

Check all rubber boots connecting the turbo to connector, connector to intercooler, intercooler to connector, connector to intake.

Check both visually and "manually" meaning rub your hands all around checking for tears.

Check all clamps connecting said boots to said intercooler parts.

Just an educated guess.


For future posts, it would help immensely if you had a signature filled in, year make and model of truck, 12 or 24 valve, any modifications, etc.

"user cp" button up thar, then "edit profile", fill in box labeled "signature" see below this post for a mighty fine example of a really big signature.

its a 98 24 valve single cab long bed
american race wheels
muffler and cats MIA

 

Ditto on the pressure side of the turbo plumbing and rubber boot(s).

Scared the b'jeepers out of me when I forgot to tighten mine after boost gauge install

 

I checked my turbo boot and my turbo, both my turbo has no up and down side to side or stops in it and my boot was fine i tightend it and it stoped making the a squeal now its making more of a chirp that i can hear just idleing.

 

Should be 4 intercooler boots.

If it's just a chirp at idle, then it is probably your belt.

There are four boots i know were two are. the one just below the turbo and the one just before the inter cooler were are the other 2.

 

See above gleaned from my first post in the thread.

2 on each side, with a hard connector between them.

I took my truck into the shop my noise was either my belt or i had two broken manafold bolts.
