Did you not put a new water pump in when you had the block built? I have heard bad water pumps that squeak.

So you're AC compressor isn't hooked up at all? If it is, it may be the pulley on the AC compressor.

 

You replaced the tensioner or the tensioner pulley? Could be a bad tensioner. Before replacing anything try taking the belt off and cleaning the pulleys and the belt.

 

I don't like the idea of spraying any sort of lubricant on belts. The most common cause of squeaking belts is slippage. Armor All may make the sound go away but it may also be adding to the problem.

 

i was just trying things with the armor all i was only using a very little bit like a very little yes the ac is off the car completely i have the ac delete belt on the car from gates. it is not anew water pump still the stock one it has about 40 k on it. i tried the belt spray it made it way worse. and it is a new belt on the car also. i used a tensioner and a idler pulley froma buddys evo that was running at the time of the switch sound still there.

 

If you sprayed the belt, it's already too late.

Try this, use a wax crayon while the belt is spinning(note ribbed side). Also note: watch your fingers!!!

Note: to be done by a professional grease monkey!!(my disclaimer)

If the sound goes away with the wax, it is the belt.

Then just clean off all of the pulleys with a wire brush and put a new belt on.

Good luck..

 

I'm not familiar with evo engine, but can the pulleys be misaligned? My Ford Cosworth also makes whining noise and I just noticed that my pulleys are misaligned and I'm guesing that is the cause of my noise.

 

When you inspected pulleys did you see any abnormal wear anywhere? Try using shop solve or brake clean to clean off the pulleys and see if that helps.

 

i cleaned off all the pulleys today with brake clean i tested them there was no drag on them they spun fine. so should i get a new belt and try cleaning off the pulleys one more time the sound comes and goes now. i also looked at the water pump no leaks and that pully also spins fine. anything else guys i am missing i appreciate your help a lot i really do. let me know what you guys think.

 

old school and used car dealers rub bar soap and it goes away.

 

thanks guys the wax crayon fixed it. i will get a new belt this week thanks i guess this belt was bad because as soon as installed it squeeked thanks again.
