I have a 94 silverado with lq9 and dirty dingo high mount a/c bracket.it is crap it squealed sine I first put it on I called them and they say its the tension pulley I paid $60 bucks for a new on on top of $300 for the bracket,so I tried my ac today the tension pulley got even louder. Has anyone tried the holley or any other ac bracket that has worked well I'm using the r4 compressor need help anyone

 

holley bracket worked great for me. how did you measure for your belt? is it possible the belt is too long? there is an indicator cast into the factory tensioner that will show you if its not the right belt(the marks wont line up)

 

x2 on the belt. The compressor is locking up is it?

 

The belt came from dirty dingo for that set up brand new compressor a/c isn't blowing cold either belt is tight

 

I have the dirty dingo and it works perfect. I know depending an you a/c compressor pulley there is 3 different belt sizes that you can choose from. I have mine on a 1992 1500 pickup.

Gagliano7 that the exact 1 I have I been running it for a year now when I first brought it it came with a spring loaded tensioner it squeak badly dirty dingo say they had a lot of complaints with it so then they wouldn't swap me out so I ended up paying 60 for the tensioner in the pic and it squeak also

 

If the belt is to long will it cause the a/c to work improperly

 

Went thu the squeek BS w/ the Kwik brkt. [Belt changes, idler shimming, etc, all to no avail.] Then, I found that GM had issues w/ the pulley location on the PS pump, that was the real culprit.
I measured the pulley location, and found it to be 3/32" too far off the end of the shaft. Pressed it flush.. Issue solved.

May or may not work for you.

 

My ps pulley is flush with shaft I went to auto store to get shorter belt tried 1 under the belt I had it was to short.the belt sizes on dirty dingo website are too long all of them r longer than the 1 I had to I tried to re tighten the belt I have and squeak got a little quiter for now but a couple days from now it will b loud again,but my ac still isn't getting cold at idle and its cool driving not cold

 

what kind of cooling fan/radiator setup do you have? if theyre electric fans are they set to come on when the a/c is turned on?

 

I have a be cool radiator with 2 electric fans a 14" and 12" the fans comes on as soon as I turn the ac on

 

So do your fans stay on even at hiway speed?

 

No they come on at certain temp unless ac on I called dirty dingo today and they said the ac bracket I have they had a lot of trouble with it and 6 mos ago they redesign the bracket so I'm sol and out 350 dollars with this crap i will never buy from them again I think I'm gonna try the holley bracket

 

Is the A/C system properly charged? If its cool and not cold while driving, and the belt isn't slipping a whole lot, then you have an A/C problem. Have you checked pressures?

 

Going to work on it some more tomorrow got new compressor new lines new condenser new dryer and new heater core gonna check system for leaks and put a vaccum on it tomorrow hope that will work and get a new ac bracket set up

 

It's really not the bracket that causes the squeaking. The toughest squeak to find is caused by the pulleys and accessories not lining up. So the edge of the serpentine belt ends up making all the noise. Make sure everything is lined up perfectly with your crank.

 

That's what dirty dingo said that's y they design a new bracket so I'm stuck with the one I have

 

Put a GOODYEAR GATORBACK belt on it and that will be the end of the squeak. I have been using them for years on any make, any model or any application that squeaks for no apparent reason. I have never had a Gatorback squeak---ever.

What company sells that belt
