After 4 months im still trying to fix my freon leaking out the back of my compressor. but i can not seem to fix it. a local mechanic told me that i had to have 2 different thicknesss of washers/gaskets behind the compressor, where the lines tie into. and bolt in.

is this true? or is it just the same thickness of washer on both sides.

thanks guys.

UMMM I think they're both the same size

 

ya i figured out they are for sure. why is my **** still leaking then?! if there is new seals?

 

I have had to install them with the same and with two different ones before. Is the compressor rebuilt? You want to make sure where the line set bolts to the back of the compressor that you have the same gap and that it's not sitting crooked. You can usally look where the seal go and be able to tell if you need two different seals. A rebuilt compressor I used needed two different thickness seals.

 

I just pulled the compressor on my brothers 99 T/A with a gm compressor that is bad and it has two different thickness seals. It's too hot for no a/c.

 

Check a/c manifold hoses...

 

waht do u mean the hoses? its deff leaking from the seals?

 

This has been going on a little long don't you think? I gave you advice on how to check it yesterday.

 

what do umean check it? i knw where its leaking from BUT WHY is it leaking there. buying new compressor

 

so i take it you already inspected the obvious? Sux if you install a $300 part that's a PITA and all it was was a simple $60 dollar hose

 

I had that same problem on my S10 when I installed a rebuilt compressor.The gaskets that came with the compressor weren't the right ones, took it to an A/C guy to find where it was leaking from.He changed the gaskets he got from the local auto parts store and recharged.It leaked out after 2 days. I went to an A/C specialty place and they gave me the correct gaskets and it was fine after that. So there are two different thicknesses of gaskets but you should have the same thickness on both sides.

 

Is there something with the hose sealing surface that could be a problem?

 

surface is fine where is a GOOD A/C place in dfw.

 

He's got another thread about this. In that other thread I told him to unbolt the compressor and position it so he could see the back of it, pressurize the system, and use a gas leak detector (soap bubbles) to find the leak.
Thats what the shop is going to do.

I also noted the fact that some GM compressors use different thickness seals and are color coded but ALL LS1 compressors use one seal,,,,, two of the same seal,,,,, one on each line.
This could be a $8 to $60 diy fix if the OP would listen.

 

omg dude. why are u a dick? i need help. why does it matter we knw its leaking from the back of it but WHY?!

 

I'm being a dick for helping you in two different threads?

You've got to be near ******* retarded to not be able to properly change two ******* seals.

You're asking me why it's leaking from the back? How the **** do I know?
I told you to take the ******* compressor off the engine and position is so you can see the back, pressurize it and then PINPOINT the leak.
The back does not mean a manifold seal.
The manifold seals are rubber with steel around the outside edge. They are not 100% rubber O-Rings. LS1 compressors DO NOT have different size seals. Many GM vehicles do but not these.

 

u think im retarted. ive done everything to get my hands dirty. heads cam n20fully bulit motor tranny rear ends. u name it. u think i dont knw wat im doin im just asking what else it couldbe besides the seals and why they keep leaking from I KNW ITS LEAKING FROM THERE I DONT NEED TO PIN POINT IT.

 

Is it getting hot in here or it just me?

 

9000th is on his period and he thinks hes mr goodwrench himself
