I thought I read a thread about some one who actually installed a rear ac lines with out pulling the engine.

Can some one help me find that?

Thanks.

Greg,

It is easy to mount those with the engine in the car....






The only hard part is getting the KINKS out of those metal lines afterwards... HA HA!!

Seriously, I would like to see this thread too, never tried to cipher that hard on it and maybe it can be done.

See ya soon,

Thanks DR.

I am just trying to figure out if I should go ahead and start lifting the motor.
It HAS to be done by early next Friday, at the very latest.

DR

For what...my sick stupid sarcasm..

OH, the 2 SV OP fittings we discussed are on the way to you.

Thanks.

I really think I remember some one installing the rear lines with out taking the motor out, but my search King-Fu is weak and I know some one can look it up fast.

Perhaps it was this thread?

I only managed to R&R the high side line's rubber section, which in retrospect could have been done in situ. Not sure whether the suction line could be done with the engine in.

Yea, that was it Rob, so let me just get this straight, you were able to get the lines in and out with the engine in the car?

With a lot of trouble I am sure.

Rob Edwards

Yes, but just the high side line. I didn't try to R&R the low side line.

Greg,

I am liking the idea of adding a couple of o-ring unions to those two lines, if you can find a spot that is both accessible and also allows the top and bottom halves to be removed without too much drama.

Ideally you want to keep the number of connections to a minimum, but serviceability is important also, and there are lots of o-rings already.

Here's the link that Rob posted, looks like they have some useful stuff: http://www.docsblocks.com/products.asp?cat=19

Good luck!

I agree with Jim - I would put a couple of joints in the lines.

The high pressure line is in, but the low pressure line is not going to go in with the motor installed and the line in one piece.

I think I have a plan though.

Big Tom will be riding in the cold if it works out.

Greg, you are the man!

That is exactly what I plan to do, I went all over Atlanta yesterday to places that SAID they could fix me right up, and when I actually got there, they wanted to use compression fittings and not o-ring type fittings, which will not work for very long holding r-12.

Here is what I plan to do, on the cut up low pressure tubing there is a weld fitting that I can sweat off, then I can do the same with a nut fitting on one of the lines coming off the compressor, (that one will be toast, but you got to do what you have to when time is short)

It looks like the factory used some sort of silver solder to retain the nuts and fittings on, I got one of the weld fittings off today, and I will try to get the nut off on Monday, if that all works out well, then I will have the fittings to allow me to cut the line and put a union in it.

I have high hopes this will work.

Sadly we are having to use used lines, but they were holding on the 89 they came off of, so lets hope it will hold freon.

We shall see.
