Thanks.

I hope it is easier than it looks to replace this.

I have the condeser bolted in place and the lines hooked back up. I must say most of the job was easier than expected, but the replacement condeser was pretty ill fitting.I had to make several modifications to make it work I vacuumed the system for a while to see how tight it is before putting it all back together. I think there may still be a leak somewhere.

Did you confirm the old condenser was leaking? If so, did you use new O rings on the replacement, and tighten the connections carefully? If you have a "sniffer" you can put some refrigerant in the system and leak test..Or the soap and bubbles test.. Do it now before you put it all together..Remember that refrigerant trapped in the oil takes time to be pulled out by vacuum...

If it is leaking, I don't know for sure if it has anything to do with the work I did. This thing has 100,000 miles on it. Wouldn't surprise me if it had more than one leak. I'm going to go see how the vacuum held last night. If it didn't hold very well I'm going to do the bubble test on the condenser connections. These connections had seals that looked like black flat washers. Never ran across these before. I reused the old ones. I looked in my spare seals and didn't see anything like them. I have pre 2005 GM seal kit also and didn't see them in there.

There is also a GM washer kit.. Those sealing washers are used on many GM's from as far back as 95 I believe, on Caprice anyway.. Should never use the old ones...

GM sealing washer kit 05 and prior

That is the kit I have. Is it possible that the factory washers are a little different looking?The factory ones were all black. No shiny metal ring around the outer edge. I looked just a minute ago and found a couple of small sealing washers in the kit that look like they would fit the condenser connections

It lost about 2.5 inches of vacuum last night.

It is all back together and working good. Vent temp of 34 degrees. I replace the washers at the condenser connections. The old ones weren't black after all, just oily and dirty. I think it was also the reason I lost vacuum while it sat last night. I have a couple of worries with this condenser. The brackets don't mate up flat on the radiator. They ride on the ridge where the radiator tanks are crimped to the core. I'm also worried about the bracket that holds the lines to the radiator. The bracket and the radiator have circular indentions for the lines to sit in. On the new condenser the lines are much closer together . There is absolutely no way of making the lines sit in the notches like they should.

Thanks again for the help!

I always bend the lines to fit in the notches on that one- takes a lot of effort- but I don't like to send it out not mounted properly.......I have even done those without removing the radiator- but to bend the lines in it is easier with the radiator out.................

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

I did some bending of the lines. The problem was the block where the lines come together on the condenser was even with the area where the lines were supposed to be going in the notches. With the block being that close it wouldn't allow me to spread the lines apart so that they would fit in the notches. On the oem condenser the line were longer. They stuck out farther towards the engine compartment.
