: Vintage air installers ???
Nov 5th, 03, 02:58 PM
Today I installed my evaporator and lines, while tightening the lines, using 2 wrenches as instructions say, the fitting ends coming out of the box flex around a bit, I'm worried that by bending they were weakened where they attach to the coil inside, they appear to be copper tube, am I probably worrying too much? the bent-deflected 1/8 to 1/4 inch total, this is especially aggrevated by the lines themselves when moving them into position...what do you think?

I have installed a complete Vintage Air System in a vehicle myself, and based on this experience, I would say you have nothing to worry about. The amount of bending that you have mentioned should not be a problem......Scott

Thanks Scott, I thought it was easy getting the evap in on the test fit. But do to the way I smoothed the firewall I had to put on the hoses first, resulting in the hoses imposing alot of leverage on the tubes as I was putting the evap. back under the dash....what a pain the rear it was. Another question for you, how tight is tight on the AC lines? Instructions give no torque, just tighten, but dont over tighten.

I had to bend my evaporator line around a bit also. It's soft copper so I didn't worry to much about it.
As far as how much to tighten the lines, I just went till it felt right. With instructions like we have what else ya gonna do? :rolleyes:

I know, some of the instructions might as well be...
1) Remove old system
2) Install our sure fit system
3) Have it charged by AC professional
4) If you have problems, and you will...call us.

Jerry, The o-rings do the sealing so you do not have to get carried away on the fittings. In fact, when I went to replace my Sanden 508 compressor last summer due to a seal leak, one of the hose to compressor fittings galled slightly coming off and I was just lucky enough with a little TLC to get the hose fitting off without ruining it. I may have gotten it too tight during intitial installation.
Also, Jerry, just curious, are you using R-134a or R12 refrigerant. If you are using R-134a you should be using barrier hose (would be supplied by VA if you bought the kit) which requires the right type of fitting and crimp. I had to buy a special crimper (crimps the fitting longitudinally) because no one in the area either had this type of crimper or would let me use it if they had it.

Yes I am using 134a, my hoses are the barrier type with all pre-crimped ends.

Have you mocked up your compresser brackets yet. Mine was a real treat. My compressor is on the drivers side and that is the kit they sent. I have headers and the bracket that bolts into the block does not even come close to working with headers. I had to cut a semi circle out of the bracket to make it fit around the headers :mad: I called V/A tech guy who could not have been any nicer and asked if maybe I had the wrong bracket. He asked if I had vortec heads, which I do. They do not make a bracket for that application... so I made mine work. Then came the power steering bracket. They do not send the correct spacers to make that work so I cut the ones in the kit to make that fit.
The point of all of this is mock up everything with your headers on before you put your motor in the car. It would be a real bummer to have to do it with the engine installed.

My compressor will be on the passenger side, hopefully my brackets will work. I havnt fitted them yet but will test them soon. My engine will be going back in soon, but it is sitting in the subframe and will just roll back under the car. I wont put the fenders and inner fenders on until I have run it and fixed all the leaks. Just waiting on my wheels and brakes.
