I don't like expansion valves
So, I took out my 1970 evaporator and put in a 1987.
Just incase anyone else is thinking about it. Also have a sanden compressor and 14x27 Ebay condensor to put in. Already spent some time spiffing up controls and making all the flaps work. More to come as I get more done. |

Re: I don't like expansion valves
I will be doing the same thing when I get to that point in my ls swap. Is there an office in the new evaporator?

Re: I don't like expansion valves
If you notice the crimp marks on the smaller tube of the evaporator, that's where the orifice goes.
I also bought an accumulator and a cycling switch for an 87. |

Re: I don't like expansion valves

Re: I don't like expansion valves
Did this about 25 years ago on my 71. I put the orifice in the line right at the battery tray at the union so it's easy to get to for changing. The system works great. I originally used normal R-12 parts because at the time no kits where available.
Later I bought the Classic Air group kits to get better performance out of the AC.

yes it is very cool! No matter if it's 95* outside my truck runs at 38* inside. I sent them pictures of the truck after installing their kit and was sent a request to put my truck on their cataloge. As you can see I said yes!
