Thread: Where do I Stick this??????

I can't figure out where to put the r134a into my 97 GTP. I tried the obvious place, the nozzle in front, and it wouldn't take so I was wondering if any could help me out

try the firewall in the middle

yeah you hook it up to the low side when charging it and run the cars ac and turn it all the way cold.

at least thats the way you charge your home ac. i do heating and cooling but dont know much about car ac.

yep, on the 134a car the high and low side hook ups are different sizes. Alot of cars have red and blue caps on the hook ups. R12 cars are a different story, they weren't dummy proof and you had to be more careful with the connectors. A/C systems work basically the same in a house as they do on a car. I pretty sure your right David, you have to charge the system on the low side with the refridgerent in liquid form. It has to be a gas to be on the high side because a liquid won't compress and you will ruin your ac compressor. Hope this helps. Alot of car stuff is hard to explain over the computer.
