Air Conditioning Expansion Valve Location

[Russmacman]

Hello all. I have a 78 Magnum with a fresh 400. Has AC and replacing the V2. Ordered a Sanden compressor a looking at a new condenser as well. Photo of original lines when I had 318 in it. I don’t see an Expansion valve on the lines. Is it inside the car? Is it not needed? Just getting parts needed. Thanks in advance.

There is either an expansion valve or fixed orifice. It should be on the high side line from the condenser to the evaporator coil. Probably close to the evaporator or on the evaporator.

When you unbolted the lines at the firewall you should have seen this... The expansion valve...

It is probably still bolted to the evaporator....

Thank you so much. There was so much junk on the sides. I just never realized it. I think I'd like to pick up a new one just because it's so old but in anyone's opinion since it was 'calibrated' for r12 and now I'm putting 134 a should I be looking for something different? Any other advice is welcomed.

I would get a new factory styled one for your car. I used the factory one for my 68 Charger with R134 and it works perfectly. If you can get the 134 O rings you will be golden.

Sounds great. Got one in the cart now. Thanks for your help.
