I ran across this forum while searching for some a/c help for my 1972 Mercedes Benz 280CE. This is a gray import model that was not officially sold in the US, but there was a 280C sold here that had a carburetor instead of fuel injected.
The blower fan works and it uses an old York compressor that also spins, but I will probably replace it with another york as they are as cheap as chips. It's however missing it's condenser. I could buy a used on from a similar car for about $75 but it's hit an miss. New ones from the dealer run about $1600!
I see that this site sells condensers but not for this particular model. Are there universal condensers available where I can just measure up what I need? I don't mind making my own mounts and I understand that I will probably need the correct hose fittings for the new condenser (and reuse the fittings on the other end). I'm just not sure where to start on this project so I would appreciate any input.
The most import input being how you guys measure up a new condenser, if there are any special fitting requirements etc.
A good Parallel Flow condensor will be the best solution. As for sizing, use the largest unit you can fit in the car. It is impossible to put too much condensor in that vehicle.
LOOK HERE for a selection of PF condensors for your needs.
The york is a good compressor. With a PF condensor, the car can run 134a just fine. Be sure to use the correct oil for 134a when you assemble the system. Don't waste your time or cash on that overpriced 406a junk. 134a has more capacity anyway.
Since the system has been open, you will need to flush the evaporator. The TXV should probably just be replaced, especially if it has been on the road with an open system. A new drier of course, and new rubber lines.
Basically a new system, with the OE evaporator. Should cool well. There will be more questions as you work through this, so I am sure we will see you again. Have fun with your project.
