Engine Size: 3.0
Refrigerant Type: r134a

Is there a site that might provide a capacity for older vehicles?

1984 Mercedes 300TD? using r134a?

I searched the site and came up with nothing

I doubt you will ever find a website showing conversion capacities considering this was an R12 designed system. If you do please let us know!


When considering your next auto A/C purchase, please consider the site that supports you:

Well, I've been told that with r12, the system should be at 2.6lbs, should it be the same with r134a, more or less?

Actually that vehicle does not convert well to 134a. It would be a good idea to charge it with R12.

You should have a sticker under the hood that shows the refrigerant charge. Which compressor do you have?

I had a 1984 300D that I rebuild the AC system & load with 134A & had it down to 50 @ 85. I replace the condensor with a parallele type, & use field replacable hose & fitting from areoquip(E-Z clip). Work good.
