Bmw E30 R12 To R134a Conversion

Alright here's a little DIY for retrofitting R-134a in your E30. This is not just a "change the o-ring" type of install, it's a little more than that. R-134a has different characteristics than the R-12 that originally came in our cars.

To make it short, R. This is the official BMW info document on temps/pressures that you should see coming out of your system.

So there you go. Now enjoy the AC in your E30 all summer long. I have a 1989 325is and the a/c is not blowing cold, was wondering if i might as well convert the system from r12 refrigerant or keep it as is?

Has any one done a conversion of their airconditioning from the r-12 refrigerant to the r-134 refrigerant. I can't get any r-12 anymore. I'm looking for some detailed info.

What tubing needs to be changed? Mikey J. Designed and engineered for the enthusiast, this conversion kit offers a complete, plug-and-play upgrade to the A/C system in the E30 to R134a using a modern Sanden compressor, Nissens parallel flow condenser, R134a expansion valve, new R134a lines (inside and out), and all the necessary supporting bracketry. This upgrade will result in colder A/C vent temperatures, less strain on the engine.

In this video I explain how to convert from a dual pressure switch R12 A/C System on an early E30 or E30 M3 to a single R134a pressure switch. Just wondering if anyone has done the r12 to r134a conversion for their ac. is it a do it yourself job or is it very difficult.

Do you need to buy a new compressor if you switch to r134a? where is the best place to buy a conversion kit? any help is greatly appreciated. thanks. Refrigerant Conversion Kits 3 Series E30, E36, 5 Series E28, E34, 6 Series E24, 7 Series E23, E32, 8 Series E31 are designed to convert your vehicle's air conditioning system from refrigerant R12 to R134a.

This will help improve the performance and efficiency of your system, as well as protect the environment. Bought the R134a screw-on fill ports (to convert from the R12 ones), a can of R134a compatible oil and 3 or 4 cans of R143a freon. Didn't change any O-rings or the expansion valve, didn't pump it down to a vacuum.

I just recently retrofitted a R134a Sanden A/C compressor into my '89 325i M20 with stock Oil Cooler lines. There is a bit of modification in order to make this work.
