Many thanks for all the threads and feedback. Benz now blows cold.

Brief history. Car converted from r12 by prev owner. Compressor-drier changed, system flushed, etc. I have owned for two years, ac never cold. Tried a variety of checks, flushes, leak tests, etc, but still Tepid at best.

Did a search and read everything at this site for last year on SD ac.
Evacuated system. Injected dye. Found leak at suction line at compressor. Installed new O-Rings. Leaks repaired.

After much thought and research I am using Freeze 12. Reasons: r12 bad for environmental reasons; r134 did not work; regardless of other's experience, r12 is very expensive here; Had success with Freeze 12 in other applications. Decision made. Purchased Freeze 12 on Ebay for $8/can with shipping.

I even tested Freeze 12 for flammability by running a tiny bit of the stuff into a plastic milk jug and trying to ignite. (outside-wearing face shield, etc) Stuff did not burn.

Last night I had experience of having to 'warm up' the AC settings because it got too cold!!


AC system now cools great except at low (stop light to stop light) speeds. Located a gas benz fan in junkyard and hooked up this morning. Photos attached. New fan is much larger and moves a lot more air. AC is MUCH BETTER. Will probably install an override switch to run aux fan in traffic as needed if thermostat hasn't switched on.


Stylin and running cold. Many thanks again.
