Freon alternatives?
I'm going to evacuate and recharge the 91 318is in a few days and was wondering about freon alternatives. I'm sure it's R12, but need to verify.
I've used DuraCool in the past with success, but does anyone have experience with alternatives that don't cost a fortune? |

Probably R134a in 1991.

You might be right. I was thinking the European cars might have changed over earlier.

I checked the engine bay and did not find a freon sticker. A kook at the manual or in-line should determine that.
Anybody else with ideas? |

You can tell by the fittings on the charge ports. Small ports that are threaded; for R12 vs larger quick-connect nipple style on the R134 systems. But unless it has been converted the 91 318 is R12. You could be in for some expensive repairs sadly. Plenty of threads here on pelican for alternate gas sources and what to do with these r12 systems.

I used something called Freeze 12. Cheap and works great.
Not ready to convert just yet...

I think it is called DuraCool. It is mostly propane with a little isobutane mixed in. Works excellent. Cheap! You car may be a little more volatile with it but I expect not much.
Good luck. Larry |

Have used ES-12 for years and very happy with it. It mixes with R-12 and its molecules are larger than R-134 so it does not leak out as fast if you have a leak.
Cools well and thats a must here in the desert in the summer.

Thanks for the info.
I saw a small and large threaded fitting. One (largel) went from the compressor to the interior and one (small) from the receiver dryer tirades the interior. It blows cool, but not cold. Compared to the 911, it's artic cold. With a 20 year old car, I'm sure it needs some work. As mentioned, hopefully a new receiver dryer, an evac and new freon will get it colder.... Quote:

Duracool worked well for my 924S, but I converted the wife's Volvo to 134a / changed out all the o rings.
Better get on it... this week looks like a hot one.

My 1993 Honda Accord was R12 and required conversion.

Maybe a 92' sold as a 93?

Production and importation was banned in the US on 1/1/96.

Freeze 12 is a solution, but renders the existing R 12 un recoverable as I suspect the other substitutions do. If you're a greenie, get the real R 12 out and recharge with all Freeze 12. At least tell any shop that you may use down the line that you have adulterated your coolant.
