To BimmerNut Ed...Registration Poll...the verdict is in...

[Bimmer Nut Ed]

I just ordered a conversion kit for my daughters AC. Maybe if that goes well, and Abnormal's 525 is still available, I'll reconsider. You're right, the price is right, but I'm afraid of the AC problem.

My 1990 535 also blows real, real cold with R12, and I've never filled it either since I bought it in 2000.

Ed...I see. Abnormal's car is relatively low mileage for a '90 525i, resonably priced and only a stone's throw from where I live. Had I not bought my little Saturn runabout, I would have jumped on it. I am not a big AC guy either and yes it can be pricey but perhaps the R12 has leaked out unless you heard otherwise. I am pretty astounded that my original unmolested 90 735iL R12 system still works great. I even picked up a can of R12 in anticipation of charging it at some point but its still blows cold. Remarkable for a 14 year old car that has never been charged in the 6 years I have owned it.

e34/32s easy, blow the system free of oil or use a flush gun (i paid $125 for the gun and a gallon of flush at napa, flush goes for around $50 a gallon you don't need that much, i use it a pint at a time, i double flush the evap and cond) use the good heavy steel fittings that have their own seals and valves and remove the old r12 valves before you install the new fittings, drain the compressor of all oil and refill with 5-6 oz of ester oil. besides that it's just replacing the drier and exp valve, lube the o-rings with ac oil before installing and that's about it
