Freeze 12 in Chevy Blazer

WAIT!!!

Freeze 12 IS compatible with R12 OIL, NOT R12 coolant itself! The system must be vacuumed down and emptied BEFORE Freeze12 is put in!

I am doing the same thing to my '88 'Burban. A local shop does it here and gave me the skinny on the whole thing!

All it takes to change over to R134a is evacuating the system 2 or 3 fittings and a valve core removal tool (One can be made relitively simply using a cheap small screw driver and a hack saw to make a slot in it.) anyway remove the valves install the fittings and fill the oil and R134a and you have a working system. $35-$40 kit. Then anytime you need a recharge it only costs $7. I think it took me 45 minutes to do it in my 88 silverado.

AND, All the oil must be drained from the compressor, AND 134A operates at a higher temp than earlier GM compressors are designed for, AND 134A requires a much larger condenser than allot of GM's have...

...134A isn't compatible with R12 oil like Freeze12 is, 134A needs the larger condenser to cool it down enough to cool you down enough and not bake the compressor too early...

...Freeze12 operates at a lower temp than even R12 so the compressor runs cooler and operates better as does the condenser, and is fully compatible with R12 oil. Freeze12 is as legal as

The guy here in town is gonna convert my 'Burban for $50 and I don't have to do a dang thing...

As I understand the r12 oil has a higher density so it sits in the bottom of the condensor and doesn't need to be evacuated. I guess I hadn't owned the truck long enough to see how it affected the compressor though.

runs cooler and operates better as does

as 134A and is about the same price.

I switched over a 92 when the coil went bad and it didn't quite cool as well as it did before all the freon leaked out.
