Engine Size: 2600
Refrigerant Type: R12
Country of Origin: United States
Can Freeze 12 refrigerant be added to a system that contains R12? Or does the system have to be evacuated and replaced entirely with Freeze 12?
My own 1988 Mazda pickup (B2200) I've kept R-12, glad I did.
I've had this truck since 1994. I wouldn't risk it with Freeze-12 if yours is a 2600i, especially if Cab Plus and low mileage. If so, sell it to me !!!
Anyway, what you're maybe more interested in is where I've encountered refrigeration leaks. Once I had to replace the evaporator, leaked in its middle (2002), used replacement from this board sponser. Once had to have high pressure hose re-welded and re-crimped, was leaking there. Once had "heat fuse" on the receiver-drier pop a crack, now it's plugged and my compressor (rebuilt, also from board sponser) has a high pressure relief valve, not "factory" on 1988 models.
A mixture of R-12 and R134a (Freeze 12 is R-134a based) is worse cooling performance than either one pure. If you're going to convert, remove any remaining R-12. Realize that it is still possible to buy R-12, and it works better in old cars than any substitute does.
Replace your fan clutch too, it's going to be shot after all the years. It takes a lot more airflow for good A/C performance than it does just to keep the engine from overheating.
Just where can you buy R12?
We get it from the dealerships. But as long as you have a certification there is many options. We have had issues getting small cans. So looks like 30 pounders from now until they run out.
Answers is YES to your "Can Freeze 12 refrigerant be added to a system that contains R12?"
But the consequences would be devastating, pressures would skyrocket and blow your system apart, dryer would dissolve and seize your compressor. You will have one heck of a mess on your hands.
Haven't seen this question in years, will give you credit for asking first. Its easy to add Freeze 12, and literally thousand came here, AFTER they added Freeze 12 to an R-12 system. In my opinion this company should be shot for the way they were advertising their product, that 12 has no business being used.
From all indications and from what I read, R-12 never did have any adverse effects on the ozone layer, even NASA backed down on this. Just a complete ripoff from our government where two succeeding administrations never reversed it. But we could still use it providing you wanted to pay the price. Practically every other country including our neighbors to the north permanently banned it.
Your car doesn't adapt very well to a complete R-134a conversion, condenser is the main culprit, plus you need all to change to all R-134a compatible components. Tim will know if he still offers a kit, least you get all new stuff and for about the price price as purchasing a 30# jug of R-12.
EPA wants your old vehicle off the road, that cash for clunkers was yet another program to accomplish this that resulted in huge price increases for used cars. Government bailed out GM so they can keep on screwing us. Puts the little guy in a very bad position. Then I hear a lot of our road tax dollars are going down to Milwaukee and Madison for public transportation that can't even break even, but they want them to take the bus instead of driving. We have no choice up here and gas going over 4 bucks a gallon doesn't help either.
But has no effect on the wealthy like those 400 families that own over half this country. What happened? We could afford a new car every two years for what we pay in taxes, just bend over an smile.
We have 125 undeclared wars in our history, all essentially failures, current president get involved in another with another one on the way. Don't believe they teach history at Harvard, just all legal stuff and how to work around it.
EPA has a history of solving one problem and creating five more in the process, so what is this stuff about learning?
