Hey guys....can you tell me what kind of refrigerant would be in my 2005 Blazer....this is the original refrigerant....I't still keeps things fairly cold inside.. but I know it should be better... im thinking of buying one of the Red Tek 12a kits....and recharging the system....is this a simple job or should I not mess with it at all.

Thanks for any help.

 

R134a is what came in it from the factory.

 

Thanks for your quick responce swartlkk...is this a fairly simple job using one of the kits to swap out the R134a for the 12a.

 

If your not aware of what's in it I doubt you have the stuff and know how to remove it and get new stuff in. More too it than simply plugging a hose in.


Why do you think you want to fill the system with propane (r12a). Its illegal to retrofit in r12 systems for a reason. Since r12 isn't being produced its hard to get and costly. All cars since sometime in the 1990s use r134a and since it won't blow up in a crash legal to retrofit into a r12 system.

 

This is why im asking questions here.

 

No it is not a simple process nor one that you would be equiped to do in your driveway. It isn't really a suggested swap either.

You may just need to top off your system which is something that can be done in your driveway with a R134a recharge kit from Wal-mart or just about any autoparts store.

 

See the edit above, I had to look up what r12a was. Basically unless you have a deathwish leave the propane for you grill. Even then imho its a bad choice.

 

I have seen it used propane in the old R12 a/c systems on tractors before but that was when I was VERY young. Once the conversion kits became cheaper, we eventually changed our tractors over to R134a. Propane is actually a VERY good refrigerant. It just happens to be a very good fuel source as well which is why it isn't a good idea.

 

Didn't say it was always bad. How many john deeres do you see in a crowded freeway doing 70mph. I also cant argue about the fuel rail but its normally not hanging off the front of the truck and always gets a hole in it during a wreck. Fuel lines are also normally not placed beside a battery in the front of the engine bay.

Being a fellow FF you know as well what always get bent and is leaking in front end wrecks. Having to worry about an ac system full of propane isn't the first thing that runs in your mind unless its on a placard.

 

I'm not advocating the use in automobiles by any stretch, especially given the safe alternatives that are available for those systems.
