Recharge refrigerant 2007 Grand Caravan.

[Rickkins]

Hi guys.

So, the a/c in the old girl seems to be not as cold as it used to. Still cool, but less so than in years past.

My understanding, such as it is, is that my van has R134a as it's refrigerant.

Problem is, this is not longer available here in Canada. Instead, we have r12a, which is where the confusion comes in.

On the one hand, we're told that it is completely compatible with the r134a refrigerant.

On the other hand, we're told that mixing refrigerants is not allowed.

Now if this is just some silly government reg, I have no problem ignoring it and mixing away.

On the other hand, if it's gonna snokker my cooling system, not so much.

I guess mainly I wanna know if others have successfully mixed with good results.

I'll assume all replies are hypothetical, of course...

Thanks.

your misinformed on your information. they no longer make r12. they stopped using that in the early 90s. r134 is in all newer vehicles and every shop that does a/c uses it. I'm a mechanic in Canada so I know about this. you can't mix them. if you go into Canadian tire or napa, they sell cans of refrigerant that say something like r12 them, but that's just an aftermarket designation, you can use those to top up the r134 system. but its best to just take it to a shop that does a/c and get your a/c recharged.
