cant find ac - question about ac system

[dalinxz]

ok well i cant find anything when searching for a/c or ac so i want to know; recently i bought an 88 honda accord dx now im not sure whether it uses r12 or r134a or whether the conversion has already been done or not?

[EricW]

probably still r12

[dalinxz]

well i need a definite answer because i looked at my aunts 89 accord and it looks a bit smaller with a bolt with a black cap and mines an 88 and has a blue cap and is a bit taller, let me get a pic brb

I hope it was changed and has no leaks.

It has been converted to r-134a.

[lamontlamont]

best thing to do is just evacuate all the freon and replace with r34a to be on the safe side, will only cost about an additional 8 dollars to add an additional can of r134a, so its kind of stupid not to do that, you can do this all your self, just make sure you add the oil or better yet add the can of freon already mixed with oil.

ok to be honest i didnt know anything about cars until the 3gee, my uncle being a retired mechanic has been teaching me so far i can do alot with the suspension and steering but as for engine not so much and as for ac even less. Anyone care to explain. Also how do you know its been converted I was reading and it says that if it twists on thats R12 if not then its R134a the cap is a blue cap that twists off. its a threaded silver fitting

The pieces that you see in the top of the picture thread onto the old r12 connections. The r12 connections are closer to the size of a tire valve stem and resemble them to since they are threaded. The r134a is threaded on the inside for the cap but uses a quick connect on the out side for the r134a connections.

Yes to everything you said. I agree it has been converted to R`134A

If It Is Threaded Then It Might Still Be R12, Perhaps A New Hose Was Installed For Some Reason. My Advice Is , Dont Use The Adapter, They Always Leak, Just Get An Old R12 Cable For The Car Side, A R134a Cable For The Freon Can And Splice The Two Hoses Together, Thats What I Do. I Do This Because It Wont Leak And Those Adapters Suck. If It Contains R12 And You Add R134athinking That It Was Already Converted You Will Mess Up The Ac So Like I Said, Just Empty Out The R12 And When It Is Empty Add The R134a/oil Combo Cans Until The Ac Blows Cold Air. To Convert You Dont Need To Change O Rings, I Did My Change Over With Out New O Rings And Never Had A Problem, It Just Leaks Out Over The Winter But I Just Add A Can In The Spring And Im Fine For Another Year.

Take My Advice , Better To Splice Cables Than Use The Adapter. For This Reason It Is Also Possible That Even Though Its A Threaded R12 Fitting It Could Still Have Been Converted To R134a As I Did. ASIDE FROM FINDING A LABEL SAYING IT WAS CONVERTED UNDER THE HOOD OR HAVING THE FREON ANALIZED YOU CANT TELL WHAT TYPE OF FREON YOU HAVE SO BETTER SAFE THAN SORRY.

Ya the quick connects without thread is a good indication of R134. The only way to really tell is to hook up an indicator before the evaporator after the compressor.

your right no threads on the outside theyre inside yay im happy now i can recharge just need some bottles or a recharge kit
