I know condenser and compressor are different between R12 and R134 system, but are the other parts different too ?
Thanks

 

pretty sure everything is the same between r12 and r134.. they just use r134 now cuz its better for te environment.. prelude climate control sucks anyways, never used my a/c in either prelude ive owned and i ended up removing it in both..

 

Nope, the condenser is different for sure, the piping too I think.
I got a Prelude R134 condenser and the location of the input and output are different.
The plug use to refill R134 is different from R12.
From wich year the prelude use R134 in case I have to order some parts.

 

OH yeah - know there are conversion kits from r12 to r134..........so, they're different. Otherwise, people would just refill. Make sure you don't let that **** out into the environment - if you do, its like a 10,000 + fine. And there's a reward if someone turns you in

 

its the same im pritty sure.
you need to get the r12 sucked out and get the r134 put in.
if the r12 and r134 mix it will mess up the lines because it turn into thick sludge.
