Summer is here and the good old R12 has leaked out. Does anyone make a kit to convert my '90 Accord A/C to the new refrigerant?

there is a forum here that has lots of info for conversions. If you want to convert to 134a, the least you'll need to do is, flush out old oil, replace 'O'rings, replace dryer. Then you can vacum the system, add pag oil, then new freon.
The 134a is a smaller molecule and will leak quicker than R-12, so I'd recommend a flourescent dye be added to the oil. You can use the old expansion valve but expect about a 10 degree loss.
Best of luck I hope this helps you.

 

you looking at a bill at least(if everything is cool)

but if you wanna stick to the R12 little longer

GREAT price

 

Freeze 12 seems almost too good to be true.
Thanks for the link and I will give this a try. I may have a small leak but if I can get the A/C to work for the summer it is worth the money.
