Exactly what formula of Refrigerant do you use to charge A/C on a 94 Accord?

 

Probably R134a, Honda switched from R12 in the early '90s. Either way, there's a sticker under the hood somewhere saying what it uses. Make sure you find this, because you don't want to put the wrong stuff in there.

 

94 accord i believe was switched to r134, mine used that. Buy a shop manual if you can, haynes is like $15-20, or go for the helms if you can. they show you step by step how to do it.

 

WalMart sells R134 conversion kits and also recharge kits

 

1994 and newer cars use R134a as the refrigerant.

I would take it to a shop have it leak tested and repaired if applicable
