93 A/C retrofit and recharge

[Sedito]

I am about to use a kit I bought to recharge the a/c system in my sister's celica. The kit says to recharge the system with the r134a to 85% of maximum capacity, but I don't know what the maximum capacity is for the car. I checked the owner's manual and the chilton, but neither has any information on it. Does anyone know what the capacity is?

The capacity for the system when using R12 was 25.4 +/- 1/8 oz.

Please make sure that you flush the system if the compressor failed, and if not make sure to use ester oil, that is what Toyota dealers use. After that make sure that you replace the expansion valve and the drier or you will just be back where you were. Once you did that, make sure to Vacuum down the system for at least 30 minutes, longer is better. Then recharge the system with the R-134 with the dye in it for leak detection. I would go ahead and replace the schrader valve on the high side for sure. It is old enough to fail.
