1990 Chevrolet Astro Q&A
1990 Chevrolet Astro Question: How do I release freeon from my compressor/holding tank?
The proper way to correct an a/c system overfill is to empty the a/c system completely and refill it with the proper amount of 134A. There is special equipment which should be used to remove the 134A you have in the system now. With the proper equipment you can remove what is in the system now and reuse the same 134A, putting back only the amount necessary to properly fill the system. - Russ
