like I stated before do not use sealers of any kind and adding pag 150 is the correct oil for THIS vehicle ....
it is better to be at a low charge than having too much r134 as the pressures will damage the compressor ,,,the compressor must never compress liquid refrigerent at any time or its over..

Thanks for the info. How do I install the pag 150 into the compressor?
