my 87 300d ac has been getting warmer of late and i wanted to top up the freon. i have a bunch of r12 cans and the hose to charge the system but on the cans it has instructions to hold the can one way to charge liquid and upside down to charge gas. which way should i be using the r12? also i don't have gauges to check pressure...i have never messed with ac stuff before but i know there are some w/ much exp. should i try this myself of take it to a shop?
