Thanks Tom, tis is the correct way to go, but before refilling it I'd like to replace suspicious parts first. I can't have it refilled around the corner, locally they only refill R134 systems. There are two pressure sensors near the dryer that have O-Rings on them and can be replaced quickly. In 2002 I had them replaced with new O-Rings, maybe they can handle only R134 ? Are these O-Rings known problem parts ? Or do the system leak at the compressor ? Or the 8 meter 27 year old hoses ? Any experiences someone ? Thanks, Elvis > To find the leak you can add UV dye. ------------------------------------ To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnewsYahoo!
