You have obviously found the leak that dumped the gas in the first place ,if not you have a wee job to do before you re charge the system .Not sure 134a is a good choose ,has a bit much pressure and you may have to change the T X valve if it isn't adjustable and change the oil for a Polyol Easter oil ,you most likely have Mineral oil now.Try ringing you local air con shop and ask for a suitable DROP IN replacement gas .I am a fridgy but I don't work on autos just shipping containers.If you can get the use of the tools you need I can talk you through it ok.Just a point for any one doing a change in gas ,you seldom use the same quantities of a new gas as the old .There is a formula for this .You will need a bottle of Nitrogen and a regulator for leak test ,may be about 200 psi .Big Blue or soapy water to find the leak.Make your repair ,test again .A vacuum pump to evacuate the system ,leave on for an hour or two .Then way in the correct volume of the new gas .You will need fridgy gauges and hoses to make your connections----- Hey you probably know all this anyway but give me a call off line if you have any problem I will know someone that knows more about auto air than I .Or may be this may prompt some one to comment .Regards Hoppy Message ----- From: <dardal@xxxxxxxxxxxxxxx> To: <mailing-list@xxxxxxxxxxxxxxxx> Cc: "Otis Davidson" <otisdavidson@xxxxxxxxxxx>; <mechimike@xxxxxxxxx> Sent: Friday, April 25, 2003 3:52 PM Subject: IML: 68, R134 conversion > I am sure this has come up before. > > My 68 Lebaron used to run Freeze 12.
