Want to do some investigation on my Omega air con system. Any experts out there:?
1/ What's in the Schrader valve charging points with respect to springs and seals etc., and where can I get connectors to fit the valves to couple vacuum pumps etc.2/ How do I use the valve to first vacuum pump the system and then input gases.
3/ Does Butane do any harm to seals etc., in the system if it is purged before running.4/ Does it do any harm to pressurise both low and high pressure sides of the system with nitrogen at 200 psi say, for leak detection purposes.
5/ Where can I buy refrigerant in the UK., it seems there are plenty of DIY suppliers in the States but not here.Please note that the car is old, I have spent a fortune allowing others to NOT solve my problems, and I want to make a last ditch attempt to do this. Win or lose!!!
