hi If your going to use compressed air , use whats called an air drying desiccant snake commonly used by spray painters to treat there air supply . Made by Devilbiss . Google it . Use Shell X55 white spirit solvent . Very mild degreaser and cleaner . Will completely evaporate. The dispensing tool wo...

hi
The procedures on how to charge and Charging limitations guide has been mentioned

hi Done many 2nd condenser in series connection . Design of first factory condenser can be bigger or but usually smaller than the aftermarket second unit thats installed . Combinations of tube/fin and serpentine and parallel flow take your pick they all work in series . Common pressures on high side...

hi 1st vacuum pump change oil test pump and check to see if it can reach 29 inHg 2nd check gauges are not leaking internally --replace sealing washers and tap o rings ---install new manifold seals ---install new hose rubbers Vacuum system for 45 mins to 1 hr Vacuum leak test 15mins Charge with gas/l...

hi Little content about the idle cut out or idle up in a few of the previous posts . Although the conversation on pulley ratios is interesting and an associated subject sure but still unrelated . RE modern car cut out , these are typically ECU controlled not what the topic is about . Once again any ...

Yes u need to check gauges as these can leak by not completely turning ""off"" eg valve seating . Another issue canbe hose sealing etc at connections .

hi If u can get your aircon to work better when garden hose water is applied to condenser you have a condensing problem = not big enough ***Remember industrial R12/R134a systems DONOT run the high automotive pressures ****Automotive pressures on R12 in the sixties and seventies ran lower than 180-20...
