    How many 12oz cans of R134a in a 73 RV2 system?

    I generally charge my vehicles a/c @1200 rpm, with r134a. suction pressure would be stable, no more than 35# (40 degrees), and not below 28# (about 33 degrees), i dont care about head pressure, as it will be high, as the vehicle is sitting still. vehicle physically moving, more air across...

    Heater core flows only in one direction

    somewhat related........... did my ram. royal pain the ***. if i wasn't so short on time (i think i'm part russian), i shoulda sliced an access port thru the firewall for both coils and patched with sheet metal. ram took me the better part of 2 days. i hate to think about doing one in my...

    AC charging

    hmmmm........... ranger's table, is operating, with the conditions shown, without taking rpm into consideration. an idle system pressure will not tell you if your are low, unless the vapor pressure is below saturated temp. the liquid will boil off, equalizing pressures to ambient. only if there...

    AC charging

    you should also be cognitive of how much the system should hold, and how much you are dumping in. plus, a non moving vehicle will run higher than normal pressures, because of lower air flow across the condenser your pressures are suspect, as is the no air flow. i have no idea how much gaaas is...

    AC charging

    r12? how many cans? no air across the coil, yet air out of the vent was 58? head pressure only 100? wagonman is correct on pressures, r12 and 134 are close i usually charge @ 1500-1800 rpm, with windows closed, back pressure above freezing, compressor not cycling
