[DML] Re: Bob's AC problems.

["Jim Reeve" <dmc6960@xxxxxxxxx>]

Bob, everyone keeps asking you this but you never answer it.  What are
your HIGH and LOW pressures!?!?!?

You blew a high pressure hose, probably because the high pressure was
too high.

Your engine heats up with the AC on?  Simple reason...  Have you ever
felt the high pressure hose leaving the compressor?  Its HOT!!!  This
hot gas is going into the condensor which is in FRONT of your
radiator.  When your AC is on you have much hotter air travelling
through your radiator and thus is has less cooling capacity.  The
higher the pressure, the higher the temperature of the condensor. 
Your probably running so high that the condensor is heating the air to
220.  And if the air going through the radiator is 220, thats the
coldest your engine can get.

You say your friend replaced the high pressure hose and replaced the
R12.  How much R12 did he put in there?  What method did he use to
fill?  Was the whole system completely vaccumed down before hand?  Was
the system flushed?  What were the pressure readings after everything
was done?

Other posts mentioning a possible blockage are probably correct. 
Either that or too much R12 in the system.  The pressures are where
you must start though.  Give us those readings.
