Re: [DML] Vacuum leak solved...

Hopefully moderator will let this post through (answers specific
question):

Car had been sitting in the sun all afternoon -- was probably well
above 100 in there. Didn't leave the driveway because car blocked in
and electric fans start refrigeration cycle OK by themselves (engine
fans on my Lincolns can't do it sitting still). Checked temp on
previous charge about 2 weeks ago -- 42.9 degrees. Not as cold as the
Lincolns, but it is a different system. Will drive DeLo to work
Wednesday and recheck.

Interesting note -- last summer bypassed leaking heater core on my Two
Tone Lincoln. A/C evaporator started icing up like old freezer coils
(don't tell me R134 doesn't get cold!). Would stop air flow completely
within 10-15 minutes. Spent whole trip to/from DC alternating between
A/C and outside vent (to defrost evaporator). Also ended up with glove
box full of water. Guess Lincolns need residual heat from heater core
(don't have an accumulator and orifice tube -- use something called
"throttle suctioning valve". Has to do with Automatic Temperature
Control). Is same charge felt by people who went to Dave Swingle's
South Carolina Door Seminar in March BTW, so obviously new heater core
did the trick.

'Nuff said Re: A/C.
