'Replaced leaking exp valve coupla days ago. Filled with R-12; that doesn't
necessarily mean it hasn't leaked again, but no bubbles in sight glass
today, and compressor running now and BLOWING VERY COLD after sitting for
hour or so. 'Also considering KLIMA.
Also wondering about relationship to engine/coolant temp.

runner-up.
