As for the A/C, I've thought about just adding more R-12 to keep it
cooling
hopefully, for another few years (and running with 1 of 2 aux fans) OR
see
if the fan can be replaced without removing the evaporator.
Obviously, if
the evap needs to come out, (to R/R the fan) then I guess we'll check
and
fix any significant leaks and re-charge the system.
Hydrocarbon refrigerants also work well.
I've found R-12 12-oz cans for sale on CL. Anyone know how much I'd
need?
A "friend" with the proper tools is going to help me with this, as I've
never done A/C work before.
Should be on a sticker on the radiator support. 2.6#? But how much
_you_ need to top off an undercharge is best determined with a gauge
set, and a conservative mindset. If actually using R12 you could charge
until the sight glass was clear, while monitoring the gauges as a
fail-safe.
Don't convert to R134a.
