[Shotimes] GEN II AC ... Can it Handle the Heat?

[Ron Porter]

Gen 1-2 folks may want to consider the serious problem that plagues Gen 3
owners (and killed Larry Eck's engine).

He had a serious buildup of cottonwood fuzzballs that built up on the
radiator, between the radiator and the condenser. Might just want to check
to make sure that the area is clean, and not obstructing airflow.

I think the condensors are one of the pitfalls of a car this old, at
least is is on my 93.  The problem is that the things get packed full
of bugs, debis and then the fins get bent and mashed and mangled.  I
spen a couple hours cleaning mine, but I am still under the impression
that it is jammed full of gook.  I think I was able to get the stuff
off the surface, but there is probably a lot crammed so far deep into
the fins I can't comb it out.

Even with a bigger radiator, I tend to run a bit hotter that other
SHOs around (like at the convention I was seeing water temps 10-20
degrees warmer than others).  It did ok, and stayed on the autometer
gauge, but probably got into the 235-240 degree range coming off the
track.  Some of the laps though when caught behing traffic I would
turn the A/C on for a break for me!  Big help in the late afternoon.

So I think, at least for me, is I have a condensor that is not letting
much air pass through, not cooling the condensor well, and not letting
enough air through to the radiator.
