Over heating -- followup and question

[David Brady]

Hi Leroy, there's no doubt that the condenser and oil
cooler would radiate heat better if they were black, but
I probably wouldn't paint them black for a couple of
reasons: 1) they are probably performing their job
adequately the way they are, and 2) they look stock and
original the way they are. Maybe the manufacturers didn't
paint them because they didn't want to spend the
money on paint, or maybe manufacturing was quicker
without paint, or maybe painting ran the risk of closing
off important air passage ways. In any case, I'd leave these
items in their stock condition. Just my humble opinion.
