- Aug 17, 2007exactly, i always was conscious of temp, and sometimes that was a bit
annoying to worry about it,but that should probably be done even if the main
fan is left intact anyway

I didn't mean to suggest that the electric setup wouldn't work. Quite
the contrary, I believe it would work well. Non-A/C euro cars were sold
by the thousands with only the electric fans.
The problem with the use of the electric fans in that era cars was that
a loss of the fan wasn't immediately detectable by the driver, nor the
ECU. The ECU would happily continue to feed fuel and spark to the engine
if it were melting. The driver's first indication of the fan failure was
generally a high water temp situation, which required monitoring of that
water temp gauge. If that failed, or if the driver had his sunglasses
on, was inattentive, or tried to get home before it got hotter . . .
I left my 6er idling outside my apartment to keep it cool one afternoon
with a failed aux fan and cracked the head.
