AN ELECTIRC FAN KILLED MY MOTOR!
Take this however you wish. I'm against the electric fan mod. I had a BRAND NEW Flex-A-Lite Black Magic fan installed in my 86. One summer day in traffic I noticed the temp gauge rising. I turned down the radio to listen for the fan and it was not running. I pulled over and popped the hood...
The thermo-switch that is built into the black magic fan failed. By the time that I found out, it was too late. The fan was 4 months old.
so the end result was:
$180 dollar fan = $2200 dollars for a new engine

This thread is over. Any longer and the misinformation just grows and grows and grows. E-fans have been covered before. NZ, Icemark and I have posted many times in these threads, with lots of explanation.

Actually before this thread dies a well deserving death, I wanted to mention and update to this thought.
On the 92+ Lexus SC/Toyota Soarer, the Fan system is probably the best of all types. Although the engine is most certainly a Longitudal mounted engine, the fan is actually driven by the power steering pump and fluid, rather than attached directly to the engine or using an electrical version.
This allows Toyota/Lexus engineers to use a viscous fluid clutch to properly activate based on radiator through air temp, as well as when the power steering is active (sub-45 MPH speeds) the fan is also driven by the increased fluid pressure and transfer of the power steering system. The fan of course free wheels at above 45 MPH when the power steering boost is removed entirely. Since the Lexus power steering system is almost identical to the S4 and T2 S5 power steering systems. The only time the fan is on is when the temp requires & the car is under 45 MPH. Basically only when needed, minimizing the drain on the power of the car in any form, electrical or mechanical.
I now return this thread back to its previously closed position.

Look under the bonnet of any full-size car with a longitudinally mounted engine (Merc, BMW, Lexus, etc) and you'll most probably see an engine-driven thermoclutch fan, with a supplementary electric pusher fan for the A/C, just like the FC.
