My '74 is running a bit warm when I drive under 30mph if the

outside temp is 85 or more, but seems to be fine at higher

speed (or when temp is below 85). I am looking into an

electric fan (not that I know for sure that this is the problem,

but from what I have read seems possible???).

Sounds like a lot of people here have added the flex a lite

130, which I might try, but I'm wonderig why use a pusher in

front of the radiator - doesn't this block wind flow from

driving? Also, does the location in front mean that I should

run the FAL with my stock fan or can I disconnect the stock

fan (more power?)?? (sorry for the rambling post - a little


Thanks in advance for the advice!

in there... the stock cooling system *SHOULD* be adequate for a stock motor. even the 130hp tii uses the same little teeny 02 rad as the 100hp carb 02. to answer your question, the point of an electric fan is to eliminate the stock fan for quieter running and more available power. it probably takes about 5-10hp to spin the stock fan at 6000rpm (maybe), so for about $100 you get that little boost of available power. it wont block flow enough to counter the effects when the fan starts blowing. use a thermo switch set to about 180degrees, with a good stock rad (getting yours boiled is about $45, but i paid $18 for my good used 320i radiator). you might want to upgrade the stock alternator if you havent done so already. easy upgrades abound....

From what I've read, there's not enough room to put an elec fan in place of the stock fan.

Many use an elec fan in front as a supplement to the stock for city/traffic conditions, or AC.
