I bought an electric fan from a late model Ford Taurus at the local Pic-in-Pull for $40.00.

I bought a new two-stage relay for about $100.00. All I had to do to the fan was trim about a half inch off the plastic housing in order to mount it to the radiator.

The relay kicks on just past the 3/4 celsius mark (how come that isn't noted as 180 degrees fahrenheit?!) and in about three minutes pulls the temp back down to the 70 degree celsius mark, and shuts off about 160F. And this is while idleling!

I don't know what the CFM rating is for the Taurus fan, but it is about 400% better than the stock Lucas fan that came on the car.

That Lucas fan couldn't pull enough air to blow out the candles on a two-year old's birthday cake!
Since installing the fan, the ol' cat has been all over northern California in 100+ degree weather, and has not had an overheating event in heavy traffic or running at 80mph* on I-5.

The best part is getting waves and positive comments from some of the other drivers out there.
I heartily recommend using these fans for solving a heating problem, provided you have a decent radiator.
