i bought an electric fan from the local auto parts and a thermal switch to regulate it but once the fan comes on it can never cool it enough to turn it off even on idle, also if i drive it hard it will heat up above halfway and only come down after a while, i saw ford Taurus fans were good and also mr2 fans, this sounds like the fan i have isn't sufficient enough to you?

for those who have experience i was wondering which fan is best for my 12a

 

Tagging along here, I'd like to get an E-fan for my rex soon. did ya notice a power gain? Also, what year taurus are we talking here? I hear that it is the 3.8L 6cyl fan that is the best.

 

Yes. 3.8 fan from a early/mid 90s taurus. I have mine ran through a switch in the cabin so I can turn it on and off when I please.

I noticed a big improvement in first and second gear. Basically like adding a lightweight flywheel to the front of the engine.

 

I used a switch from inside the car, and turned my efan on as necessary. As for never turning your fan off, once I got going I never really turned mine off either. It regulated heat at decent temperatures, and I didn't "feel" a big difference with it on or off, so I just left it on.

 

Alright, So like a 90-94? I have a 94 Tempo with a 2.3 (my winter car) and I know thats the last year for that body style. Are they dual speed fans?

What are those small fans you see, like two small 12" fans? What are they from, MR2s?

 

Kentetsu added a set of fans from a 1st gen MR2. He said even with one they worked very well. They are designed to suck alot of heat from a cramped engine bay wtih poor airflow, so they should be more than enough for your engine. Plus, Toyota reliability. https://www.rx7club.com/showthread.p...light=MR2+fans
