well after 85,000 miles the factory clutch fan has worn clutches. instead of electric fans or replacing the clutch fan($150) i wanted to try a flex fan. it didnt go too well. the rx water pump nub is too big for the center alignment nub, so i reamed the flex fan's hole out. got it modified with a longer waterpump shaft, so the flex fan wouldnt interfere with anything on the engine. finally got it all working properly. by the way it soulds so awsome at 7 grand. one slight problem, FRICKIN HOOD INTERFERANCE!! so should i just put on e-fans like evryone else, or cut the hood braces for clearance. the latter also means that i have to modify the fan shroud.
what do you guys think?

 

I use a flex fan, yeah the damn conversion was painful ( lots of lost blood) but it does sound awesome at high Rpms, But it doesn't cool it good enough so I have a back up e-fan

 

did you try uding a 15 inch fan?

 

no, this is an 18 incher. im thinking of going smaller though.

 

Flex fans are terribly inefficient compared to a thermoclutch fan. If you can't get a replacement clutch (Mazda or aftermarket), go electric. Just make sure you do it properly.

 

He's right the thermo fan is the best for the car, but the E- fan alone just didn't cut it for my engine so I am forced to use both, this is just one case though.
and use a 15 inch fan, maybe a 16 will work but I guarantee that 15 inches works if you go through with it.

I don't recommend using a clutch fan though.

 

The stock clutch fan (obviously with a healthy clutch) cools the engine perfectly. It's highly recommended.

 

I meant thermoclutch vs. the flex clutch fan, of course the thermo is better.

 

Ah, I see.
