Electric fan or Flex fan?

I used to have a flex fan that came off the water pump pulley that pulled air in and cooled the motor. But the fan was just so loud, could hear it almost over my engine. So i got an electric fan and took the flex off. Seems to be running fine. Temp is normal.

The flex fan pulled air in towards the motor but the electric pulls air away from the motor out the front of the car through the radiator.

Which do you all prefer a Flex fan or an electric? And pls tell your own opinions on upsides and downsides with both.................

Actually i have crossed wires, try'd different setups, checked all connectionbs. ran a shit ton of tests. The fan only goes one way. when driving the fan is off. Air flows in through the radiator and cools the engine. When sitting still or car is off. I can flick it on and let it run. Type of fan i have. I thought it was defective. but i called a few people and everyone said its normal.

Pusher? lol that would mean i would have to mount it in front of the radiator. Nah not made for that. i will call the dealer in the morning. But i still flex fan or electric haven't had any problem with cooling

my temp gauge----> C(NORMAL)H thats how it reads. Maybe 2 or 3 times have i ever seen it get between the r and m, no further. it usually sits on the line between c and n or on the n. But i haven't had it in the florida heat yet, that will be the real test of the new electric fan.

the stock temp gauge sucks, you can only tell if its cold or really really hot by it.

what kinda fan is it? my bet is that it is a pusher fan.

sucking hot air off the motor through the radiator isnt going to cool much of anything

an electric fan should either be mounted in front of the rad and push air into the rad or be mounted on the eng side and pull air into the rad. I've never seen a fan push it out the front of the car.

you got the wiring reversed, for it to work properly it should pull or push fresh air through the radiator towards the motor, unless you are planning on driving in reverse all the time?

Electric fans can come as pushers, pullers or both. If the fan is a pusher it needs to be mounted on the front side of the radiator. If the fan is a puller it needs to be mounted on the backside of the radiator. Some fans can be used as a pusher or a puller depending on how the wires are connected.

Either way, a good electric fan has no drawbacks beside the price.

If the electric motor operates in both directions.

the electric fan is safer,my friends was working on his car when the engine was running and one of the blades from the flex fan broke off and flew into his arm, and my old 4 banger stang had one of those solid factory type fans and a blade broke off when i was driving and dented the hood from underneith. I couldnt evern drive the car cause it was so unbalanced the motor was shaking till i replaced it. i guess we should start using fan shrouds

An engine driven fan can cast you around 10 or so h.p..
