where would you get the REAL benifits.. having a pulled fan or a pusher. ive herd pusher fans creat dead spots in the Rad. where no air flows threw. but at the same time ive herd that pullers do less becasue they have to pull there air threw the rad. soo wich is really the better way of mounting your fans?
i was tempted to mount 2 pusher fans along with the puller already on my car but was told that would creat turbulants and inturn flow less air.. tell me what you think...

 

well pullers work better, thats why cars with only one fan usually have just the puller. IMO the ultimate fan setup would be two aftermarket 14" fans pulling air and one smaller on in front of the radiator just in case.

 

Never mount an electric fan in Front of the radiator if you're already using a Puller fan because both fans will want to try to cancel each other out.

 

That is what i herd too... but i do plan on getting to doule fans soo you think i should mount them as pullers?

 

Definately mount the fans as Pullers. The electric motors run more efficiently that way and as a result the fans turn more rpm with less effort.

 

Go with the dual pullers!!!

 

Puller fans draw cool air in through the radiator and into the engine bay in the same direction it flows naturally due to the air dam setup. If you try to push the hot underhood air out through the radiator, it won't cool the coolant with the hot air, and your fans will be trying to blow air opposite to the direction it wants to enter and so there will be fery little flow in general through the rad. You'll probably be seeing overheating at slow and fast speeds, not just one or the other.

I think your miss understanding how the pusher fans work. They are on the out side of the radiator pushing the air through it into the engine bay, still the same direction of flow just that the fans are on the other side of the radiator.


Take a look at large trucks. They usualy have the primary puller fans, and a secondary pusher fan that kicks in under heavy cooling loads. The pusher is a smaller fan that is mounted off to one side so that it doesnt block the regular flow. So there is a way to use both but I would imagine that if you have dual pullers you should be fine.

 

I see now. Thank you for clearing that up. I learned something new today.

 

No Problem, anytime

I figure Ive learned tons of stuff here so I might as well give something back once and a while, lol

 

The pushers I've seen used are in a case where the stock clutch type fan can't keep up around town with the ac on. So, they install a pusher on the front of the radiator to 'assist' when the temps get high enough. I've also seen alot of them on pick-ups that pull heavy loads alot(big campers and such). I can't see much benefit if you already have a good puller(or pullers) that are electric. Yes, pullers are more efficient.
