Fan- Blowing air or Sucking air?

[quennc]

Ok, now i'm a little confused here. I just read on another website that the fan should be sucking the air from the front of the bike sending it to the rear. Is this correct? I always thought that it should be blowing through the rad towardds the front of the bike. Which is what mine is doing.
Hope this is alright but i posted the link just so you can all see this. Scroll about half way down. He mentions about using a peice of paper to test it and it sticks to the rad. And i noticed noone really commented on this. So if this is right then i think i might have solved my heating problem, i hope!

that is the way it is supposed to work//// pulls air across the radiator.. that is a test that can be used place a pice of paper in front of radiator it should be sucked to the radiator..... In cars in the winter the paper or cardboard can be used ti partialy block the airflow to increase temps to make heater preform better (Old guy stuff Like pliers baling wire and duct tape) :Egyptian: :Egyptian:

Yes. The fan should blow toward the rear of the bike drawing (sucking) air through the radiator. If wired backwards the fan blade is inefficient and the air stalls while riding. Causing it to overheat while moving.

Fan blades are designed to move air in only one direction, looks like you may have found your problem.

Ya...should be pulling air from the front to rear. :good:
An electric fan running backwards will eventually burn up, since the air pushing thru the rad is going against the fan, which is trying to shove the air back out the same way it came in. :mrgreen:

Lets hope its that simple.
If it running backward then someone had to change the wiring connections to the fan since all wire plugs are designed to plug in only one way.
Look for splices and suspicious tape starting from the fan.

Just went outside to test this fan and sure enough, i go and put the peice of paper in front of the rad and it's pushing it away. So i'm guessing the fan is suppose to be going counterclockwise.
There are 2 little wires which look like the fan connector behind the fan. I remember notice how they could easily be put on in reverse.

The connector on the fan is rubber and should have two wires going to it, but the plug should only go on one way. Follow the wires back, the must have been cut and rerouted at some point.

If it can be plugged in reverse then the plug has been changed. The original is polarized to prevent reversed polarity and wrong rotation.
I'd be looking for other hacks in the wire harness possibly causing the temp gauge to read high?

 

[quennc]

there's no rubber connector on mine. The only rubber connector is to the switch next to the tstat. The actual connector were 2 little wires with flat ends on them. I had a hell of a time putting them each in there own little grove. Knew that there was something wrong with that connector when i removed the fan with the rad. So just so i know Dan, the fan is suppose to be going counterclockwise?

 

[dan filipi]

The connectors have been changed.

Looking at the front of the fan it should rotate clockwise.

 

[quennc]

If i'm looking from the front of the bike towards the rear the fan is going counterclockwise. Great, atleast now i know where my problem lies. Now to trace the wire.

 

[quennc]

Unbeleivable. Never thought i would ever see the temp gauge go down. Reversed the wires, fan was turning in proper derection, got the bike to just above half on temp gauge and wouldn't you know, the temp gauge started to go down once i turn the fan on. Success finally!!!!!
Want to thank everyone for their advise. Was getting really worried about having to replace the head gasket and all along it was the fan turning the wrong way. Stupid simple little thing that i would have never thought of if it wasn't for these sites and took a whole 2 min. to fix.
Going for a nice cruise now,

Later, and thanks again.

:yahoo: it's great when the fix is simple! :smilie_happy: arty:

 

[dan filipi]

Great, I'm glad it was simple!

I would have thought at a standstill running even with the fan running reverse there would be enough airflow over the radiator to bring the temp down. Guess the blades themselves and maybe rotation speed are not enough to move enough air.

Never stop learning I guess.

Nice! you will now need to send a payment of $200 to the site's PayPal account. :whistling:

You would think, eh? The problem is most likely because, with the fan running backerds, it has to draw air from around the engine/shroud, and push it thru a smaller area of the radiator, whereas with it running properly, it draws air from the outside, thru the entire surface of the radiator, with help from the shroud. The shape of the blades will also have an effect.
That's my theory, and I'm stickin wid it... :blush:

You learnt 2 valuable things.
1. Always ask questions when in doubt.
2. Start with the simple and cheap, and work your way up the $$ chain
