I am looking at replacing the fan on the back of my polaris's radiator and solving the overheating issue. So...

Looking for a good 12 fan (about 10" x 10")...

Who's had good luck finding a powerful one, one that actually comes close to performing like they claim (high cfm rating).

 

find one off a street bike or similar. automotive fan may draw too much current for the electrical system and cause more than an overheating issue. find a motorcycle junk yard or online and get a fan off of a CBR600 or similar bike. should be good to go

 

I have dual Procomp 16 inch S blade fans on my truck and they move a lot of air.

This small 10-inch draws 4.5 amps. @ 12 volts.

A motorcycle junkyard is a good idea.

You think 4.5 amps is too much to be drawing for the cooling fan?

 

How big is the charging system? It will have to produce enough current to have the fan and the headlamps running or you would be constantly discharging your battery.

 

Are you sure the fan is the cause of the problem??
It could be a thermostat, plugged radiator, leaking head, bad temp sensor, bad fan relay or maybe even some other fairly minor problem.

 

Positive.... Took the fan out connected it directly to 12v source.... nothing...

I think I'll run a small 10" fan directly mounted on the radiator...

Thoughts?

 

Just make sure it don't draw more current than the charging system can supply.
I assume that an ATV is like a bike and has almost no charging system output to spare and nearly zero output at idle.
(Many bikes have low wattage headlamps and will not support a standard 55/65 watt headlamp for example.)
