I'm sure you guys get this alot, but I'm new here so forgive me!
Anyways, my 99 'shee has quite the overheating problem... it's bone stock, my anti-freeze level is fine, and I can't seem to figure out why, after not even an hour of being out in the trails when I stop a huge cloud of steam pours out of my radiator and antifreeze comes out the overflow. I'm no beginer so it's not like I'm going 5 mph through the trails (Not that the banshee's lack of low-end will allow that anyways) and I'm sure some of you have had this problem before. what can I do?

 

ride faster? maybe a metal impeler? when u get to a wide open space, spread you legs to let more air hit the motor and release some of the heat.

 

Buy a Raptor

 

I had a 99 shee, did the same thing on the trails. Has no cooling fan so speed was the only answer for me, I was constantly searching for open stretches to speed it up and cool it down. Topped the radiater off with river water lots of times. [img]i/expressions/face-icon-small-blush.gif[/img]

 

Speed, huh? CT trails are very narrow, rocky as hell, and there are no wide open stretches. I'm usually 2nd or 3rd gear. I've heard aftermarket heads do alot of good. I'm sure it wouldn't overheat on an MX track but there aren't any around here.

 

There is a coolant called "Engine Ice". Run this in your Shee and your problem will be solved. It has a lower surface tension than standard coolant so it removes more heat. It works great.

You can get this in Quad shops or search the net.

 

get a metal impeller

 

Overheating is caused by:
Lack of airflow past the radiator (bad fan or obstructed radiator).
Lack of circulation due to a pump problem or stuck thermostat.
Radiator pressure cap no longer holds pressure (3 degrees F per 1 psi)
Excessivly lean condition in the fuel system.
Exhaust restriction.
Lots of "enthusiam" in a very hot desert (really hot).

A head gasket blow-out will look like a boil-over when compression gets into the cooling system.

 

Banshee's are known to overheat when running slow, like when cruisn' thru the pits. Just put engine ice in and forget about it.

 

I think using the engine ice is a good idea but for this situation i think it might be like putting a band aid on a gunshot wound, Ive replaced that stock plastic impeller on more than 4 shee's ive worked on, a stock banshee cooling system works great as long as all the parts are working correctly, buy an impeller from one of the many manufactures out there, i would bet if you remove your clutch cover yours has melted the impeller or the bearing seals causing it to cease to rotate.
