Ok, I'm about to go insane. I have an 08 brute 650 SRA, the temp light was coming on when I would ride trails, so I removed the radiator, cleaned it out really good and relocated it to the rack. I let it idle today until the fan came on then rode it around the neighborhood about 10-15 mph, and the freakin temp light came back on! When I parked it and the fan shut off you could hear to me what sounded like bubbles or bubbly noises in the radiator hose. Please help me figure out wtf is going on here because it is driving me nuts! Im running water and water wetter in the radiator as well. Here's a pic of the setup

Most likely the small auto reset breaker under the seat...P/N 21008-0001 BREAKER,FAN MOTOR.

I have had two of them go out. One on each of my 2009 750 Brutes and both had the same symptom you described.

I had this problem it would come on but shut off after a few seconds. I replaced the breaker under the seat with a 15 amp fuse and have had no problems since then.

i took the upper rad. hose off to burp it and nothing came out but air, then a little water. can hold it at a steady low throttle and a small trickle comes out, if you rev it up a bunch comes out then stops, then a little. its wierd

what does that breaker do? control the fan or what? My fan comes on like it should, Im just confused as hell as to what is causing this issue. It's keeping me from going riding haha and to say the least, pissing me off

The breaker controls the fan.

If you are not getting any water flow then I would check if the impellor is tore up in your water pump or the thermostat is froze up. Both take a little wrenching but they are about the only two items that can cause you not to get water flow.

The good news is that either of these items is pretty cheap to fix. Maybe 30-40 with a new gasket.

I just burped it and added quite a bit of water to it, and rode it for about 10 minutes in this heat 100 degrees at least, the fan came on pretty quick and stayed on the whole time. The light never came on this time. Im just nervous as hell to set out riding it. How can I tell if the thermostat is bad? The guy before me said he changed the coolant after break in. He only added 1 quart!!!!!!!!!! The bike now has 60 hrs on it, which I have only had for approximately 3 hrs! Since the fan is working I wouldnt think it could be the breaker under the seat?

Sounds more like a circulation problem. If you get all the air out and it still does it, may be thermostat. Pull it and place in cold water first and make sure its shut. If it isn't, its bad. If it is, then put some water in a pan on the stove and heat it to about 200. Use an oven thermometer to get it close. Drop the thermostat in and watch it. It should open about all the way which doesn't look like that much. If it does, its good, if not...well.

A lot of people use and like Engine Ice coolant. Seems to work pretty good.

I also hear that plain water with water-wetter doesn't raise the boiling point of the coolant. I don't know if that true or not but if that's true, then at 212 its will start to boil and when that happens, contact is lost between the coolant and the metal parts like the cylinder & heads. That makes it..well...not carry the heat away and overheat.

Sounds like a head gasket to me. If your fan is coming on it's not the breaker.

I had mine boil all the water out of mine

I burped it and filled her up. Rode it for about 30 minutes down the bayou and in the retention pond. The fan did stay on the whole time, but the temp light never came on... knock on wood. If it was a head gasket, it should be smoking out the tail pipe and have water in the oil......
