I was riding my SRX 700 mountain and it was running fine all day. Then as night came it started to overheat. I would stop let it cool down add anti freeze then ride for a bit and it would do it again. The light would just flash until I shut it down and all overflow would be completely empty it took a good liter to fill after it over heated. After I let it sit for a good 3 or 4 hours I went to load it on the trailer and the temp light flashed 3 times then stopped. It has never done this before. Does anyone know why it would be continuously overheating and what the flashing light means?

Got air in the system? Have you bled it correctly lately? Got a leak somewhere? Lots of variables.

Sounds like you have a leak or your head gasket is going and you are burning it. Or last time you drained it you didn't bleed it. Need some more info about whats going on to help. DETAILS!!! On start up your temp light should flash 3 times to tell you that the light works and so the cdi tells you everything is in running order.

check your power valves you may have pulled one through. how many times is the light flashing?
Do you run studs on the track? Might have thrown a stud into the heat exchanger and youre losing coolant that way
When it was over heating the light would flash quite a few times I would say at least 5-7 but I would shut it down right away though and didn't pay much attention to the amount of flashes at that time. I don't have a studded track so that should be a problem. The engine was rebuilt last summer so the head gasket should be good since it was rebuilt from top to bottom. There are no leaks anywhere other then some oil leaks from around the power valves but nothing major. Had someone say it might be the thermostat or coolant cap? is this possible?
Can you estimate how much coolant you put into the sled after it started over heating ?
I know you said it would take about a litre to fill it again after you shut it down because of heat but you didn't say how many times it over heated.
I ask because obviously if you have added more coolant, or even close to, what the thing will take if bone dry then you have a leak. Then again, if you have a leak you would most likly see the green stuff on the ground, right ?
Studs are not a prerequisit for getting a puncture in a heat exchanger, specailly if you are running in deep snow where hard things could get burried jsut below surface. I would think it rather unlucky to puncture an exchanger as you are not running studs but.. could happen. check it out. could even be the hoses running to the exchangers.
Thermostat can cause over heat but not coolant loss. The cap can cause overheat too but I don't think it will cause coolant loss unless it is not tight on the bottle.
Coolant loss can be caused by burning, leaking or evaporation. Evaporation would mean that the cooling system is open to the atmosphere though.
