Put a new turbo section on my apex (alpine kit). Took it out for a test run. Sleds runs good. Rode it for 30 km then the temp light came on. Shut it off. Checked heat exchangers ( stock tunnel). Right side warm. Left side not as warm.The hoses going into aux rad considerably warmer than the exchanger. After 5 minutes started it , light was off. Drove it 5 minutes more , put it on the trailer, no light. Checked coolant this am , added a small amount to catch can, main tank right full. Took it out for another spin , 5 km the light is on. Shut it off for 5 minutes , light out head back home. Light on again , wait 5, light out. Drove it the km to the shop no light. I am thinking I don't have the cooling system bled properly?? Checked around the head looking for leaks. None I could see. Any thoughts? If it is a bleeding issue what is the proper procedure to bleed the cooling system?
