any ideas my friend has a katurbo 9 psi and it just started overheating we bled the cooling system for air bubles and it wont over heat until you drive it for a while then the temp slowly rises until its overheating
i think the thermostat is stuck (half open) you guys have any ideas

Might be a blown headgasket. Do a compression/leakdown test.

could be letting air in somewhere? does his overflow tank pressurize ? like you see more coolant then there should be over and over?


does it overheat immediately after a hard run and not come down?

is it a new thermostat?

yea it over flows into the overflow tank the tank is open (not pressurized) once it over heats it does not come down just slowly keeps rising no matter how you drive it
