Took me 8 hours to find a coolant leak that was just a loose clamp under the airbox
I was pulling my hair out on a 2015 Renegade 1000. Temp gauge climbing, puking antifreeze everywhere after 10 minutes of riding. I pressure tested, replaced the cap, checked hoses, even pulled the radiator. Turned out the lower hose clamp on the thermostat housing was barely loose. You could see the crusty residue if you bent the hose a certain way. A 10mm wrench fixed it in 30 seconds. Has anyone else wasted a whole day chasing something this dumb?
