Soooo I changed the coolant in my 2007 rhino 660 and it looked like muddy water so I thought it would help with my issue of overheating. But after letting my bike idle for 10 min and re check the coolant level the rad was still getting hot. Sooo I'm checking different things and I get near the oil coolant lines and I can feel the heat coming off of it and you can't hardly touch it before burning yourself. Is there a way for me to check if the line is clogged or what should I do to fix the problem??
