[img]i/expressions/face-icon-small-wink.gif[/img]Here is a strange problem I encountered and fixed in no time. I needed to change oil and couldn't get the crankcase oil drain plug out. I disconnected the external oil supply line and drained out the old oil and connected it back up. After that I got overheat warning red light while the radiator was cool. The problem turned out to be trapped air in the oil line which caused little oil to circulate into the radiator for cooling. After the air block worked its way out things worked ok. Next oil change I plan to use the crankcase drain plug!
