I have a 2009 LE with about 51 hrs and 450 miles. Two weeks ago I went mudding and I got in a hole that covered the radiator completely. I didn't notice until I heard the water boiling by the passenger floor. I pulled it back to camp and noticed all the coolant was gone, so I refilled it and washed the radiator and it ran good again. Last week while riding it the temp light began flashing but then would go off. Well last night it began to overheat again but I didn't see any water leaking, anyone have an idea on what the problem is?
