Guide :2010 GMC Terrain : My car is overheating
My car is overheating - 2010 GMC Terrain
My GMC terrain is over heating, replaced the thermostat and it's still overheats. So after it over heated I felt the coolant hoses and all were hot except one, the one going from the radiator to the thermostat housing, or the lower. My question is what are possible causes for my terrain overheating? I also noticed leakage from under the overflow reservoir.
