 The vehicle began overheating. the check engine light appeared. it was taken to the dealer and said that the coolant became muddy and that happens a lot when the coolant gets a little low. the thermostat was replaced along with a flush and fill on the radiator and cooling system. the dealer wanted to put the same coolant in the radiator and this was unusual to me. i had them put in preston and had no problems since. *la
