Ive been having some cooling issues lately. Just the other day I was driving and out of no where the ‘Low Coolant’ light went on. When I got to where I was going I popped the hood and noticed coolant everywhere. I noticed a gash in the upper radiator hose which may have been caused when I hit a bump and it rubbed against one of the pulleys. Anyway I replaced the hose, added more fluids and everything was fine. Now, two later the Low Coolant light is back on, this time I check under the hood and the radiator fluid tank is super low but their isnt any coolant leaking under the car or any visible signs on the engine. I noticed I havent seen the cooling fan running and thought that maybe so much heat is being generated that the radiator is sucking up coolant fast. Is that possible? How do I know if its actually the fan or could it be something else?
