The red light sensor with the arrow and ripples came on in my car Two days ago. I took it to orileys and thought i had low coolant but that wasnt the case. The guy noticed there was a leak coming from somewhere we couldnt find the leak. My boyfrind looked at it the next day and noticed ther was brownish.fulid leaking from the bottom. The car is not getting hot and its not getting low on coolant either wat could be causing this
