I have a Mazda with 2.5L V6 engine.
I overheated the car so badly, it stalled as I was pulling into the parking space. Upon examination, I found out that it needed a gallon of radiator fluid and that it was leaking really badly from the water pump area. I also have a small leak from the radiator but nothing so bad, needed maybe a quart every two days. I don't think it's the cause of the overheating. Also, my temp. gauge does not work so I had no idea the temp. was that high.
Question, how much damage have I done?
I haven't driven it since then of course. I filled it up with water, run it for 5 minutes and did not see any coolant in oil or vice-versa nor did I hear any strange noises like before. (Worn out water pump? Or something inside the engine?) Tomorrow I should know if it smokes white, which is a sure sign of head gasket failure, which is my real concern.
