(If I'm really losing fluid I'm worryied that it might be another head gasket problem. My first was a warped head caused an overheat after a water pump failure.)
My question is this: Does the sensor usually fail in the OFF position (such that it won't tell you when the fluid is low)? Or will it fail in the ON position (such that it tells you you're low when you're not)?
