I recently changed out my waterpump. No big deal at all, and I still have a slight leak around the seal I think, but nothing to worry about. I've lost the coolant a couple of times but now its either stopped, or has become a very slow leak.
However, I recently noticed a flashing low coolant light that is invalid since the
bottle and radiator are full.
What might cause this, and where is the sensor for the coolant level located?
