Q: Coolant leak

asked by on

Coolant leaking from somewhere. cant find the exact location but it seems to be about where the oil drain would be. about right in the center under the hood.filled coolant reservoir half way between min/max line let sit overnight now its under min line again

My car has 134000 miles.
My car has an automatic transmission.

You would need to have the cooling system pressure tested to verify the leak but I would have to say it is most likely the heater core leaking.
