Question type: Maintenance & Repair

I have a coolant leak that seems to get really bad when I turn on my air conditioning heater.

Find the leak and fix it! The engine runs hotter when the AC is on which could make the leak worse. Check hoses, the radiator and the water pump.

Hopefully it's something simple, but, could be loose timing chain rubbing hole in cover, or worse yet, could be head gasket. Gotta figure out where it's coming from.
