I have a coolant leak. It does not leak when the car is parked and it does not leak for the first several minutes once the car is started. However, once the engine is warm, it leaks pretty steadily. I can't get a good look at the source. What I do know is it is below the upper radiator hose (but I am 100% sure it is not the hose nor the hose connection) and above the bottom of the radiator. Somewhere in the middle. Does anybody have any ideas where the leak could be coming from? Or at least how to find the leak. Thanks so much.
