Ok, I have a slight coolant leak that only shows up after the car has been parked a couple of days and it is stone cold. Nothing leaks when the car is running and hot. The drip comes from the front of the car somewhere- can't find evidence of leaking at any hose connections, my waterpump was replaced 4k ago last year, and I'm stumped. Any ideas of what would cause a leak to start only after the car has been sitting for awhile?
Cold, low pressure coolant leak

I'd guess that it is also leaking when hot. But the leak may be small enough that the fluid evaporates off the hot engine. Basically any of the cooling system components on the front of the engine are suspects. If you can't spot the leak, have the cooling system pressure tested.The car makes it possible, but the driver makes it happen.
