Ok so I had a problem with my heater valve(It cracked and was leaking) so I replaced it before I went on a 4 hour drive to go hunting then a 4 hour drive home. When I got home there was no problems and no leaks the next day I took a drive to the store in town came back and parked. the next morning I noticed a large coolant puddle under the front axle area. I didn't have time to look at it too closely over the next week coolant continued to leak, (without starting the motor) I looked a little closer today but I still cant find the source, there are still fresh drips on the steering components and on the bottom of the motor as seen in the pictures...



I checked the heater valve and all the hoses and they are all dry and seem to be intact.
I cannot figure out where it is coming from and it DOES NOT LEAK while the engine is on, Any help is greatly appreciated!!!!!!

Could it all be coming from under the water pump? It seems like a lot for a gasket leak but it's a common problem. It could be running down the front of the motor

its coming from under your water pump. Start it, put some fluid in, let it sit the driveway till it reaches temp and pressure look under for leaks. You should see some gunk/slime under the water pump. if its not the water pump just look around and trace back the leak to the source.
