Today I came out during my lunch break and look underneath the Jeep and see a small puddle of coolant. I got under the car and it's right where the lower rad hose goes into the thermostat housing. It is dry around the rest of the hose and just appears to be leaking at the bottom part. When the car is running it is a constant drop every 2-3 seconds. I'm not sure if I should just replace the lower radiator hose or if this is most likely a case of the water pump about to fail and leaking through the weephole? As I said before, I could not see any coolant anywhere other than the bottom half of the lower rad hose but I'm not sure if this is a common problem. It's a 2002 4.7HO btw.
