I have a leak that I can't see but it dribles down the front of the engine seemingly behind the water pump pully. A water pump leak is designed to travel to the back of the engine. Perhaps my car is so old and corrupted, this is not the case. The most leaking occures after the engine has cooled.
Do you think it is the water pump, or could it be something else. All hoses look fine. I removed the splash shield and looked at this problem from beneth the car.

Fluids can be deceiving when they leak. A little build up of oil seapage can force a leak into a new direction.

If you remove the belt for the water pump you can check for play. IF any then replace it.

Ideally a coolant system pressure tester is needed to best diagnose this leak. Putting pressure in it when it is cool will force the leak and make it easier to remove what is necessary to find it.
