CM Water pump @ 25k miles again at 43k?

I was under the car doing a bump steer kit and setting alignment & noticed a really damp muddy looking front spring, top and bottom. The damp/muddy collection trails back to the pan.

It also covers the front crank pully area.

It does not seem to be oil.

Topside there is a big damp seepage mark on the pass side front of engine.

No drips on the ground.

Inspection mirror & light could not pinpoint any active leak.

The w/p dome pully covers the front of the w/p so impossible to see in there.

The level in the overflow seems about where I usually keep it, but it's such a big tank it's hard to tell if the level is dropping if it's a slow leak.

Any suggestions to further diagnose? Wait for the orange puddle? BTW I just checked the service records and my dealer put this w/p in @ 25k miles 11/07 so if it is the w/p I got about 20k miles out of it. That about right?

Thanks.

I think I can get a pressure tester.

Check your top hose at the neck, I had coolant running down the bottom of the hose and to the center of the car, looked like the water pump. Turned out to be a crack in the seem of the radiator at the top hose. It's only plastic. New radiator (easy fix ). then the water pump went a month later.
