concern water pump

[moosey]

I have 24,000 miles on a water pump that i replaced last year. Not loosing any coolant, but just noticed this past week that at the very bottom where the torx screw is there is always a tiny dry spot of coolant. Could this be a sign that it is failing? How often should the water pump be replaced?

I have a similar problem today. I bought my car in June 2006, I can see the coolant was came out from the expansion valve when it was new & full. After 38.5 K miles, the level of coolant dropped below the min. marking at the reservoir this winter. All these years, the coolant level has been coming down slowly. I took my car to the dealer for annual state inspection today . I mention this to the SA, he instruct the mechanic pay attention to this issue. Afterward, he inform me the water pump seal has very small leak and needs to replace. I live in north Texas, DFW. My car is 997-1, I came into this forum b/c I do not see any water pump thread in my forum. I just want to know if this issue is coming with Jun. 2006 production. I never add any coolant. I always garage the car and hardly stressed on the engine. I just replace the battery 2 weeks ago after 4.5 yrs of production date. Even this repair does not cost me anything b/c of extended warranty I paid at closing, I just do not want to repair if the loosing coolant is common from the expansion valve. I usually drive the car 1.5 times ea. week.
