[husker boxster]

The coolant may be "lifetime", but the water pump isn't. Porsche never has to live up to the lifetime challenge because the wp fails anywhere from 3-5 yrs. You're probably living on borrowed time if you haven't changed your water pump. My Boxster's went out at 3.5 yrs & 26K mi. Luckily it was in warranty. I was thinking of changing the Cayman's soon b/c it's a yr older, but I'm going to roll the dice since it's a CPO car.
