last year I decided to be a good Porsche boy and flush my coolant even though they say to never do this. That just didn't make sense to me after 10 years. The coolant was cheap($30) but the labor was a bit more than I was expeciting since I've never done such a job or have the tools for it. All in it was about $300.

Well less than 12 months later the expansion tank crumbled under the pressure of my merciless driving and a tiny hairline crack dumped all the coolant over the course of a day. So you guessed it...time to do it all over again plus a new tank (about $350 on Ebay).

Save yourself $300 by doing it once.
