Hey BimmersInGA, I too am a BMW guy in GA (Atlanta) who started tweaking a Boxster about a year ago.

They obviously have some of the same German thinking with plastic mechanical and pressure parts in the cooling system, etc. I always replaced my BMW plastic parts throughout the car at about 100K miles, and it sounds like that my be a good approach for you with your P-car also. I'm guessing the plastic water box on one of your coolers is cracked.

Everyone on these boards seems to think P-car coolant is some special fluid from Heaven, so you might want to get some. Personally, I would think the BMW coolant would be fine, but you never know, and it is not too an expensive insurance.

You will also find that many of the P-car purists think Mobil 0w30 is the only suitable oil for these cars. Personally I don't trust the stuff, and use Castrol TWS - same as in my M3.

You will find that all parts for these cars are very highly priced, even from the aftermarket.

It is sure to be an expensive journey, but there really is no substitute...

Good luck.
