Hi,

As mentioned, check the lines for leaks. It could have been improperly Bled, there is a specuific Bleed Valve for the Coolant which lives under the escutcheon covering the Oil and Coolant spouts. You must pry up/off this escutcheon and then you'll see the Bleed Valve. You pull up on the wire lever and run the Car. There is a specific sequence to Bleeding the system.

But, if you mention the Tank being emptied, there is likely a leak as well. Porsche put out a TSB - 3/00 3848 3 calling for replacement of the Spring-Clamps with Screw or Worm Clamps, be sure this was done. As mentioned, use silicate-free Coolant to prevent gumming up the system with Silica Gell which will fall from solution if incompatible coolants are used.

So far as the Boxster vs the Miata, they are not equals in many respects. Unfortunately, Reliability and Maintenance are one of these, and the Miata wins this category Hands Down...

Happy Motoring!... Jim'99
