Hi,
No, the Climate Control Diagnostic reads in °C only - A simple method to convert °C to °F is to double the °C and add 30, so 93°C = 216°F - (93°C * 2 = 186 + 30 = 216°F).
The basic thing about Coolant Temp is that you want to keep it liquid as this will carry away the most heat and the liquid Coolant will flow to all the surfaces within the water jackets, Steam, a gas will not. This is why Cooling Systems are pressurized, because Coolant will remain a liquid at temps higher than standard (STP) boiling point. Water boils at 212°F, with the 13psi cap it boils at 245-250°F, with 50% antifreeze it boils at 265°F and at 70% antifreeze it boils at 276°F.
But, remember, your Oil carries away 60% of all the heat the engine produces, this is just as important a temperature value as the coolant. That said, 216°F is a little on the high side (not fatally, but high) for normal conditions. Make sure both your fans are working (turn on AC) and that both radiators are free of debris (a common problem). No two cars are exactly the same, so some variation is normal.
The only reason Temp is important below 240°F is that some ECUs (DME in Porsche Parlance) will go into Closed Loop operation at a pre-set temp, I haven't reasearched how or at what temp the Boxster does this. Hope this helps...
