Answer
Paul
More info please.
How many miles on this engine?
Is it an automatic, or strait drive?
What is the max temperature reached ?
When does it occur?  In traffic? On the open Road?
Idling?
Does it boil over with a loss of coolant?
Is the antifreeze at the correct blend for this vehicle as indicated by a hydrometer?
Is your coolant recover tank connected properly to the radiator and is the fluid at the proper level?
Is your radiator fan electric, or does this V12 use a mechanical clutch/fan mounted to the engine block?
Is there a mechanical shutoff valve under the hood for the heater?
Is the heater vent blowing full air?
The Air Conditioning us used on the heat cycle when you turn on the defrost. It dehumidifies the air for a more rapid moisture removal on the glass.

Please answer these questions and we can start from there.
