OK...trying to figure out if I have a cooling problem or not and having a brain fade day.

With an ambient temperature of 15 degrees, and trundling around at 30ish, car seems to keep cool quite happily.

Sat on the drive idling with an ambient temperature of 15 degrees, temperature heads to 100degrees, fan kicks in and cools back down to 90. Fan turns off, goes back up to 100, fan kicks in, goes back down to 90

Does this sound OK..bearing in mind the car needs to withstand the heat of Le Mans in 2 weeks.

Sounds about right to me too,

What sound? I hear no sound?
