Phil & Kneale:
Always good to hear from a few enthusiast and 200 20V owner.
As Phil mentioned, I used Econ and felt warm enough thinking the air was 
venting to floor and Defrost.  I was quite surprised when HOT air came from the 
dash & console center vents when switched to Bi-Level.  (I always skipped 
Bi-level as I thought it would cycle the A/C compressor......old school KH 110 HP 
4000Q I guess)

WRT: MFTS.
No low coolant warning (just brake bulbs :-) ), but I was wondering if the 
thermostat was the cause or whether the coolant level wasn't as high as I 
believed (or air pocket).  Then expanding when hot to reach the MFTS.

Let it idle and gauge reads fine (to 1/2 way) in about 10 minutes.  Cold is 
fine on the track, but winter heat keeps the windows viewable/useable & safer.

Thanks for the input gents:
