If you go to "cooling system seminars" I think I will just shut up and listen to you! Your description doesn't make any sense at all to me though. I thought that the higher temperature-range thermostats restricted coolant flow resulting in higher coolant temperatures. Something has to be happening to cause the coolant to be cooler? If not increased flow, what is it?

TBarrow: Thanks much for the comments! A 1/4" tube and a couple of clamps... Ka-ching! Strange that your Yukon XL had a 160 degree thermostat... I am a REAL sucker for "If a little is good, a LOT is even better". Why go with a 172/178 degree thermostat if I can get a 160 for less money?

Thanks a lot guys!
