Taz,
Thank you for all of your advice. I'll see about ordering the t-stat today on-line or go to a local parts house and see if they carry one.

The air temps here in Vegas do get to below freezing in the winter, hell last winter I had snow in my front yard which I didn't think was possible for Vegas but yet it happened. Anyway what problems if any am I going to have running the truck when the temps get down towards freezing? Do I let the truck idle in the garage with the door open of course until it reaches normal operating temp then head out? Or is it not a big issue until the air temps get down to -20 which it never get to here in Vegas? I understand the dealership has to give a safe answer because they don't know where I am going to be driving. On the on the other hand I don't want to do something to the truck which is going to dictate where I can drive. I mean if I put the 160 t-stat in am I going to have problems driving to say Colorado to go skiing in the winter?

Thanks again to everyone who has given me some advice.
