Here's what the gauge looks like my 2001 2500hd, and you can see what it indicates as being too hot, this being said, the hottest I've ever seen it is about 180 in the summer, unloaded.

In a greased 11x7-in. baking dish, layer the spaghetti, cream cheese mixture and meat mixture. Top with shredded cheese. Bake, covered, at 350Â° for 25 minutes.
