My 97 1 ton chevy (454) came with the red and the owners manual says 100,000 miles, no service on the cooling system, except for routine topping off.

I have 80,000 miles an 11 years on it wth no trouble. It is beggining to show signs of runnig a tad hotter, which I attribute to likely sludge formation in the radiator. About ready for a flush me thinks .............
