    Default radiator drain plug missing

    I have a 2006 chevy silverado 2500HD 6.0 4X4 (bought used). I went to drain the coolant and flush out the system but to my surprize the drain plug and hose were not there. I read somewhere that they stopped putting drain plugs into the radiator to save money. Is this true or is my drain plug broken off inside the rad. If so then I'll have to drain it old school and pull off the bottom hose.(which I'll have to do anyway as I have no drain plug.)

    I am not sure if it's missing but I only do mine the old school way. I have broken two valves and could not repair them, pulling the hose is a little messy but easier. IMO

    It is sad, but true. My '03 Trailblazer and '04 Colorado do not have drain plugs. Manual says to pull the hose and drain. Its messy, but it works.

    Good to know its just not there rather than broken off inside. Thanks for the info. I feel better knowing Its not broken.
