Coolant drain / refill
I've got a 2009 2500HD w/ the 6.0L Vortec.
Wanting to drain and fill the coolant. Trying to avoid the dexcool issues I've seen online.
Can anyone give me some tips on how to do this? I can't find a drain plug on the bottom of the radiator, and I can't seem to figure out how to get to the lower radiator hose to take it off.
Any tips or pointers? ANything special I need to know if I'm going to drain and refill coolant?
