Thanks guys. So, is flushing these beast fairly simple or is it something I should take in. I have swapped many an engine in my day and like to think of myself as being pretty competent around tools but, this thing scares me. It isn't an old Willys jeep or FE. A lot of hoses and not much room. And, I don't want to screw up my perfectly running $40,000 truck.
Also, if I am going to flush it, how tuff of an install is the coolant filter? I also saw mention of some antifreeze that is good for 200,000 plus miles, anybody know the brand name for me?
Thanks
