I am going to have my thermostat changed tomorrow in my friends shop. Would you all go ahead and have the radiator flushed out? He has the machine there to do it properly. I am leaning towards going ahead and doing it. I am sure there is a bunch of crap in there after 200,000 miles.
Also would you all fill it back with a good quality antirfreeze/water mix or spend the extra bucks on the Shell Rotella pre-mix?
