Whats up guys, i finally got a dmax so now the fun begins. it is a 02 with 107,000 miles. I want to flush the radiator to freshen things up a bit. My question is do you guys use the dex cool antifreeze or do u change it for the green stuff. The reason i ask is because i know that the dexcool doesnt resist corrosion as much of the green stuff. Also do u guys use any coolant additives and what kind do u use? Thanks for the input.
