Its that time of this trucks cycle where I’m draining and filling the coolant back up. But after buying Prestone and Toyota and upon reading older threads I don’t know which I should use. So I’m seeking more modern/relevant input on what do you guys use. I know I’m not the only one that contemplates this. I’m hoping this thread becomes helpful for those who are unsure.What’s your 0.02 and why do you use the coolant you use?
