Last week, I changed out(D&F only) the coolant in 3 vehicles
I know there are many folks who don't like AM/AM but, I really haven't had any issues using them.
I used PEAK LL AM/AM 50/50 in the Mazda3 and Nissan Altima. And used PEAK Global Lifetime 50/50 in the wifes Lexus.
I do each car about every 3 years so, the cooling systems are at the very least, well maintained!
