What do you use?

My 2018 gc105 needs a coolant change (I know it's way overdue) . I've searched for what type/brand/color to use and still confused what antifreeze to get, so asking fellow GC owners, what do you use ? Is the Super Tech Extended Life at Walmart any good?

Use pink/red coolant. It’s going in all the heavy duty diesel trucks now. My AGCO/Massey dealer has switched over to it on their tractors, too.

“Zerex Fully Formulated Antifreeze/Coolant from Valvoline is a complete ethylene glycol-based formulation designed to meet the harsher demands of heavy-duty diesel engines such as Cummins, DDC, MACK, Navistar and Paccar. Not to mention, it’s considered a universal engine coolant that meets the low-silicate formulation required by the heavy-duty trucking industry.”
