I checked my coolant today and I was a tad low. I have a gallon of Zerex G-05 antifreeze.
Is this compatible with what came with the truck? The owner's manual says it uses HOAT antifreeze.
Is Zerex G-G5 Hoat?
Thanks,
Jack

 

If you are just adding a little bit, I would just add distilled water. I used to have a comparison chart but it is on my other PC and I'm not near it right now.

 

Zerex G-05 is correct:
