I have a 2005 Meridian , cat. 350. I don't know if I need to change the antifreeze , the book don't say much about that, I only have 14,000 Miles. Any help will be appreciated , thank you so much...
They all need to be tested. Check with CAT and you can look at it. If it is Red, it is extended life, good for 350,000 before you put in a bottle of additive.
