Which coolant to use?
I recently bought a 2004 Excursion with a 6.0 and 157000 miles on it. Love the truck! I'm going to be doing my Oil, Fuel, and Air filters this weekend. All the filters are Motorcraft. I would like to flush and refill the cooling system. I'm reading about EGR failures due to coolant chemical levels and things like that. Do I need to use Ford antifreeze or can I use an aftermarket brand like Zerex G5? Are there any guidelines to go by? Any tips or tricks for this. I know my way around cars but I'm not as well versed in the ways of the 6.0. Any guidance would be appreciated. Thanks
