Engine coolant dilemma.
Hey y'all. I have 2010 F150 XLT with a 4.6L 3V engine that is due for a cooling system flush. When searching for coolant the recommendations are different than my manual. My manual calls for orange but motorcrafts chart says yellow. Maybe my 2010 has a 2011 engine? Anybody (maybe a ford dealer mechanic?) know what I should use?

That's not hype, that's years of professional experience talking.
Op, follow the latest recommendation from Motorcraft charts. iirc yellow replaces what was in it. Rock auto. Com had the best price on Motorcraft concentrate with shipping it was still cheaper than anything local.

If you'd seen half the clogged up radiators due to Dex cool that I have, you wouldn't say that. I wouldn't put the crap in my worst enemies vehicle, well ok maybe an enemy but certainly no one else's.

Pick up a bottle of Prestone dex-cool and it lists the ford specification number on the back right beneath the GM specification number.
so every ford vehicle that came with ford orange coolant is doomed to have problems? And filled with coolant not good enough for your worst enemy? Give me a break.
OP - if you aren’t doing a complete flush, use the ford orange if you can find it, or the new yellow if you can’t. The yellow is fully backwards compatible with the orange.
don’t use tap water. Flush it with distilled and dilute it with distilled. Using tap water with an OAT coolant is bad JuJu and could definitely cause some of the sludge you see with dex-cool. Use the specified coolant, or equivalent replacement at the specified interval , and keep tap water away from the system and you will live a long and happy life.
if you are doing a complete flush, which is pretty hard to do correctly, then you can use whatever coolant you want.

Dexcool is fine (ORANGE) as long as it is not MIXED with others.. The PROBLEMS people have with ORANGE is when they add YELLOW or "MIXES WITH ALL" antifreezes to their engine..
I changed the ORANGE in my 90,000 mile 2013 F150 in 2019 after a little over 5 years and it was CLEAN and Great condition.... Flushed it once and refilled with DEXCOOL.... Ready for a second changed later this year.
