Where this came from
  • Ford Owner's Manual - Mustang Capacities and Specifications (5.0L) — source

The coolant type is a single-source spec from the owner's manual or OEM parts catalog — we never dress that up as cross-checked against two sources, because it isn't. The system capacity carries our verified badge only when two independent sources agree on it. Coolant color is a rough hint at chemistry, not a guarantee — match the spec, not the color, and never mix families. Your owner's manual is always the final word.
