| Type | Specifications |
|---|---|
| Cobra 428 (1967-1973) |

Additional Notes
- The AC Cobra coolant system capacity of 15.9 liters applies across all three engine variants covered in the specifications: the 289, 427, and 428.
- A 15.9-liter cooling system capacity is a relatively large figure for a sports car of the Cobra's era, reflecting the substantial displacement of the Ford V8 engines fitted across the 1963-1973 model range.
- All three configurations carry a normal use condition designation, meaning the 15.9-liter capacity figure is associated with standard operating conditions rather than severe or high-stress service environments.
- The 289 variant covers model years 1963-1965, the 427 covers 1965-1967, and the 428 covers 1967-1973, yet all three share an identical coolant capacity, indicating no variation in cooling system volume across the different engine displacements or production periods.
