Additional Notes
- The Chrysler Horizon (USA / CAN) cooling system capacity holds at 6 liters across the 1.1, 1.3, and 1.5 engine variants for the 1977-1980 model years, indicating a shared cooling system architecture despite the differing displacement figures.
- The Horizon SX carries a slightly larger cooling system capacity of 6.2 liters for the 1978-1980 period, a modest increase of 0.2 liters over the standard engine variants.
- All four configurations list normal as the use condition, meaning the stated 6 and 6.2 liter capacities apply to standard operating environments rather than severe-duty or special-case service scenarios.
- The capacity figures listed represent cooling system fills, which in service practice account for the total volume of coolant held within the radiator, engine block passages, heater core, and connecting hoses rather than a partial or drain-and-refill quantity.
- The Horizon SX entered the specification range one year later than the 1.1, 1.3, and 1.5 variants, with coverage beginning in 1978 rather than 1977, while all four rows share the same 1980 end year.
