Additional Notes
- The Ford Ka Mk II (B420) coolant system capacity differs noticeably between its two engine options. The 1.2 Duratec holds 4.85 liters, while the 1.3 TDCi Duratorq requires 6.3 liters, a difference of nearly 1.5 liters attributable to the diesel engine's larger and more complex cooling demands.
- Both the 1.2 Duratec and 1.3 TDCi Duratorq share an identical coolant change interval of 120 months, which equals a 10-year service life per fill under normal use conditions.
- A 120-month coolant change interval is consistent with modern long-life coolant formulations, which use organic acid technology (OAT) or similar chemistry to maintain corrosion inhibitor effectiveness over extended periods without requiring intermediate changes.
- Both engine variants specify a coolant level check at every 1,000 km under normal use conditions. A check interval of 1,000 km is relatively frequent and reflects a routine inspection rather than a fluid replacement task.
- The 6.3-liter capacity of the 1.3 TDCi Duratorq cooling system is a notably high figure for a small city car engine, indicating a more extensive cooling circuit that accounts for the thermal management requirements of a diesel combustion cycle.
- All specifications across both engine variants are listed under normal use conditions, meaning the capacity and interval values apply to standard operating environments without modification for severe or first-change scenarios.
