Additional Notes
- The Mercedes-Benz 230 SL, W113 (Pagoda) carries a cooling system capacity of 10.8 liters, which is the total volume of coolant the system holds when fully drained and refilled — a figure relevant to complete coolant replacement rather than a partial top-up.
- The 250 SL and 280 SL variants both share a cooling system capacity of 12.9 liters, representing a notable increase of 2.1 liters over the 230 SL figure.
- The jump from 10.8 liters in the 230 SL to 12.9 liters in the 250 SL aligns with the engine displacement increase from the M127 to the M129 inline-six, where a larger engine block and cylinder head typically require a greater coolant volume to maintain thermal regulation.
- All three configurations list a normal use condition, meaning the 10.8-liter and 12.9-liter capacities apply under standard operating circumstances rather than a severe-duty or first-change scenario.
- The 250 SL (1966-1968) and 280 SL (1967-1971) share identical cooling system capacities despite being powered by different engine variants, indicating the cooling circuit volume was carried over between those two generations of the W113 platform.
