Additional Notes
- The Holden EK cooling system capacity is 9.1 liters across the Panel Van, Special, Standard, and Utility body configurations when paired with a manual transmission.
- When fitted with an automatic transmission, the cooling system capacity across all four EK variants drops to 7.96 liters, a reduction of roughly 1.14 liters compared to the manual transmission figure.
- The lower capacity associated with the automatic transmission configuration likely reflects a difference in the routing or volume of the cooling circuit, as automatic transmissions of that era commonly incorporated a transmission fluid cooler within the radiator, which can alter the overall coolant volume the system holds.
- All four body styles covered by the 1961-1962 specifications share identical cooling system capacities under both transmission conditions, indicating no variation in the cooling system design between the Panel Van, Special, Standard, and Utility variants.
- All capacity figures listed apply under normal use conditions, meaning the values represent standard operating service fills rather than a dry or overhaul fill that would account for residual fluid in a previously used system.
