Page 8: Coolant Circuit
On keel cooling engines, the charge air cooler may be connected to the coolant cir- cuit. Higher power outputs for DI16 and DI13 with keel cooling have a separate cool- ant circuit for the charge air cooler, whereas all DI09 with keel cooling have a separate circuit. - Page 9 The expansion tank has a pressure cap with an opening pressure of 0.75 bar.

Information on dimensioning can be found in 01:05 Cooling system in the installa- tion manual for industrial engines. Note that marine engines have a greater cooling requirement due to their water-cooled exhaust manifolds. 02:05 Issue 8.0 en-GB © Scania CV AB 2017, Sweden... -
Page 23: Connecting An Auxiliary Oil Cooler
If an auxiliary oil cool- ant is connected, an external thermostat must be fitted and the engine thermostat must be locked in the open position. 02:05 Issue 8.0 en-GB © Scania CV AB 2017, Sweden... -
Page 24: Connecting A Cab Heater
If external circuits are connected, there must always be venting on these circuits. On the DI09 and the DI13, the cab heater intake line is routed to the connection above the coolant pump on the cylinder block.
