Additional Notes
- The Volvo Buses & Coaches (EU) 9700/9800 and 9700/9900 series all share a cooling system capacity of 55 liters, which is a substantial fill volume consistent with the large-displacement engines and extended cooling circuits found in full-size coach applications.
- The 9700/9900 (4x2) Euro b,c,d,e with D11 engine starting from 2015 carries a 55-liter cooling system capacity under normal use conditions, with a change interval of 48 months.
- The 9700/9900 (6x2) Euro b,c,d,e with D11 engine, also from 2015, matches the 4x2 variant exactly at 55 liters capacity and a 48-month change interval under normal use, indicating the additional axle configuration does not alter the cooling system volume or service schedule.
- The 9700/9800 (4x2) Euro 6e with D13K420, D13K460, and D13K500 engines from 2022 onward also specifies 55 liters and a 48-month change interval under normal use, meaning the higher-output D13K engine family shares the same coolant service parameters as the D11-equipped models.
- A 48-month coolant change interval, applied here under normal use conditions across all listed configurations, represents an extended-life coolant schedule. Standard heavy-duty coolants typically require more frequent changes, so a 4-year interval reflects the use of a long-life formulation suited to these coach applications.
