Develon (Doosan) Articulated dump trucks, DA

Coolant capacity & service interval

Develon Articulated dump trucks, DA models utilize coolant with a capacity range of 38 to 50 liters. Service intervals include checks every 8 hours and changes at 12 months/2000 hours or 12 months/4000 hours. The data covers 6 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Develon (Doosan) DA30 fitted with the Scania DC9 Stage IIIb/Tier 4i and Tier 2 engines shares identical cooling system capacities across both emission tiers: a dry fill of 45 liters and a service fill of 38 liters. The 7-liter difference between dry and service fill reflects the volume retained in the engine block, hoses, and heat exchangers after a standard drain, which is not recovered during a routine coolant change.
  • The DA40 with Scania DC13 engines, across both Stage IIIb/Tier 4i and Tier 2 variants, carries a dry fill capacity of 50 liters and a service fill of 42 liters. The larger cooling system volume compared to the DA30 corresponds to the physically larger DC13 engine displacing more heat and requiring greater coolant circulation capacity.
  • The DA45 with the Scania DC13 Stage V engine lists only a service fill capacity of 50 liters, with no dry fill value specified. The DA40 DC13 variants, by contrast, list both dry and service fill values, with the service fill at 42 liters — 8 liters less than the DA45 service fill figure despite sharing the same engine family designation.
  • The DA30 Scania DC09 Stage V lists only a service fill of 45 liters, matching the dry fill figure of the earlier DC9-equipped DA30 variants. Without a separate dry fill value listed, the service fill represents the working reference capacity for routine maintenance on that configuration.
  • Coolant change intervals differ between emission tiers on the DA30. The DC09 Stage V specifies a change at 12 months or 2,000 hours, while the DC9 Stage IIIb/Tier 4i and Tier 2 variants specify 12 months or 4,000 hours. The Stage V interval is half the operating-hour threshold of the earlier-tier engines, under the same normal use condition.
  • The same interval difference applies to the DA45 versus the DA40. The DA45 Scania DC13 Stage V calls for coolant changes at 12 months or 2,000 hours, while the DA40 DC13 Stage IIIb/Tier 4i and Tier 2 configurations specify 12 months or 4,000 hours. Both share the same 12-month calendar limit regardless of emission standard.
  • All six configurations across the DA30, DA40, and DA45 share a coolant check interval of every 8 hours under normal use conditions. An 8-hour interval aligns with a standard single operator shift, making the check a daily pre-operation or post-operation task in typical heavy equipment scheduling.
  • The DC9 Stage IIIb/Tier 4i and DC9 Tier 2 variants of the DA30, covering model years 2012-2021, carry identical capacity and interval specifications. The same pattern holds for the DA40 DC13 Stage IIIb/Tier 4i and Tier 2 variants over the same year range, indicating no cooling system specification change was introduced between those two emission tiers on either truck model.
