Additional Notes
- The Shibaura SD series cooling system capacities across the 1985-1988 model range span from 6 liters on the smaller configurations up to 11.5 liters on the largest, reflecting the stepped increase in engine displacement across the lineup.
- The SD 3200 and SD 3240 share an identical 6-liter cooling system capacity, as do the SD 3600 and SD 3640, indicating that the paired model variants within each size class carry the same coolant volume requirement.
- The SD 4500 and SD 4540 specify an 8.5-liter cooling system capacity, placing the mid-range models between the 6-liter smaller variants and the 11.5-liter larger ones.
- At 11.5 liters, the SD 5000 and SD 5040 hold the largest cooling system volume in the 1985-1988 SD series, a capacity that corresponds to a more substantial engine requiring greater thermal management.
- All four model groupings share a uniform 10-hour check interval for the cooling system under normal use conditions, meaning coolant level verification is tied to operating hours rather than calendar time.
- The coolant change interval across all 1985-1988 SD series configurations is set at 12 months under normal use conditions, establishing an annual replacement cycle regardless of the differing system capacities between models.
