Shantui Pipe layer

Coolant capacity & service interval

Shantui Pipe layer coolant capacity ranges from 79 to 121 liters. Maintenance requirements include checks every 10 hours and fluid changes every 2000 hours or 12 months. The data covers 4 configurations.

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

Additional Notes

  • The Shantui SP25Y and SP25YL, both fitted with the Weichai WD615T1-3A engine, share an identical cooling system capacity of 79 liters. When two distinct configurations carry the same fill volume, the cooling circuit architecture is effectively the same across those variants.
  • The SP70Y and SP90Y, equipped with the Cummins NTA855-C360 engine, require 121 liters of coolant. A capacity of 121 liters reflects a substantially larger cooling circuit, consistent with the higher displacement and power output associated with the NTA855 series engine compared to the WD615T1-3A.
  • Across all four configurations, the coolant check interval is set at every 10 hours of operation. A 10-hour check interval is among the most frequent in heavy equipment maintenance schedules, indicating that coolant level and condition are treated as a daily or near-daily inspection point.
  • The coolant change interval for all four pipe layer configurations is 2000 hours or 12 months, whichever comes first. The dual-trigger structure means that even machines with low annual operating hours are subject to a calendar-based change, since coolant degrades chemically over time regardless of use.
  • All four rows are classified under normal use conditions. In heavy equipment service documentation, a normal use designation typically applies to standard operating environments, as opposed to severe conditions such as extreme temperatures, heavy dust, or continuous high-load cycles, which would ordinarily shorten service intervals.
  • The 53-liter difference in cooling system capacity between the WD615T1-3A-powered models at 79 liters and the NTA855-C360-powered models at 121 liters represents a roughly 53% increase in coolant volume. This scale of difference between the two engine families has a direct bearing on the quantity of coolant required at each scheduled change.
