Redrock Telehandlers, TH

Coolant capacity & service interval

Redrock Telehandlers, TH models require coolant with a capacity of 22.5 liters. Service intervals include checks every 10 hours and changes every 1000 hours or 24 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 Redrock TH280, TH280S, and TH320 all share a 22.5-liter cooling system capacity when fitted with the Iveco 4.5 Tier 3 engine, as does the TH300 with the Perkins 1004.4T engine, placing all four configurations at the same fill volume regardless of engine origin.
  • A 22.5-liter coolant capacity is a relatively large figure for a construction machine cooling system, consistent with the thermal demands of turbocharged diesel engines operating under sustained load conditions typical of telehandler work cycles.
  • The TH280 with the Iveco 4.5 Tier 3 engine carries a coolant check interval of 10 hours, which corresponds to a daily or near-daily inspection frequency under normal operating conditions, alongside a change interval of 1,000 hours or 24 months, whichever comes first.
  • The dual-trigger change interval of 1,000 hours or 24 months on the TH280S and TH320 reflects standard practice for coolant degradation, where both operating time and calendar aging affect inhibitor depletion and corrosion protection independently.
  • The TH300 with the Perkins 1004.4T engine, covering the 1999-2004 production span, lists only a capacity value of 22.5 liters with no check or change interval specified in the row data, distinguishing it from the Iveco-engined configurations.
  • The TH280S shares identical cooling system specifications with the TH280, including the 22.5-liter capacity, 10-hour check interval, and 1,000-hour/24-month change interval, despite covering a longer production span of 2003-2009 compared to the TH280's 2003-2006 range.
  • The TH320 with the Iveco 4.5 Tier 3 engine, introduced from 2009, carries the same cooling system service schedule as the earlier TH280 and TH280S, indicating continuity in the Iveco engine's coolant maintenance requirements across different telehandler model designations.
