Valtra (Valmet) T5 Versu

Additional Notes

• The Valtra T5 Versu cooling system capacity is 28 liters across all seven variants in the lineup, from the T145 Versu through to the T255 Versu. A uniform capacity across a wide power range indicates a shared engine block architecture or cooling circuit design rather than scaled cooling volumes per output class.
• The 28-liter figure represents a service fill capacity, meaning the volume of coolant required to fill the cooling system during a standard drain-and-refill service, as opposed to a larger overhaul figure that would account for additional passages flushed during a full engine-out procedure.
• A coolant check interval of 10 hours applies to all seven variants under normal use conditions. In agricultural machinery, a 10-hour check interval aligns closely with daily operational cycles, since tractors in field use commonly accumulate hours at that rate during peak seasons.
• The coolant change interval is set at 2400 hours or 24 months, whichever comes first, under normal use conditions. The dual threshold means time-based degradation of coolant additives is accounted for even when annual operating hours remain low.
• All seven variants, the T145, T155, T175, T195, T215, T235, and T255 Versu, share identical check and change intervals. No variant carries a shortened or extended interval relative to another, despite the spread in power ratings across the range.
• The 2400-hour change interval is notably long by agricultural equipment standards, where intervals of 1000-2000 hours are more common for coolant. A 2400-hour threshold typically reflects the use of extended-life coolant formulations, which rely on organic acid technology to slow additive depletion over time.
