JCB Fastrac 150 Series

Coolant capacity & service interval

JCB Fastrac 150 Series coolant capacity ranges from 28 to 34 liters. Service intervals include checking every 10 hours and changing every 2000 hours or 24 months. The data covers 2 configurations.

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

Additional Notes

  • The JCB Fastrac 150 Series cooling system capacity differs by serial number range. Units up to serial number 636.000 hold 28 liters, while units from serial number 636.001 onward hold 34 liters, a difference of 6 liters between the two configurations.
  • The 34-liter capacity associated with the 636.001-onward build represents a notably large coolant volume, consistent with a heavy-duty agricultural tractor cooling system designed to manage sustained thermal loads across extended field operation.
  • Both serial number ranges share an identical check interval of every 10 hours of operation under normal use conditions, reflecting how frequently the coolant level is expected to be inspected rather than replaced.
  • The change interval for both configurations under normal use is 2000 hours or 24 months, whichever comes first. The dual-trigger structure means calendar time can mandate a change even when the hour threshold has not been reached, and vice versa.
  • A 2000-hour drain interval on a machine used in seasonal agricultural work could easily be reached over several years, making the 24-month calendar limit the more likely trigger in lower-utilization applications.
