Additional Notes
- The JCB Fastrac 155 Series cooling system capacity differs by serial number range, with units up to serial 636.000 holding 28 liters and units from serial 636.001 onward holding 34 liters, a difference of 6 liters between the two configurations.
- A 28-liter coolant capacity applies to Fastrac 155 units produced within the 1991-1997 period with serial numbers up to and including 636.000, representing the earlier production variant of the cooling system.
- The 34-liter capacity associated with serial numbers from 636.001 onward indicates a larger cooling system volume, which typically corresponds to a revised or expanded engine cooling circuit requiring a greater total fluid fill.
- Both serial number variants share an identical check interval of every 10 hours of operation, reflecting a frequent inspection requirement consistent with heavy-duty agricultural machinery standards.
- The change interval for coolant across both configurations is specified at 2000 hours or 24 months under normal use conditions, whichever comes first, meaning time elapsed can trigger a service requirement even before the hour threshold is reached.
- The 2000-hour drain interval is relatively long by agricultural equipment standards and is tied specifically to normal use conditions in both rows, applying equally regardless of the 6-liter capacity difference between the two serial number ranges.
