Additional Notes

  • The JCB Fastrac 3155 cooling system holds 34 liters of coolant, while the Fastrac 3185 holds 33 liters, meaning the 3155 requires 1 additional liter to reach a full service fill.
  • Both capacity figures represent a full cooling system service fill under normal use conditions, accounting for the radiator, engine block passages, and associated hoses.
  • The 1-liter difference between the Fastrac 3155 and Fastrac 3185 cooling system capacities indicates a variation in engine or cooling circuit design between the two models despite their shared platform lineage.
