Additional Notes

  • The London Taxi Company TX4 Euro 4, covering model years 2006-2012, carries the largest cooling system capacity in the TX range at 12 liters, indicating a notably larger coolant volume than the other TX4 variants.
  • The TX4 2.4 (2013-2016) and TX4 Euro 5 (2012-2015) share an identical cooling system capacity of 7.3 liters, the smallest figure across all TX configurations listed.
  • The TX4 Euro 6 (2015-2017) cooling system holds 10 liters, placing it between the smaller 7.3-liter Euro 5 and the larger 12-liter Euro 4 in terms of coolant volume.
  • All four TX4 variants share the same change interval under normal use conditions: 100,000 miles or 24 months, whichever comes first. The mileage threshold is absent from the earlier TXI and TXII specifications, which list only a 24-month interval.
  • The TXII (2002-2006) is the only TX model in the specifications to list two distinct capacity figures: a full system capacity of 9 liters and a service fill capacity of 6.5 liters. The service fill figure reflects the amount of coolant needed during a routine drain-and-refill, which is typically less than the total system volume because some coolant remains in the engine block and heater core.
  • The TXI (1997-2002) cooling system capacity of 10 liters matches the TX4 Euro 6 figure, despite the two variants being separated by over a decade of production.
  • The shift from a 24-month-only interval on the TXI and TXII to a combined mileage-and-time interval on all TX4 variants reflects a more structured maintenance schedule tied to vehicle usage rather than time alone.
