Additional Notes

  • The Honda PCX 125 produced from 2010-2012 carries a cooling system capacity of 0.7 liters, which is notably higher than the 0.5-liter figure shared by all later PCX variants. A larger coolant volume generally reflects a bigger or differently configured cooling circuit in the earlier engine design.
  • From 2013 onward, the PCX 125 cooling system capacity dropped to 0.5 liters, a figure that also applies to the PCX 125 E5, the PCX 150, and the PCX 160. The reduction from 0.7 liters to 0.5 liters between the early and revised PCX 125 generations points to a redesigned cooling circuit in the 2013 engine update.
  • The 24-month coolant change interval applies under normal use conditions to the PCX 125 across both its 2010-2012 and 2013-2020 generations, as well as to the PCX 125 E5 and the PCX 150. A 24-month interval is a standard recommendation for conventional ethylene glycol coolant, which degrades in pH and corrosion inhibitor effectiveness over time regardless of mileage.
  • The PCX 160 stands apart from all other listed variants with a 36-month coolant change interval under normal use conditions, while retaining the same 0.5-liter capacity. A longer service interval of this kind is typically associated with extended-life coolant formulations, which use organic acid technology (OAT) or hybrid organic acid technology (HOAT) inhibitors that resist depletion more slowly than conventional coolants.
  • The PCX 125 E5 designation refers to the Euro 5 emissions-compliant version of the 125cc engine, introduced from 2020. Despite the updated engine specification, the cooling system capacity and the 24-month change interval remain identical to the post-2013 PCX 125 figures.
