Additional Notes

  • The Vauxhall Astra G Classic 1.4 16V carries a coolant capacity of 5.2 liters in standard configuration, rising to 5.5 liters in vehicles equipped with air conditioning, reflecting the additional thermal load introduced by the air conditioning circuit.
  • The 1.7 CDTi engine requires a notably larger coolant fill of 7.1 liters compared to the 1.4 16V, a difference consistent with the greater heat rejection demands of a diesel engine relative to the smaller petrol unit.
  • Both the 1.4 16V and 1.7 CDTi share an identical service check interval of 12 months or 30,000 km under normal use conditions, whichever comes first.
  • The 1.4 16V specification designates red fluid for the cooling system, a detail absent from the 1.7 CDTi entry, indicating a color-coded coolant type specific to the petrol variant's cooling circuit.
