Additional Notes
- The Vauxhall Astra 1.2 (1982-1984) carries a cooling system capacity listed as a range of 5.7 to 6.1 liters, which reflects variability in the total fill volume depending on factors such as body style or heater circuit configuration.
- The 1.3 engine variant holds 7 liters of coolant, a notably higher figure than the 1.2 despite the modest displacement difference, suggesting a larger radiator or extended circuit in the 1.3 cooling system.
- Among the petrol variants, the 1.6 carries the largest cooling system capacity at 7.7 liters, exceeding both the 1.2 and 1.3 configurations by a meaningful margin.
- The 1.6 D diesel variant specifies a capacity of 7.5 liters, which is 0.2 liters less than the petrol 1.6 despite sharing the same displacement figure, indicating a slightly different cooling circuit layout between the two 1.6 engine types.
- The 1.8 GTE, available from 1983-1984, shares the 7.5-liter capacity figure with the 1.6 D, even though the GTE is a higher-output petrol unit, placing both at the same service fill volume.
- All five configurations across the 1982-1984 range share a uniform coolant change interval of 24 months under normal use conditions, meaning no variant within the range calls for a shorter or extended service cycle.
