Additional Notes

  • The Opel Combo A 1.6 D carries the largest cooling system capacity in the lineup at 7.6 liters, a figure consistent with the greater thermal load diesel engines place on cooling circuits due to their higher compression ratios and combustion characteristics.
  • The 1.3 petrol variant from 1986-1989 holds 7.0 liters of coolant, which is notably higher than the later 1.4i and 1.6i fuel-injected variants despite having a smaller displacement, reflecting differences in engine architecture and cooling jacket design between older carbureted and newer injected units.
  • The 1.4i and 1.6i fuel-injected variants, both spanning 1991-1993, carry capacities of 6.2 and 6.4 liters respectively, the lower figures likely attributable to more refined engine packaging and updated cooling system designs introduced in the early 1990s.
  • The 1.6 petrol and 1.6i share an identical cooling system capacity of 6.4 liters despite representing different generations of the same displacement engine, with the carbureted 1.6 running from 1986-1990 and the injected 1.6i from 1991-1993.
  • The 1.7 D diesel, covering 1989-1993, holds 6.5 liters, placing it below the earlier 1.6 D at 7.6 liters, a difference that may reflect revised cooling system geometry in the later diesel unit.
  • All six configurations share a uniform 24-month coolant change interval under normal use conditions. A 24-month interval is standard for conventional silicate-based antifreeze formulations, which degrade in corrosion inhibitor effectiveness over time regardless of mileage.
