Additional Notes
- The Opel Combo B 1.2i (1993-1996) cooling system holds 5.9 liters, the largest capacity among the petrol variants in the lineup.
- The 1.4 (1996-2001) and 1.4i (1993-1996) share an identical 5.8-liter cooling system capacity, despite covering different production periods.
- The 1.4i 16V (1994-2000) has the smallest cooling system capacity across all listed variants at 5.6 liters. The 16V designation refers to a four-valves-per-cylinder head design, which typically affects combustion chamber geometry and can influence coolant jacket volume.
- The 1.7 D diesel variant, across both its 1993-1996 and 1996-2001 production periods, carries a 6.0-liter cooling system capacity. Diesel engines generally run at higher thermal loads than petrol equivalents, and a larger coolant volume supports greater heat dissipation.
- All six configurations share a uniform 24-month coolant change interval under normal use conditions. A 24-month interval is associated with conventional coolant formulations, as opposed to extended-life coolants that can reach 5 years or more between changes.
- The capacity difference between the 1.7 D at 6.0 liters and the 1.4i 16V at 5.6 liters represents a 0.4-liter spread across the full range of listed variants, reflecting the variation in engine size and design across the Combo B model range.
