Opel Karl, C16

Coolant capacity & service interval

Opel Karl and C16 models use coolant with a capacity of 4,2 liters. Service intervals occur every 12 months or 30000 km. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Opel Karl C16 cooling system holds 4.2 liters across all three configurations covered in the specifications: the 1.0 petrol in both its 2015-2018 and 2018-2020 forms, and the 1.0 LPG variant from 2016-2018.
  • A 4.2-liter cooling system capacity is a relatively modest figure, consistent with a small-displacement engine in a subcompact vehicle where the overall thermal mass and coolant circuit size are limited.
  • The check interval for the Karl C16 cooling system is set at 12 months or 30,000 km under normal use conditions, whichever comes first.
  • The 12-month or 30,000 km check interval applies uniformly to the 1.0 petrol and the 1.0 LPG configurations, with no differentiation in service frequency between the two fuel system types.
  • The 1.0 LPG variant, introduced in 2016, shares an identical 4.2-liter cooling system capacity with the standard 1.0 petrol engine, indicating no structural change to the cooling circuit was required to accommodate the LPG fuel system.
  • The 2015-2018 and 2018-2020 petrol variants carry the same 4.2-liter capacity and the same 12-month or 30,000 km check schedule, reflecting no revision to cooling system specifications between those two production periods.
