Additional Notes

  • Across the Alfa Romeo 155 petrol range, the four-cylinder Twin Spark engines (1.7, 1.8, and 2.0) share a cooling system capacity of 8.3 liters, while the later T.Spark 16V variants of the 1.6, 1.8, and 2.0 engines each require 8.4 liters — a modest but consistent increase of 0.1 liter over their Twin Spark counterparts.
  • The 155 2.5 TD carries the largest cooling system capacity in the lineup at 10 liters. Turbocharged diesel engines of larger displacement typically demand greater coolant volume to manage the additional thermal load generated by both combustion and turbocharger operation.
  • The 155 2.5 V6 cooling system holds 9.2 liters, reflecting the greater surface area and additional cylinder count of a V6 configuration compared to the inline four-cylinder petrol engines in the same model range.
  • The 155 Q4 2.0 Turbo cooling system capacity is 9.1 liters. The Q4 designation refers to the all-wheel-drive turbocharged variant, and the elevated capacity relative to the naturally aspirated 2.0 Twin Spark (8.3 liters) is consistent with the thermal demands of forced induction.
  • The 155 2.0 TD cooling system holds 8.9 liters, placing it between the four-cylinder petrol engines and the larger 2.5 TD in terms of coolant volume. The 2.0 TD covers the 1993-1997 model years, while the 2.5 TD spans the same period.
  • All ten configurations share an identical coolant change interval of 60,000 km or 24 months under normal use conditions, whichever comes first. The time-based limit of 24 months reflects the degradation of coolant additives over time regardless of distance traveled.
  • A check interval of 500 km is specified uniformly across all configurations. At 500 km, a vehicle is typically still within its early running-in period, making this an initial verification of coolant level and system integrity rather than a routine maintenance event.
