Pontiac Grand Am (EU)

Coolant capacity & service interval

Pontiac Grand Am (EU) coolant capacity ranges from 8,2 to 12,9 liters. The service interval for coolant is 240000 km. The data covers 2 configurations.

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

TypeSpecifications
Grand Am 2.2 16V (2002-2005)
  • Use: Normal
  • Capacity 8,2 liter
  • Change 240000 km
Grand Am 3.4 V6 (1999-2005)
  • Use: Normal
  • Capacity 12,9 liter
  • Change 240000 km

Additional Notes

  • The Pontiac Grand Am (EU) 3.4 V6 carries a coolant capacity of 12.9 liters, which is notably larger than the 8.2 liters specified for the 2.2 16V variant, reflecting the greater thermal demands of a six-cylinder engine compared to a four-cylinder unit.
  • The 2.2 16V engine, available from 2002-2005, has an 8.2-liter cooling system capacity, a figure consistent with a smaller displacement inline-four that requires less coolant volume to maintain operating temperatures.
  • Both engine configurations share an identical coolant change interval of 240,000 km under normal use conditions, placing the service interval in the long-life category typically associated with modern extended-life coolant formulations.
  • The 3.4 V6 spans the full 1999-2005 model range covered by the specifications, while the 2.2 16V entered the lineup later, from 2002-2005, meaning the V6 was the sole engine option for the first three years of the listed period.
  • A 240,000 km change interval on both configurations indicates the use of a long-life coolant type, as conventional coolants are generally rated for significantly shorter intervals, often in the range of 50,000 to 100,000 km.
