Saturn Relay (USA / CAN)

Coolant capacity & service interval

Saturn Relay (USA / CAN) coolant capacity ranges from 10,2 to 12,2 liters. Service intervals include a 12 month check and a 240000 km or 60 month change. The data covers 3 configurations.

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

Additional Notes

  • The Saturn Relay 3.5 V6 carries a base cooling system capacity of 10.7 liters when equipped with front air conditioning, rising to 12.2 liters when rear air conditioning is also present. The 1.5-liter difference reflects the additional coolant volume required to serve the rear climate circuit.
  • On the 3.9 V6 configurations covering 2006-2008, the base cooling system capacity is 10.2 liters, which is slightly lower than the 3.5 V6 baseline figure of 10.7 liters despite the larger displacement engine.
  • The rear air conditioning option adds 1.4 liters to the 3.9 V6 cooling system, bringing total capacity to 11.6 liters. The same rear air conditioning addition on the 3.5 V6 adds 1.5 liters, reaching 12.2 liters.
  • Both the 3.9 V6 FWD and the 3.9 V6 AWD share identical cooling system capacities of 10.2 liters base and 11.6 liters with rear air conditioning, indicating the AWD drivetrain does not alter coolant volume requirements for the 2006-2007 period.
  • The coolant change interval is 240,000 km or 60 months across all three configurations. The 60-month figure equals five years, which is consistent with extended-life coolant formulations commonly used in systems of this era.
  • The 3.5 V6 specifications include a coolant check interval of 12 months in addition to the change interval. A separate check interval at 12 months means the coolant condition and level are to be inspected annually between full drain-and-fill services.
