Scion iQ (USA / CAN)

Coolant capacity & service interval

Scion iQ (USA / CAN) coolant capacity ranges from 2,1 to 4,9 liters. Service intervals include checks at 8000 km or 15000 miles/18 months, and changes at 80000 km, 160000 km, 50000 miles/60 months, or 100000 miles/120 months. The data covers 10 configurations.

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

Additional Notes

  • The Scion iQ 1.3 (NGJ10) carries a cooling system capacity of 4.9 liters across all model years and both the USA and CAN markets, a figure consistent with a full service fill of a small-displacement inline-four engine.
  • The iQ EV (KPJ10) has a notably smaller cooling system capacity of 2.1 liters, reflecting the reduced thermal management demands of an electric drivetrain compared to the 1.3-liter combustion engine variant.
  • For the iQ 1.3 in the Canadian market, coolant checks are scheduled at 8,000 km intervals, while the standard change interval under normal use conditions is set at 80,000 km.
  • Under a first change only condition, the Canadian-market iQ 1.3 extends the coolant change interval to 160,000 km, which is double the normal use interval of 80,000 km. First change only designates a single extended service life for the factory-fill coolant before reverting to the standard interval.
  • In the USA market, the iQ 1.3 coolant check interval is expressed as 15,000 miles or 18 months, whichever comes first, with a normal use change interval of 50,000 miles or 60 months.
  • The USA-market first change only interval for the iQ 1.3 doubles the normal change interval to 100,000 miles or 120 months, mirroring the same proportional extension seen in the Canadian market specifications.
  • The iQ EV (KPJ10) shares the same USA-market check and change intervals as the iQ 1.3, with checks at 15,000 miles or 18 months, a normal change at 50,000 miles or 60 months, and a first change only interval of 100,000 miles or 120 months, despite the significant difference in system capacity.
  • The coolant service intervals for the iQ 1.3 NGJ10 are identical between the 2012 and 2013-2015 model year groups in both the USA and CAN markets, with capacity remaining at 4.9 liters throughout.
