Subaru Impreza, GJ, GP (EU)

Additional Notes

• The Subaru Impreza GJ/GP (EU) 1.6i cooling system holds between 8.1 and 8.6 liters across all listed model years from 2013-2016, covering both AWD and FWD configurations. The range between the lower and upper values reflects normal variation between a service drain-and-fill and a full system overhaul capacity.
• The 2.0i engine carries a slightly different coolant capacity of 7.7-8.5 liters, a range that is both lower at the minimum and lower at the maximum compared to the 1.6i. The wider spread in the 2.0i range suggests greater variability between partial and full system fills for that engine.
• All configurations across both engine sizes share a coolant check interval of every 30,000 km or 24 months, whichever comes first. This interval applies uniformly regardless of drivetrain layout or model year within the 2012-2016 range.
• Under normal use conditions, the coolant change interval for all listed configurations is 120,000 km or 72 months. At that interval, 72 months equals six years, placing the change on a relatively long service cycle by general automotive standards.
• The initial service condition carries a significantly extended coolant change interval of 220,000 km or 132 months. The 132-month figure equals eleven years, reflecting the extended service life of factory-fill coolant formulations that are typically long-life or super-long-life types used at the point of manufacture.
• The gap between the normal change interval of 120,000 km and the initial service interval of 220,000 km represents a difference of 100,000 km. Once the factory fill has been replaced under the initial service schedule, subsequent changes revert to the standard 120,000 km or 72-month cycle.
• The 1.6i FWD variants for 2013-2014 and 2015-2016 share identical capacity figures and service intervals with the AWD 1.6i variants of the same years. The drivetrain difference has no effect on cooling system specifications in these configurations.
