Impreza WRX STI F4-2.5L Turbo (2008)
Coolant: Fluid Type Specifications
Coolant Type
WRX STI vehicles are filled at the factory with SUBARU Super Coolant that does not require the first change for 11 years/137,500 miles (11
years/220,000km). This coolant should not be mixed with any other brand or type of coolant during this period. Mixing with a different coolant will
reduce the life of the coolant. Should it be necessary to top up the coolant in your WRX STI for any reason, use only SUBARU Super Coolant. If the
SUBARU Super Coolant is diluted with another brand or type, the maintenance interval is shortened to that of the mixing coolant.
Do not splash the engine coolant over painted parts. The alcohol
contained in the engine coolant may damage the paint surface.
