Coolant

The Subaru Genuine Coolant containing antifreeze and anti-rust agents is especially made for Subaru engine, which has an aluminum crankcase. Always use Subaru Genuine Coolant or equivalent: a mixture of 50% soft water and 50% ethylene-glycol coolant.

To prevent cooling system leaks, always add Genuine Subaru cooling system Conditioner (Part No. SOA635071) whenever the coolant is replaced.
