CAUTION:
When using an alternative engine coolant, follow the instructions of the engine coolant for its maintenance cycle, freezing concentration, etc.
1. PROCEDURE TO ADJUST THE SUPER COOLANT CONCENTRATION
CAUTION:
SUBARU SUPER COOLANT concentration must be used from 50 to 60% to assure the best performance of the anti-freeze and anti-rust agents.
To adjust the concentration of SUBARU SUPER COOLANT according to temperature, find the proper SUBARU SUPER COOLANT concentration in the table, and add diluting water to the SUBARU SUPER COOLANT (undiluted type) until it reaches the proper dilution.
