ADJUSTMENT

CAUTION:

When using the equivalent engine coolant, follow the instruction from the engine coolant for the 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 concentration.
