PROCEDURE TO ADJUST THE SUBARU SUPER COOLANT CONCENTRATION

CAUTIONUse the SUBARU Super Coolant with a 50 - 60% concentration in order to obtain maximum antifreeze and anti-rust performance.

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 (concentrated type) until it reaches the proper dilution.
