                                 2880513 (gallon)


                Recommended Coolant
                Use only high quality antifreeze/coolant mixed with
                distilled water in a 50/50 or 60/40 ratio, depending on
                freeze protection required in your area.
                                                                     2. The pressure cap relief pressure is 13 psi. Replace
                                    CAUTION                             cap if it does not meet this specification.
                   Using tap water in the cooling system will lead to a
                 buildup of deposits which may restrict coolant flow and
                  reduce heat dissipation, resulting in possible engine
                 damage. Polaris Premium 60/40 Antifreeze/Coolant is
                recommended for use in all cooling systems and comes
                              pre-mixed, ready to use.
