Prestone Radiator Complete Care contains an inhibitor package that coats and helps protect key cooling system metals from corrosion. This product can be added to antifreeze/coolants between changes to boost the depleted corrosion protection of these fluids.
When used according to package directions, this specially formulated product will not cause over-addition problems such as reduced heat transfer or inhibitor precipitation that can be detrimental to the antifreeze in the system.
