Cat® Coolant Conditioner for Aluminum Components is designed to passivate reactive aluminum surfaces within the cooling system, helping to prevent unwanted chemical reactions that can compromise performance. It is intended as a one-time treatment for systems containing aluminum components and has been rigorously tested and approved by Caterpillar to meet the same high standards as all Genuine Cat® Parts. By effectively inhibiting reactions that lead to nitrite depletion in extended life coolants, this conditioner helps maintain coolant integrity and system reliability over time.
