COOLING SYSTEM TECH FACTS – Coolant Charts

Coolant Charts

Penray recommends that all cooling system tests be performed using Penray’s Universal 3-Way Test Strips. Penray also recommends using Fleetcharge® or DDC PowerCool® Antifreeze for conventional coolant.

*For your convenience, Penray carries refractometers (part # AR-102) and pre-printed adjustment charts. Always refer to the maintenance manual for the vehicle before making any changes to the cooling system

If you have any questions, please feel free to contact us at any time.
