Coolant / Antifreeze Says a lot about Cooling System Health!

Routinely inspect your Coolant / Antifreeze with these simple checks, and flush the system when necessary, to help prolong the life of your Cooling System:

COOLANT COLOR / CLARITY
Coolant should be bright, clear and free of debris. Dirty or brown coolant can be caused by: A blown Cylinder Head Gasket Corrosion from imbalanced coolant chemistry Oil in Coolant

COOLANT CONDITION
Use Coolant / Antifreeze Test Strips to test condition / chemistry. Poor coolant condition can be caused by: Frequently topping off with water Improper dilution / mixing coolant formulas Test Strip Process

COOLANT VOLTAGE
Use an Electrical Tester to Test Coolant for Electrolysis. Common causes of Electrolysis include: Stray electrical current from a loose or damaged Battery Cable ground Worn / old, acidic coolant A reading of 0.4 volts or above suggests electrolysis
