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 Coolant
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

  • Stray electrical current from a loose or damaged Battery Cable ground
  • Worn / old, acidic coolant
