Zerex Dex-Cool Antifreeze/Coolant is proven to maximize engine life in passenger cars and light trucks, and is approved for use in GM, Ford, Chrysler and SAAB vehicles with cooling systems that require an orange antifreeze with Organic Acid Technology (OAT). Specially formulated with a patented carboxylate solution, Zerex is made for your car and protects better than industry standards against corrosion, leaking, deposits as well as freezing and boiling.

Zerex OAT formula is silicate and phosphate-free. It protects from corrosion, scale and rust, so radiators, water pumps and other metal cooling system parts (including aluminum) stay clean and your antifreeze flows and functions properly. Zerex Dex-Cool Antifreeze/Coolant does not contain amines, borates, nitrates or nitrites. So whether you’re topping off your radiator or doing a complete system flush, trust Zerex Dex-Cool Antifreeze/Coolant.

• UNSURPASSED FREEZE PROTECTION AND ANTI-BOIL PERFORMANCE outperforms industry standards
• ORGANIC ACID TECHNOLOGY RESISTS RUST, SCALE & CORROSION while protecting all cooling system metals (including aluminum)
• HIGH-QUALITY ADDITIVES PROTECT AGAINST LEAKS and won’t harm gaskets, hoses, plastics or original vehicle finish
• PREDILUTED ORANGE FORMULA IS READY-TO-USE in a 50/50 ratio with deionized water to protect all modern engine components from winter freezing (-34F) and summer boiling (265F).
• ORANGE CONCENTRATE FORMULA should be mixed with clean tap water or demineralized water at 50/50 ratio for temperatures -34 to 265F; 60/40 for -62 to 270F; and 70/30 for -84 to 267F
• 5 YEAR/150,000 MILE GUARANTEE protects against engine failure caused by freeze-ups or boil-overs
• BATCH-TESTED IN THE LAB, FLEET-TESTED IN THE REAL WORLD to help car and truck owners achieve optimal performance and maximize engine life.

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
