FAQ

Open FAQ Does the color of antifreeze matter? Can you mix antifreeze with different colored antifreeze products?

Does the color of antifreeze matter? Can you mix antifreeze with different colored antifreeze products?

Color is used by many antifreeze and vehicle manufacturers for identification purposes. Color has no bearing on the performance of the antifreeze. Always follow the specifications in your owner's manual for coolant applications.

Open FAQ How Does Engine Coolant Work?

How Does Engine Coolant Work?

Engine coolant is mixed with water, usually at a 50/50 ratio, and poured into the proper reservoir in your engine. The chemical ethylene glycol is used as a base to create a liquid that is pumped through your car’s engine to regulate and maintain an optimal operating temperature during extreme hot or cold weather conditions.

Open FAQ What Makes Each Antifreeze Type Different?

What Makes Each Antifreeze Type Different?

All coolant is made up of the base chemical ethylene glycol. Whether it's green, pink or orange, they are all the same at their base. For instance, what makes Multi-Vehicle Antifreeze/Coolant different from ZEREX™ Original Green is additives and dyes that are designed for use in higher-mileage vehicle types, whereas Original Green is a more general formula used worldwide for decades.

Open FAQ How Often Does My Car Need New Coolant?

How Often Does My Car Need New Coolant?

Most fluids your vehicle needs should be drained and replaced at various intervals in order to be effective. The same goes for your coolant. At least twice a year you should check your coolant levels—before the summer heat and before the winter cold. Consult your vehicle’s owner's manual for more precise information on when to flush and replace the coolant in your vehicle.
