Questions

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.
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.
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.
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.
