It's important to change anti-freeze/coolant regularly in your car.
IMPROVE THE LIFE OF THE COOLANT SYSTEM COMPONENTS IN YOUR CAR
As you drive, additives in the coolant are consumed and cause the coolant to wear out. Eventually the coolant will become acidic and start to cause corrosion, thus reducing the life of your system.
IMPROVE THE OPERATING EFFICIENCY OF YOUR VEHICLE Regular coolant changes are an inexpensive way to maintain your engine cooling and passenger compartment heating systems.
HELP MAINTAIN YOUR VEHICLE’S WARRANTY COVERAGE Whether you lease or own your vehicle, coolant exchange is part of your vehicle’s recommended maintenance program, and it is required maintenance to retain related warranty coverage
HOW IS THE COOLANT CHANGED? Your service provider will use O.E. approved equipment to add new coolant while the old coolant is removed. This process ensures that virtually all of the old fluid and contaminates are removed and replaced with clean fluid.
HOW OFTEN SHOULD THE COOLANT BE CHANGED? Car manufacturers recommend coolant changes at various intervals based upon a combination of driving habits and mileage. Check your owner’s manual or ask your service provider for the recommended intervals. Certain tests can also determine the need for a change of fluid. Color alone has NOT been shown to be a reliable indicator of the need for coolant change.
