Frequently Asked Questions

FAQs General Questions:

Why is it important to mix antifreeze with water?
Antifreeze contains chemicals that protect your engine against rust and corrosion, as well as freeze and boil protection. Water is required to activate the chemicals in the inhibitor package. Furthermore, adding water to antifreeze actually increases the freeze and boil protection provided. For example, a mix of 40% antifreeze and 60% water provides freeze protection down to -10°F and boil protection up to 259°F. In comparison, a mix of 70% antifreeze and 30% water provides freeze protection down to -62°F and boil protection up to 270°F. However, we do not recommend adding more than 70% antifreeze. This would limit the corrosion and freeze protection and heat transfer capabilities of the antifreeze.

Can I mix ordinary tap water with antifreeze?
Yes, tap water is commonly used for mixing with antifreeze, however, deionized water or distilled water is preferred. Do not use water softened with salts to mix with antifreeze.

Why does my vehicle owner’s manual recommend a phosphate free antifreeze?
Some European car manufacturers recommend that phosphate free antifreeze be used in their vehicles. The reason is that the water in Europe has an extremely high mineral content. If you mixed an antifreeze containing phosphates, which are part of the corrosion inhibitor package, with the water they have in Europe, the phosphates in the antifreeze may “drop out” and form deposits in your cooling system that can lead to overheating and corrosion. However, this is not a major concern in North America, since our water is lower in mineral content, or softer, than European water. If you are interested in a phosphate-free antifreeze, Old World Industries offers PEAK™ Global LifeTime™ Antifreeze, PEAK Long Life Antifreeze, and SIERRA®, the Safer Antifreeze.

Typically extended life coolants have a longer shelf life. How should I dispose of used antifreeze?
All laws and regulations should be observed when disposing of Antifreeze/Coolant and Radiator Fluids. Call the EPA or the office of your state or local environment agency for details on disposal procedures. Generally places that sell antifreeze will accept used coolants.

What is the proper mixture of antifreeze to water for adequate freeze protection in my area?
While temperatures and climates vary, most vehicles can use our conventional antifreeze protection chart:

PEAK Global Questions:

What is PEAK™ Global LifeTime™ Antifreeze & Coolant?
PEAK Global LifeTime Antifreeze & Coolant features a patented, advanced organic acid technology that provides guaranteed LifeTime protection – for as long as you own your vehicle!* Its patented inhibitors will provide maximum protection against damaging rust and corrosion in all automobiles and light trucks worldwide, regardless of make, model, year or original antifreeze color. * See warranties

What is an Organic Acid Technology (OAT) coolant and how is it different than conventional coolants?
Conventional antifreeze is formulated with inhibitors composed of neutralized inorganic acids, such as phosphates and silicates, to protect a cooling system against rust and corrosion. Over time, however, inorganic inhibitors deplete and may no longer provide maximum cooling system protection. This is why it is generally recommended that conventional coolants be changed every 2 years or 24,000 miles. In contrast. OAT coolants are formulated with neutralized organic acids to form a highly effective corrosion inhibitor system that provides maximum cooling system protection. Organic inhibitors do not deplete as quickly as the inorganic inhibitors used in conventional coolants. This is why properly formulated OAT coolants typically provide up to 150,000 miles or 5 years of cooling system protection between service intervals. The superior OAT formula in PEAK Global LifeTime uniquely provides a LifeTime of cooling system protection – for as long as you own your vehicle.

Are all extended life OAT coolants the same?
No. There are hundreds of organic acids that can be used as corrosion inhibitors in extended life coolants. PEAK Global LifeTime Antifreeze uses a unique and patented inhibitor package to provide maximum cooling system protection and is the first extended life coolant that can be used in all automobiles worldwide.

Why is PEAK Global LifeTime Antifreeze & Coolant Amber in color?
Today there is a rainbow of automotive coolant colors. You may even be unsure of your vehicle’s current antifreeze color. Because PEAK Global LifeTime Antifreeze is the first antifreeze specifically formulated for use in all makes and models, the unique amber color will not change the color of your antifreeze when used to top off the cooling system. So if your antifreeze is already green, it will stay green, or orange, or yellow or blue … When you flush, drain and refill your cooling system with PEAK Global LifeTime Antifreeze, the unique amber color let’s you know your automobile is provided with maximum cooling system protection. PEAK Global LifeTime Antifreeze is the solution to the color confusion.

Is PEAK Global LifeTime Antifreeze & Coolant compatible with other brands of extended life antifreeze?
Yes. PEAK Global LifeTime Antifreeze’s unique and patented technology is fully compatible with and can be used to top-off other extended life coolants including General Motor’s DEX-COOL and the new and old Ford and Chrysler extended life coolants. However, to realize the guaranteed LifeTime of cooling system protection provided by PEAKGlobal LifeTime Antifreeze, a complete cooling system flush and fill is required. My owner’s manual instructs me to use a particular brand of antifreeze/coolant.

Will my new car warranty automatically be voided if I use an aftermarket antifreeze/coolant that is different than the antifreeze/coolant brand identified by the manufacturer?
No. Federal Law, the Magnuson-Moss Warranty Act, prohibits a manufacturer or dealer from voiding your warranty just because you have chosen to use an aftermarket antifreeze/coolant in your automobile.

What is the Magnuson-Moss Warranty Act?
It is a federal law passed in 1975 that assures that consumers receive accurate warranty information and that prohibits manufacturers, dealers and others from improperly and unjustly denying warranty coverage to consumers.

Can I use PEAK Global LifeTime Antifreeze & Coolant in my GM, Ford or Chrysler automobile?
Yes. PEAK Global LifeTime Antifreeze is recommended for use in all automobiles and light duty trucks worldwide, regardless of make, model or year made. In fact, the patented inhibitor technology provided in PEAK Global LifeTime Antifreeze has been used to provide maximum rust and corrosion protection for cooling systems in millions of GM, Ford and Chrysler automobiles around the world.

Can I use PEAK Global LifeTime Antifreeze & Coolant in European and Asian manufactured automobiles?
Yes. PEAK Global LifeTime Antifreeze features an advanced patented technology that provides maximum rust and corrosion protection for cooling systems found in European and Asian automobiles. Additionally, the patented technology found in PEAK Global LifeTime Antifreeze meets the silicate-free coolant requirements of Asian car manufacturers and the phosphate-free requirements of European car manufacturers.

Wipers Questions:

How often should I change my wiper blades?
Depending on their use and climate they should be changed preferably once or twice a year.

Do I need to do anything special when I go through a car wash?
Yes. After the car wash, make sure you remove any wax that is on the windshield for best quality wiping.

Can I use any type cleaner on my windshield?
No. Use only non-abrasive cleaners and those cleaners that are not petroleum based.

Aren’t all blades the same?
No. Many other blades are made from plastic, which can crack. PEAK Wiper Blades are all metal and can withstand the harshest weather conditions.

Does PEAK offer refills?
No. PEAK Wiper Blades are only offered as a replacement blade assembly. Are both the blades on my car the same size?

It depends on the make, model and year of your vehicle. Sometimes they are the same size while other times they are not. Consult your owners manual or the catalog when purchasing replacement blades to make sure you purchase the correct size blades.
