OEM stands for original equipment manufacturer. Traditionally, it is a company whose products are used as components in the products of another company.
Use the EasyMatch tool to find the antifreeze/coolant that’s compatible with your car. We also always recommend that you consult your owners manual to ensure you are using the correct fluid. If you have further questions, please contact us.
Yes. OEM Antifreeze/Coolant is fully compatible with other similarly formulated HOAT/OAT coolants. For best results, do not mix with conventional high pH, borate or silicate based coolants.
Concentrate is straight coolant that must be diluted prior to use. Ready-to-use is pre-mixed 50% coolant to 50% water that can be used directly from the bottle.
For extreme temperatures, mixing a concentrate coolant with deionized water is the better option because maximum freeze protection of -64 °C/-83 °F can be achieved with a 70/30 mix (coolant to water). It is also best used when completing a system flush. Since residual water always remains in the system even after a flush, the ready-to-use premixed coolant is great for top-ups. Because you don’t have to mix it with water and can use it straight from the bottle, ready-to-use is also convenient.
Straight coolant concentrate will freeze. The freeze point of undiluted coolant will only be 8.6 °F (-13 ºC), causing you to have potential freeze point problems in the wintertime. Also, too much corrosion inhibitor could lead to inhibitor fallout, especially in those cases where SCAs (supplemental coolant additives) are added. Always dilute coolant concentrate with deionized water prior to use. If you would like to use coolant straight from the bottle without having to dilute, choose our 50/50 pre-diluted formulation.
Our OEM Extended Life Antifreeze/Coolant is an Organic Acid Technology (OAT) engine coolant. It is an engine coolant that is based on fully neutralized organic acid corrosion inhibitors. These corrosion inhibitors last longer than traditional corrosion inhibitors, and this is why OAT coolants are typically long life products. These coolants do not contain phosphates, borates, silicates, etc.
In general, follow your OEM’s (Original Equipment Manufacturer) guidelines. If you do not have a guide and are using traditional coolant, then change every two years. Extended Life Antifreeze/Coolant should be changed every 5 years or 250,000 km.
It is important to note that you should check your coolant system at least twice a year. If the coolant is dirty, cloudy, or full of particulate, then the coolant system should be drained, flushed, cleaned, and refilled with a prediluted good quality coolant and the reason for the poor condition of the coolant should be determined.
If the product is still in the original sealed container or has not been diluted with water then it has a shelf life of many years.
OEM understands there’s a lot to know about maintaining your vehicle’s cooling system. Choosing the right antifreeze/coolant for your particular vehicle is a great start.
