Coolants are made to be an additive which lowers the freezing point of a water-based liquid, a different mix may be best for a different function. We carry a full stock of antifreeze and coolants for just about every application. If there is something specific you are looking for, let us know and if we don't carry it, we can help in locating it for you. We carry three main types of antifreeze coolant:
• 50/50 Premixed Extended Life Antifreeze
• Extended Life Diesel Engine Coolant
• Universal Antifreeze
Below is a list of the products we carry and a brief description of each product, as some of the antifreezes are better used for specific functions. An "antifreeze" mixture is used to obtain that goal. When mixed correctly, it can achieve lowering the freezing point in cold environments and also achieves boiling point elevation to allow higher coolant temperature.
