Antifreeze
What is Antifreeze?
Antifreeze, also known as coolant, is an essential fluid that prolongs machine life by keeping car and truck engine systems from overheating. Antifreeze is typically made from a combination of water and ethylene glycol (C2H602). The proper antifreeze will provide superior heat transfer for engines, while offering protection against cavitation and corrosion, to ensure your engine can run smoothly for longer periods of time.

How does Antifreeze work?
Ideal Boiling & Freezing Points
To maintain a cooling system's ideal temperature, antifreeze is pumped through the engine and heater core of your vehicle, simultaneously lowering the freezing point and raising the boiling point of the engine's water and fluid.
Prevents Engine Damage
In cooler climates, antifreeze prevents water in the engine from freezing and damaging essential engine parts. Antifreeze coolant alleviates engine stressors, such as overheating and cracking caused by higher air temperatures and combustion heat created in the engine core itself.
More Advanced Than H2O
Using water as engine coolant is common, but not recommended - especially in winter months. Since water expands upon freezing, the extra pressure causes engine damage. Adding more water only furthers the problem. Antifreeze dilutes the water and prevents it from freezing.
Which Antifreeze should I purchase?
Different engines have different antifreeze requirements, so choosing the proper antifreeze for your vehicle can be tough. This is because certain antifreeze only work under specific conditions. Let's evaluate the options.
