Frequently Asked Questions
What is Dexcool Coolant?
Dexcool Coolant, also known as Dex-Cool, is a type of antifreeze coolant developed by General Motors (GM) for use in vehicles. Introduced in 1995, Dexcool is a long-life coolant designed to provide improved corrosion protection and freeze protection for up to 150,000 miles or 6 years. It’s a silicate-based coolant that’s formulated to provide a higher level of protection against corrosion and freeze damage than traditional ethylene glycol-based coolants. Dexcool Coolant is also designed to be more environmentally friendly and has a lower toxicity level than other coolants.
How does Dexcool Coolant work?
Dexcool Coolant works by preventing the engine’s cooling system from freezing in cold temperatures and from overheating in hot temperatures. It does this by lowering the freezing point of the coolant mixture and raising the boiling point. The silicate-based formula in Dexcool Coolant also helps to prevent corrosion and wear on engine components, which can lead to engine failure. Additionally, Dexcool Coolant is designed to be a self-sealing coolant, meaning that it can repair small leaks and prevent coolant from leaking out of the system.
Why should I use Dexcool Coolant?
You should use Dexcool Coolant if you want a long-lasting, high-performance coolant that provides excellent protection against corrosion and freeze damage. Dexcool Coolant is designed to last longer than traditional coolants, which means you’ll need to change it less often. This can save you money and reduce waste.
