Proper coolant maintenance keeps your engine running efficiently, reduces wear on components, and supports long-term vehicle health.

Why Coolant Service Is Important

Coolant (or antifreeze) absorbs and dissipates heat from the engine while preventing freezing in cold temperatures. Over time, coolant can become contaminated, lose its protective properties, or accumulate deposits that reduce efficiency. Regular service ensures that your cooling system functions correctly, preventing overheating, corrosion, and potential engine damage.
