Product Description

The Cooltec Expansion Tank is a crucial component in your vehicle's cooling system, designed to safely contain and manage coolant as it expands and contracts during engine operation. This cooling water bottle serves as a reservoir, helping to maintain the correct coolant level and pressure to prevent overheating and engine damage. Its durable plastic construction and secure screw cap help ensure reliable performance under varying temperature conditions.

This part is specifically compatible with select Kia models. It is important to check your vehicle’s model, year, engine size, and engine code to ensure correct fitment before ordering. The expansion tank is engineered to fit into the existing cooling system, integrating with your vehicle’s hoses and mounting points.

Common symptoms of a failing expansion tank include visible coolant leaks, frequent low coolant warnings, engine overheating, or cracks and discolouration on the tank itself. You may also notice steam from the engine bay or a sweet smell from leaking coolant. If the tank’s cap is not sealing properly, you might experience pressure loss or bubbling in the coolant.

If you notice any of these symptoms, the expansion tank should be inspected and replaced as soon as possible to avoid further cooling system issues. Always ensure the replacement matches your car’s specifications for a proper seal and function.
