Product Description

The Cooltec Expansion Tank is an essential component within your vehicle's cooling system, designed to safely store excess coolant and manage pressure as your engine heats and cools. This expansion tank, also known as a cooling water bottle, helps maintain the correct coolant level and prevents overheating by allowing coolant to expand and contract as temperatures fluctuate.

While this part is typically associated with Hyundai H100 models, compatibility may vary due to limited fitment data. Always verify your vehicle's model, year, engine size, and engine code before ordering to ensure a proper fit.

Common signs that your expansion tank may need replacement include visible cracks or leaks, low coolant levels without obvious loss elsewhere, overheating, or steam from the engine bay. You might also notice warning lights for the cooling system or a sweet smell from leaking coolant.

If you experience any of these symptoms, it is important to inspect the expansion tank for damage or degradation. Replacing a faulty tank promptly helps prevent more serious engine issues and costly repairs.

MiMi Auto Parts offers reliable cooling solutions and delivers nationwide across South Africa. Trust us to supply the right part for your vehicle and keep your engine running smoothly.
