Product Description

This Cooltec expansion tank with cap is designed for the cooling system of select Renault vehicles. The expansion tank, also known as a cooling water bottle, is an essential component that stores excess coolant and helps maintain the correct pressure within your engine's cooling system. Its translucent plastic construction allows for easy monitoring of coolant levels, while the moulded cap area provides a secure seal to prevent leaks. Multiple hose connections and sturdy mounting tabs ensure reliable integration into your Renault's engine bay.

This expansion tank is compatible with various Renault models, including certain Megane, Scenic III, Fluence, and RS, TCe, dCi, and 16V engine variants. Always confirm your vehicle's model, year, engine size, and engine code before ordering to ensure correct fitment.

Common signs of a faulty expansion tank include visible coolant leaks, frequent low coolant warnings, overheating, cracks or discolouration in the plastic, and a sweet smell from the engine bay. You may also notice erratic temperature gauge readings or visible steam when the engine is hot.

It is important to replace a damaged or leaking expansion tank promptly to prevent coolant loss and potential engine overheating. Always inspect the tank and cap during routine maintenance, and replace them if you spot any wear, cracks, or compromised seals.
