Product Description

This Arrowhead Thermostat 89°C is designed for the cooling system of select Renault vehicles, helping to regulate engine temperature for optimal performance. It features an integrated housing with a gasket and multiple hose connections, ensuring a secure fit and effective coolant flow management. The unit includes a four-pin electrical connector, which supports precise temperature control and integration with your vehicle's electronic systems.

Fitment is specific to certain Renault models, notably the Clio III 1.4 and 1.6, and Megane 1.4 from 2002 to 2011. Always confirm your model, year, engine size, and engine code before ordering to ensure compatibility and avoid installation issues.

Common symptoms of a failing thermostat include engine overheating, slow engine warm-up, erratic temperature gauge readings, poor heater performance, and coolant leaks around the housing. You may also notice increased fuel consumption or the engine running too cool, which can impact efficiency and emissions.

If you experience any of these issues, it is important to inspect and replace your thermostat promptly. A faulty thermostat can lead to further engine damage, so address symptoms early to maintain reliable vehicle operation.
