Product Description

The Cooltec THERMOSTAT 90°C is designed to regulate engine temperature by controlling coolant flow within your vehicle’s cooling system. This thermostat is a key component in maintaining optimal engine operating conditions, helping to prevent overheating and ensuring efficient performance. With a precise 90°C opening temperature, it plays a crucial role in the cooling circuit of select BMW and Mercedes-Benz models.

This thermostat is compatible with various BMW and Mercedes-Benz vehicles. However, fitment can vary depending on the model, year, engine size, and engine code. Always double-check your vehicle’s specifications before ordering to ensure proper compatibility.
