Product Description

Keep your engine running at the correct operating temperature with the Arrowhead Thermostat 87°C, designed for precise cooling control in select Jeep and Mercedes-Benz models. This thermostat regulates coolant flow, helping your vehicle warm up efficiently and preventing overheating during operation. The robust cast aluminium housing includes integrated hose connections and a two-pin electrical connector for temperature control, ensuring reliable performance in demanding conditions.

This thermostat is suitable for various Jeep and Mercedes-Benz vehicles, including models equipped with engines such as the OM612 and OM646. Always confirm your vehicle’s model, year, engine size, and engine code before ordering to ensure compatibility.
