250cc Thermostat - 158°F (70°C) for 172mm for Scooters & Mopeds

250cc Thermostat Assembly for 172mm 4-Stroke Engines

This thermostat assembly is built for 250cc 4-stroke liquid-cooled engines and helps keep the engine at a steady working temperature. It begins to open at 158°F (70°C), which assists in preventing overheating and supports a longer engine life. As one part of the cooling system for scooters, it is suited to a range of scooters and mopeds.

Features and Benefits

This unit is a direct substitute for the factory thermostat in many common engine models. Its exact opening temperature helps the engine stay within an efficient temperature range. Keeping temperatures in check reduces the risk of rapid engine failure and expensive repairs.

Installation and Compatibility

This thermostat is designed for a simple fit and takes the place of the original unit in engines such as the VOG 260 and BN169MM. Before installing, look over nearby parts like the coolant hoses and radiator cap for signs of wear. Refilling the cooling system with fresh coolant after flushing can help remove trapped air and improve how the system performs.
