Product Overview

Protect your engine from the risks of overheating with this High-Precision Water Temperature Sensor. Specifically engineered for 250cc water-cooled engines, this switch acts as the "brain" of your cooling system, automatically triggering the radiator fan when temperatures reach 88°C. By maintaining the engine within its optimal thermal range, it ensures consistent power delivery and prevents costly damage to the cylinder head and gaskets.

Product Compatibility

A direct replacement for the thermal switch found on classic 250cc liquid-cooled horizontal engines.
