Yanmar Thermostat

Regulates engine operating temperature, opening to let cooling water flow once the engine is warm. A stuck thermostat causes over- or under-cooling — renew it (with its seal) when servicing the cooling system.

This is the genuine Yanmar Thermostat, GM, FWC* (part number 121750-49800).

Supplied brand-new and despatched from our Melbourne warehouse. Prices include GST.
