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 QM (part number 124790-49800).

A genuine original part, despatched from our Melbourne warehouse, with GST included in the price.

30-day no-fuss returns. If you opened the box and the part doesn't fit, send it back unused within 30 days for a full refund. We'll cover return freight on our error; you'll cover it if the part was correct as ordered.

12-month warranty. Manufacturing defects covered for 12 months from purchase date. Wear-and-tear (impellers degrade with use — that's their job) is not covered, but reach out if something fails early and we'll work it out with the manufacturer.

Australian Consumer Law applies in addition to the warranty above.
