The current Genuine Mitsubishi thermostat for the earlier Gen 3 trucks with the smaller petrol V6, and the number that replaced the one this catalogue lists as superseded — the chain is on this page. It matters which of the two Gen 3 thermostats you order: the earlier and later trucks use different parts that open at different temperatures, and the catalogue gives a figure for each, so match the part to your engine rather than to the word "Montero". The specialist selling it recommends genuine units only and is unusually emphatic about it. The number, the fitment and the count come from the Montero specialist's own catalogue page, cited below — a parts catalogue is good evidence for what a part number is and what it fits, and it is not factory literature, so read every figure on this page as the catalogue's claim rather than as a service-manual specification.
