About this kind of part (general, written by SearchForPart)

Opens to send coolant to the radiator when the engine is warm. Overheating or an engine that stays cold points to a stuck thermostat. Check the opening temperature and size.

When ordering, give the part number exactly as printed and its maker, and the make, model and year of the truck, trailer, reefer unit or machine (or the engine or unit serial number). SearchForPart shows fitment only as the source printed it: check it before you order.
