  Seal Ring, Thermostat Gasket, Ring Adjusting

• Description:

  This is a genuine Ford thermostat sealing ring, a consumable rubber seal that Ford dealer catalogs list as a Ring, also described as an adjusting ring, used to seal the thermostat to its housing or the engine. It seats in a machined groove and is compressed when the housing is assembled, forming a leak-tight seal that keeps coolant contained and maintains correct cooling system pressure and flow around the thermostat. This is a single-use consumable seal: it should be replaced rather than reused whenever the thermostat or housing is removed, because a compressed or aged ring will not seal reliably a second time. You will find it used on Ford applications including Fiesta, Focus, and EcoSport fitted with the 1.0L EcoBoost engine, and it appears in the thermostat assembly diagram as the sealing ring supplied with the unit, with applications spanning a broad range of model years. These are representative examples rather than a complete list. A worn, cracked, or improperly seated sealing ring causes a coolant leak at the thermostat, which can lead to low coolant level, overheating, visible weeping or dripping, and a low-coolant warning. Because it is an inexpensive consumable that protects against costly overheating damage, it is standard practice to fit a new seal during any thermostat service. Confirm the correct seal for your specific vehicle and engine against your VIN before ordering, since cooling system seals vary by application.
