Keep your cooling system sealed and coolant flowing with the Dorman engine coolant thermostat housing (P/N 902-3001), a part also listed as an engine coolant filler neck. It drops in as a direct-fit replacement on the listed applications, including the 2000 Chrysler Cirrus, 2000-2002 Chrysler Neon, 2000-2005 Dodge Neon, 2000 Dodge Stratus, 2003-2005 Dodge SX 2.0, 2000 Plymouth Breeze and 2000-2001 Plymouth Neon.

This part houses the thermostat and serves as the coolant connection point, routing coolant between the engine and radiator; a cracked or leaking housing lets coolant escape and can lead to overheating. If a failed housing is the cause of your leak, this part replaces it.

  • Direct replacement: engineered to match the fit and durability of the stock housing on the listed vehicles.
  • Durable construction: designed to withstand extreme temperature changes and resist cracking and leaking.
  • Cost-effective: offers manufacturer-level quality at a lower cost than a dealer replacement.
  • Engineered design: professionally developed by an aftermarket leader in replacement thermostat housings.

Note: this item is listed under both names — engine coolant filler neck and engine coolant thermostat housing.
