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 and fits many vehicles, among them the 2000-2005 Dodge Neon, 2003-2005 Dodge SX 2.0 and 2000 Dodge Stratus; see the Buyer's Guide tab for the full list.
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.
