Dorman redesigned this assembly in aluminum with patent-pending internal improvements to better manage heat transfer and coolant routing, helping reduce the chance of future coolant loss and return visits. This assembly is sold as an OE FIX replacement and intended to fit directly in place of the factory part — always confirm fitment by entering your vehicle details in the fitment (garage) tool before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this aluminum housing improve reliability under the hood?\u003c\/h3\u003e\n\u003cp\u003eReplacing a plastic housing with a corrosion-resistant aluminum unit addresses two common failure points: material degradation from prolonged heat exposure and bleeder valve wear. The metal construction resists warping and cracking, which reduces the likelihood of sudden coolant leaks that can cause engine overheating. The upgraded design also helps maintain a consistent mating surface for a reliable seal.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum body withstands higher underhood temperatures than the original plastic\u003c\/li\u003e\n  \u003cli\u003eMore consistent sealing surface reduces leak potential at the coolant outlet\u003c\/li\u003e\n  \u003cli\u003eRobust construction minimizes repeat replacements and maintenance visits\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat performance benefits come from the patent-pending internal design?\u003c\/h3\u003e\n\u003cp\u003eThe internal geometry has been reworked to improve coolant circulation and heat transfer through the housing, which supports the engine’s cooling system efficiency. While it isn’t a performance-modification part, better flow dynamics can help the cooling system manage temperature spikes more effectively. These design changes were validated through product testing and engineering review.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOptimized coolant flow paths reduce turbulence at the outlet\u003c\/li\u003e\n  \u003cli\u003eImproved heat transfer characteristics compared with the original design\u003c\/li\u003e\n  \u003cli\u003eEngineered and tested by Dorman product engineers in the U.S.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this Dorman assembly directly replace my vehicle’s original part?\u003c\/h3\u003e\n\u003cp\u003eThis thermostat housing assembly is made to match the function and mounting points of the factory water outlet for specified model years of Chrysler 300, Dodge Challenger, and Dodge Charger.

Avoid over-tightening the bleeder valve and use a fresh seal or gasket if supplied. After installation, refill the cooling system and bleed air according to the vehicle manufacturer’s procedure, then inspect for leaks during a controlled warm-up.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUse correct torque values and a new gasket or seal where applicable\u003c\/li\u003e\n  \u003cli\u003eProperly bleed the cooling system to remove trapped air\u003c\/li\u003e\n  \u003cli\u003eInspect and test for leaks after reaching operating temperature\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: This Dorman 902-3035HP thermostat housing assembly is aimed at owners and technicians who want a longer-lasting replacement for the vulnerable plastic water outlet on select Chrysler 300, Dodge Challenger, and Dodge Charger vehicles. It’s appropriate for routine repairs, preventative upgrades during cooling system service, and for shops seeking an OE FIX solution that reduces the chance of repeat failures.
