BDFHYK Aluminum Coolant Thermostat Housing Assembly for Chrysler 300 & Dodge Charger/Challenger 3.6L (2011–2022) — Direct-Fit, Cor

The BDFHYK 902-3035 is an upgraded aluminum coolant thermostat housing assembly designed to replace worn or cracked housings on 3.6L V6 Chrysler 300 and Dodge Challenger/Charger models from 2011–2022.

If your vehicle is showing overheating symptoms, coolant leaks around the thermostat area, or you want a longer-lasting replacement than stock plastic housings, this assembly is engineered as a direct-fit, durable alternative. It matches common OEM part numbers and installs where the factory thermostat and housing sit, helping restore proper coolant flow control without major modification.

How does this thermostat housing restore proper engine temperature control?

The housing secures the thermostat and connects coolant passages to the radiator hose, so it directly affects when coolant flows through the cooling system. A solid, correctly sealing housing ensures the thermostat can open and close reliably and prevents coolant loss at the connection points.

• Direct-fit for 3.6L V6 Chrysler 300 and Dodge Charger/Challenger 2011–2022.
• Replaces OEM numbers including 5184977AD/AE/AG/AH, 902-3035, 824-203, and others.
• Precision ports align with factory coolant passages for leak-free installation.
• Facilitates correct thermostat operation to maintain ideal engine temp.

Why choose an aluminum housing instead of the original plastic version?

Aluminum resists cracking and deforming under heat cycles better than many plastics used in original equipment. Choosing an aluminum assembly reduces the chance of repeat failures, especially in vehicles with higher mileage or repeated thermostat work.

• Durable aluminum alloy construction for improved longevity.
• Better heat dissipation and resistance to warping over time.
• Lower risk of brittle fractures that cause coolant leaks.
• Corrosion-resistant finish to withstand coolant and road conditions.

Which vehicles and part numbers is this compatible with?

This housing is built to work with the 3.6L V6 used in specific Chrysler and Dodge models from model years 2011 through 2022. Verify fitment by matching the listed OE numbers or confirming model, sub-model, and engine code before purchase.

• Compatible models: Chrysler 300 (2011–2022), Dodge Challenger and Charger (2011–2022).
• Engine fitment: 3.6L V6 only.
• Cross-references: 902-3035HP, 5184977AD/AE/AG/AH, 824-203, 85943, 34776.
• Always confirm fit by OE number or vehicle VIN where possible.

Is the assembly easy to install and what should I expect during replacement?

Installation is typically straightforward for anyone familiar with basic engine cooling system work and common hand tools. Expect to drain some coolant, remove hoses and the old housing, swap the thermostat if needed, and torque the new unit to factory specifications.

• Simple bolt-on replacement—uses factory mounting points and hoses.
• Recommended to replace thermostat gasket or O-ring and refill coolant.
• Check for leaks and proper thermostat operation after bleeding the system.
• Professional installation recommended if you lack cooling-system experience.
