BDFHYK Aluminium Coolant Thermostat Housing Assembly for Chrysler/Dodge 3.6L V6 (2011–2022) — OE Fit, Crack‑Resistant

BDFHYK 902-3035 is an upgraded aluminium coolant thermostat housing assembly designed to replace OE units on 3.6L V6 Chrysler 300 and Dodge Challenger/Charger models from 2011–2022.

This replacement thermostat housing is built from a robust aluminum alloy to resist cracking and heat-related deformation common to plastic housings. It directly replaces OE numbers 5184977AD, 5184977AE and related references, and fits the 3.6L V6 engine platform used across late-model Chrysler and Dodge sedans and coupes. The assembly controls coolant routing to help the engine reach and maintain its optimal operating temperature.

How does this thermostat housing affect engine cooling performance?

The housing directs coolant between the engine and radiator and holds the thermostat that opens and closes with temperature changes. A properly functioning housing ensures consistent coolant flow and helps the cooling system respond predictably under load and at idle.

• Maintains correct coolant routing to the radiator and bypass circuits.
• Seals the thermostat to prevent leaks that reduce cooling efficiency.
• Aluminum construction resists warping from repeated heat cycles.

Will this replace my factory part directly?

This BDFHYK assembly is made to match OEM fitment for the specified models and OE part numbers, enabling straightforward replacement without modification in most cases. Always confirm compatibility with your vehicle’s model year, engine code and OEM part number before ordering.

• Compatible with Chrysler 300 and Dodge Challenger/Charger 2011–2022, 3.6L V6.
• Cross-references OE numbers 902-3035HP, 5184977AD, 5184977AE and related codes.
• Designed for bolt-on installation using existing gaskets and mounting points.

What advantages does the aluminium upgrade offer over plastic housings?

Aluminum reduces the risk of cracking from heat cycling and gives greater dimensional stability where seal surfaces and thermostat seats must remain precise. That durability helps prevent coolant leaks and repeated repairs.

• Higher structural strength than common plastic housings.
• Improved resistance to heat-related deformation and stress fractures.
• Longer service life under normal driving conditions.

How should I inspect and maintain the replacement assembly after installation?

After installing the new housing, check for coolant leaks and proper thermostat operation during warm-up. Periodic visual inspections during routine service help catch gasket failures, hose clamp issues or corrosion before they cause overheating.

• Verify coolant level and pressure after bleeding air from the system.
• Inspect mating surfaces and fasteners for proper torque and seal integrity.
• Look for signs of corrosion, gasket age, or hose clamp slippage at intervals.

Who this part is for: If you own a 2011–2022 Chrysler 300 or a 2011–2022 Dodge Challenger or Charger equipped with the 3.6L V6 and you need a durable replacement for a cracked, leaking, or degraded thermostat housing, this BDFHYK aluminium assembly is engineered to be a direct-fit, longer-lasting alternative to plastic OE housings. It’s aimed at DIY mechanics and professional shops seeking an OE-referenced replacement that improves reliability and minimizes repeat repairs. Confirm fit by checking your vehicle’s model, engine, and OE part number before purchase. BDFHYK provides replacement support if any quality issues arise.
