Will this thermostat housing fit my Chrysler 300, Dodge Charger, or Challenger?

Yes — the part is made to fit vehicles equipped with the 3.6L Pentastar V6 engine across the specified model years. Verify your engine size (3.6L) and model year range before purchase to ensure compatibility with factory coolant plumbing and sensor locations.

• Compatible vehicles: Chrysler 300 3.6 (2011–2023).

• Confirm engine displacement and model year on your VIN or under-hood sticker.

How does this replacement housing affect coolant system reliability?

Replacing a cracked or leaking housing helps restore proper coolant containment and circulation, reducing the risk of loss of coolant and related engine temperature issues. The part is shaped and drilled to accept original hoses and sensor fittings, which helps maintain a secure, leak-resistant connection when installed correctly.

• Direct-fit mounting aligns with factory bolt holes to minimize installation adjustments.
• Designed for original hose diameters to prevent pinch or gap leaks.
• Accommodates factory coolant sensors and fittings for full system function.

What should I expect during installation and basic maintenance?

Installation typically requires basic hand tools, draining some coolant, and replacing gaskets or O-rings as needed. Tighten fasteners to factory torque specs, refill the cooling system with manufacturer-recommended coolant, and bleed air pockets to ensure consistent flow and accurate temperature readings.

• Common tools: sockets, torque wrench, drain pan, and coolant funnel.
• Replace seals and clamps during reassembly for the best leak protection.
• Post-installation: run engine to operating temperature and inspect for drips.

Are sensor ports and hose connections the same as the original part?

The MOTOKU housing is manufactured to match the OEM layout of ports and hose spigots so sensors and hoses can be reattached without modification. That alignment helps maintain proper sensor readings and prevents hose interference with nearby engine components.

• Sensor bosses are positioned to receive factory temperature senders or switches.
• Hose spigots match stock diameters to accept original clamps and lines.
• No special adapters are typically required for installation.

Who this is for: This thermostat housing is aimed at DIY mechanics, independent repair shops, and owners of Chrysler 300, Dodge Charger, or Challenger vehicles with the 3.6L Pentastar V6 who need a reliable, direct-fit replacement for a damaged or leaking housing. If you want to restore proper coolant routing without modifying factory plumbing, or you’re doing routine cooling-system maintenance, this part is built to step in where the original housing is no longer sealing correctly.
