EVIL ENERGY Thermostat Housing Assembly for 3.6L Dodge Durango & Jeep (2011–2020) Complete Kit with Thermostat

Why does a replacement thermostat housing matter?

How will replacing the housing affect engine warm-up and performance?

Installing a proper thermostat housing and thermostat helps the engine reach and hold optimal operating temperature more predictably. That reduces prolonged cold running, which can cause higher wear and less efficient combustion until the engine warms up.

• Thermostat opens at approximately 203°F for correct coolant flow timing.
• New gasket prevents coolant leaks at the mating surface.
• OEM-fit plastic housing aligns with factory coolant passages.

Which vehicles and part numbers does this assembly replace?

This assembly is built to fit a broad set of 3.6L V6 Chrysler applications, matching several OE references so it bolts in with minimal modification. It covers popular model years for Dodge Durango and Jeep Grand Cherokee and Wrangler.

• Compatible models: 2011–2015 Dodge Durango 3.6L.
• Also fits 2011–2020 Jeep Grand Cherokee and 2012–2017 Jeep Wrangler 3.6L (including 2018 JK).
• Replaces OE numbers such as 902-852, 49569, 5184651AF and related references.

What comes in the box and how does it simplify installation?

The kit includes every part you typically need to swap the thermostat housing, minimizing trips to the parts store. A pre-matched thermostat and dedicated gasket cut down installation time and help ensure a leak-free seal.

• Includes: thermostat, rubber gasket, plastic housing and a pair of nitrile gloves.
• Pre-assembled fitment points match factory mounting locations.
• Simplifies routine coolant system maintenance or cooling-system repairs.

How durable and reliable is the replacement housing?

The housing is molded from automotive-grade plastic engineered for coolant exposure and repeated thermal cycles. While no part lasts forever, a new housing reduces the chance of leak-related failures associated with aged or cracked factory units.

• Plastic housing built for engine coolant environment and temperature swings.
• New rubber gasket resists compression set and coolant seepage.
• Thermostat calibrated to specified opening temperature for consistent operation.

Who is this for: This EVIL ENERGY thermostat housing assembly is intended for DIY mechanics, independent shops and fleet maintenance technicians working on 3.6L Chrysler‑family engines who need a complete replacement kit. It’s especially useful when the original housing is cracked, leaking, or when replacing the thermostat during cooling system service. Confirm vehicle year and engine code before purchase to ensure fitment.
