EVIL ENERGY Thermostat Housing Assembly for 3.6L V6 Dodge Durango & Jeep Grand Cherokee/Wrangler — Complete Kit with Thermostat &

EVIL ENERGY Thermostat Housing Assembly is a complete coolant thermostat kit that replaces worn housings and thermostats on 3.6L V6 Dodge and Jeep models, restoring proper engine warm-up and coolant flow control.

This thermostat housing assembly is an aftermarket replacement engineered to fit 3.6L V6 Chrysler engines used in Dodge Durango (2011–2015), Jeep Grand Cherokee (2011–2020) and Jeep Wrangler (2012–2017, including 2018 JK). The kit includes the plastic housing, a pre-set thermostat, a new rubber gasket and nitrile gloves so you have the basic parts needed for a routine cooling‑system repair. It replaces several OE part numbers used across factory catalogs, making it a direct-fit option for common coolant-housing failures.

Why replace the thermostat housing on my 3.6L engine?

Thermostat housings and thermostats wear over time, crack, or leak, which can cause incorrect coolant routing and irregular engine warm-up times. Replacing the assembly restores a sealed connection between the engine and radiator circuit and ensures the thermostat opens at its designed temperature. Using a matched kit reduces installation steps and helps avoid repeated visits.

• Includes the housing, thermostat, gasket, and gloves for one-repair convenience
• Opens at approximately 203°F (engine operating threshold)
• Replaces OE numbers such as 902-852, 49569, 5184651AF and related references
• Direct-fit design for specific 3.6L V6 models to simplify installation

How does this assembly help with coolant leaks and overheating concerns?

The assembly provides a new sealing surface and a functional thermostat that controls coolant flow. A compromised housing can leak or fail to route coolant properly; installing the replacement restores the intended behavior of the cooling circuit without modifying other components. Proper installation helps the engine reach and maintain correct operating temperature.

• New rubber gasket creates a fresh seal to prevent coolant seepage
• Thermostat calibrated for correct opening temperature (≈203°F)
• Plastic housing designed for OEM-compatible fit and alignment
• Reduces the chance of uncontrolled coolant flow while the engine warms

Will this part fit my vehicle and which part numbers does it replace?

Check your vehicle's year, engine size and existing OE number to confirm compatibility: this kit is made for 3.6L V6 engines in specified Dodge and Jeep model years. The assembly is offered as a replacement for several factory part numbers, covering common OE references to simplify sourcing.

• Compatible models: Dodge Durango (2011–2015), Jeep Grand Cherokee (2011–2020), Jeep Wrangler (2012–2017, incl. 2018 JK)
• Replaces OE references like 902-852, 49569, 823203, 85944 and 5184651AF/AG/AH/655AD variants
• Intended for 3.6L V6 engine families only—verify engine code before ordering
• Sold as a single complete kit for one repair job

What comes in the box and what should I expect when installing it?

The kit is packaged with the parts needed for a typical thermostat housing replacement so you can perform the swap with minimal additional purchases. Basic hand tools and coolant capture are required, and replacing the thermostat housing typically involves draining some coolant, removing hoses and fasteners, and cleaning mating surfaces before assembly.

• Package contains: thermostat (pre-set), rubber gasket, plastic housing, and nitrile gloves
• Expect to drain part of the cooling system and replace the drained fluid per manufacturer specs
• Use proper torque on bolts and ensure gasket surfaces are clean for leak-free sealing
• Recommended to verify thermostat orientation and check for hose clamp condition during install

Who is this for: This EVIL ENERGY thermostat housing assembly is aimed at DIY mechanics, independent shops and fleet technicians servicing 3.6L Dodge and Jeep vehicles that need a direct-fit replacement for a leaking or failed thermostat housing. It’s suitable when you want a complete, ready-to-install kit that matches common OE numbers and restores proper coolant control without sourcing multiple individual parts.
