This direct‑fit thermostat housing assembly replaces the factory original plastic unit for Dodge Durango, Jeep Grand Cherokee and Jeep Wrangler equipped with 3.6L Pentastar V6 engine.

Original plastic housings are prone to aging and cracking under repeated hot‑cold cycling, which triggers coolant leaks, unstable temperature readings and potential engine overheating risk. Pre‑assembled with built‑in thermostat and sealing gasket, this unit matches original mounting hole positions and hose port layout for simple bolt‑on replacement without modification. It precisely manages coolant circulation to keep engine operating within factory‑specified temperature range, lowering mechanical wear and carbon accumulation.

Please double‑check your OE part number, vehicle year and engine configuration before ordering to guarantee correct fitment

How to Replace A Thermostat Housing On Your Vehicle?

6‑step thermostat housing installation guide diagram

Replacing your thermostat housing is a critical cooling‑system repair job. We highly recommend hiring a professional certified mechanic to complete this installation. Improper installation may lead to coolant leaks, air pockets inside your cooling system, or dangerous engine overheating.

Follow these general reference steps for thermostat housing replacement:

  1. Cool the engine completely before starting any work.
  2. Drain a portion of engine coolant into a suitable container.
  3. Loosen and disconnect the radiator hose clamp.
  4. Remove your original worn‑out thermostat housing assembly.
  5. Mount and secure the brand‑new thermostat housing.
  6. Refill coolant to the correct level inside the reservoir.

After installation, run the engine and check for leaks. Always dispose of old coolant according to local environmental regulations.

FAQS

Q: Will this thermostat housing fit my Dodge Durango, Jeep Grand Cherokee, or Jeep Wrangler?

A: Confirmed applications are 2011–2015 Dodge Durango 3.6L, 2011–2015 Jeep Grand Cherokee 3.6L, 2012–2017 Jeep Wrangler 3.6L, and 2018 Wrangler JK 3.6L. Do not order for a 2016–2020 Grand Cherokee or 2018 Wrangler JL by year and engine alone, because later 3.6L Pentastar versions may use a different housing, such as 4893926AH. Match the original OE number or verify by VIN before ordering.

Q: Which OE numbers does this assembly replace, and what does it include?

A: This assembly replaces 5184651AF, 5184651AG, 5184651AH, and 5184655AD, with aftermarket references 49569, 823203, and 85944. It combines a plastic thermostat housing, thermostat, and sealing gasket, with a specified opening temperature of 203°F/95°C. Mounting bolts are not listed as included, so retain the original serviceable hardware unless replacements are supplied.

Q: What symptoms indicate a failing thermostat housing or thermostat on the 3.6L Pentastar?

A: Housing failure can cause coolant around the housing or upper radiator hose connection, dried coolant residue, a sweet smell, repeated coolant loss, or overheating. A thermostat stuck open may cause slow warm-up, weak cabin heat, low operating temperature, and code P0128. A stuck-closed thermostat may cause rapid overheating, but low coolant, trapped air, a faulty water pump, radiator, cooling fan, or temperature sensor can produce similar symptoms.

Q: Will replacing this assembly fix a P0128 code or every overheating problem?

A: It may correct P0128 when the thermostat is stuck open or opening at the wrong temperature, and it may stop coolant loss caused by a cracked or leaking housing. It will not repair unrelated cooling-system faults. Check coolant level, scan-data temperature, housing leakage, and cooling-system pressure before replacement; if the engine is overheating, stop driving and allow it to cool completely.

Q: How should this thermostat housing be installed and the cooling system refilled?

A: Work only on a cold engine. Drain the coolant below the housing, remove the necessary intake components and upper radiator hose, unbolt the old housing, clean the mating surface, and install the new assembly with its gasket using the factory torque specification. Refill and bleed the system through the proper bleed point or vacuum-fill procedure. Early applications such as 2011–2012 generally specify HOAT coolant, while later vehicles generally specify OAT coolant meeting MS.90032; follow the exact owner’s manual and never mix HOAT and OAT: 2011 Grand Cherokee manual, 2015 Durango manual

Q: How long should the thermostat housing last, and how can I prevent another failure?

A: There is no fixed replacement interval; service life depends on coolant condition, heat cycles, previous overheating, system pressure, installation torque, and correct bleeding. The six-month product warranty is not an expected service-life rating.

Check coolant protection and the entire cooling system at least annually, inspect the housing and hose connection for residue, and pressure-test the system if repeated coolant additions are required.
