Dorman Coolant Thermostat Housing Water Outlet for Dodge Durango & Jeep Wrangler — Aluminum OE FIX

The Dorman 902-852XD is an aluminum replacement coolant thermostat housing (water outlet) designed to replace brittle OEM plastic units on select Dodge Durango and Jeep Grand Cherokee/ Wrangler models for improved durability and leak resistance.

Many original coolant outlets for certain Dodge and Jeep SUVs were molded from plastic and can crack, warp, or leak as they age or when the bleeder valve is overtightened. Dorman’s OE FIX 902-852XD replaces that plastic assembly with a rugged aluminum housing engineered to match factory fit and function while offering greater long-term reliability under underhood heat and pressure. Before ordering, confirm compatibility by entering your vehicle trim into the garage tool and checking the Confirmed Fit indicator.

How does this aluminum outlet improve durability compared to the original plastic part?

Aluminum resists the heat-induced embrittlement and stress-cracking that plastic housings often develop over time. The metal construction reduces the chance of warping and helps maintain sealing surfaces under repeated thermal cycles.

• Aluminum construction for higher temperature tolerance and strength
• Reduced risk of cracks and leaks from aging or overtightened bleeder valves
• Longer service life compared to factory plastic assemblies

Will this Dorman part fit my Dodge Durango or Jeep model?

The 902-852XD is made to directly match the form and function of the original thermostat housing on specific model years listed for Dodge Durango, Jeep Grand Cherokee, and Jeep Wrangler vehicles. Fitment can vary by engine and trim, so vehicle verification is important.

• Compatible model years include select 2011–2015 Durango and Grand Cherokee, and select 2012–2018 Wrangler years
• Use the garage tool to enter your vehicle trim and confirm the Confirmed Fit bar
• Hover over the blue “i” icon for any special fitment notes that apply to your vehicle

What are the practical installation and performance benefits?

Because the Dorman OE FIX unit matches OEM mounting points and hose connections, installation is straightforward for most technicians and experienced DIYers. The improved material reduces the chance of future coolant loss and the associated overheating or component corrosion that can follow a leak.

• Direct-replacement design for straightforward installation
• Durable sealing surfaces help prevent coolant leaks and repeat repairs
• Backed by Dorman product experts and decades of automotive aftermarket experience

Are there any special care or verification steps before ordering?

Confirming fitment and inspecting surrounding cooling components before installation helps avoid surprises. If your vehicle shows any signs of coolant contamination or warped mating surfaces, address those issues when replacing the outlet.

• Enter vehicle trim in the garage tool and check the Confirmed Fit bar
• Verify fitment notes by hovering the blue “i” if present
• Inspect thermostat, hoses, and mating surfaces during replacement to ensure a proper seal

Who this is for: The Dorman 902-852XD is intended for owners and technicians working on compatible Dodge Durango, Jeep Grand Cherokee, and Jeep Wrangler SUVs who want a robust, longer-lasting replacement for a failing OEM plastic coolant outlet. It’s a practical choice if you’ve experienced cracks, leaks, or repeated failures with the stock housing and prefer a metal replacement engineered to match the vehicle’s original fit and function.
