Dorman Engine Coolant Thermostat Housing Assembly — Direct-Fit for Dodge & Jeep 2011–2018, Heat-Resistant

This replacement thermostat housing assembly is built to match OE fitment and withstand rapid temperature swings common to cooling systems, helping maintain proper coolant flow and sealing. It’s manufactured by Dorman, a long-established aftermarket supplier, and is intended for specific Dodge Durango and Jeep Grand Cherokee and Wrangler model years. Before ordering, use the vehicle selector to confirm compatibility with your exact trim and year.

Will this thermostat housing fit my vehicle?

Fitment depends on vehicle year, make, and trim. This Dorman 902-852 is made to replace the factory water outlet on listed models, but you should verify compatibility using the site’s garage tool and the Confirmed Fit indicator.

• Compatible models include Dodge Durango (2011–2015), Jeep Grand Cherokee (2011–2015), Jeep Wrangler JK (2018), and Jeep Wrangler (2012–2017).
• Enter your vehicle trim in the garage tool to confirm fitment before purchase.
• If an “i” icon appears, hover to review additional fitment notes to ensure correct match.

How does this assembly stand up to engine heat and cycles?

Dorman engineered this housing to resist cracking and leaking through repeated heating and cooling cycles. Materials and design focus on durability so the part endures thermal stress commonly seen in cooling systems.

• Constructed for temperature resistance to reduce failure from thermal expansion and contraction.
• Sealing surfaces and outlets designed to minimize coolant leaks under operating conditions.
• Professional aftermarket design intended to meet or exceed typical service life expectations.

What should I expect when replacing the original housing?

Installers can expect a direct-replacement part engineered to match the original housing’s mounting points and coolant passages. Using this assembly should simplify installation compared with sourcing a non-matching aftermarket part.

• Direct-replacement design aligns with factory bolt locations and hose connections.
• Reduces the need for modification or extra adapters during installation.
• Helps restore intended coolant routing and thermostat operation when fitted correctly.

Are there any maintenance or inspection tips when replacing the housing?

When installing a new thermostat housing, inspect surrounding components for wear and replace gaskets and hoses as needed to ensure a reliable seal. Proper torque on fasteners and clean mating surfaces prevent leaks after installation.

• Clean mating surfaces and replace any old gaskets or O-rings to ensure a tight seal.
• Check adjacent hoses, clamps, and thermostat condition; replace if brittle or corroded.
• Follow manufacturer torque specs and pressure-test the cooling system after installation.

Who is this for: The Dorman 902-852 thermostat housing assembly is aimed at vehicle owners, DIY mechanics, and professional service shops needing a reliable, direct-fit replacement for specific Dodge and Jeep models. It suits anyone replacing a cracked or leaking water outlet or performing cooling-system maintenance who wants a part engineered for durability and correct fit. Always confirm your vehicle’s trim and year in the fitment tool before purchase to ensure proper compatibility.
