Dorman Engine Coolant Water Outlet (Thermostat Housing) Aluminum Replacement for Chrysler/Dodge/Jeep/Ram/VW — 902-3036XD, OE FIX D

The Dorman 902-3036XD is an aluminum replacement engine coolant water outlet (thermostat housing) engineered to replace brittle plastic housings and restore dependable coolant flow on select Chrysler, Dodge, Jeep, Ram and Volkswagen models.

Original plastic thermostat housings can crack with age and heat exposure, and overtightened bleeder valves may lead to leaks that compromise your cooling system. Dorman's OE FIX design swaps the fragile plastic for a durable aluminum assembly, with engineered flow features that improve heat transfer and reduce the chance of repeat failures. This product is built to match the original mounting and hose locations for a straightforward swap on specified vehicle years and trims—always confirm fit with the vehicle lookup tool before buying.

How does the aluminum housing compare to the original plastic unit?

Aluminum resists the heat and chemical exposure found in engine bays better than older plastic housings, which can become brittle and crack over time. This Dorman assembly uses a heavier-duty material and incorporates flow-optimized passages to reduce stress points and improve coolant circulation without changing service procedures.

• Aluminum construction reduces risk of heat-related fractures.
• Patented internal geometry designed to enhance coolant flow and heat transfer.
• Manufactured and tested by Dorman product teams in the U.S.
• Drop-in replacement intended to match original mounting points and hose connections.

What installation considerations should I know?

Installation follows standard thermostat housing replacement steps: drain coolant, remove hoses and fasteners, swap the housing and reinstall with proper torque. Because this is an OE FIX part designed for specific applications, you should still verify that hose orientations and bleeder locations match your vehicle before final assembly.

• Drain coolant and relieve pressure before beginning work.
• Use recommended torque specs—avoid overtightening bleeder valves to prevent leaks.
• Replace gaskets or seals as required; inspect hoses for wear while accessible.
• Refill coolant and bleed the system following manufacturer directions.

What durability and performance benefits can I expect?

The upgraded material and patented design features aim to lower the chance of future coolant leaks and thermal damage compared with the factory plastic housing. While no part can guarantee a lifetime of service, the aluminum assembly is intended to be a longer-lasting option that reduces the likelihood of repeat repairs on the same component.

• Improved resistance to underhood heat and vibration.
• Engineered passages promote steady coolant circulation and heat transfer.
• Potential to reduce future maintenance related to coolant leaks or cracked housings.

Who is this for: The Dorman 902-3036XD suits vehicle owners, mechanics and fleet managers who need a tougher replacement for a failed factory thermostat housing on compatible Chrysler, Dodge, Jeep, Ram or VW models. It's especially helpful when the original plastic outlet has cracked, is leaking, or you want an OE FIX upgrade engineered for improved durability. Always confirm vehicle fitment with the garage tool before ordering to ensure correct application.
