The original coolant thermostat housing assembly on certain Chrysler and Dodge vehicles is made from plastic that becomes brittle over time, eventually leading to cracks. In addition, overtightening the bleeder valve can cause fluid leaks that can damage the cooling system. This Dorman OE FIX thermostat housing assembly is manufactured from corrosion-resistant aluminum to provide increased coolant system protection, and features patent-pending design upgrades that optimize coolant flow and heat transfer.

Product Features:

• Upgraded replacement - this coolant thermostat housing assembly is made of aluminum and is able to withstand under hood temperatures better than the original plastic assembly
• Increases reliability - corrosion-resistant aluminum design reduces future maintenance costs and provides increased cooling system protection
• Patent-pending design - engineered to optimize coolant flow and heat transfer, tested and backed by a team of product experts in the United States and more than a century of automotive experience
• Application specific - made to directly match the function and fit of the original engine coolant water outlet on specified Chrysler and Dodge vehicles
