Motorad 4909KTFS Engine Coolant Thermostat Housing Assembly

Thermostat Housing Assembly Overview

Motorad 4909KTFS is an engine coolant thermostat housing assembly built to OE specifications for a wide range of classic Dodge, Chrysler, and Plymouth applications. It combines the housing, thermostat, and gasket in one service part for cooling system repairs that need a direct-fit replacement.

Key Features

• OE supplier manufacturing with OEM-quality materials and processes.
• 192°F thermostat rating for temperature control in the cooling system.
• Steel, stainless steel, copper, and paper construction for the housing and sealing components.
• Paper gasket/seal material with one outlet port and two bolt holes.
• Black and silver finish with a 2.13 in flange diameter and 1.54 in outlet diameter.

Detailed Description

This Motorad thermostat housing assembly is engineered for vehicles that require a 192°F thermostat and an OE-specified housing design. The copper case and wax compound are used to respond quickly to coolant temperature changes, helping the engine reach and maintain the intended operating range. Part number 4909KTFS is a practical choice for service work on Dodge B150, D150, and Ramcharger applications, as well as Chrysler and Plymouth models listed in the fitment data. This part cross-references Monroe Shocks & Struts (e.g., 94909KTFS) for the same application.

What It Helps Address

• Coolant temperature control that is no longer staying within the specified range.
• Housing wear or sealing issues at the thermostat mounting point.
• Thermostat replacement needs during cooling system service.
• Leak concerns related to an aged gasket or sealing surface.
• Fitment concerns on older Dodge, Chrysler, and Plymouth cooling system repairs.

Installation Notes and Tips

Verify the 192°F temperature specification before installation. Confirm the flange diameter, outlet diameter, and bolt-hole layout against the original part, and replace the gasket during service. Fitment includes many classic Dodge, Chrysler, and Plymouth models; examples include Fits 1981-1992 Dodge B250, N/A, Fits 1979-1991 Dodge D150, N/A, and Fits 1978-1981 Chrysler Town & Country, N/A. Part number 4909KTFS should be matched to the vehicle’s cooling system requirements before installation.

Quality Assurance

Motorad manufactures this assembly to OEM specifications and processes using OE-supplier standards and materials. The design is built for demanding automotive cooling systems and uses a copper case with wax compound for responsive temperature control.
