Detailed Application Overview

Motorad 5178KTFS is a direct-fit thermostat housing assembly for cooling system repair on 1993-1997 Chrysler Concorde, 1993-1997 Chrysler Intrepid, 1994-1997 Chrysler LHS, 1993-1997 Dodge Intrepid, 1997 Plymouth Prowler, and 1994-1996 Chrysler New Yorker. It is engineered for vehicles that require a 195°F thermostat setting and OE-specified housing configuration. If you are replacing a worn thermostat housing on a Chrysler Concorde or Dodge Intrepid, this part number provides the correct temperature control and housing layout for the listed applications.

Common Issues This Part Can Address

• Coolant temperature that stays too low or runs outside the OE target range
• Cracked, warped, or corroded thermostat housing surfaces
• Coolant seepage at the housing-to-engine sealing area
• Erratic thermostat response caused by worn internal components
• Air trapped in the cooling system after thermostat service

Installation Notes and Tips

Verify engine code and cooling system configuration against the vehicle listing before installation. Clean the mating surfaces thoroughly, inspect the outlet and flange areas for corrosion, and replace any damaged sealing surfaces before assembly. Use the included gasket and seal specified in the fitment notes, and refill and bleed the cooling system carefully so the jiggle pin can help purge trapped air.
