Detailed Description

This Motorad Kit thermostat housing assembly is engineered for cooling-system service where accurate temperature regulation matters. The 5003KTFS uses a copper case and wax compound to react quickly as coolant temperature changes, while the OE-specified 195°F rating supports factory-style engine warm-up and operating temperature control. Its housing construction combines steel, stainless steel, copper, and rubber for a service-ready replacement in demanding cooling systems.

Compatible With select Ford Crown Victoria, Ford Grand Marquis, Mercury Grand Marquis, and Lincoln Town Car applications across 1993-2004 model years. This part cross-references 95003KTFS for the same application.

What It Helps Address

• Engine running cooler or hotter than the specified thermostat temperature
• Coolant temperature instability during normal driving
• Housing wear or corrosion at the thermostat mounting point
• Service replacement needs on OE-style cooling system assemblies
• Temperature control concerns in high-demand cooling systems

Installation Notes

Verify engine application, model year, and OE temperature specification before installation. The housing uses two bolt holes and includes a jiggle pin; gasket or seal is not listed as included in the attributes, so confirm sealing components separately if needed. Clean the mating surfaces thoroughly and inspect the cooling system for contamination or trapped air before refilling.
