Product Details

The Motorad Standard line focuses on OE-style replacement cooling components built for factory-level fit and function. Part number 724-203 uses OEM-quality materials and safety standards as supplied by an OE supplier, with a copper case and wax element that reacts quickly to coolant temperature changes. The result is a thermostat designed for stable engine warm-up and consistent operating temperature in vehicles that specify a 203°F thermostat.

This part cross-references Dayco 72403 and Wix 57243 for the same application. Search terms such as 2011-2014 Dodge Charger thermostat, 2012-2014 Jeep Wrangler thermostat, and 2014 Ram ProMaster 1500 coolant thermostat all point to the same OE-spec service part when the vehicle calls for this temperature rating.

What It Helps Address

• Engine running too cool or too warm
• Delayed warm-up after cold starts
• Temperature fluctuation in the cooling system
• Thermostat replacement during cooling system service
• OE-spec repair on vehicles requiring a 203°F thermostat

Installation Notes

Verify the housing style and temperature specification before installation. The included O-ring seal should be seated cleanly, and the mating surfaces should be free of old gasket material and corrosion. Use the installation tool as needed to position the thermostat insert correctly, and follow the vehicle service procedure for coolant refill and air bleeding.
