Product Description

Genuine Mopar Thermostat 52028898AJ is an OEM engine-cooling component designed to regulate coolant flow and maintain the engine at its proper operating temperature. This thermostat is specified at 195°F and is supplied with a seal. Mopar lists 52028898AE and 52028898AI as superseded/replaced part numbers for 52028898AJ.

The thermostat controls the circulation of engine coolant between the engine and radiator. When the engine is cold, the thermostat remains closed to help the engine reach operating temperature efficiently. As coolant temperature rises, the thermostat opens and allows coolant to circulate through the radiator, helping maintain stable engine temperature and prevent overheating.

The 203°F calibration is designed around the factory cooling-system requirements for applicable Mopar engines. Using the correct OEM thermostat helps maintain proper engine warm-up, coolant circulation, and temperature control. 

Compatible Engine Applications

Catalog information lists this thermostat for numerous 5.7L HEMI V8 applications, as well as certain 6.1L, 6.2L, and 6.4L HEMI/SRT V8 engines. Exact compatibility depends on the vehicle year, model, engine configuration, and production date.

Restore proper engine temperature control with the Genuine Mopar 52028898AJ Thermostat. This OEM thermostat is engineered to regulate coolant flow through the engine cooling system and maintain the factory-specified operating temperature. Rated at 203°F and supplied with a sealing component, it is designed for a direct-fit installation on select Chrysler, Dodge, Jeep, and Ram vehicles equipped with compatible HEMI V8 engines. The 52028898AJ replaces previous Mopar thermostat part numbers 52028898AE and 52028898AI. Always verify fitment by vehicle year, model, engine, production date, and VIN before purchase.
