Detailed Description

Calorstat TH5753.84J is an engine coolant thermostat designed for Jaguar cooling system service where stable operating temperature is important. The thermostat begins opening at 183°F, helping regulate coolant flow through the radiator once the engine reaches the specified temperature range. This part includes a gasket O-ring seal, which supports a proper sealing surface during thermostat replacement. The compact flange dimensions and standard design make TH5753.84J a practical replacement for vehicles calling for this temperature specification. This part cross-references Stant 14748 for the same application.
