Thermostat

The Perkins Thermostat (OEM 054/2485613) is a replacement engine cooling-system component designed to regulate coolant temperature in compatible Perkins diesel engines. It controls the flow of coolant through the engine as operating temperature changes, helping the engine reach and maintain its normal working temperature. Perkins parts information identifies the corresponding 2485613 thermostat as an 82°C unit with a 54 mm main diameter and integrated jiggle pin.

Designed for reliable operation within the engine cooling system, the thermostat helps prevent both over-cooling and excessive operating temperatures. The 2485613 specification is used across a range of Perkins engines, including selected 4.212, 4.236, 4.248, 6.354 and 1004/1006 applications, making it suitable for a variety of construction, agricultural and industrial equipment.

FUNCTION AND OPERATION

• Regulates engine coolant flow according to temperature
• Helps the engine reach its correct operating temperature efficiently
• Opens at approximately 82°C to allow increased coolant circulation
• Helps prevent excessive engine temperature during normal operation
• Supports stable engine performance and efficient combustion

IMPORTANT INFORMATION

The thermostat is a temperature-control component within the cooling system and should be replaced if it is sticking, failing to open at the correct temperature or causing abnormal engine operating temperatures. The cooling system should also be checked for adequate coolant level and condition when replacing the thermostat.

Always confirm the engine model and serial number before ordering, as Perkins engines can use different thermostat specifications. The 054/2485613 reference corresponds to the 2485613 82°C, 54 mm thermostat specification.
