Introduction

The Cummins 3056549 Thermostat Housing is a component designed for use in the engine cooling systems of commercial trucks. Its purpose is to house the thermostat, which regulates the flow of coolant through the engine. This housing plays a role in maintaining optimal engine temperature, ensuring efficient operation and longevity of the engine ¹.

Basic Concepts of Thermostat Housing

A thermostat housing is a part of the engine cooling system that encases the thermostat. The thermostat, in turn, controls the flow of coolant based on the engine’s temperature. When the engine is cold, the thermostat remains closed, preventing coolant flow and allowing the engine to warm up quickly. As the engine temperature rises, the thermostat opens, allowing coolant to circulate through the engine and radiator, thereby regulating temperature. The housing protects the thermostat and provides a secure connection point for coolant hoses and the temperature sensor ².

Purpose of the Cummins 3056549 Thermostat Housing

The Cummins 3056549 Thermostat Housing is specifically engineered to fit Cummins engines, playing a role in regulating coolant flow and maintaining engine temperature. By ensuring that the thermostat is securely housed and functions correctly, this component contributes to the overall efficiency and reliability of the engine cooling system. It helps in achieving the right balance of coolant flow to prevent overheating while allowing the engine to reach its optimal operating temperature ³.

Key Features

The Cummins 3056549 Thermostat Housing is characterized by its robust design and the use of high-quality materials. It is crafted to withstand the high pressures and temperatures of the engine cooling system.
