Thermostat How It Works Symptoms Problems Testing Learn how the thermostat controls the engine cooling system and keeps the engine from overheating. see the diagrams of the cooling system and the thermostat, and how to test and replace it. R or rc wire (power) connected to the r power terminal to power the thermostat. w wire (heat), connected to the heating control. g wire (fan) connected to the fan control to operate a blower in your hvac system. y1 wire (cooling) connected to the y terminal compressor refrigerant system.
Engine Thermostat Explained Savree Once the temperature of the coolant rises to between 180 and 195 f (82 91 c), the thermostat starts to open, allowing fluid to flow through the radiator. by the time the coolant reaches 200 to 218 f (93 103 c), the thermostat is open all the way. if you ever have the chance to test one, a thermostat is an amazing thing to watch because what. An auto cooling system diagram is a visual representation of the components and flow of coolant in a vehicle’s cooling system. it shows how the various parts of the system are connected and highlights the path that coolant takes to regulate the engine’s temperature. the diagram typically includes key components such as the radiator, water. The auto cooling system diagram provides a visual representation of the different components that work together to regulate the temperature of your car’s engine. by understanding how this system works, you can better understand how to maintain and troubleshoot any issues that may arise. at the heart of the auto cooling system is the radiator. Every liquid cooled car engine has a small device called the thermostat that sits between the engine and the radiator. it serves as a valve to control coolant flow, and is designed to open and close at specific temperatures. when the engine is cold, the thermostat remains closed, blocking the flow of coolant to the radiator, allowing the engine.
