What temperature do Subaru fans come on?
Subaru fans, the cooling devices used in Subaru vehicles, typically operate at temperatures between 180-210°F (82-99°C) to maintain optimal engine performance and prevent overheating. This temperature range is essential for ensuring the proper functioning of Subaru's renowned all-wheel-drive systems and powerful engines.
Importance of Proper Fan Temperatures
The Subaru fan plays a crucial role in the vehicle's cooling system, helping to dissipate heat generated by the engine and other components. Maintaining the correct fan temperature is essential for several reasons:
- Engine Efficiency: Optimal fan temperatures help the engine run at its peak efficiency, reducing fuel consumption and emissions.
- Overheating Prevention: If the fan temperature is too low, the engine may overheat, leading to potential damage and reduced performance. Conversely, if the temperature is too high, the fan may not be able to effectively cool the engine.
- Durability: Proper fan temperatures help extend the lifespan of the engine, transmission, and other critical components by preventing excessive heat buildup.
By understanding the importance of Subaru fan temperatures, owners can ensure their vehicles operate at peak performance and reliability.
Factors Affecting Fan Temperatures
Several factors can influence the temperature of Subaru fans, including:
- Ambient Temperature: Hotter outdoor temperatures can cause the fan to work harder, leading to higher operating temperatures.
- Engine Load: Heavy loads, such as towing or climbing steep hills, can increase the heat generated by the engine, requiring the fan to work harder and run at higher temperatures.
- Fan Design and Efficiency: The specific design and efficiency of the Subaru fan can affect its operating temperature range.
- Coolant System Condition: Any issues with the coolant system, such as leaks or blockages, can impact the fan's ability to effectively dissipate heat.
By understanding these factors, Subaru owners can better monitor and maintain their vehicle's cooling system to ensure optimal fan performance.
Monitoring and Maintaining Subaru Fan Temperatures
Subaru owners can monitor their vehicle's fan temperatures using the on-board diagnostic system or a specialized scan tool. If the fan temperature falls outside the recommended range, it may indicate a problem that requires attention, such as a malfunctioning fan, coolant system issue, or other underlying problem.
Regular maintenance, such as changing the coolant and inspecting the cooling system components, can help ensure the Subaru fan operates within the optimal temperature range and maintain the overall health of the vehicle's cooling system.
What temperature do Subaru fans kick on?
According to my 07 FSM, with the AC off, the fans should come on at low vehicle speed at between 205 and 210 F, and at high speed if the coolant reaches 212 F or more. I'm finding that the fans come on at low speed or stopped only after the coolant temperature reaches 212 - 214 F.
Is it normal for a car fan to come on?
The fan turning on is normal and a consequence of the hot coolant, not a cause.
What is the normal temperature for a Subaru?
normal is between 192-196 F while driving.
When should the fan run on a car?
The radiator fan will come on when the coolant temperature gets up to around 212 to 217 degrees F, and when the AC is on it will cycle on and off (or stay on) depending on the pressure of the refrigerant in the high side of the AC system.
What is the operating temperature of a fan?
Standard axial fans are good to 200°F. By moving the bearing housing upstream of the impeller, opening the bearing housing to the impeller, and by adding a cooling wheel to the shaft to pull cool air over the shaft and bearings, the maximum operating temperature goes up to 300°F.
What temp does Subaru thermostat open?
OEM Opening starts at 90°C (194°F) and is fully open at 95°C.
How do I know if my Subaru is overheating?
The temperature gauge on your Subaru's dashboard is a key indicator of engine temperature. Pay attention to the temperature gauge and ensure it stays within the normal range. If the needle consistently rises into the red zone or shows a higher temperature than usual, it is a clear sign of engine overheating.
Are Subarus prone to overheating?
Subaru vehicles have gained immense popularity among car enthusiasts for their reliability, performance, and versatility. However, like any other automobile, Subarus can encounter certain issues, with overheating being a common concern.
At what temperature should my cooling fan come on?
Your radiator fan should kick in at about 200 degrees Fahrenheit. If you notice your vehicle is overheating or at the very least running hotter than it normally does, listen for the fan to see if you can hear it.
What is the temperature indicator on a Subaru?
When you switch on the vehicle, the temperature light will briefly light up and then go off if the system is working properly. However, when the cooling system is faulty, the warning light is likely to stay on and turn red as the engine heats up.
