What temperature does the Subaru thermostat open?
As a Subaru owner or enthusiast, understanding how your vehicle's cooling system operates is essential for maintaining optimal engine performance. One critical component of this system is the thermostat, which regulates the flow of coolant to ensure the engine stays within its ideal operating temperature range. In this article, we’ll explore the specific temperature at which a Subaru thermostat typically opens and why this matters for your vehicle's health.
Understanding the Role of the Thermostat
The thermostat in your Subaru is a small but vital device located between the engine and the radiator. Its primary function is to control the flow of coolant based on the engine's temperature. When the engine is cold, the thermostat remains closed, allowing the engine to warm up quickly. Once the engine reaches a specific temperature, the thermostat opens, allowing coolant to flow to the radiator and prevent overheating.
At What Temperature Does the Subaru Thermostat Open?
Most Subaru thermostats are designed to open at approximately 170°F to 190°F (77°C to 88°C). This range ensures that the engine warms up efficiently while also preventing it from overheating during operation. The exact opening temperature can vary slightly depending on the model and year of your Subaru, as well as the specific thermostat installed.
Why Is the Thermostat Opening Temperature Important?
The thermostat's opening temperature is crucial for several reasons:
- Efficient Engine Warm-Up: A thermostat that opens too early can prevent the engine from reaching its optimal operating temperature, leading to reduced fuel efficiency and increased emissions.
- Overheating Prevention: A thermostat that opens too late can cause the engine to overheat, potentially leading to severe damage.
- Consistent Performance: Maintaining the correct temperature ensures that the engine operates smoothly and reliably under various driving conditions.
Signs of a Faulty Thermostat
If your Subaru's thermostat is not functioning correctly, you may notice the following symptoms:
- The engine takes too long to warm up or doesn’t reach the normal operating temperature.
- The temperature gauge fluctuates or shows the engine overheating.
- Coolant leaks around the thermostat housing.
- Poor heater performance in cold weather.
When to Replace Your Subaru Thermostat
Thermostats are durable but not immune to wear and tear. If you experience any of the symptoms mentioned above, it may be time to replace the thermostat. Regular maintenance and inspections can help identify potential issues before they lead to more significant problems.

Frequently Asked Questions
Is 210 a good coolant temp?
So, what's the normal temperature for your vehicle's engine? Most experts agree that your engine should run between 195 degrees and 220 degrees.
What degree is a thermostat open?
It does not permit water to enter the radiator i.e. thermostat disconnects the engine from the radiator until it reaches to the sufficient operating temperature, generally 80°C in automobile water cooling system. Then afterwards the thermostat adjusts flow of coolant to the radiator.
What is the temperature of the thermostat in a Subaru?
207°-216°.
At what temperature does a thermostat start to open?
between 180 and 195 degrees
Most car thermostats are rated to begin opening between 180 and 195 degrees and will reach the fully open position around 20 degrees higher, allowing coolant to flow between the radiator and engine.
What is the normal temperature for a car thermostat?
between 195 degrees and 220 degrees
Most experts agree that your engine should run between 195 degrees and 220 degrees.
What is the 20 degree rule on a thermostat?
Simply put, it means you should never set your thermostat for a temperature more than 20 degrees cooler than the outside air. Why not? Most air conditioning systems can only handle a 20-degree difference between the outside and inside air temperatures.
What is the normal coolant temperature for a Subaru?
around 195 to 220 Fahrenheit
Normal Coolant Temperature
If your engine's temperature gauge ever goes into the red zone, you should stop the car immediately before you cause any serious damage to the engine. Normal coolant temperature will be around 195 to 220 Fahrenheit (approx. 90°C) and anything outside of this range can start causing problems.
At what temperature does a car fan turn on?
between 200 and 230 degrees Fahrenheit
In most vehicles, the radiator fan is programmed to turn on when the engine coolant reaches a temperature between 200 and 230 degrees Fahrenheit (93 to 110 degrees Celsius). However, some vehicles may have different temperature thresholds for the radiator fan to activate.
What is the typical opening temperature of a thermostat?
As an example, a 180 degree thermostat should start to open at 177 - 183 degrees, and will not be fully open until the coolant around it is 195 - 200 degrees.
What temperature should a thermostat open and close at?
Once the engine heats up to its designed operating temperature, typically around 90-100 degrees Celsius, the thermostat opens. This opening allows the hot coolant to pass through the radiator, where it's cooled down before returning to the engine, maintaining a constant, optimal temperature.
