How long does Subaru thermostat last?
The average lifespan of a Subaru thermostat is typically between 60,000 to 100,000 miles, or around 5 to 10 years of normal driving. However, the actual lifespan can vary depending on factors such as driving conditions, maintenance history, and the quality of the thermostat itself.
Understanding the Subaru Thermostat
The thermostat in a Subaru vehicle is a critical component that regulates the engine's operating temperature. It is responsible for controlling the flow of coolant between the engine and the radiator, ensuring the engine reaches and maintains its optimal operating temperature. The thermostat is designed to open and close based on the engine's temperature, allowing the coolant to circulate and keep the engine from overheating.
Factors Affecting Thermostat Lifespan
Several factors can influence the lifespan of a Subaru thermostat:
- Driving Conditions: Vehicles driven in harsher environments, such as extreme heat or cold, or those that frequently tow heavy loads, may experience a shorter thermostat lifespan due to the increased stress on the engine and cooling system.
- Maintenance History: Regular coolant flushes and timely thermostat replacements can help extend the lifespan of the thermostat. Neglecting maintenance can lead to premature failure.
- Thermostat Quality: The quality of the replacement thermostat can also impact its lifespan. Using a high-quality, OEM-approved thermostat is recommended to ensure optimal performance and longevity.
It's important to note that the thermostat is a relatively inexpensive component, and it's generally recommended to replace it as part of a routine maintenance schedule or if any issues are detected, such as the engine taking longer to reach operating temperature or the coolant not circulating properly.
Symptoms of a Failing Thermostat
Some common signs that a Subaru thermostat may be failing include:
- Slow Engine Warm-Up: If the engine takes an unusually long time to reach its normal operating temperature, it could indicate a stuck-closed thermostat.
- Overheating: A stuck-open thermostat can cause the engine to overheat, as the coolant will not be able to circulate properly.
- Fluctuating Temperatures: If the engine temperature is constantly fluctuating, it may be a sign of a malfunctioning thermostat.
If any of these symptoms are observed, it's recommended to have the thermostat inspected and replaced if necessary to prevent further damage to the engine and cooling system.

How long do Subaru thermostats last?
A car thermostat is designed to last a long time – typically around 100,000 miles or 10 years. However, various factors can impact its lifespan. First, driving conditions play a role. If you regularly drive in hot weather or stop-and-go traffic, your thermostat may suffer additional stress.
Can I drive a car with a bad thermostat?
If you drive with a bad thermostat, your car could overheat, causing severe and expensive engine damage. And while it's technically possible to drive without a thermostat, we don't recommend it. Your car will not reach an acceptable operating temperature, resulting in higher fuel consumption and excessive engine wear.
How can I tell if my cars thermostat is bad?
5 Signs Your Thermostat Is Broken
- You Notice Erratic Temperature Changes.
- You Find Incorrect Readings on the Temperature Gauge.
- Your Vehicle Makes Concerning Noises.
- You Find Coolant Leaks.
- You Notice Problems with the Heating System.
Do subarus have two thermostats?
And you got this little itty bitty baby one what's that about well modern subarus. Again most of them not all of them. Have two thermostats. One is for your engine coolant. And one is for your cvt.
What are the symptoms of a bad thermostat in a car?
Accurate Auto lists these signs below.
- Odd Temperature Gauge Readings. Your temperature gauge should register cold when you first start your car and slowly build up to normal as the engine warms up.
- Air Temperature Changes.
- Coolant Leaks.
- Strange Sounds.
- Heater Problems.
What is the life expectancy of a thermostat?
about 10 years
The Lifespan of a Thermostat
On average, most thermostats last about 10 years, depending on the model, usage, and proper maintenance. However, many people decide to replace their unit sooner to take advantage of new energy-saving technologies.
When to change a Subaru thermostat?
When to consider replacing the engine cooling system thermostat:
- Engine overheats. A thermostat with the valve stuck closed is a common cause of engine overheating.
- Temperature gauge reads too low or too high.
- Cooling system repairs.
How do I know if my Subaru thermostat is bad?
Strange Sounds and Temperature Changes
You may hear rumbling, boiling, or knocking coming from the radiator. All these signs point to an issue with your car's cooling system. The thermostat also affects the temperature of air that flows in your vehicle through the vents.
How long does a Subaru water pump last?
A failing water pump can also leak causing further loss of coolant. Water pumps are designed to last at least 100,000 miles, however, if your water pump fails, you should replace it with a high-quality original-equipment level unit.
