How long does a Subaru thermostat last?

Subaru Thermostat Lifespan
The lifespan of a Subaru thermostat can vary, but generally, thermostats generally last for years, even for the lifetime of a vehicle. However, if the thermostat goes bad, it can cause overheating and may need to be replaced.
It’s important to note that the quality of the thermostat and whether it’s an OEM or aftermarket part can impact its longevity. Aftermarket thermostats may wear out sooner and cause damage to the head gasket, while OEM thermostats are designed specifically for Subaru vehicles.
If you suspect that your thermostat is going bad or your vehicle is overheating, it’s recommended to have a professional inspect the entire cooling system, including the radiator, thermostat housing, and all gaskets and hoses.
In summary, while there’s no set mileage for the lifespan of a thermostat, it’s essential to monitor the cooling system and address any issues promptly to prevent potential damage to the vehicle.
