When to Replace a Subaru Thermostat
The thermostat in a Subaru should be replaced under certain circumstances. Here are some factors to consider:
1. Age and Mileage: The age and mileage of your Subaru can be indicators of when to replace the thermostat. While there is no specific mileage or time interval for replacing the thermostat, it is generally recommended to inspect and potentially replace it as part of regular maintenance, especially if your vehicle is older or has high mileage.
2. Coolant System Maintenance: If you are planning to perform coolant system maintenance, such as a coolant system flush, it is a good opportunity to consider replacing the thermostat as well. Over time, the thermostat can become worn or malfunction, leading to issues with temperature regulation.
3. Signs of Thermostat Failure: If you notice any signs of thermostat failure, such as the engine taking longer than usual to reach optimal temperature or the engine running hotter than normal, it may be time to replace the thermostat.
