Will Subaru cover thermo control valve replacement?

Subaru generally covers the replacement of the thermo control valve under their vehicle warranty, provided the issue is not caused by neglect or improper maintenance. The specific coverage and terms may vary depending on the model year and location, so it's best to check with your local Subaru dealer or refer to your vehicle's warranty documentation.


Understanding the Thermo Control Valve


The thermo control valve, also known as the thermostat, is a critical component in a vehicle's cooling system. It regulates the flow of coolant to the engine, helping to maintain the optimal operating temperature. When the thermo control valve fails, it can lead to issues such as the engine running too hot or too cold, which can cause further damage if not addressed promptly.


Subaru's Warranty Coverage



  • New Vehicle Limited Warranty: Subaru's new vehicle limited warranty typically covers the thermo control valve for 3 years or 36,000 miles (whichever comes first). This warranty covers the cost of parts and labor for the replacement of the faulty component.

  • Powertrain Warranty: Subaru's powertrain warranty, which covers the engine, transmission, and other major drivetrain components, may also include coverage for the thermo control valve. This warranty typically lasts for 5 years or 60,000 miles.

  • Extended Warranty: Some Subaru models may be eligible for extended warranty coverage, which can provide additional protection for the thermo control valve beyond the standard warranty periods.


It's important to note that the warranty coverage may be subject to certain exclusions or limitations, such as damage caused by neglect, improper maintenance, or accidents. Owners should review their vehicle's warranty documentation or consult with their local Subaru dealer for the most up-to-date information on coverage.


Seeking Warranty Assistance


If a Subaru owner experiences an issue with the thermo control valve and believes it is covered under the warranty, they should take the vehicle to an authorized Subaru dealer for inspection and repair. The dealer will assess the problem, determine if the warranty applies, and handle the necessary repairs or replacement. Owners should be prepared to provide their vehicle's information, such as the model year, mileage, and any relevant service history.
