What is the function of the TCV valve?

What is a temperature control valve or temperature regulator? Temperature regulators and temperature control valves (sometimes referred to as TCV) are designed to control the temperature of a process by controlling thermal fluid pressure or flow in compressors, tank jackets, heating coils, or other heating elements.

What does the thermo control valve do on a Subaru?

The result premature failure and cracking posing a significant engine overheating. And safety hazard allegedly Subaru has known about this since at least 2021. And attempted an update.

How do I know if my heater control valve is bad?

Signs of a bad heater control valve

1. No heat coming out.
2. Heat always on and cannot be turned down.
3. Heat output changes with no changes in the heat setting.
4. Temperature gauge reads hot.
5. Low coolant level.
6. Coolant leak.

How do you know if your control valve is bad?

One of the most obvious indicators of a faulty control valve is leakage. Leakage can occur either internally or externally. Internal leakage is when the valve does not close completely, allowing some fluid or gas to pass through when it should be shut.
