Will a stuck thermostat cause no heat?

Thermostat. A faulty thermostat could be behind your car’s heater not working. If it isn’t opening up to let the coolant flow through it, the core can’t produce heat. Thermostats can also get stuck open causing the engine’s temperature to stay low.

How do you know if your thermostat is stuck closed?

If it does not start to flow, but the temperature gauge on your dashboard rises, your thermostat is stuck closed. If your coolant flows normally, there may be another cause of your overheating engine. To check the temperature of your coolant, start with a cool radiator and engine.

What causes a thermostat to fail?

Once the coolant engine reaches proper operating temperature, typically 180 to 200 degrees, the thermostat opens up and allows the coolant to flow through the engine. Sometimes the thermostat fails and must be replaced; there are four main reasons for failure: overheating, sludge, defect and age.
