What is a Thermostat?

You’re probably thinking it’s a thermostat for your car, right? Well, you’re exactly right. A thermostat is a part of your car’s cooling system, and it’s actually a valve. When this important part of your vehicle's HVAC isn't functioning properly, you must replace it. The thermostat helps keep your engine at the right temperature. When you first fire up your car, and the engine is cold, the valve stays closed, blocking the coolant from circulating to the radiator while, and trapping in the heat, so the engine can continue heating until it gets up to the right temperature. Once the car's temperature is up and running and toastier than a summer day, the valve opens up, allowing the coolant to flow to the heating radiator and cool things down.

Symptoms of a failing Thermostat

Overheating

Your engine is powerful, and surrounded by gas, oil, and water. Overheating isn’t good. Hopefully this isn’t new information to you. Overheating often comes as a result of a faulty old thermostat, so that could be the culprit. If this is the case, making sure to get a thermostat replacement so that the new thermostat you install can keep your vehicle heating up to the right temperature.

How urgent is a Thermostat replacement?

The thermostat helps keep your engine at the right temperature, preventing it from heating up too much. If you don’t replace a faulty old thermostat and install a new thermostat, your engine might overheat. If you don’t get a thermostat replacement, the engine might overheat and cause serious damage. Surely, you don’t need to be told how bad that is or how much it might cost beyond fixing your thermostat. Regardless, if your thermostat is acting up, make sure that you replace it and install a thermostat replacement to keep your engine and HVAC heating correctly.
