What does a factory Toyota & Scion thermostat do, and how does it work? The short answer: it helps prevent engine overheats. However, how a simple valve in a cooling system does this is a little more complex. Yes, the original thermostat in your Toyota or Scion opens and closes, most often using a spring or piston. And yes, this regulates coolant circulation through your engine and radiator. But, for making sure coolant stays at the right temperature range, whether it's warm or cold out, their precise timing is key. If your temperature gauge gives constant readings, centered or just on the cold side, your thermostat is working normally. Thermostats don't really go bad with age, either. So, when to replace a car thermostat isn't a question that usually comes up. However, like any auto part, they can fail. Signs that a thermostat isn't working include a Check Engine light, the valve not opening or closing properly, and a stuck valve, but these usually show as engine and HVAC problems. If the valve malfunctions, it can't move coolant correctly; coolant can then either get trapped in your engine, causing an overheat, or circulate too much, keeping it from reaching the right temperature. As a result, engine efficiency tanks, and your AC and heating system can stop heating properly. That's not to mention that overheats can damage the valve, valve housing, and the surrounding hoses and gaskets. Nearby auto parts can even warp and malfunction. If you need to replace your car thermostat, the best choice for the project is a genuine Toyota & Scion thermostat. Avoid the hassle of searching for the right fit -- order yours from our online auto parts counter today.
