Thermostat

Thermostats are an important part present under the hood of your Mazda that operate alongside other cooling system parts. Thermostats adjust the flow of coolant that gets through to the radiator. It does this by opening and closing as needed to send or prevent coolant from getting through. Coolant helps prevent overheating and contributes to the proper working of the engine. Thermostats can get damaged over time and get stuck in an open or closed position, which can cause major issues. Changing your thermostat when you notice issues will ensure your engine continues to operate properly. Recognizing the symptoms of a failing thermostat is important to catch problems early. The issues will vary depending on the core problem. For instance, you may notice various temperature reads which are inaccurate or unpredictable. Improper reads such as excessively high or low also indicate problems with the thermostat (unless there are other underlying issues such as with the radiator). In some cases, this may cause starting issues with your vehicle. Replace your thermostat with an OEM part if you need to change it out. Aftermarket components may cause issues including erroneous temperature reads during travel. For Mazda OEM thermostat replacement parts and related components, you can visit our online store.
