If your Infiniti has been hotter than it looks lately, then you may need a replacement Infiniti thermostat. An Infiniti thermostat is the difference between knowing and not knowing when your engine is overheating. An important part of your Infiniti's engine cooling system, your Infiniti thermostat is a spring activated valve that functions as a unit to detect the temperature in your engine compartment. If it is too hot in and around your engine, your Infiniti thermostat will open to release antifreeze throughout your Infiniti's cooling system in an effort to cool it down. Conversely, if it is not hot enough, the Infiniti thermostat will close or remain closed, keeping antifreeze from circulating and performing its cooling function, thereby allowing the engine to reach its ideal running temperature. Sometimes a thermostat can get stuck open or shut and if this happens, then you will need a replacement Infiniti thermostat. An indication that your Infiniti thermostat is defective is if your Infiniti engine is requiring longer warm up times and once it's running, begins to overheat right away. If you notice any of these signs, you should replace your defective Infiniti thermostat immediately, since your cooling system is vital to the health and well-being of your engine.
