Thermostats can completely ruin your engine if you don’t replace them when they show warning signs of being worn out or damaged. The thermostat plays a large role in keeping your engine running smoothly, opening and closing at certain times to regulate the temperature of your engine. If it sticks open or closed, your engine can overheat or not get hot enough, both of which are bad for it. If you notice your car’s temperature fluctuating more than usual, get this part looked at, and get a replacement if needed.
