How Well Do You Know Your Car Parts? Take the Quiz!
If this little device stops working, you’ll be stuck in a chilly ride. What is it?
Correct Incorrect The thermostat’s job is to keep your engine at the perfect temperature for smooth operation. If it gets stuck open, coolant flows through even when it isn’t needed, causing your car to take longer to warm up. If it sticks closed, the coolant can’t circulate, and you might overheat—definitely not what you want!
