Why is my car heated, yet not to the point of
overheating?

• An overheated engine will not only fail the MOT
  test, but it will also cause the engine to fail
  completely. To save time and money, check your
  vehicle's MOT status online and schedule an
  appointment with a garage that performs MOT
  testing service and car repairs.
