1986 Cadillac DeVille Engine Q&A

  • Why does the check engine light in my DeVille turn on when I start my car? It's okay if your check engine light comes on when you first start your vehicle. It’s just your DeVille firing up its circuits. The light should go off shortly. Bring your vehicle in if it doesn't.
  • Are Cadillac DeVille engine noises bad? Unusual noises can signal a problem with your Cadillac DeVille engine. Knocking or tapping could be a symptom of low oil. Whistling could mean a belt is misaligned or there's an intake leak. Squealing can be traced back to a loose fan belt, and grinding might be coming from the brakes, not the engine.
  • What could damage a Cadillac engine? [ordered-list-1-item-3-1]Are you unknowingly damaging your Cadillac DeVille engine? Certain driving habits can hurt your engine. These habits include driving on an empty fuel tank, flooring the gas pedal while the car is in Park, or pushing 'the pedal to the metal' before the engine has warmed up. Help sustain your engine’s performance and efficiency by staying miles away from these bad driving practices.
  • Can I add water to my Cadillac DeVille radiator? An emergency is the only time you should consider putting water in your radiator. Outside of that, it’s recommended you use a pre-mixed coolant or a 50/50 blend of water and coolant. However, if you need to continue driving your DeVille when you’re out of coolant, having water in the coolant reservoir is better than nothing.
  • Why did my DeVille engine suddenly stop? If your DeVille car engine suddenly stops, it could be due to overheating, low fuel, a faulty ignition system, sensor problems, electrical system trouble, or mechanical issues.
