Engine Q&A 1998 Mitsubishi Diamante

  • Why does the check engine light in my Diamante turn on when I start my car? It’s usually normal for your check engine light to turn on upon ignition. This is just your Diamante testing its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.
  • Why is my Mitsubishi Diamante making engine noise? Strange engine sounds can be a sign something’s off in your Mitsubishi Diamante. Tapping or knocking could mean you're low on 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 my Mitsubishi Diamante engine? Certain driving habits can damage your engine and should be avoided. These habits include 'running on fumes,' revving the engine while still in Park, or slamming the gas pedal while the engine is still cold. Steer clear of these habits to help protect engine performance and efficiency.
  • Can I use water in my Mitsubishi Diamante radiator? Only in emergencies. A 50/50 mix of coolant and water (or a pre-mixed) coolant is recommended. However, if you must keep driving when you're out of coolant, it's better to drive with water in your coolant reservoir than nothing.
  • What can cause a Diamante engine to suddenly stop? Your Diamante car engine could stop suddenly due to low fuel, electrical issues, overheating, a faulty ignition system, mechanical troubles, or sensor problems.
