  • Are Infiniti Q45 engine noises bad? Strange engine sounds can be a sign something’s off in your Infiniti Q45. Tapping or knocking could mean you're low on oil. A high-pitched whistle could signal an intake leak or misaligned belt. 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 Infiniti Q45 engine? Certain driving habits can damage your engine and should be avoided. These habits include 'running on fumes,' revving your engine while the vehicle is in Park, or pushing 'the pedal to the metal' before the engine has warmed up. Protect your engine’s performance and efficiency by distancing yourself from these habits.
  • Can I use water in my Infiniti Q45 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.
