I've been hearing a noise coming from my car's engine. What should I do?

Check the oil level and make sure it is at the proper level. 2 Make sure all of the belts and hoses are properly tightened.3 If you hear any grinding or clanking noises, have your mechanic check the engine for any signs of wear and tear.4 You may also need to replace some parts such as the timing belt, water pump, or spark plugs.5 If none of these steps work, then you may need to take the vehicle to a mechanic for further inspection.
