Recognizing early warning signs of engine trouble can help you address problems before they become severe. By paying attention to how your vehicle behaves, you can help prevent breakdowns and extend the life of your engine. At American Five Star Auto Repair & Transmission, we provide expert engine repair in the greater Tempe, AZ area. Here are five common signs of an engine issue. Strange Noises Coming from the Engine Unusual sounds such as knocking, tapping, or grinding can indicate serious engine problems. A knocking noise could be a sign of worn-out bearings. Tapping noises may signal low oil levels. Grinding sounds might indicate a problem with the water pump or alternator. Any persistent or loud noise should be inspected by the mechanic to help prevent more serious damage. Loss of Power/Poor Performance If your vehicle loses power while driving or feels sluggish, you’ve got a sign of an issue with the engine. Reduced performance can be caused by problems such as clogged fuel injectors, a failing mass airflow sensor, or worn-out spark plugs. If your car is not responding as it normally would, it’s best to have it checked to avoid further complications. Discolored/Excessive Smoke from the Exhaust The color of the smoke coming from your exhaust can tell you a lot about potential engine problems. Blue smoke indicates that oil is burning. White smoke suggests coolant is leaking into the combustion chamber, which may be due to a blown head gasket. Black smoke signals that the engine is burning too much fuel. If you notice discolored/excessive smoke coming from your exhaust, it’s essential to diagnose and fix the problem quickly. High Engine Temperature If your temperature gauge rises above normal levels, it’s an indication that your engine is overheating. Overheating can be caused by failing cooling system components, such as a malfunctioning thermostat, a leaking radiator, or a broken water pump. Driving with an overheated engine can lead to severe damage. Check Engine Light The check engine light is a clear indication that something is wrong with your engine. While it could be triggered by a minor issue like a loose gas cap, it can also signal more serious problems, such as a failing oxygen sensor, catalytic converter trouble, or ignition system failure. Ignoring the check engine light can lead to bigger and more expensive repairs, so it’s best to visit the shop for diagnostics ASAP.
