As the powerhouse of your vehicle, the engine performs numerous complex actions to keep your car running. Over time, this constant activity can place wear and tear on the equipment, leading to severe car troubles that may require extensive auto repair. Fortunately, with routine maintenance and a little insight, drivers can spot many of these issues early on and seek assistance before the problem grows worse. To help you stay safe on the road, below are five common engine problems to always stay on the lookout for.

5 Engine Issues Every Driver Should Watch For

1. Coolant Leak

When coolant leaks, the engine can overheat and cause considerable damage under the hood. You likely have a coolant leak if you notice a puddle of green liquid under your car after it’s parked or if your levels are running low. In other cases, you may notice a white smoke burning off the engine or smell a sweet, acrid odor.   

2. Faulty Spark Plug

3. Bad Oxygen Sensor

Located in the exhaust manifold, oxygen sensors measure the amount of oxygen leftover from combustion and use that information to tell the engine how much fuel it should be burning. Typically, a malfunctioning oxygen sensor will cause the check engine light to turn on. It may also contribute to rough idling, low fuel economy, and emissions test failure. Fortunately, this part can be easily replaced by a skilled auto repair professional.

4. Dirty Oil

If you don’t follow your vehicle’s recommended oil change schedule, the fluid may get too contaminated, and eventually, cause debris to accumulate on various essential parts under the hood. In addition to causing engine lubrication issues, dirty oil may lead to poor fuel economy, loud noises, and darker exhaust.

5. Damaged Catalytic Converter

Found on the underside of the vehicle, the catalytic converter performs the essential task of removing harmful emissions from the engine. If this part becomes clogged or damaged, you may encounter reduced acceleration, dark exhaust smoke, sulfuric odors, or extra heat from under the vehicle.
