The Most Common Car Engine Problems on Everyman Driver

Car engines are intricate systems that can encounter various issues over time. Here are some of the most common problems drivers may face:

Engine Misfire: Often caused by worn or faulty spark plugs, misfiring leads to uneven engine performance and reduced fuel efficiency.Regularly replacing spark plugs as per the manufacturer's recommendations can prevent this issue.citeturn0search0
Dirty or Contaminated Engine Coolant: Over time, engine coolant can become dirty, leading to overheating and potential engine damage.Flushing and refilling the coolant periodically helps maintain optimal engine temperature. citeturn0search0
Oil Leaks: Common in older vehicles, oil leaks can result from loose bolts, cracked gaskets, or worn seals. Regular inspections and timely oil changes are essential to prevent engine damage due to oil starvation. citeturn0search1
