7 Signs Your Car Needs Immediate Engine Check

Your car’s engine is the heart of your vehicle — and like any heart, it gives warning signs before failing completely. Ignoring those signs can lead to expensive repairs or even total engine failure. Here are 7 signs that tell you it’s time to bring your car to Car Doctor Limited for a professional engine check.

1# Unusual Engine Noise

If you hear knocking, tapping, or grinding noises under the hood, don’t ignore it. These sounds often mean worn-out bearings, loose parts, or serious internal damage. Early detection can save you up to 60% of potential repair costs.

2# Excessive Smoke from Exhaust

Different colors of smoke can indicate different problems:

• Blue smoke: Oil is leaking into the engine.
• White smoke: Coolant is entering the combustion chamber.
• Black smoke: Fuel system issue or dirty air filter.

Any of these means you need an expert diagnosis — immediately.

3# Check Engine Light On

This little light isn’t just for show!

When it comes on, your car’s onboard computer has detected a problem. Sometimes it’s minor (like a loose gas cap), but it could also mean a serious engine malfunction.

4# Decreased Fuel Efficiency

If your car suddenly starts consuming more fuel, it’s often because the engine isn’t burning fuel efficiently.
This could be due to:

• Faulty oxygen sensors
• Clogged fuel injectors
• Spark plug issues

A proper engine tune-up at Car Doctor can help restore performance and mileage.

5# Engine Overheating

When your temperature gauge goes up frequently, it’s a red flag. Possible causes include low coolant, radiator failure, or water pump issues. Overheating just once or twice can cause your engine head gasket to fail — a repair that can cost thousands!

6# Oil Leaks or Low Oil Level

If you notice oil stains under your car or the oil warning light turns on, take it seriously. Running an engine with low oil can cause permanent internal damage within minutes.

7# Poor Acceleration or Rough Idling

If your car feels sluggish or vibrates when idling, your engine may be misfiring or the fuel-air mixture may be off.
A quick diagnostic scan at Car Doctor’s computerized lab can pinpoint the issue instantly.
