When your engine begins to show signs of trouble, acting quickly can help prevent major damage and costlier repairs. At Integrity Auto Care, we provide expert engine diagnostics and repair in the greater South Beloit, IL area. Here are five common symptoms of engine trouble that shouldn’t be ignored.

Knocking or Tapping Sounds

If you hear a knocking or tapping sound coming from the engine, it could indicate a serious internal issue. These sounds are often caused by worn engine bearings or insufficient lubrication. If your engine starts making unfamiliar noises, it’s time to stop driving and have it inspected.

Discolored/Excessive Exhaust Smoke

Excessive or discolored exhaust smoke often points to significant engine trouble. Blue smoke typically means the engine is burning oil. White smoke may indicate a coolant leak into the combustion chamber, possibly due to a blown head gasket. Black smoke suggests the engine is burning too much fuel. These issues should all be checked right away.

Check Engine Light 

The check engine light is your vehicle’s way of telling you something is wrong. While some causes are relatively minor, others can be serious. If the light comes on, it’s best to have the vehicle scanned for codes. Ignoring the check engine light can result in reduced fuel-efficiency, poor performance, or further engine damage depending on the underlying issue.

Overheating

An overheating engine is a clear sign that something is wrong with the cooling system or internal engine components. If your temperature gauge climbs into the red zone or you see steam coming from under the hood, pull over safely. Continuing to drive while overheating can warp the cylinder head or blow the head gasket. A professional should diagnose the cause, whether it’s a faulty thermostat, coolant leak, or water pump failure.

Loss of Power or Stalling

If your engine is suddenly sluggish, struggles to accelerate, or stalls unexpectedly, there may be a serious problem with fuel delivery, ignition, or internal engine components. This can be dangerous if it happens while driving. Immediate inspection is necessary to identify and fix the issue before it worsens or leaves you stranded.
