Signs Your Truck Engine May Be Failing

Truck Engine

If your truck’s hood or exhaust are blowing smoke or flames, you probably already know your engine is in trouble. But did you know those aren’t the only signs to look out for?

Engine smoke and exhaust flames are only a couple of indicators that your truck engine is malfunctioning. Many other signs, on the other hand, are less visible. Heavy truck engine repair is critical, and you don’t want to wait until it’s too late because you didn’t notice these warning signs.

To help you properly maintain your truck engine, here are some critical signs to look out for.

1. Check Engine Light

Most trucks and other vehicles today have computers equipped with a check engine light. If the computer detects even a minor issue with your engine, the light will come on. Even if the issue turns out to be something minor, it’s better to have your engine looked at when this light comes on.

2. Overheating

Many factors can cause your truck to overheat, such as a coolant leak or a dirty air filter. Allowing the engine to overheat can cause severe damage. If your engine is overheating, it is imperative to stop driving it and get it into a shop for repair.

3. Excess Oil Consumption

Worn-out piston rings can cause excess oil consumption, allowing oil to leak into the engine’s crankcase. This lack of lubrication can severely damage your engine. If your engine consumes more oil than usual, do not delay servicing your truck engine.

4. Knocking Noises

Knocking noises in your truck can result from defective fuel injectors or faulty rod bearings. This is a significant threat to truck engine safety, as it poses a fire risk. Hyundai recently recalled over 153,000 vehicles in Canada due to worn-out bearings.

Knocking noises are a potential threat to your engine’s health and your safety.

5. Compression Loss

If your truck performs at lower power than normal, this could signify compression loss. This is due to a cylinder leak, a regular occurrence that happens with engine wear and tear. This can lead to misfires and generally poor performance from your truck.

6. Engine Stalls

Is your engine stalling when in idle or at a high RPM? This could be an issue related to fuel delivery, which can be traced to causes such as a weak fuel pump.
