When should a truck turbocharger be replaced?

The turbocharger in your truck plays a key role in increasing engine power and efficiency. Like any mechanical part, it may wear out over time. In this article, we will discuss when a turbocharger should be replaced, what are the symptoms of its failure, and when regeneration is sufficient and when replacement with a new one is required.


What does a turbocharger in a truck do?

The turbocharger plays an extremely important role in a truck engine. Its main task is to increase the amount of air supplied to the cylinders, which enables the generation of greater efficiency of the drive unit. It works on the principle of using the energy of exhaust gases to drive an impeller, which compresses the air supplied to the engine. Thanks to this, the engine runs more efficiently and the car has better performance and lower fuel consumption.


How to recognize a turbocharger failure?

Turbocharger failures can manifest themselves in many ways. Recognizing them at an early stage can protect against more serious engine damage and costly repairs. Below are the most common symptoms that may indicate problems with the turbocharger.

– Decrease in engine power – one of the first signals may be a noticeable decrease in engine power. If your car is not accelerating as it should and performance is significantly poorer, this may indicate a problem with the turbocharger.

– Increased fuel consumption – a damaged turbocharger may lead to increased fuel consumption. If you notice that your vehicle is starting to burn more fuel than usual, it’s worth checking your turbocharger.

– Smoke from the exhaust – white, blue or black smoke coming from the exhaust pipe may be a signal of problems with the turbocharger. Blue smoke indicates oil burning, which may be the result of turbocharger leaks.

– Unusual sounds – whistling, whistles or noises coming from under the hood may be a symptom of problems with the bearings or turbocharger rotor.

– Indicators on the dashboard – modern trucks are equipped with advanced diagnostic systems that monitor the operation of the turbocharger. If the check engine light comes on, it may indicate problems with this component.

When is a turbocharger suitable for regeneration?

Turbocharger regeneration can be a cost-effective solution, especially in the case of minor damage. This process involves disassembly, thorough cleaning and replacement of worn-out elements with new ones. Regeneration is possible when the damage is not too serious and mainly concerns consumable parts such as bearings, seals or rotor.

Regeneration is worth considering in the case of:

– minor oil leaks – if the turbocharger shows minor oil leaks, it is often possible to fix the problem by replacing the seals;

– damaged bearings – damaged bearings can be replaced during regeneration, which will restore proper operation of the turbocharger;

– contamination – if the turbocharger is dirty, thorough cleaning can restore its efficiency.

Regeneration is usually cheaper than replacing a new turbocharger, and it can significantly extend the life of this component.

When is it necessary to replace the turbocharger with a new one?

In some cases, turbocharger regeneration is not possible or cost-effective. In such situations, it is necessary to replace the turbocharger with a new one. Replacement is necessary when the damage is too severe and may involve key components that are impossible or uneconomical to repair.

A new turbocharger is necessary in cases:

– serious damage to the rotor – if the rotor is seriously damaged or cracked, regeneration will not be possible;

significant oil leaks – large oil leaks that flood the turbocharger may indicate more serious internal damage;

– damage to the body – cracks or other damage to the turbocharger body are difficult to repair and often require replacement of the entire unit;

– problems with sensors – if the sensors monitoring the operation of the turbocharger are damaged and their repair is not possible, replacing them with new ones is the only solution.

The Arcoore company offers owners of vehicles and vehicle fleets turbochargers for many trucks such as: Scania, DAF, MAN, Iveco, Solaris, Volvo, all manufacturers – Garrett, Holset, Cummins, BorgWarner. Please see the range of turbochargers.

Remember that regular servicing and caring for your turbocharger can significantly extend its life and ensure trouble-free operation of your truck.
