Turbo

Renault Trucks Offer

The role of the turbocharger is to increase the pressure of the intake gases, allowing improved filling of the cylinders. Like the injection and the pistons, it is part of a complex system and is designed to achieve the best possible combustion, guaranteeing maximum mobility, consumption, and reduced emissions.

A Renault Trucks Genuine turbocharger is the only part that allows this to be done because it is developed for your specific vehicle. For example, the profile of the turbine, the parameters of the engine ECU and the materials used are specific to your engine and maximize its efficiency.

The use of a non-genuine turbo could cause power issues with acceleration, it would decrease with the altitude, increase consumption (beyond 1%) and a warning on the dashboard that you are no longer achieving the legal emission standards causing the vehicle to shut down.

In conclusion, it could cost you more by not choosing a Renault Trucks Genuine turbo.

The best in-class

This component operates in an extremely aggressive environment, within the limits of existing materials, lubricants and manufacturing processes. It is verified and validated by numerous calculations and test sessions defined by Renault Trucks engineering teams: isolated tests on the turbo, tests on the complete engine, as well as vehicle tests all over the world, lasting thousands of hours. Production is constantly monitored to guarantee the best reliability and durability, so that your truck can continue its missions.

Our Reman range also maintains the same focus on quality, systematically replacing sensitive and wear parts with original parts that comply with the latest drawings and specifications, and using the correct assembly process to maintain original performance. In line with Renault Trucks standards, we do not accept turbocharger repairs.

Compliance with emissions regulations

The Renault Trucks turbo is designed to offer minimum fuel consumption, combined with optimum brilliance to guarantee minimum exhaust emissions. Indeed, the turbo reference is included in the approval file for Euro 6 trucks. As legislation becomes ever more stringent, turbo design is essential for maximum air volume, reduced soot and lower emissions. This sometimes involves technical evolutions, such as the gradual introduction of variable geometry turbochargers.

A turbo from another manufacturer with different characteristics will result in the truck's non-compliance with emissions legislation.

Mobility

To carry out their operation, our transport partners need to be able to rely on a transport solution that is constant over time. Any unplanned scenario takes time and can disrupt the logistics flow. They also need a vehicle with minimal emissions and impact to the environment whilst delivering to the heart of city centers (urban areas).

You can count on your Renault Trucks Genuine turbocharger: it has been optimized for each vehicle model to have the best combination of performance, fuel consumption and emissions. A non-genuine turbo could cause your engine to malfunction.

Serenity

Today's engine environment is extremely high pressured, and sensitive parts sit near the turbocharger, which can reach several hundred degrees. Our technicians are highly trained to ensure precise fitting, securing the correct spacing between parts, guaranteeing their lifespan. The parts are fitted with seals equipped with keying and the material is resistant to the extreme temperatures recorded during validation tests carried out before leaving the vehicle. Our experts will also check the parts essential to the performance and the life of your turbo (air cooler, air filters and the quality of the engine oil).

Savings

The lifespan of your turbo is dependent on the use of your vehicle and by the maintenance you keep. To maximize lifespan, service your vehicle at an authorized Renault Trucks dealer, who are highly trained to detect issues due to more demanding operations and advise accordingly.

Preventive maintenance of the turbo

Unfortunately, there aren't many reliable warning signs to detect the end of a turbo's life, it is as difficult as its harsh working conditions... One thing is certain, the additional costs generated will far exceed the cost of only the part itself:

  • A breakage of the wheel will cause immediate irreparable damage. Before stopping, the airflow will have swept debris into the turbo cooler and into the cylinders.
  • A lack of lubrication (bearings damaged by a lubricant that is too fluid or charred) will lead to an oil leak spilling into your catalyst.

In any of these scenarios, you will be required to tow your vehicle and replace these components. An additional cost ranging from € 4,000 to € 20,000. You will avoid this cost if you change your turbo before it breaks. The Renault Trucks network of highly trained experts will provide you with the best support and recommend a change at the right time.

  • Long-haul - distribution: between 400,000 and 450,000 km / between 500,000 and 600,000 km (DTI only) 
  • Construction site - distribution - BOM (> 50km/h): between 6,000 and 8,000 hours
Tips for a maximum lifespan
  •  Use Renault Trucks oil filters and Renault Trucks oil, and strictly observe oil change intervals. Polluted oil or oil that has lost its viscosity can quickly destroy your turbo's bearings.

Turbo failure: ~€2000 

Oil leak and catalyst contamination: ~€8000

FAQ

A competitor offers me a cheaper turbo. What's the risk ?

The turbo of your truck has been developed according to its engine, and in function of the shape of the pistons and the injection parameters. It's designed specifically for your truck.

A 3rd party turbo will not have been designed for your vehicle and you will not have the same high standard in efficiency, mobility and consumption, which could cost you more money to fix later on. For example, a consumption increase of 1% over 120,000km will cost you approximately € 500.

How can I maximise the life of my turbo?

There are two simple things to do: follow the recommended maintenance provided by the manufacturer (oil quality, interval, oil, air, and diesel filters) and wait 60 seconds before switching off your engine after your journey (to continue lubrication).

I don't trust Reman parts.

We systematically replace critical and wearable parts on our Reman parts, so you have no reason to doubt the quality. They have the same warranty as a new part because we have confidence in our renovation process.

Can I replace the turbo myself?

We do not recommend it: there are many parts close to each other in the engine environment, and it is important to position your turbo correctly. Otherwise, you run the risk of increasing temperatures in some areas, with a high risk of damaging other parts. Our technicians are highly trained and will fit your turbo correctly, guaranteeing its full lifespan.
