What is Diesel Exhaust Fluid (DEF)?
Diesel Exhaust Fluid (DEF) is used to reduce the emissions of nitrogen oxides (NOx) in diesel engines. Diesel Exhaust Fluid (DEF) has the ability to break down nitrogen oxides into nitrogen and water vapor. This is the reason why it is important to get your DEF system checked regularly. Any issues with your diesel exhaust fluid service can affect the functioning of your diesel vehicle.


The Importance of Regular DEF Service
Most people assume that DEF Service has only to do with refilling the fluid in your vehicle. However, the DEF system plays an important role in keeping your diesel engine in working condition. Any issues with the DEF system, such as DPF (Diesel Particulate Filter), can result in poor performance of your vehicle, which can result in huge expenses for repair.
- DEF tank inspection and refill to ensure optimal fluid levels
- Cleaning and testing DEF injectors for efficient fluid distribution
- DPF cleaning and repair services to ensure optimal performance
- Diagnostic checks to identify any potential issues with your DEF system
DPF Repair and Replacement Services
A critical part of the diesel engine exhaust system is the Diesel Particulate Filter (DPF). The DPF captures soot and particulate matter from the exhaust gases before they can enter the environment, ensuring cleaner emissions. After being on the road for days with heavy loads, most trucks start showing signs of DPF clogging. At 2020 Truck and Trailer Repair, we provide all types of DPF service, including DPF repairs and DPF replacement.
Common Signs You Need DPF Repair
- Reduced engine performance or power loss
- Excessive fuel consumption
- Warning lights on your dashboard (such as the DPF or check engine light)
- Unusual engine noises or exhaust smoke
