  Protect Your Warranty

Most aftermarket manufacturers have a specific maintenance program that needs to be carried out by a certified technician. Oftentimes there are components (burners, injectors, glow plugs) that require specific cleaning as well as software programs that need updating. Non-certified technicians will VOID YOUR WARRANTY! Our technicians are factory trained to provide these services to ensure original manufacturer warranty.

  Record Keeping

CARB requires fleets to keep service records for each filter. Furthermore, aftermarket DPF manufacturers require records of cleaning and service to be submitted for warranty approval. Poor record keeping could result in warranty denial and/or CARB fines.

  EGR/Injector Cleaning Service

The Exhaust Gas Recirculation system is susceptible to carbon build up which can lead to failed EGR valves, EGR Coolers and poor fuel mileage. This can cause higher than normal opacity resulting in diesel particulate filters requiring shorter cleaning intervals. Our cleaning system will flush the entire EGR system as well as the injection system without the need to remove any parts. The process will increase fuel economy, reduce opacity and extend the life of EGR components.

  Annual Preventative Maintenance

Prolong the life of your filter and minimize unnecessary engine repairs with preventative DPF maintenance. Along with cleaning the DPF system annually it is also recommended to perform an engine analysis which includes an opacity test while the DPF is off, scanning for any active faults and addressing engine issues before reinstalling the filter.
