FAQ's

Can you perform a forced DPF regen on the side of the road?

Yes. Our mobile diesel mechanics carry advanced diagnostic software capable of initiating forced regens, resetting aftertreatment codes, and pulling semi-trucks out of derate mode on-site.

Do you fix blown semi-truck turbos or water pumps mobile?

Yes. While internal engine rebuilds require a shop environment, we frequently perform major "bolt-on" engine repairs roadside, including swapping heavy-duty water pumps, turbos, and fuel injectors.

What light-duty diesel engines do you work on?

We service all major light and medium-duty diesel engines, including Ford Powerstroke, Chevy/GMC Duramax, and Ram/Dodge Cummins platforms, often used in hotshot trucking and commercial fleets.

Why did my semi-truck suddenly go into derate mode?

Derate mode is an automatic engine protection feature typically triggered by emissions system faults (like a clogged DPF or low DEF), severe coolant loss, or critical sensor failures. A computer diagnostic is required to pinpoint the exact cause.
