Do I need an appointment, or can I just drop in?

We work by appointment so we can plan the bay time your vehicle needs. Call (480) 264-8879 or use the form and tell us the year, make, model, and what it is doing. We will let you know the next available time.

What kinds of vehicles and work do you handle?

We handle routine maintenance, brakes, A/C, diagnostics, transmission and driveline work, engine repair, diesel trucks, classic cars, and performance projects. Call with the year, make, and model so we can confirm the job is a good fit for the shop.

Do you offer any kind of warranty on your work?

Warranty coverage depends on the repair and the parts used. We will explain the coverage that applies to your job before you approve it, including any manufacturer or JASPER warranty involved.

Will I know the cost before you start?

We inspect and diagnose the vehicle, explain what we found, and give you an estimate before repair work begins. If the job changes after disassembly or further testing, we contact you before moving ahead.

Diesel & Cummins Repair

Keep the work truck working in Arizona heat and towing loads.

Call (480) 264-8879 Directions

Diesel trucks earn their keep, and Arizona heat, dust, towing, and idle time all add load. We handle maintenance and repair on diesel pickups, including Ram Cummins trucks, and we test the fuel, cooling, electrical, and emissions systems before condemning expensive parts.

Testing before replacing

Modern common-rail diesels depend on clean fuel, healthy filtration, and correct electrical supply. Hard starting or low power is not proof that an injection pump or injectors have failed. We test filter restriction, air entry, supply-side problems, and electrical faults first so you are not paying for parts the truck did not need.

For maintenance, we follow the specification and interval for your truck's model year and duty cycle rather than a one-size-fits-all schedule.

What we handle

Scheduled maintenance, oil, and filtration for diesel pickups
Fuel system, water-separator, and drivability diagnosis
Cooling system service and airflow inspection for towing
Electrical and sensor diagnosis for warning messages
Repairs matched to how the truck is actually used

Common questions

Before you schedule

How often should I service a 6.7L Cummins in Arizona?

Use the interval in your truck's diesel supplement, and change the oil when the oil-change indicator asks. Towing, idle time, and dust can qualify as hard use, so bring engine hours and your service history when you call.

My truck has low power and a fuel-pressure code. Is the pump bad?

Not necessarily. Filter restriction, air entry, and supply problems can cause the same symptoms. We test the supply and filtration side before recommending pump or injector work.
