Fast Diagnostics

Our goal is to get you the information about your possible repairs quickly. We understand our customers don’t like to be left waiting on the details of their repair. Many of our happy clients brought their vehicles to us after waiting a week or more just for a diagnosis at the last shop. That’s why we offer same-day diagnostic guarantee when the vehicle is at our shop no later than 8:30am Monday-Friday. 441 Diesel offers dealer-level diagnostics at a fraction of the price. To schedule an appointment call us at 706-677-0060


441 Diesel is one of the select few shops in Northeast Ga. that has access to the IDSS Isuzu diagnostic software. This allows us the capability to correctly diagnose any heavy-duty Isuzu truck the first time. Isuzu makes great quality trucks but many shops around have not invested in dealer-level diagnostic software to be able to fix these truck quickly and correctly. We have ECM programming capability as well as access to the entire Isuzu parts catalog for OEM replacement parts (Genuine Izuzu) at wholesale pricing. Many fleets take their trucks to Atlanta just to be able to have their engine codes read. Now, they don’t have to!

441 Diesel offers 30-35% cheaper labor rates than shops in the Greater Atlanta area and we provide very quick turnaround time.

If you have an Isuzu truck and need any repairs call AJ at 706-677-0060.

Fleet Services

441 Diesel offers a variety of fleet services such as: DOT inspections, preventative maintenance, light system repair, and electrical repair. We service several fleets of emergency vehicles and we offer access to many aftermarket parts suppliers that other shops just don’t have access to. We also service propane trucks and we have access to specific lighting systems and safety equipment that is required for these vehicles. If you have a fleet and have any questions please do not hesitate to call us and ask about our fleet service contracts.


Heating and Air Repair

When you don’t have warm heat in the winter or cold air in the summer in your vehicle you are most likely suffering. Not to mention your defrost does not work correctly without a proper working A/C compressor. With that in mind, 441 Diesel has a state-of-the-art A/C machine and many specialized diagnostic tools to repair A/C leaks and performance issues correctly and quickly. We perform complete HVAC system replacements as well as A/C services/tuneups and have access to all service manuals for vehicles from 1990-2016. A proper charge on your vehicles A/C system could mean the difference between a system that lasts 20 years vs. a system that lasts 2 years. Call us to schedule an appointment.


General Preventative Maintenance

Does your vehicle need an oil change? A fuel filter replacement? Or are you just needing it checked over before a cross-country trip. 441 Diesel knows how to maintain your vehicle. Each vehicle brought in for preventative maintenance has the brakes checked, the transmission fluid checked, the differential fluid checked, and all belts/hoses inspected for any developing issues. Many quick-lube establishments are quick to sell you a cabin air filter but is that what you’re there for or are you there to know of any safety concerns or developing issues that can’t easily be seen. 441 Diesel greases any grease fittings on your vehicle as well as any optional equipment such as lift gates and cranes. We know from experience that seeing and catching a problem before it causes a breakdown is what preventative maintenance is for. We offer scheduled maintenance by manufacturer’s specifications as well as drop-in services. Call us today with any questions.


Diesel Engine Repair

441 Diesel specializes in diesel engine repair. Our experience and training with today’s modern diesels give us a unique insight into common failures as well as upgrades to prevent these failures. We offer ARP head stud upgrades in all light-duty diesel applications to prevent repeat head gasket issues as well as top-of-the-line machine shop work that ensures when we get your engine parts back from the machine shop they are equal to or exceed manufacturer’s specifications. We offer complete engine rebuilds, engine replacements, fuel system repairs, exhaust upgrades, and extensive turbocharger service. With the introduction of emission systems such as EGR and SCR you need a shop that understands how these systems work and what affect they have on your engine. These systems can not be diagnosed by replacing random parts. That’s why 441 Diesel invests heavily in OEM diagnostic software for all engines we service.
