Diesel Truck Repair — Complete Brake Service (preview)

When you need a diesel truck repair shop in Columbus that's actually built for the work, Complete Brake Service has been doing it since 1986. Our shop has the lot space, the bays, and the equipment for diesel pickups, medium-duty diesels, and heavy diesel rigs. Whether you're an owner-operator hauling for income, a fleet manager keeping vehicles up time-wise, or a diesel pickup owner who's tired of dealership pricing, we work on your truck — and we work on it carefully, because diesel parts are expensive and bad guesses cost real money.

Diesel Truck Services

From routine maintenance through major engine and emissions work — Powerstroke, Cummins, Duramax, and commercial diesel platforms.

Engine Diagnosis & Repair

Hard starts, no-starts, loss of power, knocking, and the kind of intermittent issues that have stumped other shops. We diagnose carefully before recommending repair.

Fuel System & Injection

Fuel injectors, high-pressure fuel pumps, fuel filters, fuel rail issues, and the diesel-specific delivery problems that gas-only shops aren't equipped to handle.

Emissions: DPF, DEF & EGR

DPF cleaning and replacement, DEF system service, EGR repair, regen issues, and the emissions-related faults that drive most modern diesel check engine lights.

Maintenance & Heavy-Duty

Diesel oil changes, coolant service, glow plugs, turbocharger service, drive belts, and the routine maintenance schedules that keep diesels running for the long haul.

When to Bring Your Diesel In

Diesel issues rarely fix themselves. Catching problems early — especially with fuel and emissions systems — saves serious money down the road.

Hard starts or no-startsGlow plugs, fuel system, batteries, or starter — multiple possible causes that need diagnosis, not parts swapping.
Loss of powerReduced power under load points to fuel delivery, turbocharger, EGR, or DPF restriction issues. The earlier diagnosed, the cheaper to fix.
Excessive smokeBlack smoke (rich/fuel), white smoke (coolant or unburned fuel), blue smoke (oil) — each tells a different story we can read.
Frequent regens or DPF lightIf your truck is regenerating constantly or showing a DPF warning, the system needs attention before it forces a derate.
Coolant or oil leaksDiesels develop external leaks at gaskets, seals, and lines. Spot the source early, fix before it gets in the way of operation.
Check engine lightModern diesel computers store fault codes that point straight at the issue. Bring it in, we'll scan and tell you what it's actually saying.

Why Columbus Diesel Owners and Fleets Choose CBS

Built for Diesel Work

Our shop has the lot space and bays for diesel pickups, medium-duty trucks, and full-size rigs. Most general repair shops can't physically take diesel work — we're built for it.

Decades of Diesel Experience

We've worked through every common diesel fault, every emissions update, every generation of injection system. Pattern recognition is the most valuable diagnostic tool there is, and we've earned ours since 1986.

Diagnose Before You Spend

Diesel parts are expensive. A bad guess on an injector or DPF can cost thousands. We test, scan, and isolate the actual cause before recommending any major work — and we'll show you the data behind the diagnosis.

Honest Pricing, No Surprises

Clear written estimates before any work. No surprise fees, no work without your approval. We're after long-term customers, not single transactions.

Diesel Truck Repair Questions, Answered

The questions Columbus diesel owners and fleet operators ask us most.

What kinds of diesel trucks do you service?

We service the full range — diesel pickups (F-250/F-350, Ram 2500/3500, Silverado/Sierra 2500/3500 HD), medium-duty diesels, dump trucks, semi-trucks, and commercial diesel rigs. Engine families include Powerstroke, Cummins, Duramax, and the commercial diesel platforms common in fleet vehicles. Our shop is sized for any of them.

Do you handle DPF, DEF, and EGR issues?

Yes. Modern diesel emissions systems — diesel particulate filter (DPF), diesel exhaust fluid (DEF) injection, and exhaust gas recirculation (EGR) — are the source of most check engine lights and power-loss complaints we see. We diagnose, clean, repair, and replace these systems. We don't perform emissions deletes, but legitimate repair to factory spec is squarely in our wheelhouse.

How often should diesel oil be changed?

Diesel oil change intervals vary widely based on engine, oil type, and operating conditions. Light-duty diesel pickups typically run 7,500 to 10,000 miles between changes; commercial diesels often go longer with bypass filtration. Severe service (heavy towing, idling, dusty conditions) shortens the interval. Follow your owner's manual or fleet maintenance schedule, and don't skip it — diesel oil works harder than gas-engine oil.

Why is my diesel hard to start in cold weather?

Cold-start issues on diesels usually trace to glow plugs, batteries, fuel gelling, or fuel system air. Diesel doesn't ignite from spark — it relies on compression heat, and cold engines need help. We test the glow plug system, charging system, and fuel delivery to isolate which is causing your cold starts. Most cold-start fixes are inexpensive once the actual cause is identified.

What's a regen and why is my truck doing it so often?

A "regen" is a regeneration cycle that burns soot out of the diesel particulate filter (DPF) at high temperature. Modern diesels regen automatically during normal driving; you usually don't notice. Frequent regens — or a forced manual regen request — usually mean the DPF is clogged, a sensor is reading off, or you're doing too much short-trip driving for the system to complete cycles. Worth diagnosing before it forces the truck into a power-reduced derate.

Can you replace diesel fuel injectors?

Yes. Injector replacement is one of the bigger diesel repair jobs, and one of the places where diagnosis matters most — replacing all eight injectors when only one is failing is an expensive mistake. We test injector performance and target only what actually needs replacement. We can also handle high-pressure fuel pump and fuel rail work when those are the cause.

Do you handle commercial fleet diesels?

Yes. We work with fleet operators on diesel pickups, vans, and medium- and heavy-duty trucks — preventive maintenance schedules, DOT-compliant inspections, repair work, and the day-to-day fixes that keep vehicles moving. Schedule ahead and we'll make sure your truck spends as little time off the road as possible.
