Our Unlimited Diesel Performance Complete Vehicle Health Inspection gives you full transparency about your truck’s condition

Keeping your diesel truck running strong through Ohio’s harsh winters and humid summers requires more than occasional oil changes. At Unlimited Diesel Performance in Bremen, Ohio, we understand that diesel truck maintenance is critical for preventing costly breakdowns and extending your vehicle’s lifespan. Whether you’re hauling equipment through Columbus, towing your RV to Hocking Hills, or navigating winter roads in Lancaster, following a comprehensive maintenance checklist ensures your Powerstroke, Cummins, or Duramax stays dependable year-round.

Ohio’s extreme weather puts unique demands on diesel engines that many drivers underestimate. Subzero temperatures can gel fuel and drain battery power, while summer heat stresses cooling systems during heavy towing. Our Unlimited Diesel Performance Complete Vehicle Health Inspection provides full transparency about your truck’s condition through detailed photos, videos, and tech notes. This thorough approach helps you prioritize repairs by urgency and make informed decisions that keep your truck on the road when you need it most.

Why Diesel Truck Maintenance Matters in Ohio

Ohio’s climate challenges diesel engines in ways that drivers in milder regions never experience. From frigid mornings in Bremen that thicken fuel and oil to summer heat that strains cooling systems while towing through New Albany, your truck faces constant environmental pressure. Regular diesel truck services protect your investment and prevent minor issues from becoming expensive failures.

Ohio's Weather Creates Unique Maintenance Needs

  • Cold winter mornings can cause diesel fuel to gel, making it difficult or impossible to start your truck
  • Snow, salt, and road chemicals accelerate corrosion on brake components, suspension parts, and underbody systems
  • Summer heat, while hauling agricultural equipment or towing a heavy load, strains your cooling system and transmission
  • Traveling to destinations like Hocking Hills with heavy trailers puts additional stress on drivetrain components

Preventative Maintenance Saves Money

Addressing small problems early prevents catastrophic failures that leave you stranded. A worn fuel filter might seem minor, but it can lead to injection pump damage costing thousands of dollars. Regular inspections catch issues like failing lift pumps, leaking coolant, or worn suspension components before they sideline your truck during peak work season.

Essential Diesel Truck Maintenance Services

Full synthetic oil is essential for diesel engines, especially during Ohio winters. We use Hot Shot Secret oil and additives that provide superior protection in extreme temperatures. Regular oil changes prevent sludge buildup, reduce engine wear, and maintain proper lubrication for critical components like turbochargers and high-pressure fuel systems.

How often: Every 5,000-7,500 miles, depending on your driving conditions and manufacturer recommendations.

Fuel Filter Replacement

Diesel fuel filters work harder than gasoline filters, removing water, contaminants, and debris that can damage injection systems. A clogged fuel filter reduces power, decreases fuel economy, and can cause hard starting or rough idling.

How often: Every 10,000-15,000 miles, or more frequently if you notice performance issues.

Coolant System Maintenance

Ohio’s temperature swings demand a properly functioning cooling system. We perform coolant flushes and inspect hoses, radiators, and water pumps for leaks or wear. For 6.0L and 6.4L Powerstroke owners, EGR cooler failures are common, and we catch these problems early through thorough inspections.

How often: Coolant flush every 30,000-50,000 miles or per manufacturer guidelines.

DEF System Service

Modern diesel trucks use Diesel Exhaust Fluid to meet emissions standards. DEF system problems cause check engine lights and reduced power. We diagnose and repair SCR system issues, DPF problems, and DEF quality concerns that affect truck performance.

Battery Drain and Electrical System Weakness

A battery that’s three or four years old may no longer hold enough charge to crank a diesel engine in freezing temperatures.

Common electrical issues in winter:

  • Reduced battery capacity: Cold temperatures dramatically decrease available power
  • Corroded terminals: Buildup prevents efficient electrical flow
  • Loose connections: Temperature changes loosen battery cables
  • Weak alternators: Older alternators struggle to keep batteries charged

Critical Winter Preparation for Diesel Trucks

Winter is the most demanding season for diesel engines in Ohio. Preparing your truck before the first freeze prevents cold-weather failures that leave you stranded.

Fuel System Winterization

  • Use winterized diesel fuel and fuel additives that lower the gel point
  • Replace fuel filters before winter to ensure clean fuel flow when temperatures plummet
  • Diesel fuel gels when temperatures drop below 15°F, blocking fuel filters and preventing your engine from running

Battery and Electrical System Testing

Cold weather reduces battery capacity by up to 50 percent. Diesel engines require more cranking power than gasoline engines, making a strong battery essential. We test battery condition, check connections for corrosion, and inspect the charging system to ensure reliable starts throughout winter.

Glow Plug Inspection

Glow plugs heat combustion chambers for easier cold starts. Failed glow plugs cause hard starting, rough idling, and excessive white smoke. We test glow plug operation and replace faulty units before winter arrives.

Brake and Suspension Maintenance

Brake, steering, and suspension repairs are among the most critical services we provide at Unlimited Diesel Performance. These systems take heavy abuse from towing, hauling, and rough Ohio roads, making regular inspections essential for your safety.

Brake System Inspection

We inspect brake pads, rotors, calipers, and brake lines for wear, damage, or corrosion. Road salt accelerates brake component deterioration, making regular inspections essential. We replace rotors rather than turning them, ensuring optimal braking performance.

Steering and Suspension Components

  • Ball joints, tie rod ends, control arms, and shock absorbers wear out faster when towing heavy loads
  • Loose or worn suspension components cause poor handling, uneven tire wear, and potential safety hazards
  • We thoroughly inspect your front-end components and replace worn parts before they fail

Common Diesel Truck Problems We Prevent Through Maintenance

Regular maintenance prevents the most common diesel engine failures we see in our shop. Understanding these platform-specific issues helps you appreciate why following a maintenance checklist protects your investment.

Powerstroke-Specific Issues We See and Prevent

  • 6.7L CP4 Injection Pump Failures: These high-pressure pumps fail catastrophically, sending metal debris throughout the fuel system and contaminating injectors, lines, and the tank. We convert failed CP4 pumps to S&S Diesel DCR Pumps for long-term reliability.
  • 6.0L, 6.4L, and 6.7L Lifter Failures: Roller lifter problems damage camshafts, requiring expensive engine repairs. Symptoms include ticking noises and rough idle. Regular oil changes with quality synthetic oil significantly reduce this risk.
  • 6.0L EGR Cooler and Head Gasket Failures: Warning signs include losing heat at stoplights or mysterious coolant loss. Our cooling system inspections during maintenance catch early warning signs before these expensive failures occur.
  • 7.3L Fuel Injector Wear: The reliable 7.3L Powerstroke still experiences injector wear from fuel contamination. We rebuild 7.3L Powerstroke injectors in-house, restoring performance at a fraction of replacement cost. For all other Powerstroke models, we diagnose injector issues and replace them with quality Bosch or Alliant Power injectors.

Cummins-Specific Issues We Address

  • VP44 and Lift Pump Failures (1998-2002): When the factory lift pump fails, it starves the VP44 injection pump, causing both to fail. Regular fuel filter changes and lift pump inspections prevent these cascading failures.
  • Dropped Valve Seats (2003 and Up): Cylinder head cracks allow valve seats to drop into cylinders, causing catastrophic engine damage. Our machine shop capabilities allow us to repair these heads properly.
  • CP4 Injection Pump Failures (2019-2020): Newer Cummins engines use problematic CP4 high-pressure fuel pumps that fail catastrophically. We convert failed CP4 systems to the proven CP3 pump design for improved long-term reliability.
  • Injector Replacements: At Unlimited Diesel Performance, we replace Cummins injectors with genuine Bosch, DDP (Dynomite Diesel Performance), or S&S Diesel replacements, depending on the power level you’re trying to achieve and your vehicle’s usage.

Duramax-Specific Issues We Fix

  • LB7 Injector Failures (2001-2004): These injectors fail frequently, causing rough running, poor fuel economy, and hard starting. We replace them with quality Bosch or S&S Diesel injectors tailored to your goals and vehicle usage.
  • CP4 Injection Pump Problems (2011-2016): Duramax CP4 pumps suffer the same catastrophic failures as other platforms, sending metal debris throughout the fuel system. We perform CP3 pump conversions to eliminate this weak point and protect your investment.
  • Allison Transmission Limp Mode: Performance upgrades can trigger transmission protection modes. We diagnose these issues and recommend appropriate solutions for your power goals.
  • Fuel Injector Solutions for Modern Duramax Engines: At Unlimited Diesel Performance, we offer genuine Bosch or S&S Diesel fuel injectors for all modern Duramax engines, including the LB7, LLY, LBZ, and newer models, that are tailored to your goals and vehicle usage.
