Tail Lights: Critical for rear visibility and signaling stops.
When to Perform Light Inspections
Before each trip or shift
During routine maintenance checks
After any electrical repairs or modifications

The Rise in Aftertreatment Repairs and How Acting Early Can Save You Money
In recent years, the number of aftertreatment repairs on diesel trucks and trailers has noticeably increased. As emission standards have become more stringent, vehicles rely heavily on complex aftertreatment systems to reduce harmful emissions. These systems include components such as diesel particulate filters (DPFs), selective catalytic reduction (SCR) systems, and diesel exhaust fluid (DEF) dosing units. While crucial for meeting environmental regulations, these components also require regular maintenance and timely repairs to ensure they function properly.
Why Aftertreatment Repairs Are Increasing
Tighter Emission Regulations: Modern diesel engines use advanced aftertreatment technology to meet EPA and state emission requirements. This added complexity means more parts that can wear out or fail.

How Delaying Repairs Raises Costs
Waiting until aftertreatment problems worsen can cause extensive damage to other engine parts, leading to higher repair bills. For example:
A clogged DPF that is not addressed promptly can cause excessive backpressure, resulting in decreased engine performance and potentially damaging the turbocharger or exhaust valves.
Neglecting DEF system faults may cause the SCR catalyst to fail, which is costly to replace.
Persistent aftertreatment codes can trigger vehicle downtime, resulting in loss of income or delivery delays.
Tips to Keep Aftertreatment Repair Costs Down
Address Issues Immediately: If your dashboard signals or diagnostic tools detect an aftertreatment fault, have it inspected and repaired right away.
Regular Preventive Maintenance: Follow your vehicle manufacturer’s recommended maintenance schedule, including DPF cleaning and DEF system checks.
Monitor Fluid Levels and Quality: Keep DEF fluid at proper levels and use the correct type to prevent system failures.
Use Proper Fuel: Avoid off-spec diesel fuels that can accelerate soot buildup in filters.
Professional Diagnostics: Have expert technicians run thorough diagnostics to accurately pinpoint issues before they escalate.
Conclusion
The complexity and importance of aftertreatment system maintenance cannot be overstated. With aftertreatment repairs on the rise, the best way to avoid costly repairs and extended downtime is to act at the earliest sign of trouble. At Kingman Diesel Repair, we specialize in diesel, truck, and trailer aftertreatment system service and repair. Contact us promptly if you notice any warning signs — addressing problems early saves money and keeps your vehicle running smoothly.

Understanding Diesel Regeneration Systems and Selective Catalyst Reduction Systems: Why Expert Repairs Matter
Modern diesel trucks rely on advanced emission control technologies to meet stringent environmental standards. Two critical systems in this effort are Diesel Particulate Filter (DPF) regeneration systems and Selective Catalyst Reduction (SCR) systems. Understanding how these systems work and why it’s crucial to bring your truck to a knowledgeable mechanic for repairs can save you time, money, and ensure your vehicle operates efficiently.
Diesel Regeneration Systems
Diesel engines produce soot and other particulate matter during combustion. To reduce harmful emissions, trucks are equipped with Diesel Particulate Filters that trap soot. Over time, these filters fill up and must be cleaned through a process called regeneration.
Regeneration involves raising the temperature inside the DPF to burn off accumulated soot, converting it to ash. This can happen passively during normal driving or actively through engine management when sensors detect the filter is nearing capacity. If the regeneration process fails or is interrupted, it can lead to clogged filters, reduced engine performance, and even costly damage.
Selective Catalyst Reduction Systems
SCR systems reduce nitrogen oxides (NOx), harmful pollutants that contribute to smog and acid rain. The system injects a urea-based fluid called Diesel Exhaust Fluid (DEF) into the exhaust stream. The DEF reacts with NOx gases inside a catalyst, converting them into harmless nitrogen and water vapor.
Proper functioning of the SCR system is essential not only for meeting emissions regulations but also for maintaining fuel efficiency and engine health.
The Importance of Skilled Mechanics
Repairing and maintaining these sophisticated systems requires specialized knowledge and tools. Here’s why bringing your truck to an experienced diesel mechanic is important:
Accurate Diagnosis: Modern trucks have complex onboard diagnostics. Expert mechanics can quickly identify whether issues stem from the DPF, SCR system, sensors, or related components.
Proper Repairs and Maintenance: Incorrect handling of regeneration processes or SCR system repairs can cause system failures or trigger engine derate modes, leading to downtime.
Compliance with Emissions Standards: Skilled technicians ensure your emissions systems work within legal limits, helping you avoid fines and ensuring environmental responsibility.
Optimal Vehicle Performance: Well-maintained emission control systems improve fuel efficiency, power output, and overall engine longevity.
Conclusion
Diesel regeneration and SCR systems are essential for modern trucks to operate cleanly and efficiently. Due to their complexity, these systems require expert attention when repairs or maintenance are needed. At Kingman Diesel, Truck and Trailer Repair, our experienced mechanics have the skills and equipment to keep your emission systems—and your vehicle—running at their best. Contact us today to ensure your truck stays compliant and dependable.

The Importance of Aftertreatment System Maintenance: Why Regular Shop Visits Matter
Diesel-powered trucks rely heavily on their aftertreatment systems to reduce harmful emissions and comply with environmental regulations. Components like the Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR), and Exhaust Gas Recirculation (EGR) system work together to minimize particulate matter and nitrogen oxides (NOx) released into the atmosphere. Proper maintenance of these systems is essential for your vehicle’s performance, fuel efficiency, and longevity.
Why Aftertreatment System Maintenance Is Crucial
Over time, soot, ash, and other contaminants build up in the aftertreatment components. If left unchecked, this can lead to:
Reduced fuel efficiency
Increased engine wear and damage
Higher emissions leading to regulatory non-compliance
Unexpected downtime and costly repairs
By maintaining these systems regularly, you ensure optimal operation, prevent expensive breakdowns, and extend the life of your diesel engine.
What Does Aftertreatment System Maintenance Include?
When you bring your truck to a professional repair shop, technicians perform a thorough inspection and service that may include:
Cleaning or replacing the Diesel Particulate Filter (DPF)
Checking the SCR system for proper urea injection and catalyst condition
Testing sensors and electronic components for faults
Cleaning and inspecting the EGR valve and cooler
Updating software to optimize aftertreatment performance
Why Choose Professional Service for Aftertreatment Maintenance?
Aftertreatment systems are complex and require specialized knowledge and equipment for proper diagnostics and servicing. Attempting DIY fixes or ignoring routine maintenance can cause serious issues.
Visiting a knowledgeable truck repair shop ensures:
Precise diagnostics using advanced tools
Correct cleaning, repairs, or replacement of parts
Compliance with emissions standards
Peace of mind knowing your vehicle is in expert hands

Preventative Maintenance on Diesel Trucks: The Key to Longevity and Performance
At Kingman Diesel Repair, we understand that owning and operating a diesel truck is more than just a job—it’s a commitment. Whether you're running a business, hauling equipment, or relying on your truck for daily work, keeping it in top shape is essential. That’s where preventative maintenance comes in.
Why Preventative Maintenance Matters
Diesel engines are robust, but they are not invincible. Regular maintenance helps catch issues before they become costly problems. Think of it like tuning an instrument before a performance; a well-maintained engine runs smoother, more efficiently, and lasts longer. Neglecting this maintenance can lead to breakdowns, expensive repairs, and downtime that impacts your bottom line.
What Does Preventative Maintenance Include?
Oil and Filter Changes: Clean oil keeps the engine lubricated and cool. Over time, oil breaks down and collects contaminants that can cause wear.
Fuel System Checks: Diesel fuel systems are sensitive. Dirty filters or clogged injectors reduce performance and fuel economy.
Air Filter Replacement: A clean air filter ensures your engine breathes properly and performs at its best.
Fluid Inspections: Coolant, transmission fluid, brake fluid, and power steering fluid levels and conditions must be regularly checked.
Belts and Hoses: These components can degrade and crack over time, potentially causing breakdowns.
Brake and Tire Maintenance: Safety first—well-maintained brakes and tires are crucial for control and stopping power.
Battery and Electrical System Tests: Diesel trucks rely on strong batteries and electrical systems for starting and operation.
Scheduling and Record-Keeping
Following the manufacturer’s recommended maintenance schedule is essential. Keep a detailed record of service dates, mileage, and any repairs. This not only helps in planning future maintenance but also adds value when you decide to sell or trade your truck.
