What to Look for When Buying a Used Diesel Pickup
Buying a used diesel truck requires a keen eye and thorough inspection. Here’s a checklist:
- Pre-Purchase Inspection (PPI) by a Diesel Specialist: This is non-negotiable. A qualified mechanic specializing in diesel engines can identify potential issues that an untrained eye would miss, saving you thousands down the line.
- Maintenance Records: Demand a complete service history. Regular oil changes (with correct spec oil), fuel filter replacements, and transmission services are critical for diesel longevity. Look for evidence of consistent, quality maintenance.
- Engine and Drivetrain Inspection:
- Leaks: Check under the truck for oil, coolant, or fuel leaks.
- Smoke: Start the truck cold. White smoke (especially persistent) could indicate coolant issues or bad injectors. Blue smoke suggests oil burning. Black smoke (especially under acceleration) can be normal for older diesels but excessive amounts could mean injector issues or turbo problems.
- Unusual Noises: Listen for knocking, ticking, or excessive turbo whine.
- Transmission: Check fluid levels (if possible) and observe shifting behavior during the test drive. It should be smooth, without hesitation or harshness.
- Turbine Play: If possible, remove the intake hose and check for excessive shaft play in the turbocharger.
- Emissions Systems (DPF, EGR, DEF): If the truck is 2007.5 or newer, it will have these systems. Inquire about their maintenance and history. Issues with these components can be costly to repair.
- Rust and Body Condition: Check the frame, rocker panels, wheel wells, and brake lines for excessive rust, especially in colder climates where salt is used on roads.
- Mileage vs. Engine Hours: For diesels, engine hours can be as important as mileage, especially for trucks that spend a lot of time idling (e.g., work trucks). Some trucks display both.
- Test Drive: Drive the truck under various conditions – empty, with a load if possible, city, highway. Pay attention to acceleration, braking, steering, and any warning lights. Engage 4×4 if applicable.
- VIN Check/Vehicle History Report: Use services like CarFax or AutoCheck to review the truck’s accident history, title status (salvage, flood, etc.), and reported service records.
Common Challenges and Solutions
While durable, used diesel trucks can present specific challenges, particularly with modern emissions systems.
- Emissions System Issues (DPF, EGR, DEF):
- Challenge: Clogging of Diesel Particulate Filters (DPF), failure of Exhaust Gas Recirculation (EGR) coolers, or issues with the Diesel Exhaust Fluid (DEF) system. These can lead to reduced performance, warning lights, and expensive repairs.
- Solution: Adhere strictly to maintenance schedules, especially regarding DPF regeneration cycles. For EGR coolers, regular cleaning or replacement may be necessary. Ensure DEF fluid is always topped off and of good quality. Be wary of "deleting" these systems, as it’s illegal in many areas and can void warranties.
- Injector Problems:
- Challenge: Worn or clogged fuel injectors can lead to misfires, reduced power, and excessive smoke.
- Solution: Use quality diesel fuel, consider fuel additives specifically designed for diesels, and have injectors professionally serviced or replaced if issues arise.
- Cost of Parts and Labor:
- Challenge: Diesel-specific components and the specialized labor required to work on them can be more expensive than for gasoline engines.
- Solution: Factor this into your budget. Learn basic DIY maintenance (oil changes, fuel filter replacement) to save on labor costs.
- Cold Weather Starting:
- Challenge: Diesels can be harder to start in very cold temperatures due to the fuel’s properties and the need for higher compression.
- Solution: Ensure glow plugs are in good condition, use a block heater, and consider anti-gel fuel additives in winter.
Maintenance Tips for Longevity
Proper maintenance is the cornerstone of a long-lasting diesel truck.
- Frequent Oil and Filter Changes: Use the correct type and viscosity of synthetic diesel-specific oil. Adhere to manufacturer-recommended intervals, or even slightly shorter ones if you tow heavily.
