How to Inspect a Used Diesel Pickup Truck
To properly perform a pre-purchase evaluation, buyers must execute a cold start to detect injector issues, remove the oil cap to check for crankcase pressure blow-by, analyze exhaust emissions, and inspect the Diesel Exhaust Fluid system. Furthermore, examining steering linkage play and checking the hitch for frame stress reveals prior heavy towing abuse.
Top 3 Checks to Ensure a Healthy Used Diesel Pickup Truck
- Engine Health Check: Unscrew the oil cap while idling; excess smoke indicates worn piston rings.
- Emission System Inspection: Look for Diesel Exhaust Fluid crystallization around injectors and verify DEF tank heater functionality.
- Steering & Frame Evaluation: Inspect track bar bushings, ball joints, and receiver hitch stress cracks.
What to Look for When Buying a Used Diesel Truck with High Mileage
When buyers evaluate heavy-duty rigs, understanding what to look for when buying a used diesel truck with high mileage prevents costly mistakes. At Texas Truck Barn in Fort Worth, Texas, our team sees high-mileage trucks every day. Consequently, we know where wear hides.
The Time When You Don’t Want to Strike Oil
First, inspect the oil filler cap while the engine runs. Excess smoke or pressure indicates blow-by from worn piston rings. Furthermore, check the exhaust color. Blue smoke signals burning oil, while white smoke indicates coolant leaks or failing fuel injectors.
Check Emissions
Additionally, examine the emissions equipment. Modern diesels require a healthy Diesel Exhaust Fluid (DEF) system to operate correctly. Look for white, crusty DEF crystallization around lines, pumps, and injectors, which points to system leaks. Moreover, scan the vehicle for active OBD-II trouble codes regarding the Selective Catalytic Reduction (SCR) system.
Ensuring a Classy Chassis
Next, focus on the chassis. High-mileage trucks often endure heavy towing, which wears down steering geometry fast. Test the steering wheel for play, and inspect the track bar, drag link, and ball joints for cracked boots. Afterward, look closely at the rear receiver hitch and frame rails. Bent hitch pin holes or stress fractures around the crossmembers prove the truck pulled extreme loads regularly.
