Considering a used diesel truck for work or play? The Ford F-250 Powerstroke, especially models featuring the robust 7.3L engine, often tops the lists for reliability and capability. Last summer, I took the plunge and purchased a 2000 F-350 CCSB Lariat for under $9,000. It had 248,000 miles on the clock, which might seem high, but with a pre-purchase inspection from a trusted mechanic friend, I felt confident in my decision. Bringing her home was a great moment:
Owning a truck of this age and mileage definitely comes with the understanding that maintenance and potential repairs are part of the deal. Fortunately, online communities are invaluable resources, and I’ve found a wealth of information for my Powerstroke F250, often more than I even needed.
Many diesel enthusiasts believe the 7.3L Powerstroke is capable of reaching 500,000 miles or even more with proper care. While common issues like injector problems or sensor malfunctions can occur, the 7.3L is widely regarded as an exceptionally durable engine. If you’re considering an automatic transmission, be aware that these can sometimes present issues over time. Regular maintenance is absolutely key to keeping a Powerstroke F250 running strong. I personally stick to 3,000-mile oil change intervals. I might even send an oil sample to Blackstone Labs for analysis at some point, but consistent, timely oil changes are a straightforward way to ensure engine longevity.
Key Inspection Points for a Used Powerstroke F250
Before buying a used Powerstroke F250, especially one with higher mileage, a thorough inspection is crucial. Here are some key areas to examine:
Engine Compression Check
A simple check can give you a preliminary indication of engine health. With the engine running, remove the oil fill cap, turn it upside down, and place it loosely on the oil fill tube. If the cap is blown off forcefully, this could indicate excessive blow-by and potential compression issues. If it rattles or dances around, that’s generally a better sign.
Coolant System Health
The coolant’s condition is vital, particularly in older diesel engines. Older green coolant formulations often require Supplemental Coolant Additives (SCAs) to prevent cavitation and cylinder liner pitting. While newer gold coolants may be SCA-free, it’s essential to verify what type is in the truck. If it’s green coolant, you can use test strips from NAPA or Amazon to check the SCA concentration and ensure it’s within the recommended range. Neglecting SCA levels in green coolant can lead to serious engine damage.
Air Intake and Turbo Inspection
Inspect the air filter and the intake tubing leading to the turbocharger. Ensure the air filter is a standard paper filter and not an aftermarket oiled cotton-gauze filter like K&N, as these can sometimes allow fine dust particles to pass through, potentially damaging the turbo and engine. Check for dust accumulation in the intake tubing. A light oil film is normal, but excessive dust is a red flag. Also, examine the turbocharger wheel for excessive play or signs of damage, which could indicate wear or impending failure.
Oil Leaks in the Engine Valley
Check the engine valley (the area under the turbocharger) for oil leaks. Leaks in this area could originate from the turbo pedestal O-rings or the Exhaust Back Pressure Valve (EBPV) plunger in the pedestal. These leaks are relatively common on higher-mileage 7.3L Powerstrokes and should be addressed.
ESOF 4WD and Vacuum System Function
If the Powerstroke F250 is equipped with Electronic Shift On The Fly (ESOF) 4-wheel drive, test its operation, particularly with the air conditioning turned on. If, when engaging 4WD or turning on the AC, the airflow from the vents diverts to the defrost vents, it suggests a vacuum leak in the system. Vacuum leaks can affect various systems, including 4WD engagement and HVAC controls. While fixable, a vacuum issue can be a point of negotiation on the purchase price.
Powerstroke F250 Towing Capability and Practicality
My Powerstroke F250 is a fantastic tow vehicle. I regularly tow a large tent trailer, loaded with all our camping gear, including a motorcycle. Even with a substantial load and challenging conditions, the truck performs admirably. On our last camping trip, we encountered severe winds, but the F-250 felt incredibly stable and planted on the road. My family feels safe and comfortable in it, which is paramount. Plus, we’re getting better fuel economy than we did with our previous gasoline-powered vehicle while towing. It was even satisfying to see the truck maintain speed and power on inclines where other vehicles, not towing anything, were struggling.
The large towing mirrors are a huge asset when pulling a trailer. While some F-250s come with smaller, less protruding mirrors, these “monster” mirrors provide exceptional visibility when towing.
Here’s a picture of the truck loaded up for a recent trip:
I even managed to find a camper shell for free. While it might not be the most stylish addition, the shell adds significant practicality and secure storage space.
Conclusion: Is a Used Powerstroke F250 Right for You?
Overall, my experience with a used Powerstroke F250 has been overwhelmingly positive. With its legendary 7.3L engine, robust build, and impressive towing capability, it’s a truck that delivers on its reputation. If you’re considering a used Powerstroke F250, especially a 7.3L model, perform thorough inspections, address any maintenance needs proactively, and you’ll likely find yourself with a reliable and capable truck for years to come. Good luck with your search!
