not to take away from this site but, www.powerstroke.org is a great site for the PSD's.

I have a 2002 7.3L I have 154,000 and I just follow the maintenance guidlines in the owners manual. That is for the routine maintenance.

It would be hard to follow the owners manual because I am not an owner. That's why I'm looking to PSD owners for things to look for as a prospective buyer

Check and change the oil reg. Change fuel filter reg. Do normal cooling system flushes. When to do these depends on how you use your truck. I change my oil about every 7500 miles. Fuel filter twice a year. Cooling system every 3 years. You might also want to run some fuel conditioner once in a while. I carry anti gel additives in the winter. You might also want to carry a spare crank sensor as they have been know to fail and leave you stranded. I have only had one fail in 130,000 miles.

oil change every 5,000 miles, fuel filter every 10,000 miles, air filter every 10,000 miles, trans fluid every 30,000, diff fluid every 75,000, coolant flush every 30,000, in cab air filter if applicable every 30,000 miles. I hope this helps you out.

I have 154,000 miles on my truck the only major problems I have had is the transmission. But then again when you abuse them they break.

GNJEEPN that would be Cam Position Sensor (CPS) and yes I have a spare in my glove box with the 1/4 inch drive ratchet 6 inch extension and 10 mm socket. Because that is all that is needed to use to replace this sensor.

You better add another 3 quarts to that 12 to make 15 quarts. As that is what mine takes every oil change.

O average 21-22mpg with my everyday driving. Mileage on a diesel is not that bad. If I was looking for a new used truck I would be looking for around 100,000 miles with not alot of major maintenance. Being your looking at the 7.3L that would not be to hard to find. Now if it was the 6.0L that would be a different story as the 6.0L had issues with the EGR cooler, EGR valve and turbo.

I have had a 02 F250 7.3L and now an 02 Ex 7.3L. I do what he said,

Check and change the oil reg. Change fuel filter reg. Do normal cooling system flushes. When to do these depends on how you use your truck. I change my oil about every 7500 miles. Fuel filter twice a year. Cooling system every 3 years. You might also want to run some fuel conditioner once in a while. I carry anti gel additives in the winter. You might also want to carry a spare crank sensor as they have been know to fail and leave you stranded. I have only had one fail in 130,000 miles.

Plus vist www.thedieselstop.com they have answered every question that I have had so far. Front axles like to eat ball joints and wheel bearings but if you do the work yourself it is not that painful. I have done pads and rotors on both of my trucks as well. Turn the factory ones before they get two bad they are not very thick anymore.

I put new greasable heavy duty ball joints in mine about 70,000 miles ago. I haven't had any problems since. I grease them regularly with the weight off the joints.
