Is the 2002 7.3 Powerstroke a good engine?
The 7.3 PS is a reliable motor wrapped in a 20+ year old body. You'll need constant maintenance from here on out to keep it up and running, from sagging door hinges, fuel lines, steering column mechanism, and eventually the transmission will crap out.
How many MPG does a 2002 Ford F250 7.3 get?
Based on data from 18 vehicles, 1,953 fuel-ups and 593,503 miles of driving, the 2002 Ford F-250 gets a combined Avg MPG of 13.34 with a 0.17 MPG margin of error.
How long will a rebuilt 7.3 Power Stroke last?
Remanufactured diesel engines are built to the same, if not higher, quality than a new diesel engine. With proper care, maintenance, and a break-in period, the average miles of a reman diesel engine is anywhere from 200,000 to 400,000 miles (320,000 – 640,000 km).
What is Ford's worst diesel engine?
The 6.4 Powerstroke came after the 6.0 Powerstroke, which was widely panned for its problems and poor performance. The issues with both of these engines eventually led to the end of the working relationship between Ford and Navistar and led to Ford designing its next diesel engine in-house.
What is the life expectancy of a 2002 7.3 Powerstroke?
Powerstroke Engine Average Life Expectancy:
7.3L400,000-500,000 miles. 6.0L200,000-300,000 miles. 6.7L200,000-300,000 miles. 6.4L150,000-200,000 miles.
What year is 7.3 the worst?
The worst years
Model years 2001 to 2003 were the worst for the 7.3L Power Stroke. These engines were plagued by issues ranging from excessive noise to failure of the camshaft position sensor and fuel leaks. Beginning in 2001, the 7.3L Power Stroke developed a reputation for excessive engine noise.
What is the main problem with the 7.3 Power Stroke?
An issue with the CPS is one of the most common problems on the 7.3 Powerstroke. On the Old Body Style, the tachometer will move while cranking if the CPS is good. If it doesn't move, then the CPS is the problem. Fortunately, a new CPS for the 7.3 Powerstroke is one of the more inexpensive diesel parts to replace.
What is the most common problem with the 7.3 Power Stroke?
Check the Old Body Style (OBD) by watching how your tachometer moves while cranking. If it moves, it indicates that your CPS is in good shape. If it is not, however, this may be a hint that you should replace it. The cam position sensor is the most frequently encountered issue on the 7.3L Powerstroke.
Which 7.3 Powerstroke year to avoid?
2001-2003 Model Years.
What is the most reliable year of 7.3 Powerstroke?
The 1999 7.3 Powerstroke stands out as the best year for this engine. Key advancements came in the form of reduced NOX emissions and the introduction of upgrades like the new 4R110 automatic transmission, air-to-air intercooler, ZF-6 speed manual transmissions, and various other improvements.
