Best Truck Ever!
I bought my F250 XLT 7.3 4X4 CC LB new in Sep 2001, 1 week after 9/11. One of the last 2001's built with every option less the Lariat trim (3 kids ice cream and leather seats not a good combination), dealer already had 2002's on the lot. Component date code stickers range from June 17 to July 30 2001. Took this over the 2002 model for the 0% 4 yr financing plus the $6,000 discount off the $43K+ sticker price. Having owned this since new with 8 miles on the odometer and 350K miles later I can state the following: The 7.3 is by far the most dependable, bulletproof engine out there provided you maintain the 3 "F"s: Fluids (Shell T6 since break-in), Filters (Fram Ultra Guard @ 10K mile changes with a FS2500 Bypass filter and fuel filter change @ every other oil change) plus clean water free Fuel. Service wise I've had a HPOP, 1 injector, 4 transmissions and 3 safety recalls performed under warranty (6 yrs 100,000 miles ended Sep 07 ). The 2001 4R100 was notorious for the 2nd gear diode clutch to fail and the factory single disk converter could barely handle the stock power. Adding tuners, upgraded turbos and injectors plus opening up the exhaust could easily add 150HP and 200LBS/FT of torque (400+HP 725+ TQ) which only accelerates the mean time to failure. As a credit to Ford they kept replacing transmissions for a $50 deductible (plus got a free loaner car for 2 days) albeit with stock parts that would fail again. I offered to provide a billet converter with multiple disks but they said if the dealer installed non-factory parts under warranty it would void the warranty in the future. The solution was to rebuild the transmission with billet shafts and increase the number of clutches in the gear packs. This is easily done by any reputable shop. My current trans has over 200K miles and shifts like new. While you're at it, upgrade to the 31 row trans cooler from a 6.0, factory part bolts right in with hose adapters. Another issue is over time the front steering play will loosen up and develop a tremendous amount of lateral play (slop). I installed a Red Head steering box which now has ZERO play. Not sure if this applies to gas trucks but the 7.3, 4R100 and transfer case weigh as much as some cars and almost all of it is resting over the front axle to free up payload capacity for the bed area. That is a lot of stress for those components and since diesel engines lack a vacuum source, they rely on the same power steering pump to drive the power brakes. If you are looking at buying a 7.3 here's is what to watch out for: Make sure all the service bulletins have been complied with. A VIN check through the dealer will pull up the service history. Warm up the engine, unscrew the oil fill cap and check blow by. Do the same with a flat sheet of paper and hold it 3-4" from the exhaust pipe and check for a pulsating exhaust plume. This can be the marker for a dead cylinder. Make sure you determine if the transmission had the 2nd gear diode replaced on 2001 models. On 4 wheel drive models with ESOF (Electronic Shift On the Fly) check the VACUUM system for normal operation as this can be $$$ to repair. Early 7.3 models also have a problem with the engine skipping when hitting a bump or pothole in the road. This is an easy fix caused by a loose connection on the driver side valve cover that connects to the electrically fired injectors. The newer valve cover gaskets corrected this. Check the turbo up pipes for leaks which reduce turbine speed and result in less power. The 7.3 is 100% dependent on positive intake pressure (boost) to make its rated power. At the stock setting of 525 lbs/ft @ 1600 rpm, this will easily pull a 28' 6,000lb trailer and gear over the Eisenhower Summit (11,300') on I70 at 65mph uphill in July. Finally, be advised the 7.3 was discontinued in 2003 due to new EPA emissions regulations. In simple terms the 7.3 is a dirty engine and with the exception of a small PCV hose, completely lacks any emissions devices whatsoever. This is WHY they can go 1 million miles between overhauls if taken care of. The great thing is: THE 7.3 ENGINE IS MAINTENANCE FRIENDLY AND CAN BE MAINTAINED WITHOUT SPECIALIZED COMPUTER SOFTWARE OR TECHNICAL DATA WHICH IN MANY CASES IS NO LONGER LICENSED BUT LEASED MAKING REPAIRS ON NEWER SMOG EQUIPPED TRUCKS ALMOST IMPOSSIBLE WITH OUT AN EXPEN$IVE $UB$CRIPTION. If you're like me and enjoy working on you vehicle, these are hard to beat and parts are readily available.
The 5.4 Triton motors suck they blow the spark plu
The 5.4 motor blowes the spark plugs out of the aluminum heads. Ford did not put enough threads in the heads and the steal eats the aluminum heads up
7.3 vs 5.9 common rail Cummins
7.3 fired right up no issue @ 6°F out side then went to start my dodge 07 with 5.9 cummins would not start two battery chargers and some time later finally got 7.3 still on its original build about 400 thousand miles 5.9 Cummins is currently one rebuild number 4 is 8 years Biggest thing I learned with the 7.3 is let it run for about 5 minutes before driving the transmission will thank you later need time to get the fluid moving
Ford makes the best trucks I’ve ever had! My old girl is a V6 has engine with 248,000 miles on her and she’s still running strong and trusty! She’s never had any major work done to her. All the maintenance has been the usual work every vehicle requires at certain mileage. I’ve had this truck for 11 years and she’s still my reliable trusty steed. The gas mileage is horrific but who buys a truck for gas mileage? Not me. This truck is used to haul horses and cattle as well as being a daily driver. It is perfect for me and my 4 dogs. Couldn’t be happier with her performance over the years!
This truck is extremely reliable.
This was my dads ranch truck and daily driver. I have driven it off and on over the years since new. It runs just as well now as it in 2001. Just has a few rattles here and there but still turns heads wherever I go!
Worst truck I have ever owned. It has blew out 5 p
Junk keeps blowing out spark plugs. Don't know why ford did not thread the plug holes all the way down. Should be a recall to fix this problem
Best truck ever built
I have the 7.3. Easily the best and most reliable truck I've ever had. Good power for towing and hauling. Just needs normal maintenance and keep the fluids changed and it'll run forever. I'm keeping mine until the wheels fall off and then I'll try to find another one.
Bought an '01 used in '09, and still love it!
I'm a rather large guy, 6'4 and 250ish pounds. This truck is comfortable, reliable, and if you take care of it from the beginning, it will last forever. There are other 7.3s in my area with over 1,000,000 miles, so I guess that counts for something.
Tows like a champ.
I bought this truck in 2004 with 70,000 miles on it. 15 years later she has 340K miles on her and continues to hum down the highway. I did replace the transmission at the 150K mark, but have had no other issues outside of routine maintenance. Tows like a champ. Really hesitating letting her go.
Best Truck ever!
This truck meets all my expectations. I love everything about it. I so glad I got it. Low mileage. Best Ford diesel engine ever! One owner who took excellent care of it. What more could you ask?
