I love my 99 7.3 F-250! No major problems, I have nearly 600,000 miles on it. Best truck I ever owned.

[@westernstartruck2528]

In Newfoundland it’s impossible to find a box for any fords 10 to 15 years old there absolute rust buckets from our wonderful salt we use. I have a 05 f250 that looks like a banana and I’m looking at buying a 03 f350 7.3 dulley that will be getting a flat deck if bought because of rust issues. $3500 with 300,000 kms it runs and moves so hopefully it is a good choice for hauling a bit of wood and maybe pushing a bit of snow. Thanks for sharing your knowledge it will surely help me in my purchase

[@NoWay-xu1ie]

Great video, lots of good info. I've owned a 2001 7.3 for over 7yrs. With 166k miles. That has had some mods. I've done. Including a built trans. We mainly use it to pull a 13k 5th wheel south for the winter. It's a rust free truck. So I plan on keeping it till I die. A recent problem was the engine stalled . And restarted with a engine miss. It has a TS6 chip that has custom tunes. At first it showed a ICP 1280 code. That showed up on my bully dog, that is just used for gauges . That I checked out and was ok. In Harlingen Texas I found a shop that could read the codes . Because of the TS6 CHIP ,they could not access the PCM . They had to remove the chip and was able to pull codes and do a buzz test. No problems. Removing the chip cured the engine problem. I forgot how much different it was running without the chip. Brian at BTS is sending me a new chip. It has been a great experience dealing with a reputable business. Something you won't get on Amazon. I think my problem could be difficult to diagnose for someone that has not had a lot of experience on 7.3s . I've had a bad connection in the valve cover that acted the same way. That I found checking ex. Manifold temp. This time the temp was the same. Anyway FYI on possible chip problems.

[@mrinspector2206]

you can keep these quieter by running shell rotella oil, the weak point on stock 7.3s is the 4r100 trans. Upgrade with a larger trans cooler and an aftermarket condenser fan to get longevity

[@timothyholt2934]

Yes they are week jest spent 1500$ on mine

[@Fatenarr]

Larger trans cooler is the first thing I would do if you buy one of these. The stock cooler is a joke. Get a 6.0 tranny cooler and it’ll never go above 150

[@paradiselandscapes535]

Rebuilt the Automatic transmission in my 1999 F250 super duty 3200.00. The shop put in a high performance Shift pack.

[@ajcather2400]

Or get the zf6

[@stevenwolfe9085]

No the real weak point on the 7.3s were the old E40D transmissions and little transmission coolers. a 4R100 has much better internals and parts and if you add a deep dish pan and a large trans cooler from a 6.0L Powerstroke 2.5x more surface area than the 7.3 Trans coolers.

[@johnriise9506]

We have a 2000 F-350 4X4 four door Dually Super Duty, Power stroke,. with a little over 200,000 on it. We bought is 11 years ago, we bought it from a local farmer that had towed a goose neck stock trailer which he almost never unhooked it., he just wanted a new Dodge . We paid 10,000$ for it.. The pick-up was super clean inside and out. The Pick-up had no exhaust, It ran great but it was just to loud. We bought the Banks exhaust with a muffler plus the Banks big air intake. Our engine builder Bob Cram (Ridgecrest CA) said we got a good deal, but to get rid to the bully dog set up, Bob said it will bite me. The pick-up had three gauges one trans temperature , turbo boost, and turbo temp. I hit a snow pole and it took my right dually fender off, to find a new or used one was out of the question . My wife found a 9'6" flat bed for 600$ with tool boxes under and two large tool boxes on top of the bed. I bought a sand blaster for the bed it came out like new. I added new LED light, and paint. We tow our 24' fifth wheel camp trailer, We have no problem climbing the large hills here in Northern Nevada.. We are in our late seventies , and just love the Super Duty . We have done most of all which Bill Hewitt has recommend, I enjoyed your talk about the two ford pick-ups..... Thank You !

[@dirtydynadepot5126]

My 2002 has been the best pickup ever. Besides heater core issues. It’s been perfect. Went to a bigger heater core piping and seems to have fixed my problem. It was caveating in the small pipe elbows to much pressure. Had to find bigger QD fittings but haven’t had an issue since. Thanks for the video I’m a late viewer.

To me the interiors on these years are some of the best ever made..with half ass care they just last..no cracks little to no fading either..I have a 2000 model F250 4x4 ...250,000 miles and I rebuilt the front end but it earned that..I’ve replaced the water pump alternator and radiator all normal stuff that’s gonna go bad..I’ve replaced the injector harness on both sides because passenger side went out...other than that IMPECCABLE...u couldn’t pay me to swap for a new one!!!

I’ve got a 99 7.3 I got about 3 years ago w/ 187k on it. Since then I’ve replaced the CPS, ICP sensor, water pump, thermostat housing, radiator, glow plug relay, batteries, A/C system, and installed the 6.0 transmission cooler which I highly recommend. 235k miles on it now and still running strong.

Early 4r100 equipped trucks had torque converter issues. Primarily a 99 model year issue. Likely most have been replaced at this stage in the game. They were very noisy when bad...even noisier then the old 7.3 when at idle! So, they are pretty easy to spot. Lol

I am the original and only owner of my 2000 7.3 PS, 2x2 extended cab truck. The only repairs in 22 years and 182,000 miles so far has been the starter and alternator to which DB Electric was able to send what I needed, replaced the batteries a couple of times now. I did the brakes all the way around a couple years ago, I also did a SUPER coolant back flush because the 7.3s usually had a A LOT of casting sand in the block. I flushed it about 6 to 8 times over several days, put a new de-gas tank, belt all the hoses, added a water filter, put a NEW water pump and put the red extended life Chevron coolant. When I service the 4r100 trans I always 1...do it myself because there is a drain plug on the torque converter to drain it as waell as drain and remove the pan for a new MOTORCRAFT filter to be installed. The swing out cab doors will have the cable ends go bad, esay fix,...several guys here on YT show how to repair, and the metal cable repair parts are like $8 to $10 on ebay. Yup, this was a long right up, but this is EVERYTHING I can remember repairing in 22 years. I still have the original U-joints...original steering link and ball joints. And those things I said would get replaced in 3 years because there were no grease fittings...WELL I WAS WRONG. This has been and is a great truck.

Love the front leaf's and straight manual lockers. It actually has a much shorter turning radius than the wife's F150. The 99's had trans overheat issues, in 2000 they added the trans oil cooler. Yes, when it was 2 months old the cam sensor failed, thankfully under warranty.

[@tedenderpalmer6550]

Check for rust along the beds front beam just behind the cab, crawl under and take a good look. Next check for exhaust leaks around the turbo, shows up a suit on the fire wall. Inspect the spider for cracks at the flanged. When replacing turbo mount o-ring seal some mechanics will swap the turbo up pipe to turbo clamp with the spider to intercooler clamp this will crack the spider. The big clue is the v-band clamp that looks like a hose clamp will not be on the spider. Listen for turbo whine on acceleration, if you don't hear it there's trouble.

I have an 01 Excursion 73 we bought it was 75,000 miles on it. We’re just over 101,000 miles on it and I have probably put 12 camshaft positioning sensors in it. I took the time to clean the battery terminals very well, one day and had no shut off problems for a year. But I’m back into having it momentarily. Shut down while driving and usually towing a trailer. I’ve been told it might be electrical. A friend of mine cleaned out his fuel tank and said there was a bunch of crap in it. He cleaned it out and has not had it shut off on him in five years. I have a hydra chip in it for fuel economy. Curious if you have any ideas? Kyle

[@tyroneparsons1086]

240,000 miles 2002 7.3 2wd I’ve had it for over 100,000 miles I had to put three grand into redoing the front end because of normal wear and tear that included a 2 inch leveling kit, normal matinence and new headers. It runs like a champ. I tow about 6000 pounds 4-5 times a month, and it’s constantly full of tools as it’s a work truck. If you find one of these trucks that has been respected that it’ll last year forever. Even if you have to dump 3 to 6 grand into a new front end or other basic maintenance issues you have after 150000 miles you’re basically getting a new truck at that point. That still has a longer life left in it compared to newer vehicles today.

I'm about to purchas a 2001 F250 with the 7.3 in it... even though it has 200,000 miles on it I am still very excited!!

[@magicmiles6985]

99-03 F250’s had Dana 50 front. They switched back to 60 in late 03. Excursions always had Dana 50. Great video, though!

I got a 1999 7.3 late 527,315K as of yesterday I hate oil leaks but other than that she runs like a champ never has let me down such a reliable engine no rust expect a few specks in weird spots by the window wells and little surface on the frame

[@spencerbrown1071]

If you see a Super Duty with fender flairs like the one in the video, look behind them... probably rust! I wanted to put some on mine but I don’t even have anything to attach them to. VERY common on northern trucks. I live in Indiana. Also look for the rear diff cover to be seeping diff fluid, another very common issue. If it’s a northern truck, check your bed mounts. And like wade said. Definitely check where the dip stick goes into the oil pan. If it’s rusted or looks bad, you’re gonna have to pull the motor to replace the pan and fix the issue. It’s also not uncommon for the torque converter on a 4R100 to go at the 200,000 mile mark.

[@bch5513]

For TC ..Put a triple clutch billet in and keep rolling. Main thing that tears up 4R100 is heat. The cooler on these trucks are tiny. Change fluid every 30k if you tow a lot.

[@spencerbrown1071]

Brian Hanks yep. I put a triple disc converter in mine and a deep trans pan that added 7 quarts of capacity when I rebuilt mine. Runs MUCH cooler now. Next is to upgrade the cooler itself.

[@bch5513]

Spencer Brown If you’re on a budget you can get a true cool Max for about 129 bucks. Not as fancy as a 6.0 cooler but I have had zero complaints about mine and I keeps my tranny 40° cooler. Put in within 30 minutes

[@liveitlikeitloveall2746]

Yeah I've had to replace the torque converter or flex plate ..at around 230k .. I'm going to have to check the dip stick tube, because my 99 is rusting out like a 1980 Toyota.. lol It's bad.. It runs like a damn champ though.

Thoroughbred Diesel So I am actually doing a trade tomorrow, I am trading my 2002 Dodge ram and a 1996 Jeep Wrangler and a car trailer for a 2000 7.3 L crew cab. I’ve done a bunch of research on them, but this was the best information that I’ve gotten yet. I’ve been really really picky about what I want and I have heard that this is the best diesel engine ever made. Thanks a lot for your video and if you have any advice, feel free to let me know LOL

[@crossfadered5474]

I am buying a 2003 Excursion with the 7.3l from my uncle. I have been working on it for a while and one issue I had found was the window and radio would stop working at random. They weren't getting any power at random when starting and driving and would turn on and off together. I found the problem after looking at all of the normal areas you would think the problem was. If anyone has this issue there is a shared relay behind the dash that can sometimes get moisture damage from bad windshield seals. Once replaced the problem stopped.

[@bluetwo7282]

Good to know, I think I have same issue with windshield leaks on my 99 Super duty.

[@williamschwenz59]

Love love my 99 f250 it's got the 7-3 leader but it's only two-wheel drive I nickname my truck T-Rex because t-rex only had little arms but he was a beast that's like my truck 2 wheel drive but a monster power 7.3

[@wrightswildlifehabitatmana8486]

Transmission cooler is the weakest link in the power train. I serviced it regularly and had no problems 264000 miles but I was starting to pull 23,000 lbs. so I replaced it and got a Mishi Moto 6.0 transmission cover and replace the original factory with that cool. Other than that I’ve had no major problems with my late model 99

Isn't that only with the automatics?

These trucks are bringing big bucks, I just got offered 30k for mine, 01 250 superduty fx4 kc sb NO RUST, ANYWHERE. and told them nope! The toyota dealer seen it and offered the new supra if I gave him the truck and 15k I took that as an insult. 158k miles, hydra chip, pillar gauges, cold air, 6.0 oilcoller swap and magna flow downpipe, back which I did for towing the camper. I love it,sold my 2000 10yrs ago and kicked my self till I found this one. best trucks ever.

[@rddragon46]

I currently have two 99 7.3s I’ve spent a lot of money fixing issues that were caused by previous owners neglect. Both trucks still had their original ICP sensors and they were leaking. They both start easy on a 10° day. My best advise, only use Ford fuel filters and air filters! My 250 tried to suck a cheap filter into the turbo once.

[@bch5513]

Switch to 6637 and don’t dust a turbo. The factory filter boxes are notorious for leaking and sucking in contamination.

In cold weather starting I found that the relay for the glow plugs every couple years on the one I have goes out and I have to replace the relay and that’s all it’s a matter with it

[@RunningAPaint]

love my 01 7.3, but of course, I've replaced some stuffs on her... the short list includes fuel injectors, glow plugs, u joint, front axel, the lock out hubs, ball joints etc. However, it was an investment of about 13k for an engine, I believe, will be my last truck. With only 199k on her and the preventative maintenance ie: front and rear differentials, maintaining clean oil and filters and such, I don't ask much of her. Thanks for the information in this video. I came looking for information to recharge my AC lolz and got a nice reinforcement of what a great truck I really do have.

up north watch out for leaky windshield. if your glove box is getting full of water your GEM unit will be next. Been there... twice.

[@jordanmjohnson_]

I had an 01 7.3, and absolutely loved it. Only had a couple things wrong with it, I did have my Overdrive light blinking at me, and had a small electrical problem with it. Turned out replacing the batteries fixed that problem. Although it was a heart wrenching sight when I first saw that light blinking, I was relieved when it was just the batteries. Also when I was at a complete stop, then accelerated, I had this clunk that came from what seemed the rear diff, I had it checked out and was told nothing was wrong. So I didn’t worry about it! Lol if anybody else has that problem and knows what it is, I’d love to hear what you have to say 😂 other than that, these trucks are solid.

[@stephenlane7951]

Very possibly a drive shaft u-joint.

[@grubb910]

Ive seen some trucks experience a clunk because of driveshaft slip yokes binding, and also leaf springs having a flat spot where the usually ride. When the axle torques on acceleration, it pops off the flat area, and makes a clunk. Just some ideas.

[@straycat62]

Check rear drive shaft slip yoke. It can bind. Remove the 4 8mm bolts at the rear most U-Joint and drop the drive shaft. You should be able to feel if it can slide in and out like that. If binding look up how to fix. Its easy to clip rear metal band on boot, grease splines and zip tie the boot back. Check the carrier bearing. They do get worn. Leaf spring idea below is interesting too.

[@bluetwo7282]

Have u changed rear differential oil ?

[@youknow9328]

Speed sensors there are two. That’s usually what does that and causes that intermittent od light. Was the issue with one of mine.

Dang, you sure know a lot about the Ford 7.3L diesel even though it isn't your strong suit. For the record, I have a 2000 F250 diesel with 110,000 on it. It's been real good. I haven't had anyone offer me $30k for it yet.

[@johngoodbred1945]

Nice job on the 7.3 issues. Many of us carry a spare CPS in the glove box. Had a recent problem with electrical system. The power to the computer and everything in the passenger compt goes from the battery through a connection point on the driver side fender well. The connector finally gave up and broke off due to corrosion and the entire truck went dark (no PCM, horn, windows, no starter, etc.).

What I find most guys with Diesels they up the power and try to pull big 5th wheels then get upset with the transmission burning out. You can't do both add power, and put lot of weight behind it unless you upgrade the transmission. SUV's like the Excursion less likely someone pulled a heavy trailer with it probably wasn't torn up.

[@hustleeveryday5852]

I own a 1999 F250 7.3 and the issues have been minor, though sometimes it seems like they never end, I have to remind myself that the truck is 23 years old. Every issue I have been able to fix on my own, from transmission to electronics, and I'm certainly no mechanic, the issues just haven't been all that difficult to fix. My truck has 260,000 miles, original engine and turbo, and I can still hit 30 pounds of boost WOT. I also own a 2019 Nissan pathfinder, and that thing has been in the shop more than it's been in my driveway. Hell, that thing's at the shop now!!! For 23 years and 260,000 miles, it's a beast. I would say that most people can feel pretty comfortable purchasing a 7.3 turbo diesel. They don't make them like that anymore, that's for sure!!!
