Ford truck diesels

Did Ford ever us IHC diesels in their trucks? I thought they always used Cummins, but someone said they also used Internationals.

Thanks for your replies.

In the 80s, 6.9 and 7.3 were IHC

The 7.3 diesel was IH/Navistar not sure on the old 6.9

Thats all they used until the last ones were a dorf design . And yes dorf did own a very small percent of cummins and so did Case but after the fiat merger they started using a cummins clone

The early Fords used Navistar/IH. Ive seen Cummins in Fords but I dont think it was factory. Dodge uses Cummins in their pickups.

The 6.9 and 7.3 IDI were used by Ford and IH truck. There were some 1 1/2 ton Ford trucks that did use the Cummins 6BT, neighbor has a Ford dump truck with the 6BT.

Over the years, Ford used about everything under the sun. The local feed stored used to have a Ford truck with a Detroit Fuel Pincher engine. That one was a lemon.

The V8s until the 6.4 were Navistar engines. The 6.7 was Fords own design. The 7.3 Powerstroke was developed by a Cat and Navistar collaboration.

The larger trucks used some different options including Cummins and Fords own I6 diesel engines.

Are we talking about HEAVY trucks or MD trucks or "pickup trucks"?

You look closely at a 6.9-7.3 and at the 404-446 and it is the same block one with gas heads and one with diesel heads with OLD 460-560 style per combustion chambers with GLOW plugs . And a 404 two bbl will out pull it .

ford 6.9 diesel and ford 7.3 diesel and ford 6.0 diesel and ford 6.4 diesel were IHC/navistar powerplants. I always thought these engines were good power plants, they had steel reinforced pistons (cummins is just aluminum slugs) navistar had roller cam, (cummins had and still has flat tappet) and furthermore the 7.3 powerstroke was the first common rail diesel pickup truck engine in 1994 which EVERY CURRENT PICKUP TRUCK DIESEL FOLLOWED SUIT (eventually) On top of cummins having a conventional ring land and navistar used a tapered ring land. I have owned, used, repaired, and drove several of each. I know what I would purchase without any second guess in quality, reliability, and durability. I have never known of a cummins factory installed in a ford pickup. I used my ford to rescue a dodge cummins from the mountains recently. THE BRAND NEW AxLE U JOINT EXPLODED and locked the front right tire up. hadit have been a ford superduty, it would be factory equipped with locking hubs. I could unlock the hub and drove it home. Instead it is a way more dependable and reliable design to have constant mesh 4x4. NOT.

Ford offered ALL the MFG of diesel engines when ordering . Ya could get a Cat , ya could get a Detroit , ya could get a Cummins on the Hd line up on Med duty it was Cat Cummins Detroit and Ford , On Pick ups it was I H on the early ones A make over 404 -446 gas conversion to diesel. . If you ever worked on the 404 -446 gas the blocks were cast out of the same mold as the 6.9 and 7.3 have the same dist hole rough casting just not machined for the dist. and a add on timing cover for the injection pump . They followed GM in converting a gas block into a diesel block .

I was thinking of pickup trucks with my original post. 150, 250 Did the King Ranch version mean anything special in engine installed?

Great replies - thanks.

7.3 Powerstroke is not true common rail, it is HEUI injected. Yes, all the injectors are fed from a common fuel galley in the head, but that galley is low pressure fuel. Common rail injection means the fuel feed rail is under full injection pressure from a separate high pressure pump. The gm was Duramax the first common rail light truck diesel.

Yes they did and I think it was initially. My take on it was that they wanted to enter the market with a winner and felt that IH knew how to build a diesel. No telling what went on in the selection process but IH won.

The 6.0 was complete junk. It cost ford a billion in recalls and repairs. The 6.4 was a little better. The 7.3 was not a true common rail engine. Your using one example of a dodge ram breaking down to label them all as junk. Your such a die hard ford fan that you will not accept the facts. The Cummins 5.9 and 6.7 are the only heavy duty diesels installed in a light duty truck. Some super duty fords used vacuum actuated front hubs which could be a nightmare. In a industrial/heavy duty application, the Cummins engine will outlast anything. I do not see any ford V8 diesels in farm equipment or construction equipment

The 5.9 was originally developed for Ford but Ford wanted to biuld the engine and be the only one that used that design. Ford did end up using the 5.6 in there F650 and up trucks.

The 6.9, 7.3 IDI engines along with 7.3, 6.0 and 6.4 Power Strokes were all I-H engines
The 6.7 is supposed to be a Ford designed engine
Ford did install a Cummins 4BT in the F-250 in the early 2000's but that truck was only available in Brazil
King Ranch is a trim option and uses the same engines as any other Ford pickup

There was actually two, unrelated, 7.3s in succession. The first one was a PC motor, a bored-out 6.9 with deeper main webbing and larger bolts. This 7.3 was factory turbocharged for a short time before the totally new, electronic injection 7.3 debuted.

I went to buy me a new pickup in 1999. I looked at ford 250 Diesel and Dodge 2500 Diesel. I got a brochure on each. When I saw that ford put the 7.3 in the 250,350, 450, and 550 but the 650,750 both had the 5.9 Cumins the same as th Dodge 2500 that made up my mind for me

I remember a Ranger pickup with a turbocharged Isuzu 4 cylinder diesel. It was at the local hardware store, I waited until the owner came out,he was happy to raise the hood and show me the engine. He said it was not used in very many Rangers but it ran well and had enough power, the great MPG was a bonus.

International did know how to build an engine but why didnt they use an inline international engine they wouldve put the hurt on dodge if they had or ford inline Diesel engine they had a good engine

Power Stroke = Power Joke, Power Junk, Power Struggle......

I spent 38 years in a Ford Dealership. I never trained to repair the diesel engines. I flat out refused. The 6.0 and 6.4. were the worst pieces of crap that Ford ever sold. And having to remove the cab to do repair the 6.4 was just poor/stupid engineering.

I have been retired for a few years. I can't remember for sure now but I think the biggest problem with the 6.7 was cats getting in the radiator fan shroud during cold weather. It made an awful mess.

There was also a powerstroke in the F150, 3.0 V6, it's a Ford engine but no longer available, 2018-2021

The old Ranger/Bronco II diesels were a Perkins design/Mazda built n/a 4cyl (4.135) for 83-84, and a Mitsubishi turbo 4cyl (4d55) for 85-86 or 87 on Bronco II. Chevy was who partnered with Isuzu and they still are.

The 5.9 B series Cummins was not designed for Ford. Ford had already committed to IH in 1981 and the Cummins B series was designed in 1984.

The 5.9 and later 6.7 was an upgrade or standard diesel engine in Ford med duty. It seems like Ford realized the light duty characteristics of previous powerstrokes. The latest Ford designed 6.7 powerstroke is offered in Med duty since 2016.

6.0 ford diesel complete junk? really? Why? What did it do? Did you own one and have it just constantly in the shop? did you ever repair a broken one? Did you ever tow one from the side of the road just completely destroyed? The 6.0 diesel was known for cylinder head problems. Meaning problems related to the cylinder heads. Injectors.. In the cylinder heads, head gaskets, Lets fairly compare DODGE CUMMINS from same year... 2003-2006 (FIRST COMMON RAIL CUMMINS) these engines had cylinder head casting problems that dropped the valve seats from the head, and often ruined the piston in that hole. Don't argue this point without an engine machine shop that disputes my claim. I guess Engine machinists seem to know all engine failures and weaknesses and have to fixit. Ask me how I know. Guess what, cummins 5.9 hadvalve seat failures ruining engine, in droves. If I have to I may be able to locate receipts and machine shop statements from a tremendous amount of these CASTING FAILURES. Findme a low mileage 6.0l Ford with a CASTING FAILURE in 10% ratio to the cummins 5.9 commonrail trucks. Head gasket isnot a casting failure. Injector is not a casting failure. Valve seats dropped from cylinder head is a casting failure. A failure at the foundry. Ford 6.0l diesels had a huge cooling system oversight. The radiator cap was a $0.99 piece of junk that failed every 6 months and I have tested 6.0 radiator caps for nearly 20 years, they have never tested good. always fail. Always. That means that coolant boils and steams in the cylinder heads under load, creates hot spots, and causes failures due to steaming coolant. I don't really care if anyone agrees with this. Cummins casting problems go all the way back to the ntc855 that leaked coolant down the side of the bock because of counterbore issues through 1980s and early 1990s. Tear down a cummins and tap the middle cylinders with a ball peen and coolant sprays from between liner and block. If you thinkcummins builds a absolutely perfect product, I guess I have a few I would love to sell you. Unfortunately, if the ford 6.0l was maintained with proper cooling system pressures, proper cooling system maintenance, and proper coolant... They were by far the most reliable vehicles I have ever had the privilege of driving. Maintenance is key. However, No amount of maintenance can fix poor castings, NONE.

Andon top I have seen several 7.3 powerstroke diesels mixing oil and coolant. The engines were condemned as being garbage. I bought the trucks and resealed the oil cooler ($50 repair) and those trucks are still running. saw one today on a construction crew putting new gas pumps in at the gas station I use. And, let me guess, those trucks that are still running today with a $50 repair, were hated by some mechanic shop and the owner for being a terrible vehicle because they were mis diagnosed. I hate to say it but I am afraid that the 6.0l fords were terribly misdiagnosed and improperly repaired. causing ongoing failures and bad reputations on account of incompetent technicians.

I am always amazed by the passion surrounding brand loyalty. "My brand is best." "My team is best." "My party is best." SMDH

I agree with a lot of your post. I also saw the demise of the mechanic in the early 2000s when it came to diagnostics.

I could go on for days discussing the pickup engines over the years, however, in my line of work, oilfield, I have found my cost per mile is better with Ford than GM or Ram. I bought over 40 of the Rams and 60 or so GMs, and needless to say Im back to 100% Ford at this time. As far as Cummins goes in general, the bigger engines really show their true colors. The 15L and 50L engines I have of theirs, over 100 of them, are terrible.

Didnt they cost Ford 1 billion dollars in recalls and repairs? I see way more 2003-2006 Dodge Ram 5.9 Cummins still running in my area. You cant give a 6.0 away, no one wants them. Ford 6.0 engines have created a lot of business for aftermarket companies. 855 and N14 Cummins were excellent engines. Get your facts straight kid
