How to change your 7.3 injectors

[@TheRrevn57]

Here is the secret to starting your motor after you have installed your injectors....MAKE SURE YOU HAVE FRESH BATTERIES! You need maximum cranking amps to force high pressure oil and fuel into the the injectors. If your batteries are too old forget it. It wont work. It cost me almost $400 for two batteries but I got my motor to start and it was worth every Penney....good luck.

[@MrFlirtnwdisaster]

A couple of things I noticed, 1, Why all the trouble turning the engine to remove liquid from cylinders. All you have to do is remove the plugs as shown and it will drain the oil back into the pan. Pull the drain plugs on the front drivers side and rear pass side and drain the fuel. Absolutely no danger in hydroing one of the cyl.

[@CodytheCarGuy]

It can be a little intimidating but its not really that bad then again ive done a bunch of them lol And no problem , the new videos im working on for the 7.3 are way better its more like a video manual and in HD too , ill be covering the 7.3 from a-z for everyone , well back to editing for tonight's uploads

[@PatrickBaptist]

Good video, you can just pull the fuse on the fuel pump OR just unplug the fuel pump at the connector at the pump, won't work for OBS trucks though, unless you are like me and do the e-fuel conversions. Just lay a rag over the head and do it with the glow plugs out, oil doesn't go everywhere that way.

[@CodytheCarGuy]

Yes you have to turn it over at least that many times sometimes more and still go to crank it as easy as you can , when the injectors come out all the fuel and oil in the rails go straight into the cylinder

[@campuscab]

[@CameronAudet]

(diesel noob here) does turning it over by hand, just drain the fluid? should you do an oil change after a full injector replacement? How is the fluid draining on a crank, seeping past the pistons?

[@tristen8089]

thats what i was wondering i did mine the way he did it and its making me scared cause it hasnt bled off yet

[@garigney]

I used a vaccum pump attached a steel tube ran down into cylinders to drawn out 98% oil and fuel from cylinders. THEN on on start up just bump starter few times slowly with a few sec between bumps,, when reasemeabled work great for me.. Hops this may help some one..

[@dsruddell]

good idea. if you dont use a remote starter you can send even more fuel and oil in. also if you pull the back injector first the fuel and oil rail will drain in the back cylinder. leaving the other 6 cylinders pretty dry.

[@vapeking5733]

guy at the ford dealer said to leave the key off remove the glow plugs from all the cylinder that you worked on and jump the selonoid 2 sec at a time till motor makes 3 full revs around o and i forgot only if you going to change the oil and set the valve cover on so u dont make a mess if not pump out. but at the dealer they always change oil if they remove the covers

[@MrTackleberry79]

Same way I change the oil on the top end. I use a copper tube though, less scratchy.

[@user-dn6qy1ou1f]

@@MrTackleberry79 no need to change the hpop oil. It recirculates into the engine almost immediately

[@CodytheCarGuy]

No if you take the glow plug out the diesel in the cylinder will go into the fuel, but if you have one or two really full and your changing the oil anyways then you can just take the glow plug out but you still will have to turn it over by hand . if you take it out and turn it over by key it will blow it all over the place and make a big mess. Sometimes when i get to where it wont go i simply turn it back some and keep trying, and the injector bolt i just snug good its a in pound bolt

[@YankeeinSC1]

@ 7:55 you edited out the part where you turned the key on... didn't you?

[@CodytheCarGuy]

The reason you DONT want to do that is because your cylinders are full of liquid and well you cant compress liquids so that means hydrolock which can bend and break rods so you can turn it over by hand to get as much out as possible or take out the glow plugs but that can be messy and a oil change after will be needed due to diesel will be draining back to your oil pan. And thanks for the compliment on the video the new ones coming out for the 7.3 are 10 times better and in HD now

[@wallacehough6708]

What about a vacuum pump to suck out the fluid

[@CodytheCarGuy]

well there is two parts of this, one is actually taking apart your injector and then cleaning and then putting the new nozzles in which can take some time, now then there is actually changing the injector and i can do it in a couple hours per side but not everyone is that fast. And if you already have mods done then bigger nozzles will make a difference, see right now you can add all you want but you are still stuck with stock holes same as changing jets in a carb, more work to motor bigger jets

[@TheRrevn57]

Thanks . 2 thumbs up.....what happened to tork specks?

[@CodytheCarGuy]

there is also a plug in the back of the head that helps drain the heads into the oil pan,the glow plugs out will only push the fluid up but not really out unless you turn the motor over w the starter which can make a big mess if you dont sit a towel over the head. I do it by hand then lightly w the starter until im sure it turns over easily

[@CodytheCarGuy]

well if its 50 hp tips or less you should be fine but 75hp and above you need major tuning, exhaust mods like bigger down pipe etc. Last i knew swamps does not have a extrude hone machine so hes getting those performance nozzles from someone else. Dont get me wrong i like the guys from swamps ive talked to him several times but we talked about test stands for the 7.3 since i built my own stand, hes pretty smart and knows what hes talking about.

[@gregsarcinello9127]

do i leave glow plugs out while i hand crank engine? and once engine is hand cranked a few times i can go ahead and try to start it correct?

[@troymunsch8244]

So every time you swap an injector you have to dump the fuel and oil sitting in the cylinder?

[@user-dn6qy1ou1f]

You should either do what he did or vacuum it out. Same thing when you change glow plugs

[@psd28]

after replacing them all just take the glow plugs out and crank it over

[@dj3191]

Should the injector cups be replaced?

[@CodytheCarGuy]

Well check and make sure the glow plugs are getting power there is a solenoid by the fuel bowl and make sure you didn't unplug the plug going to the valve cover, these trucks don't like to start if no power to the solenoid no glow plug power = no start

[@adamwaugh5621]

It was a question when the injector goes out does it make it louder noise

[@TheRoshaun25]

Should you grease o rings upon reinstallation?

[@user-dn6qy1ou1f]

A small amount is fine. Or just dip them in diesel

[@timmytool1231]

Great job! I had a boat with a 50 horse diesel, I would send them in to be rebuilt, is there an chance of saving money that way with these injectors.

[@kmxurs]

Where is the oil gonna come out when you turn the engine by hand I mean do you have to leave your drain bouts off or how, cuz you never show when you put the drain bouts back. Just wondering cuz I really didn't get that part after u put the injectors back on.. I wanna do my by my self and this video is gonna help me a lot, just need I little more information in what to do after u install the injector back... thanks I great video

[@rodhart6498]

I have 2000 international 4700 the oil is being pulled from the engine into the fuel tank. Have not been able to find the problem any information will helpful thanks

Injector orings

[@CodytheCarGuy]

well for me its from one to two days, i take it apart and clean them then i put them together and test them

[@73powerstroke56]

Bro I'm doing my valve cover gaskets and internal injector and glow plug harness. But I took apart the passenger side no problem. But there is one electrical cable I can't remember where I took it off from. It's the cable that cones from the main engine harness goes across the valve cover clips into the dip stick plastic hose clamp thingy. Its the only plasitc loop thing that the wire loom gets held in place on the dip stick barket. Well I don't remember where the wire bolts to after that lol. I know it doesn't go to the battery. Where does it bolt to? Pls help. OH and I'm not talking about the wires that go to ur a.c. compressor and solenoid.

[@painter3341]

i have a 7.3 96 and i want to put in some high performance injectors in. should i do the nozzles or would it be too much for the stock injector? or should i put lil swamps on it? the nozzles are cheaper but if it will hurt the stock injectors i won't. if i do any of these will i be blowing heavy black smoke?

[@CodytheCarGuy]

also see how much they will charge you to do the nozzles a lot of times i get injectors in the mail build them and send them back ready to install , you can pm me if you get to that point

[@waynekoehler4662]

Very detailed and clear. Thanks. My first injector repair and I need the education

Ha shooting How to is hard ,trying to show exactly what to look for and stay out of the shot is tuff,and this was hand shot not how id like to do it but cant exactly lock the shots under a hood for everything or a video would take forever. I do a lot of filming and im the live camera guy at a racetrack so different for How to videos.

[@gregsarcinello9127]

could you explain a little more in depth about doing it with the starter; how I go about that? thanks

[@truebengalsfan]

Does injector brand matter

[@painter3341]

asking because its $85 an hour for a mechanic to do it. if it would take him more than 10 hours i probley wouldn't do it then. would it take less time if i just bought lil swamps? or do u think it is really worth it the money? i have already done exhaust, air intake, chip, and gauges and i will do an ats turbine housing and torque converter next.

[@drawkcaBemaNresU]

do you take the fluid out of all the cylinders or just the one you changed the injector on?

[@ronnellbankssr3778]

never worked on diesel but I just purchased a E450 shuttle bus. Wondering if it the same, I need new injectors sleeves

[@Heaugerkerkerk1]

1999-2002 and some 2003s are the same.

[@h82lose36]

When you turned it over by hand did you have the glow plugs out? And I didnt see the torque specs for the injector bolts...Thanks

[@powerstroke420]

Im having problems with my 2001 maybe you can help. it is an intermittent problem i first noticed when i went to start my truck i turned the key over to start engine light stayed on and it cranked but would not start. then the next day i was driving up to a stoplight on the brakes and the engine shut off both times i cycled the key and the light was off and it started right up. pulled codes found an icp code. cleared all codes and they stayed away until i was driving on the highway normal acceleration cruising at 60 when it starts knocking cel comes on and it loses power but stays running i pull over shut it off turn the key no cel starts right up light comes on i drive for about 2 mins goes away and runs like normal all the way home. the last time i checked the codes we found an idm malfunction code and then found a cylinder 7 high to low side open. it sounds fine and starts fine now blows a little white smoke on cold starts but i have not driven it since i was going to do a new set of injectors glow plugs and harness do you think that will cure it? going to do more testing first.

[@Scottypowpow]

I'd even say that would be your cps (cam position sensor) or your icp sensor and even possibly that valve that's like under the fuel bowl I forget what's it called but it was the last thing that was wrong with my truck it made it shut off once the engine warmed up

My opinion is it's a turbo seal gone out. And it's probably dumping the oil into the intercooler

i think and I say I think this will work even though I haven't tried it get a 16 dollar oil 1 pint oil sucker hand pump and stick the hose down into the cylinder bay and suck the oil and diesel out just a idea never tried it. I'm new to diesels

[@Tatation1971]

Thank you very much your video was very helpful

[@jasonradcliff5740]

I had the plug work loose from inside the cover and the way i could tell which bank was not hitting on the cylinder was to take a spray bottle of water and mist the exhaust manifold each individually. if it steamed off right away then you know that cylinder was firing. this saves time and effort if it is the drivers side not firing you would have to pull turbo pipes off.

If this is how you change 7.3 fuel injectors, holy fuck the labor cost is highway robbery. People have to eat I suppose but just wondering because I have a 97model 7.3 turbo diesel. When changing oil do you change top end oil first or bottom end? I want to keep my injectors clean.

What about the fuel in the fuel rail, where did it go and will it hydrolock the engine?

Not if you rotate it by hand or you can take out the allen bolt at the back of the head.

My 7.3 is hesitating when at high speeds like 70mph. I feel like for a split second it jerks. Is this an injector issue?? Also happens when flooring the pedel. High rpm. It happens at lower speeds too. But its constant at high speeds?

[@noontimewhale]

Sounds like CPS

[@timlothamer974]

love your video big help thank you

[@SquillyMon]

Wait...you are RUNNING your engine with the cover removed and then unplugging injectors? That sounds like an unreal mess. Can this be done without a raincoat?

[@dsruddell]

engines can run with the valve covers removed at idle/low rpm without much mess, depending on the style of oiling system. the 7.3 injectors have oil port shrouds for this very reason. it helps on diagnosis. the cleanest way of adjusting valves on a old engine is cutting a window out of a set of old valve covers. it just happens the 7.3l head is so deep most of the oil falls back right into the drain holes.

Also when removing the oil and fuel through the glow plug ports do you need to remove all 8 glow plugs to remove the fuel and oil or just remove the glow plugs from the injectors you are replacing?
