7.3 PowerStroke -19ºF Cold Start Attempt
Вставка

- -19 F cold start attempt without the block heater on a 2000 7.3. Arrived at the hotel late, and could not get a cord from maintenance to plug it in. After many minutes of trying, we got a cord and plugged it in while we were at the dirt bike ice race throughout the day. Batteries or starter never died, which was impressive.
That starter just went though about a years worth of starts.
Robert Brunner starters are cheap
HERPY DERPEDY um they are not.
Fizzi about 120 bucks a pop. My shitty car quest starter starts fast and has been through so much hard start abuse lol
Keep in mind it’s also very cold out
@@bryanmartinez6600 shouldve had the heater in, in the first place🤦🏻♂️
Daaaaam man. They must be giving starters away nowadays. Im genuinely impressed it lasted through that situation
So cold it probably stayed relatively cool
I want to know what batteries were in that thing?
No kidding!!!
Don't we all and have mercy that is a tough starter as well
Probably a DieHard...
I was thinking the same thing lol
Right?????!!! I was thinking this after the first minute of the video. Holy shit.
All I got to say is that those batteries definitely lasted longer than mine ever could 😅
to all the people saying hes over cranking the starter, just want to point out all the cuts in the video and the fact it was -19F. the starter will have time to cool down. most of the stress was on the battery and engine (starting rpm is usually too low to pump oil for lubrication)
when its that cold, its always a good idea to plug in the block heater, also make sure all your glow plugs are working.
He's got a loss of compression on at least one cylinder, meaning the engine's done regardless. You can hear tell by how the starter speeds up then slows down again. Means that piston ring's dead, also explains all the black smoke. Low temps or not, the engine's cooked. Sadly, very common with these. So really, the low temps had very little to do with why this truck didn't start.
+Vercus100 Was thinking the same thing.
Could also just be a only a couple good glow plugs
Haha yeah that thing is toast. I'm sure the rings in that cylinder have been through the shredder and the connecting rods, bearings and pistons are burnt to hell. Also would put money on it that the oil in the top end is thick as mud and he injectors are sickly and probably the glow plugs don't have correct ohm reading.
+Vercus100 isnt common if you keep on top of the maintenance properly.
It could be that 1 cylinder has a better glow plug then the rest. So one will fire and the rest will not
all I can think of is this is like every horror movie I've ever saw where the killer is trying to get them and they are feverishly trying to start the car. just needed a shot of the driver frantically pumping the shit out of the gas pedal. LOL!
what kind of battery is in that son of a bitch
+Carolina Crustang. (Carolina Crustang) 7.3 uses 2 batteries
+VK70001.P jut the same it cranks a good long time.
+Dan Carlin yea but good batteries should have close to 1500 amp hrs
+VK70001.P 1500? Thats a lot of amp hours. Good batteries should have 1500 cranking amps though.
+Citroable that's what i meant it was a brain fart moment ha ha ha ha
With THAT MUCH cranking, the cylinder temps (on a healthy engine) would have been well in to the temperature that is needed to ignite diesel.. With no preheat system, and good compression.. it should have started after that much cranking. Furthermore the flame front of the ether should have fired the diesel injection off no problem..
This engine has way bigger problems than this video lets you believe. I would bet (that before the generous application of Ether) that this thing is deathly low on compression..
8v-of-fury agreed
Frozen fuel
its because of the high pressure oil pump injection setup if the oil is thick and cold it cant trip the sensor and open the injectors
when dose a 7.3 not have issues.
My obs 7.3l has treated me alright in the cold, 0 out unplugged with glow plugs for 20-30 seconds and she fires right off. I do of course make sure to give it some anti gel just to be sure but yeah. Let it idle for a minute to get the oil circulating then hit up that fast idle for a few and take off down my hill at a generous rpm.
That´s some impressive battery and starter capacity.
Diesel has two batteries. So he's using one battery.
Nolan Alvarino No, these trucks have two batteries because the starter has be large enough to compress to the air to twice that of a gasoline engine.
Aluminum, the 2 batteries are wired in parallel, meaning they both work together at 12 volts nominal.
And your glow plugs ?
Are they working here ?
Next time if you want to start it quicker use a hair dryer in the airbox : )
michaelovitch or just spray break cleaner to help start it. Works 5 times better and does no harm to the motor
Matt Law Brake cleaner is a form of degreaser that seems like a bad idea to spray inside an engine that you want lubricated
@@DerrikNikkelStudios well gasoline degreasers too, so I don't see the problem
Glow plugs wouldn't help this engine. That truck obviously has low compression
@@budphillips9301
obviously,i don't know,at least they seem all equal in compression,there is no miss or irregularities while cranking.
i've never had a problem with my 7.3 with 350k miles ... turn it on in the winter and let it run till spring .. what's the big fuss about ?
Your glow plugs are beyond shot!
this is why i got rid of my 7.3, i worked out in wyoming and north dakota alot and it didn't like starting at temps under 20 degrees. anything in the negatives and the truck just wouldn't start. my 05 5.9 cummins starts in -30 weather after sitting for a couple weeks.
tech tip: use a block heater
and spend a shit ton on electricity
@@mikeroberge8928 As opposed to the cost-free wear and tear on your engine. Ok
Do you see where he is?
Read the description
Damn, what kind of batteries were in that thing?
Get a cord from maintenance? What- no room in that truck to store one?
Sorry, but you're wrong. At work, we have 10 Ford 7.3 1 tons, and 2, 6.7 Dodge 1 tons. We plug the block heaters in along our building, but, someone forgot to turn on the panel. -30 celcius, and the only 2 that fired up were the Dodges. All the Fords sounded exactly like this one....only our batteries didn't last as long as those! (Hot damn, those are good batt's!) I own a Dodge 6.7, and plugged it in once this winter, and over half the winter, it was -20 C and below. Fired like a champ!!
They all need new glow plugs then
Funny thing is my 7.3 would fire right up in -20 weather
Probably because you're not an idiot and the guy that owned this one was
That's why they have block heaters my friend
@@wyatttipton9957 Its funny that most people don't realize the 7.3 has oil fired injectors... If the engine oil is gelled up solid, no way in hell is it going to open the injectors. lol ( KATT magnetic oil pan heater, is a 7.3 owners best friend )
If you're injectors are good a 7.3 will start on a dime every time without glow plugs.
5w40 synthetic helps too
This lady's and gentlemen is why they invented block, oil, and air heaters for engines. So you don't trash your starting system. Also wouldn't surprise me if the fuel started to gel. Because at -10 is when diesel begins to wax (correct me if I'm wrong on my temps). Your hard on your fuel pumps and starting systems. If your 0*F and below use your heaters and plug it in.
I have a great idea! Why not get some new glow plugs, a glow plug relay and don't forget to plug in the truck during sub-zero temps! Then you wont burn out your starter trying to start this beast. Its painful watching people treat these trucks like this!
Very impressed with the batteries I wish I knew what brand they were
This was a little painfull to watch. But holy shit those batteries are insane :D
its trying so hard to start. i feel you man, i feel you
Somehow I get the feeling he'll be plugging that in from now on... If you was really in a pinch you could build a little fire under the engine, you know put a few hot coals under there, then block the wind with cardboard or something. Had a car one time that was hard to start, of coarse it was gasoline so it's problems differed. The old plugs fouled out under a new oil change, and the battery wasn't all that good, it was -25F out. Ended up changing the plugs and setting hot wood coals under it to warm the engine while charging the battery. A few hours later and it cranked right up.
My 97’ powestroke starts almost right away in the winters in Minnesota and most nights I don’t plug it in it can get to -30 where I live
Never heard a 7.3L sound like this. Never seen the dark smoke like that either, I always get white smoke. I think this start was indeed harder than mine, lol :) Judging by the pop backs I heard and the massive amounts of fuel she was injecting, I'd have to say the IPR was hanging closed. But I don't know, only way to know would have been to hook it up and look at what the PCM was commanding.
that is one good starter and even better batteries
Geez, the battery nor the starter died after all the cracking!!!!
I have a 7.3 as well. It starts great. New batteries and alternator helped, but there is a little yellow valve that drains the water behind the engine cover. You need to drain the water out at every oil change at least, if not more often. You will be surprised how much water that 38 gallon tank can collect!
I want to know what kind of batteries this thing has. It is really impressive!
Every diesel owner should watch this video. Too bad you guys couldn't get it plugged in earlier. I feel bad for the main bearings, but I'm sure that the engine was fine.
It was like watching a diesel locomotive starting up...
Is it the injectors or the engine itself making the chattering type sound. I notice this on all cold starts just wondering. Don't sound good but if they all do it.
That's one good battery
Goofygiggles must be an Optima but remember they have dual batteries
Correction: those are two good batteries
takes 2 BIG batteries to crank 7.3--I have replaced several in 10 years I have mine
My 04.5 (common rail truck) started at -25 not plugged in. The noises it made almost made me wish it didn't, but it started and ran.
that engine will be gone soon if you keep spraying ether in it
Yeah I cringe every time I see people doing that shit.
Kody Kill put a gas soaked rag over your air cleaner, and, plug it in for sure!
Barry The Chopper I Feel the same way!! :/
I guess they like the after market melted piston style
Kody Kill Not mixing with the glow plugs so there’s a very low chance of preignition before the cylinder. Plus I’m pretty sure that’s what made it act like this to begin with.
You are sooooo Right. Damn. Anyway, I have a 2000 F250, and It wont start any body have any assitance to lend. I drove it downtown tonight, and it is about 39 degrees, about 2 hours later I tried to crank it up to head home, and it wont turn over. The lights and radio work, eventually after a couple tries the windshield wipers came on and the radio would come by themselves. Any Ideas anybody.
maybe you have bad muffler bearings?
+Illyrian4life LOL, bad glow plugs in his batteries.
+Patrick TheBaptist well i would just beat on the starter with a left handed hammer. lol
Illyrian4life
Hahaha. I've felt like doing that and hitting myself in the head with it while I was at it... LOL.
+Patrick TheBaptist lol
cmon guys he needs to change his spark plugs get it right lol
holy shit dude.......where can I get one of those starters???
should have saved the wear and tear on the truck and plugged it in
did you even try to take a screw driver and jump the glow plug relay? i bet the relay just took a crap so the glow plugs werent even running.
man plug the truck in.
I’ve fought many winter wars with the 7.3s and there is nothing that sounds angrier than a powerstroke cold started at -10 or less. That’s what block heaters are for boys, plug them poor dinosaurs in 👍
in minus weather give the plugs about 20 to 30 seconds to get hot enough to ignite the fuel.
+Jim Trotter done before on my diesel mower that glow plug helps alot
I have a Minnkotta dual head battery maintainer mounted on mine. It's plugged in before the block heater and works great
Maybe keep it on the block heater at night when it is that cold?. Just sayin.
I just want to know what batteries you have so I can buy a set 😂
This engine has seen much better days. Cold start or not, I think the motor is done.
+mustang10141980 It's not done at all. Mine has 350k miles on it, 94 and it's been starting like that in the cold for years. Still runs fine. We hardly ever get below 30F so I don't see issues with starting.
Y10Q oh for sure. I know the body will rot around the engine on mine. Navistar made a damn good engine when they built the 7.3
I've noticed that the 7.3s have a really hard time staring up in the winter unplugged over night its really a hassle
I wouldn't mind having that battery.
Amen. Starting fluid (either) dries out upper cylinder lubricant and causes knocking that can result in seizure eventually through the use of way too much. I know its diesel but that knocking is intense.
dam good starter
Maybe you have to replace the spark plugs or the blinker fluid. I would recommend 72W-139 full synthetic.
Nick Darlington ur honestly stupid diesels have glow plugs and are internal combustion engines
Matt Law It was a fucking joke, dipshit.
Nick Darlington stupid dumb meme go fuck yourself 🖕🏼😂🖕🏼
When you think its a compilation buts its just a single truck "starting"
Didn't see the last part when I said that, but seriously, 5 minutes of cranking?
poor starter took 1 for the team on that one. lol
Could have pushed it back into direct sunlight. With the bonnet open surely an hour of direct rays would make it easier?
Daniel Molineux thats not a bonnet. this is america its a hood
chase gibbins but you know what I meant so who gives a fuck? This isn't America, this is the internet full of different people with different ideas and different words.
chase gibbins English = Fag? You speak out language bro, it's OURS. You borrowed it and made some changes. Either way, it's a flat piece of metal that covers your engine and other parts. It doesn't matter if you call it a Hood, a Bonnet or a Flundingus, i is what it is.
everybody hatin on old powerstrokes better than a chevy or a dodge
+Travis Vandling, You're going to worship this pile of shit even after having the video evidence above? Go pick up a stock 6.0 and leave it stock, report back 1 year! lol
Whatever pussy dodge gm driver
My dodge Cummins would have been running by now alway starts good
No thank you. Had a Pontiac g6, and always started cold on the first try that was even colder then this.
you wish
Cycle the glow plugs 2 or 3 times before trying to start, started my 97 7.3 that way several times at -5 deg...started right up...
guess the glow plugs or the glow central are defect on this one...
yup i have to do the same thing with my 97, glow plugs finally went bad at 231k
If all the glow plugs systems are working they will start down to 0 deg farenheit been there done that....
5:45. Should of done that the first time it wouldn't turn over not after the 428th try.
Haha so funny! 428 times later. I am rolling laughing!
"Hmmm. Spend over 2 hours trying to crank it then give up and plug it in for 4 hours and screw the Ford or plug it in right away and wait 4 hours. I'll just go with the "smartest" option. OPTION 1!" Well folks say hello to this winter's dumbest Ford owner!
Lmao
when you live in cold climates you have to keep up on your glow plugs replace mine every year (may be a little excessive) and my 7.3 will start all winter with out being plugged in even on those -60 nights
Jay Williams yikes that’s really insane
impressive batteries thats for sure
What kind of batteries? Nuclear plant under the hood?
Wtf the fuel is obviously gelled up there's nothing wrong with the truck
Damn how many starters did you use for this video?
I've never seen a 7.3 start this bad. That was pure garbage...
+Bailey Hill Agreed, there's more than low temps at play here. That engine's completely destroyed. Even when it did run it sounded like marbles in a blender. I'd toss the engine and replace it.
A mechanic told me if your having cold start problems it's because your injectors aren't working properly
I can't stop laughing that 1-2-cah3-1-2-cah3 hahaha
As much as I love 7.3s the right idiot can fuck anything up including a 7.3 and I think that this was the case of this one-time beauty's demise
+Bailey Hill they should have cycled the glow plugs a 2nd time my 97 powerstroke would start cold in -40 but it did take 30 min to warm up enough to drive without gelling
My brothers 7.3 use to do the same thing. If i got colder than 40 (which was everyday after august) his would HAVE to be plugged in hours before you wanted to run it. Just a pain in the ass.
Great truck. Not so great at cold cranking
Cummins never let you down
well proven engines. especially the the 6bt.
How is it starting by itself😊
Fords keep mechanics wealthy!
Not so much as dodge with their loose front ends and bad transmissions what we have here is someone who doesn't know what a plug in block heater is
No they're not my friends duramax is always locking up on him and his truck only has 45,126 miles on it, and I don't like automatics in the first place, the ZF6 is the best transmission I've ever had, 200,000 miles and still going strong
On a big rig the only acceptable transmission is an Eaton fuller 18 speed, had one on my freightliner with a 650 tuned cat C-15 single turbo. Beast mode 24/7
lmao Because a Duramax or Cummins woulda fired right up. N the truck in this vid is a top notch Ford, right?
The 7.3 is Navistar's best engine. A 6.0 can be just as good if the EGR delete is performed as for Cummins and duramax they too should be plugged in in seriously low temperatures to keep them running good and there isn't such a drastic change in temperature between uses
i also seen one do that when it had lost compression check and see if u have fuel in ur antifreeze if so then uve got a blown head gasket
SHould have just plugged it in in the first place!
Read the desc.
That is some serious cranking durability! Not to mention the batteries, how did they last so long??
1 word Lucky
no more either please!
Up here in North Dakota It gets Dow to -20 to -30 and my 2000 7.3 dose just fine
truck was not taken care of. When thy are they will start
You can tell by the noise of the starter there is a compression issue on this engine.
Yep, you can tell because it cranks fast and then slow. That's obviously low compression in a cylinder... Or for this particular truck, low compression in multiple cylinders. This video is pretty old though so I'm sure that truck is in the junkyard by now lol
@@budphillips9301 I heard the skip too. It's probably accruing miles still! Lol!
Did it even have a single glowplug? Lol
John assuming he uses ether every time he starts the thing like he did in the video, ya
Doesn't this hurt the truck if you try this 2 many times?
Why would anybody post something like this for the whole world to see? It's like saying, "hey world, look! I'm a shit for brains!!"
Was he revving it immediately after starting it? Doesn't that enrich the mixture and cool the cylinders in a diesel?
Cold starting for 6.9L through last of 7.3L is to put your foot 1/2 to full throttle. Old mechanicals lay it on the floor or pump it depending on what she likes. Seriously, more fuel generally. Diesels don't work like gas at all.
No matter how much power a diesel makes, this is the reason most people still have gas engines in their vehicles.
+reints74 gas or diesel cold weather makes it hard for an engine to start
Cross Durazo Sure does.
A well maintained diesel starts about as good as a gas job. Usually when you start seeing diesels not starting, it's from lack of maintenance
FCFordLord I believe you're right. I know this truck is in need of serious maintenance & the majority can't be like this, or nobody would own one.
+reints74 true and I kept my diesel ford up to date running better than before a lot better starts in -20 like its 50 'f outside
Not trying to be rude, but was the truck maroon or green before it was wrecked if it was wrecked?
what a powerjoke.
You mean powerchoke
Buuuttttt still beats precummins
mightaymouse doubt that
+Future Gohan Stomps any Duracrap but out doing Cummins is unlikely.
So why don't these engines start from cold?
Diesel does not ignite nearly as well in cold temperatures as it does during warm temperatures. Diesel is effected by temperature far more than regular unleaded gasoline. Gas engines will have trouble starting at -19F too, but not nearly this much.
I am actually a mechanic and have worked on diesels for years and even with glow plugs down most engines will start in the cold after being cracked as much as this pick-up. Just wondering if there is an issue with this Ford 7.3 engine which causes poor starting?
St al fuel gels up cant flow
St al Part of the reason is that diesel are compression ignition, so they compress the air (usually around a 18:1 ratio) causing it to heat up and ignite the fuel when it's injected. So when doing a cold start the heat that is building up in the cylinders is escaping through to the rest of the engine before it begins to maintain an Idle speed.
Deisel engines also like the block to be warm like the other guy said also they have to compress air
I think I just wasted 6 mins if my life....hahahah
i'm with the other guy,what kind of batterys are you buying,i want some,see the black smoke and then it turns white to blue,some of your glow plugs or all of them are seriously lame,be glad it's cold or you would be buying a starter too
it's a Ford what do you expect
+Dylan Aarhus you can't beat a 7.3
Meade Mathis want to bet Cummings is a way to go if your smart
+Dylan Aarhus you mean cummins?
+Alec Glass yeah that's what I meant
Dylan Aarhus i think your both mistaken. What your trying to say is Mercedes-Benz
Wow! Nice cold start But i think that the timing is not good(to much advance) just to hear the dry clagging wow never heard that before ! VeryNice cold start video !
more like powerchoke
Alegabi1 go home
chase gibbins go home
At least im not drunk enough to realize ford sucks Perfect example: This video
Alegabi1 well when a truck is ragged out of course its gonna be a turd. its all in how you take care of your shit.
Yeah no shit.
that's a nice truck what size tires are those? Stock lift right?
Typical ford
Grabs popcorn
We might be here awhile
7 months and still nothing... I'm impressed
mightaymouse Same
Chickenhunter22 hater....they all do this if it's cold enough
Typical Chevy idiot
what batteries are you running lol those things took a beating
Come on baby, pump it pump it, come on come on, pump that pedal, pump it. OMG love the cranking of this truck.
It seems that in the car filled summer diesel fuel, and it began to freeze in the fuel filter. Because the motor easy start with starting fluid and couldn't run on diesel.
Hahaha, Pidgeon, Phil and I still pull this one up and watch it once in a while for a laugh.
Bad glow plugs? I would have probably found someone with a torpedo heater,
are your glowplugs not working
looks like maybe the engine oil was too cold to fire the injectors in the high pressure oil system...?? I would think that after almost starting that many times it would fire off easily.
