I just saw a short where he started a big diesel truck in -3° weather and he specifically said "no glow plugs" so I came here to find out what the heck that was! You're super succinct and I really appreciate the info!
I’ve mainly worked with Gas Engines, but since I’ll be going to the military which uses a lot of diesels, I would love to learn all I can about diesel engines.
Fantastic! I am the person who knew nothing about it so I very much appreciate the explanation and the demonstration. I must subscribe to your channel coz this type of quality teaching is the best!!
Nice glow plug demo ! I've an '82 300TD..Always wanted to know what the plug actually looks like when activated.. Also, for your viewers: If you drive a diesel too, once engine is warm and you say, go shopping for an hour, say. When you go to restart the car do not wait for glow plug panel light to go on and off. Just turn the key immediately. Otherwise you're just wearing out the glow plug life sooner..IE. They are not needed once engine is warm..But, say, 4 hrs has past, THEN, yes, re-employ the glow plugs...
Great video. You're very good at this - taking the time to even make us complete novices understand. We have a Toyota Hilux/Vigo 2.5D, but really all I know about it is that it has a steering wheel, some pedals, and needs diesel to run... so yeah, on that level... Thanks!
Cheers from Saudi Arabia, Best crystal clear explanation about glow plug vs spark plug. Thanks for your effort and time. I really don't know why the heck some ministries of education miss these TH-camrs, they should hire them and double salary them instead of some arrogant and ignorant teachers ! My youngest brother is a diesel mechanic, he's gonna love this video :)
thank you..i had problems with starting in the mornings.checked glow plugs like in the video..one was taking too long to glow.changed all 4 and problem solved..thank you.
i loved the vid. i learned so much today on how they both operate. thank u soo much. i appreciate the time u invested in to showing and making this video. much respect. God bless..
Good job, when i was a kid even my auto teacher didnt know the difference, now that i have 20 plus years in the diesel field, i still have people coming up to me thinking glow plugs are for ignition
Awesome thanks man! Starting my automotive engineering apprenticeship and these videos are awesome for us people that don't know every little thing about motors haha thanks again man!
Your explanation was easy to understand. Greatly appreciated!

A glow plug in the small hobby R/C world, such as a Traxxis T-Maxx, will sort of look like a spark plug (not a stick) and will have a wire coil that runs inside that looks like a spring. And is way smaller in size like a little bigger than a lego head piece... Most of my starting issues for the T-Maxx were not glow plug related, but was just a complete mystery. Maybe clogged up carb. Most likely ya... I have learned tons more about smaller motors when working in landscaping than I ever have about hobby help docs to troubleshoot your T-Maxx that fails to start.
Thanks for the video , I have a question my tractor is a 3 cylinder diesel and after about an hour it will shut down ,what clue can you give me for that reason? Thanks!
I live in Australia and have a diesel BMW X5 e70. On the coldest days in winter it will get to 10 degrees Celsius. My question is are the glow plugs needed in my case?
Very good video thanks for all the information about the glow plugs. I just have a question about it. how do i test the glow plugs I don't want to replace em all if I don't have to it's a ford 6.0 2006 if you can help me out i will appreciate it
Good stuff, I have a toyota caldina wagon 2200cc diesel engine, so if i'm changing the glow plugs do i just buy any or there are specif ones that I should get? So ive never changed any of the plugs ever. I'm having trouble starting the engine.
Good work, keep it up. I have a problem with one of the glow plugs, there is a leak from between the treads, is there a way to solve this? Thanks again for the well explained video.
Some aircraft jet engines use glow plugs in whats called hot surface ignition however most use spark, In a jet engine the spark plug is much bigger in size and produces a much hotter arc, Jet fuel is a fuel oil that is a cousin to number 1 household kerosene and is not easily ignited without it being heated, compressed or atomized first
hey man that was a really clear way of explaining it, I'm confident with petrol but never worked or needed to learn a diesel, how about a video of explaining why a diesel engine has that distinct rattle noise over an equal sized petrol engine would be good to learn
Hello, Please help me! Why does the warning exclamation light comes on in my Focus MK2 1.6TDCI and this triggers a limp mode? will changing the Glowplugs eliminate this?
Very useful - thank you. May I ask - is it possible for a faulty glow plug to trigger the service light (Car/Spanner icon) after starting from cold and driving only a mile, but then be OK after stopping and re-starting the car immediately? The Garage diagnostics shows nothing, but I did a "pedal check" and got a flashing sequence of 6342 on the engine warning light (engine icon) which, according to various vauxhall/opel forums translates to fault as "H02S Heater Control Circuit Low (Bank 2 Sensor 3)" & also quotes P0683-04 "Glow-Plug Circuit Open". My car is a 2007 Corsa 1.3 CDTI with 48000 miles on the clock. The car drives fine and shows no physical driving problems at all; it has just had a 48000 mile service. I'd be very grateful for your expertise and advice - thank you.
My Fiat Linea 1.3 litre diesel car has 4 glow plugs and 2 are not working. My city lowest temperature falls to 12°C. Is it mandatory to replace the 2 with new ones? My car is 7 years old.
thank you for the informative demo. can we do the same testing experiment at home by placing the glow plug between bricks and the trying to connect the positive of a battery through a wire, holding the wire with a plier? will this be safe?
Bigger trackers i work on dont have glow plugs or grids. Some might have either start but no one replaces the either cans. Most in cold weather areas have block heaters to plug in 120 volt to keep the coolant system warm.
question have a 2011 duramax was about 30 degrees yesterday morning. Went out to start my truck has been running great and my check engine light was on truck was running fine. Went to auto parts store they did diagnostic and said it was the glow plug for cylinder #7. I replaced the glow plug for #7 was fairly easy cuz was on my passenger side and I'm sure it was the right one passenger side closest to Cab. Even after all that my check engine light is still on do I have to clear the code to get rid of it or is something else wrong thought the light would go away after changing the problem glow plug.. any help would be greatly appreciated.
Glow plug questions! 1) I've heard it said that if you try to start an engine before the glow plug light turns off you could damage a plug. Why? 2) If you have (already) started an engine while the glow plug light was not off is there any correct procedure to move forward to lessen any damage? Thank you for this informative video.
When I lived in Germany in the 70's a friend had a Mercedes 190 diesel. I remember in the winter time he had to go out and turn on the glow plug and wait several mins before he could start the car. I always thought that was extremely inconvenient.
hi sir i just wanna know whats the problem if the car cranks and hard to turn on, ive got a deisel car it wasnt like that before i normally starts it by just turning the start but now i need to accelerate it before it starts😕 please help i would gladly appreciate it thank you
So I've been put into a diesel truck at work, and it has a knob with a symbol looking like a choke on it. Is that related to the glow plugs or something else?
+dieselworld: will this glow plug lit every time we turn on the key? u said it helps in cold start. say my engine has already run few miles and its hot. Now i turn off the engine and start it again. will the glow plug lit in this case?
+Deepak Naik In normal cases it only turns on when when the coolant is below a certain value. For Volkswagen its around 18 degrees or max. 5 minutes glowing time when they will turn off.
Thank you for simplifying it! Question, what is the "life-expectancy" of glow plugs on a vehicle? I know for hondas the tune interval is 105K miles.. do glow plugs last the same? Thank you for your time.
what does it mean if the glow plug warning light turns on while the car is turned on ? it happened several times with me while driving and i had to stop and restart the car
This is very very very helpful for me! Thanks mister! by the way, we just changed the glow plug in our diesel engine car.. but sometimes the engine wont start normally. can you answer me what might be the cause? is it on the battery? or maybe there are wires that are connected from the battery to the engine?(broken wiring i think?)
Do the glow plug activate when you turn the key full way as to start the engine, or does it start when you turn on the ignition (like, turning the key half way? Get the displays and radio on). In cold climate (say around 0 and less Celsius), would it be beneficial to then keep the key half way on for a while to let the glow plug work and heat up the (intake) air to help the engine fire? Or is it that the glow plug start first when you make a full turn of the key to get the engine to rotate and start?
something for a rule of thumb i have found, anyone with experience building engines (and actually knows what they're talking about) you have two arrows. one up and one down and two factors, compression resistence and compression ratio. petrol needs up resistance down ratio, diesel is inverse. just by factor on how they work, diesels need more compression ratio petrol's do not.
no it won't, If it's black smoke it's just unburn fuel, if that is the case I would check out the injectors and the injector nozzles as well worn nozzle would cause more of a wider/ bigger spray aka more fuel than normal- more un burn fuel- black smoke out of the exhaust. if it's ticking it's probably the injectors
I figured out what glow plugs were long ago, when I was learning about gasoline engines, and what causes detonation/knock/preignition, and how to prevent that. An air/fuel mixture exploding from just being squeezed, that should never happen in a gasoline engine. An air/fuel mix igniting, not because of the spark plugs & their timing, may damage the gasoline engine. Detonation/knock & preignition, may not only happen, because the octane rating of the gasoline, is too low, but also if it's a very hot day, and there is something wrong with the cooling system. So I figured, since Diesel engines rely on the compression strokes, to create enough heat to ignite the diesel fuel. Glow plugs, must be things that heat up the engine, when it's too cold for that to work...and I was right. And the word GLOW, was also a big clue. It reminded me of the heating elements in a toaster oven. This is a very good video. Thank you for showing a glow plug.
I went to an automotive school, but I don't remember that much about Diesel engines, because they were briefly mentioned, and when learning about the 4 stroke cycle, we focused on gasoline engines. But what I did hear about Diesel engines freaks me out. Diesel engines have much higher compression ratios then cars, they don't use spark plugs, they control when the diesel ignites, by squirting it into the cylinders, at an EVEN GREATER pressure. This is why the fuel lines for Diesel engines, are made of thicker metal, then gasoline engines. The diesel fuel is at such great pressure, that if there was a pinhole leak in the fuel lines, and you waved your hand over it, the diesel will cut into your hand, and diesel in your blood will kill you. This is why Diesel engines creep me out. Especially if they were in a crash, and are still running.
I've been running my gasoline generator on kerosene like really pure k1 kerosene And when I turn the engine switch off (the spark plug should stop making sparks) the engine stays on just because of the compression lmao I have to choke it and turn off the fuel line and It seems like no damage
@@Tsifdgoyddo I was talking about working on a Diesel engine, after a crash, or diagnosing it while it's running. I'm worried about a hole in the fuel lines, because of that, or sabotage. But I'm loyal to EVs now, and building Electric motorcycles now. But Diesels still creep me out, for those reasons
The "have a safe day" got me. Anyone can have a good day, but not many are safe through out it. Good shit
A trick : you can watch movies on Flixzone. I've been using it for watching lots of of movies these days.
@Ahmed Ryan Yea, have been using Flixzone} for months myself :)

In Saudi Arabia, does it ever get cold enough that a diesel engine needs glowplugs to start?
@@bartholomausallen883
yeah, we have sub zero zones, and it snows up north.
You confirmed my understanding of the difference. Thanks for a simple explanation and demonstration.
Explanation with demonstration is the right equation!! Excellent video. Thumbs way up!
Finally a TH-cam video that I can respect. Good job!
Dear Sir,
Thank you very much for taking the time to produce such an informative video. It was very educational.
thank you..i had problems with starting in the mornings.checked glow plugs like in the video..one was taking too long to glow.changed all 4 and problem solved..thank you.
Thanks that was a spot on lesson. Just about to buy a diesel with a glow plug fault which I fear no more. Cheers.
You are a great teacher, just got my first diesel, thanks
Thank you. So we should wait for the "coil" light to go off before starting a diesel engine?
Yes I would.

. Can you please make a video about the differences between the Gasoline & Diesel engine . Thanks in advance
Hey thanks for the video! I have a question, what's really the difference between a "cheap" glowplug and an expensive one?
Everyone likes the excellent explanations but none subscribed? Not fair
wats the battery ur usin? thanks a ton in advance!!

You showed the glow plugs working, but could have maybe added spark plugs being tested in HT leads too for people to know how to test bad plugs.
That was excellent. Now, do you do one for the glow plug switch? I have a 1996 GMC Suburban Diesel and it may be out, or I have faulty glow plugs.
Wow I never even knew that these existed. I thought that all engines apart from Jet Engines used Spark plugs. The more you know! Thanks for this!

You're a good Guy!!!
what does it mean if the glow plug warning light turns on while the car is turned on ? it happened several times with me while driving and i had to stop and restart the car
Probably just a sensor. If the car was up to operation temperature then it was just a sensor gone bad.
what's the typical resistance of a glow plug?
Nicely explained the glow plug & spark plug, thanks.
How do you tune up a diesel engine?
Can you do a video on a basic glow plug circuit? my glow plugs seems to be ok but the glow indicator in the dash still lights up constantly
how much dc voltage and current is required to start both of these plug

hello sir i have a mahindra jeep, glow plug indicator does not show every time on indicator
Do the glow plug activate when you turn the key full way as to start the engine, or does it start when you turn on the ignition (like, turning the key half way? Get the displays and radio on).
In cold climate (say around 0 and less Celsius), would it be beneficial to then keep the key half way on for a while to let the glow plug work and heat up the (intake) air to help the engine fire?
Or is it that the glow plug start first when you make a full turn of the key to get the engine to rotate and start?
Nice video man cheers. Never seen that before. 👍🏻
Good video, thank you for explaining it so well, and displaying the function! MUST WATCH VIDEO
Very well explained, thanks dieselworld!
something for a rule of thumb i have found, anyone with experience building engines (and actually knows what they're talking about) you have two arrows. one up and one down and two factors, compression resistence and compression ratio. petrol needs up resistance down ratio, diesel is inverse. just by factor on how they work, diesels need more compression ratio petrol's do not.
Thank you for the knowledge 🙏
I knew about compression ignition in diesels but never understood glow plugs. I do now. Thanks!
how long do they last before replacement the glow plug.
Several years for sure.
Very simple and useful. Thank you!
Thanks for posting. That was very informative.
that was a fantastic amazing video search keep up the good work
Thanks!
thanks I learnt something new ....
Great!
Very enlightening video. Thanks.
Can i ask you Once ? If the Glow plug of my Diesel Engine Not work well the Engine will make a lot of smoke and sound ?
no it won't, If it's black smoke it's just unburn fuel, if that is the case I would check out the injectors and the injector nozzles as well worn nozzle would cause more of a wider/ bigger spray aka more fuel than normal- more un burn fuel- black smoke out of the exhaust.
if it's ticking it's probably the injectors
That's incredible. Thank you
