Delboy's Greatest Hit #3

[@AdrenoChrome89]

This video makes me feel like removing brake material, smearing copper grease on my pads, labelling my connector blocks and performing a coolant change straight after a 200 mile ride 👍

[@Cnicbr]

We all do

[@nutgone100]

Don’t forget to polish your discs too 🤣

[@patappleton6285]

It's so good to see two fellow youtubers consulting and working together for the good of all.

[@wibblywobblyidiotvision]

17:57 Del's not inquisitive, he's bi-curious. That beard is pure grindr. 49:12 - holy shit. Did he just say that? "It's a fact, it's proven, it's on the website". Oh, and for anyone who doesn't understand why it's fucking dangerous to open your radiator cap when the engine is hot. Firstly, y'know, it's fucking hot, innit, and you're venting hot gas. Secondly, though, the boiling point of your coolant will rise as pressure rises. So as your engine gets warm, the pressure in the system rises, and the boiling point of the fluid goes up, up until the point where the radiator cap pops. At that point, the fluid can be up to 120°C before it boils. Opening your radiator cap at this point will vent the pressure (which is frankly fuck all), but suddenly, all of the fluid finds itself at atmospheric pressure, and its boiling point is back to 100°C - a whole bunch of it may well then *instantly* boil and blow a load of boiling water out directly into your stupid fucking face. Not recommended.

[@sidwainhouse]

I was taught it is known as the Vesuvius effect when the pressure is released, pretty nasty shit when it happens.

[@TornadoCAN99]

Yes. And he never considers the fact that steam gets MUCH hotter than boiling water. That is why steam burns are so much more severe than hot water burns.

[@millsey123]

I honestly think he believes the whole cooling system turns to steam once it reaches 100 degrees. Its amazing and shocking at the same time 🤣

[@TurboRichie]

When the cap pops and let’s it “overflow” it releases some pressure. As the coolant in the rad cools it will create a vacuum and suck the perfect amount back into rad…

[@Marky948]

Every time this video makes an appearance on my suggested vid list I have to watch it if not only for the quality of the thumbnail. 👏

[@Dozeyish]

Wow I did not realise this wsnker was actually so popular. Years ago I watched one of his vids on servicing a sportster. Most of it was wrong and I thought then this shouldn't be allowed. How he got so popular is amazing. Thank you showing him up for what he really is.

[@paulperry8800]

Oh, I've obviously been lied to for all these years. Now that Del Boy has explained it, I'll tell my former tutors, that the temperature differential between two liquids is irrelevant in cooling systems. Cheers Del! Utter Pillock.

[@randersson3672]

Some people think Matt is "mean" for making these videos, HE IS NOT. Del is just not someone you want to learn from, period...FAR FROM IT ! "It's slippery" 😆🤣 !!!!

[@H-M-78]

It is not nice to talking sh-t and lie like Del either. And remember, -we can take that channel down in a moment!

[@meshacht4978]

Never mind put him on national TV to encourage people to watch the shite... lolo

[@Unfunny_Username_389]

13:40 - lol at that wire basket faring - that's why I dubbed it the Deep-fat Fryerbusa

[@theoldman8877]

In support of your position on hot coolant. A local ambulance company lost 5 ambulances by running 100% antifreeze instead of the proper 50/50 mix. Those vehicles burned because antifreeze is flammable if not mixed with the proper amount of water. All that was needed to get the fire started was a very small cooling system leak. Your advice about living the cap off or lose is good.

[@archiedentone5950]

It burns @50/50 given enough heat. This is how the Tesla grid batteries catch fire like the one in Australia did

[@buzzardbeurling]

I remember when this came out. I Genuinely had to watch from behind my hands. Shocking!

[@julianpiper240]

7:08 terminology for those interested: draw-through is known as induced draught (draft?) and blow through / push through is forced draught (draft?)

[@combatclifton]

If I had 3 cycles on my KTM fan I’m sure it would just overheat and throw it’s coolant on the floor 😂

[@Mr.MusicJunkie]

Good engineering from KTM I guess. Less coolant to drain, saves time 😆

[@bearcatracing007]

We where warned when doing pre-delivery, only idle for under 2 minutes. Basically let the customer blow it up lol

[@KrikkitWarlord]

Isn't that the way in the manual to make it quicker to change? :D

[@mazdamaniac4643]

Del's a classic example of "The most dangerous type of person is someone who _thinks_ they know what they're doing." If you don't know what you're doing, find out how beforehand. Use your brain. Read instructions. Get advice from someone who does know. *Do not be a Del.*

[@melclark1066]

Del is a genius: I have never before seen anyone who can talk (almost) non stop for so long, and with such confidence, yet manage to, not only get everything wrong, but potentially cause damage to both person and property at the same time. He gives new meaning to the word Imbecile.

[@meshacht4978]

You make my fkn day you do.. !!! I smashed my shoulder and 6 of my ribs the other day in the wet like a fool .... So over the last few weeks I have been re- watching all of the really old Delboy stuff and your responses. Where it al came from, trying to get your channel taken down and all sorts .. lolo. So. I just fried some chicken and chips. I will now sit and enjoy this instalment of Del at his best.. Keep up the good work mukka !!!

[@homeviewing8700]

Matt will probably correct me but i never take the water out of a hot engine and years ago that's how we we trained , apart from the obvious of burning yourself it can lead to engine and gasket etc damage. example, if you just turn the engine off on a water cooled engine and then remove the water from the system the heat that still exists within the engine which is much higher than the water temperature has no medium to flow into (ie water) ...the water after you turn off the engine can still transfer the heat away from the cylinders etc... on an air cooled engine and you turn it off the heat dissipates in the normal fashion through the fins

[@faultygoods9985]

Del is a national treasure. I watched the video where he added 2 extra indicators to his busa. Its fucking gold. I for one will be giving all his videos a thumbs up and joining in with the mentally ill people that leave comments on his videos so he never stops making them.

[@glenstack6512]

found Matt from Craig Jones that led me to Dell. If I had seen Dell first I would have thought every one in Briton was an idiot.

[@JohnCacic]

he's explanation of how a gearbox's gears mesh is one i can never forget .

[@midenking9651]

7R is an expansion chamber and they actually expand quite a lot so he's just F*cked the cooling system doing that 🤣 However my TR Race Spares Cap doesn't come with the warning on the cap.

[@H1GhW1Re]

I reckon Del drunk a bottle of Evans and then thought I know I need to do a coolant change whilst its well over 100 degrees as it's not dangerous at all. In Dell's mind That warning shit the manufacturers put on the cap is just nonsense. I can do science me !! Epic!

[@JAMESWUERTELE]

Taking the expansion tank off, is a crime against Kawasaki.

[@icklepob88]

Will he only stop giving extremely dangerous advice when he ends up with someone taking him to court for their injuries ?

[@michaelgreen4585]

Brilliant Del is the uncrowned king of bull

[@chorleycake7942]

Apparently the new zx10r now comes with an old HP sauce bottle instead of an expansion tank saving kawasaki millions of Yen per year. If I was going to buy a second hand bike and it had an evans sticker on it I would keep walking.

[@UnCivilEngineerIRL]

Del: steam doesn't cool anything ! You listening Matt ? Don't sweat it !

[@jmrracing7097]

I love these

[@davidk1644]

Your face at 9:51 when you remember " he's going to do it again". Absolutely priceless.

[@danielroe845]

I wish I'd have done a video of us draining the Evans out of my engine. That shit is lethal. If you've got anything with an internal oil cooler or prone to head gasket failure or gallery splitting issues then steer well clear. When it amalgamates with oil it's nearly impossible remove from the system. Evans know this, they know exactly what it'll do and will send you no end of free shit to stop you kicking up a stink. Also, I can only assume Del is so fucking dense that he confused draining warm oil with cold coolant. What a man

[@Al37100]

So towards the end of the video he talks about EXPANSION bottles and header tanks but at the start he talked shite about it being an over flow bottle. It was the busa coolant vid that finally convinced me just how dangerous he can be. And if you watch him closely enough there are many times in the video where he knows he is talking shite but just carries on.

[@Maddmank]

You drop these vids in perfect timing for my nights off 😂

[@NotRodder]

That non identified front end thingy/fork seal issue you mentioned, it's just electrical wires, probably the front indicator wires hanging down waiting to be finished to length

[@dirtygarageguy]

No, it's the wire out of the reinforced rubber pipe he covered the shocks with

[@weaselman24]

It's like he got an engineering degree by asking strangers on the street what they thought about mechanical engineering.

[@Vodd]

Del's Neanderthal ancestor watched the guy who discovered fire and then put it inside his pocket to make a tutorial YouSlate etching

[@allanhughes7859]

I think my life time ambition is to get you two to sit down over a pint but before that I must get to love my mother in law WILL IT EVER HAPPEN ?????????????????

[@scooterchannelanddoityoursel]

Delboys Video is so dangerous, using no thick handshoes while the hot water is let out is crazy ,also protecting glasses are a must during the procedure. Delboy is a danger for every motorcyclist.

[@MotoGoato]

I personally loved the Delsplanation of above and below ...... who would have guessed that something higher than the engine is above it and that something lower than the engine would be below it ..... cheers for that Del, you're my hero ....... 🤦‍♂🤦‍♂

[@pbsgarage3486]

That second bit about the Evens is FUCKING GOLD! I'd forgotten much of that nonsense. Awesome! I'm so glad you have this saved. I don't know if Del's got a video of how a starting/charging circuit works, but I'd love to hear the explanation of that!

[@kaput251]

It's been proven ! It's on the website !

[@ticthedog9413]

Del is a 🔔end, says he's been a mechanic for 35 years and he just hasn't got a clue. Andy's Motorcycle Obsessions did a great video on how a cooling system works, ( just for Dels benefit ) A reminder of Dels cyber bullying of a ex soldier suffering from ptsd may make a good video and his explanation of how a gearbox works I took a cylinder head off a 1992 Ford 1600 CVH engine, the alloy head had been eaten away by old antifreeze. I could send you some photos if they are of any interest,

[@ogKEGGY]

When you do oil changes you should drain all of the oil, and then fire it up, BUT ONLY FOR A FEW SECONDS ! just to get all of the oil from the top end to come down ! And then repeat this exactly 4 times !!!

[@5084204]

Apologies, but this is a mechanical blasphemy. You do not run any petrol engine without an adequate oil supply unless you want to fuck it in seconds. Where the hell did you get that from???

[@pjclark8624]

I didn't see the original, thank god. If water was not the best liquid thermal conductor then EVANS would have sold millions of gallons to all the Fire Brigades in the world.

[@Nbomber]

Yeah, id love to climb under my forester and open the radiator drain cap when the coolant is 90+ degrees. Sounds like a great idea.

[@digger8180]

Yes it is true the majority of shandy drinking, Southern horses hoofs are "that simple ". Message ends!

[@NK-dl2nc]

Christ! I've been doing things wrong for the past 40 years! I wish I could have watched these amazing delboy videos as an apprentice. Gna go out and change the coolant in my truck now....I'll let you know how I get on in A & E👍

[@carl4391]

Absolutely love these videos they have me in stitches 🤣. Please do a review of the migwire exhaust video if you have it since he's deleted it 👍

[@TornadoCAN99]

He keeps stating water in the coolant boils at 100 C....that's only at 1 atmosphere of pressure! As pressure increases in the system, the boiling point also goes higher...120-130 C without any boiling if the pressure cap is still not popping open.

[@mauricevandoeselaar]

You know that. I know that but del doesn’t read this. He is an absolute idiot who has no clue, lets keep it at that.

[@pikeywyatt]

i followed his dis-ructions and now i am dead,thanks dell'

[@sFde46]

stupid question: when you let coolant out of the engine, while it's still hot and pour new (a lot colder) - could that induce thermal shock on components?

[@Pitmanworker]

As you have foreseen - a stupid question indeed. Of course in the Dellniverse the thermal shocks don't exist. You can clearly find evidence for that fact from his own legitimate explanations given in the second video Matt featured. 🤣

[@H-M-78]

Good question. I think Matt talked about that when Del uploaded that steam-video

[@iannsr125]

Forgot to say doesn't he realise why we pressurise the cooling system to increase the boiling point of water , as at sea level its about 99.x but at higher altitudes lower air presure it boils earlier can't remember but I know its bellow 99'c . And any how the cooling system doesn't sit at 110 degrees. My gsxr sirs round 65'c on a cold day and can rise to 105'c when the fan kicks in. Dell is in dream land lol

[@killzone32]

Completely agree as at the top of mount everest water will boil a 68c

[@melthebelgian.5837]

In vacuum it boils at room temperature,

[@nuppy.9117]

How have I never seen this!!!! Its fucking gold!!!! He understands FUCK ALL !!! and he's making himself look a complete fool. Has he had any training? How would a cooling system become hydraulically locked?

[@gafrers]

The hot coolant change is the stuff of legends. Deserving to be reuploaded over and over and over. The best thing is not improving at all and never admitting mistakes but doubling down; also changing story over and over. Why doesn't he starts a career in politics, he'd be perfect for it. 32:00 Matt you are just jealous of his sticker applying skills 🤣

[@ajlog]

33:38 that wire looks to be the remnants of the cut end of the reinforcement wire that spirals inside the hose. It’s probably a vacuum rated hose that uses an internal reinforcing wire to prevent it collapsing under negative pressure. You can see the impression of the spiral on the hose. They are notorious for being a pain to trim flush when cutting vacuum hose to length.

[@prdoohan]

It's either that, or a bit of the electrical wiring harness from the dash hanging down.

[@brentsmith5647]

Brilliant

[@defaultdriftco00]

Awe yes! Spending lunch having a pair of tires installed and watching Del Boy working hard in reverse!

[@buddybonus10]

Looking forward to this😂

[@aussieboy424]

Always remember to have hard plastic edges and be super slippery

[@5084204]

I am slapping my head in disbelief.... What is that guy doing??? 1. You never-ever open closed cooling systems when they are hot.NEVER! FFS. The fluid boiling point depends on the atmospheric pressure. Water in the high Himalayas mountains boils at 80 degrees Celsius. In Southampton - at almost exactly 100 deg Celsius. In the closed cooling systems, you have a silent water(coolant) movement because the system is under pressure, even if the glycol has 180 degrees Celsius. Once you open the cap - you reduce the pressure to the point the fluid starts to boil and will cause damage to you (Salisbury Hospital is the best for severe burns treatment in the south of England!) and to your bike. If you need to clean the cooling system so it looks like the water from your tap - you just flush it with warm water and some acidic chemicals (citric acid is the best, but it is mega corrosive for aluminium, so use it for a very short period only). There is plenty of videos on how you can do that with a simple garden hose. 2. Expansion tank removal. The stupidity of the highest note. Please - have a look at your radiator cap. It has a flap, and the spring and the f...mark on the top: e.g 0.8 or 1.1. that's the pressure when the "flappy valve" gives up and releases excess fluid to the tank. But when your engine cools down and the pressure decreases - the flap allows drawing the fluid back from the tank to the radiator. Removal of this tank is stupid - at some point, you will end up with a minimal amount of the coolant in your system and you will risk engine overheating. If this tank is full and releases fluid - you probably have head gasket issue - pressure from the pistons gets to the cooling system and removes the fluid. Repair is necessary asap.

[@MarkJames61]

Thank you for sharing your own knowledge. Del is Del. Del is a bit dangerous.

[@lv0ll9]

Can already predict this to be glorious

[@grahamtanner559]

It just scares me.

[@jamesallen4050]

33:57 That Matthew, is a tampon string.

[@mickl8212]

2nd video, that expansion bottle does NOT keep filling unless there's something seriously wrong with the cooling system (overpressurised by a blown head gasket). The coolant expands into the expansion tank when hot via the rad cap, then returns via the one way check valve in the rad cap. What's really scary is this guy is posting dangerous BS on KZbin. Someone could remove that expansion tank on their bike, the resulting expanding coolant expands into the open vented pipe, onto the road and the rider goes down because they hit the slippery coolant. He really is clueless.

[@User6327]

Who casually opens their hot fucking radiator near themselves and also brake pads… anyone who has ever ridden motorcycles for real would avoid this like the plague.

[@johnchettleburgh6055]

Legality of safety marking - nothing for the cooling system but it is mentioned for brake fluid reservoirs and also airbags (other systems too). Legislative authorities gets interested if people are at risk of getting killed, not so much if someone is likely to suffer a minor injury through their own ineptitude! However, manufacturers will protect themselves from legal action if people injure themselves, hence warnings not to drink the acid from the battery. If someone were to injure themselves as a result of the warning being obscured by a previous user, then the manufacturer will simply point out that they had taken reasonable steps to warn owners of the risks.

[@chrisyln8808]

just saying not all bus drivers are as thick as Del, remember one won master mind

[@noggintube]

It was a taxi driver wasn't it?

[@ag666999]

Dear Del. Have you anything to say about the Busa coolant "tutorial" video? Did you really think that the removal of the vid makes everything better given that loads of gullible fans watched it and may still think that incorrect "tutorial" was correct procedure? ARE YOU THERE DEL?...we know you are mate

[@grimmreaper3785]

DONT ADD WATER first part adds water

[@greggan100]

His new video just uploaded 🤣🤣🤣 he gets serious, hoodie off and wrestles them fucking tyres off hahaha, also hour to put bike on paddock stands WTF🙈🤣🤦‍♂️

[@g0fvt]

The lying about the Evans Coolant is embarrassing, I see similar BS about it on car forums. Someone sticks a V8 in a kit car with an undersized radiator and it keeps boiling up so they put Evans in it. instant result no steam venting from the cooling system but of course the engine is actually getting hotter still. They just think they have fixed it. Delboy should watch his own videos before he uploads them and do some background research. The nonsense about lubricating the water pump is a classic, the bearing has to remain watertight with about 15psi of coolant pressure without water and steam pissing out of the spindle, but we are supposed to believe a viscous liquid under no pressure will get into the bearing?

[@iannsr125]

In all fairness dell sounds like a salesman trying to explain to you why your cambelt snapped whiles the flux capacitor sent you back to 1985 hahahaha 😆 .

[@Francey4782]

I remember all his Evans shite and Matt's proceeding criticism but that one was something else. Maybe I did see that one but just didn't understand enough about it at the time and just let it slide. Whatever the case, still can't believe he simply took the expansion tank / coolant res jobby off completely. What a load of old Evans! Quite clean, immaculate. Fuck's sake!

[@nemainey6954]

Someone should report Del for pissing coolant all over the roads, I feel sorry for the poor animal that comes and licks that crap up, surely that must be breaking some enviromental law

[@goinhot9133]

With as many people saying they reported, & knowing I personally reported the coolant video, maybe he didn’t take it down & KZbin did it for him? As many people reporting it & quickly, likely caught the attention of the algorithm. Not saying this is what happened, just trying to be unbiased.

[@gafferjoe]

Del reminds me two things, firstly the phrase "in the kingdom of the blind the man with one eye is king" and that remaining eye isn't too good either. Secondly the mentality of a teenager, whose confidence way outweighs his ability, ultimately his complacence and arrogance ends up making him look like a tit. "I think I know what I'm doing" (then just making shit up winging it), isn't the same as "I know what I'm doing." Imagine having the Internet as a resource and still not doing the single hours worth of research it would take to not ruin your credibility by getting caught bullshiting on a regular basis. I really wonder if he cares, like genuinely cares about the mechanical side of things, or if he happened to find out that making videos gets him attention, money and has given him an ill deserved sense of authority on the topic and a purpose as he's had some limited success out of it. He clearly wants to edit and make videos and do left field artistic fabrication, I think he's just a frustrated artist. He should probably sell the spanners, and buy some watercolours, he already has the paper... Stick to just riding the bikes as a past time.

[@jediknight1294]

He has so many years invested in being an 'Knowledgable' authority figure on bikes, running a bike club that was for people too good for us called the idiot collective, working in the industry etc etc etc that he must care or areas he has so much effort invested in being a 'biker' that he can't step back and realise how dangerous he is.

[@k1ckyscotland988]

The burning question Del did'nt answer on Evans coolant. "Do cats like to drink it?". I ain't paying good money for something that does'nt cure my streets feline problem. My Staffie can't be expected to do it all herself!.

[@raywalsh5822]

a classic bus drivers explanation

[@stevenhoman2253]

Distilled water is more expensive than petrol in Australia.

[@archiedentone5950]

Just one mistake you made is explaining the heat holding and shedding of water versus evans. The water sheds the heat better than the evans which is why the coolant mix runs at a lower temperature as it sheds the heat in the radiator. The evans can’t shed near as much and just gets hotter as engine heat increases

[@dirtygarageguy]

I wasn't talking about thermal conductivity, I was talking about specific heat capacity, 2 different things.

[@dirtygarageguy]

And to be clear we're talking about thermal sensors before the rad, not aftet

[@archiedentone5950]

I look forward to your test. Remember you must leave no air space in either container

[@Turbofab]

It's annoying me that 1 he's referring to it as an overflow bottle and 2 he's removing it completely saying its OK to do so, when clearly it is an expansion bottle which takes on fluid through expansion and then draws the fluid back in as the system cools down, Del should come with a danger sticker

[@oyleyhands1332]

Why does a Busa have a broken shopping trolley across the front ? did it smash into one somewhere ?

[@dan-bird7846]

police " so mr delboy i hear you are being bullied by the workshop? ", del "yes", "ok how exactly? ", "i'll come back to that". I think del saying i'll come back to that is his version of no comment

[@blowduke]

Did del work as a double glazing salesman , he’s made for it .

[@Davidthomasv8]

He's covered the valve Matt and the warning god help us

[@DC73rr]

So realistically speaking. After eliminating the coolant expansion bottle and letting the radiator cap vent to atmosphere. Delboy could go for a LOOOONNNNNNG ride on a HOOOOOOOOT day. And effectively, drain the coolant from the bike as he rides? And. How would you know if the coolant level is low, needs a refil, or, some other potential leaking problem? WTF?

[@sexyfacenation]

Nope.

[@Jeffrium]

I think I know where that heating up your engine before draining the coolant comes from, back in the day when we wanted to take the engine out of the car, when it was winter the hoses became really stiff and it was hard to get them off so what we did was we took the radiator cap off when the engine was cold and then turned it engine on and after a minute or two turned it off and the hoses were softer and easier to take out , we couldn't really burn ourselves because the coolant was 40c max!

[@ANDY5]

This is the result of cousins fking

[@TheJmebe]

Amazed that the coolant didn't boil and spurt out when the system was depressurised. Even more so when it was repeated with pure water. Dangerous.
