Just did spark plugs on one of these motors for the first time and those ignition coil boots are an absolute pain in the ass to take off if they have never been removed before. You have to pull on them till they almost break.
Well you also need to pay for a quality shop, no shop with a $100 or less labor charge is going to do this. Dealers do this a lot and so do really high end independent shops.
Looks like you skipped another crucial step. You should ALSO vacuum out the spark plug holes when the spark plugs are removed. (whoever is reading this, look in the spark plug chamber after it's removed.. you'll see a lot debris).
Excellent work, especially the thoughtful clean up. But only thing I would say, do this on any engine from anyone. No engine likes debris in the cylinder, although I bet some are more sensitive than others.
What is the correct method to remove the glow plugs? I have seen people using a torque wrench for removing the glow plugs. Is that the correct method and would that be a normal torque wrench or one that has the option to losen with a specific amount of torque? Is it advisable to remove them with a cold or hot engine as there are many different opinion on this? What if the engine can't be hot because of the fact you need to remove some parts in order to access to glow plugs?
You were doing so good by blowing out the spark plugs holes with compressed air….then immediately after you use an air ratchet to remove the spark plug….Dayam dude. Just set the car on fire next time. Never, ever , ever use a freaking air ratchet or powered tool to remove a spark plug . Good way to get fired at the dealership.

@Dnasty1 If I'm not mistaken, using an electric ratchet can break the glow plugs as it can put a huge amount of torque on the glow plugs. When you remove the glow plugs, you want to use the right amount of torque. Therefore, using a torque wrench is the best thing you should use
If your Mercedes is not that old, you don't need an air compresser.. Just change all the coils and spark plugs and it will run like new. But make sure you get good coils and spark plugs recommend by the dealer or mechanic. Coz some spark plugs and coils are cheap and will go bad quickly if you get the wrong ones. I had similar issues with my truck when staring it.
Yeah unfortunately I'm a mercedes mechanic I can say I'd run from any of the newer gens. I personally drive a 2002 e320. I trusted up to 2013 but even now they're awful for our customers. We have a customers with 30k-50k that already needs 2500 worth of oil leak repairs regularly, front diff seals fail normally, rear springs break normally
We need more ppl like u

I wish my shop cleaned my engine bay lol
That’s the difference

You blow them out not vacuum them out 🫶🏽

exactly!!
This is a video for morons who think electric tools sound professional 😮
Don't forget to ask for free carwash with your $800 oil change.
😅

@@mbz4652if I use a low torque rated electric tool I should be fine then?
Does these spark plugs come pre-gap ?
Excellent
Hey man I been looking for ya page I think my girl needs all this lol
15 nm was the torque?
How much Miles/Km it is needed?
just dont drill them out like that always with hand pls haha if they break your in big trouble
My mercedes keeps misfiring should i replace them or just try blowing on them first with the air compressor
the compressed air does nothing except make sure dust doesn't get in the spark plug holder when youre replacing them
@@wingandwang5634 I did same as you.
Only for spark plugs replacing I bought a small air compressor. Next time I can use the compressor again.

@@albertol9654 yeah i ended doing both and it was a coil
Is that ticking noise at idle normal?
Right I have a 19 e 300 and my engine seems "loud" like that
My 14 c300 sounds like it so i assume so.

How much do you charge to change spark plugs on a 2018 s560?@@UnitcrGy
My 2015 with 185,000 miles has no tickie noise
Do you apply anti seize on the threads?
no it takes too long.
German OEM plugs are nickel coated plugs so they dont get jammed in our aluminum heads
Do you use anti-seize on the spark plug threads?
