Does the DeWalt 108 Piece Mechanic Tool Set ($70) consist of all the tools I need on order to change spark plugs?
I was wondering, did you buy spark plugs from dealer or from an automotive store? Because other videos made it seem that the gap on new spark plug should be looked at and might need adjustment to specs? Which ones did you buy that you trusted to pull them out and straight into plugs? And how much? I have same vehicle for wifey.
Thank you
What is the hose called that is right above the ignition coils
wow made it look super easy also side note your wife’s engine bay is very very clean nice work
Thanks for the video. What size of spark plug spanner to use. Is it the same for C200 2010 model
ocd alert, oil filler cap facing wrong way !
Mercedes wanted $360 for this
they want 250 $ at the shop is that good price ? c 250
Wow that simple. Thank you for this video very informative.
How do u know when to change them ? Is there any codes ?
Okay so I do my spark plugs all the time my self right and this time im running in to my first problem I changed all 4 spark plugs but still get a mis fire do you think I’m tightening them to tight? I bought new coil packs and it still does I’m the same thing only in cylinder 3 sumtimes in 4
Ps I’m outside now doing them again replacing all 4 spark plugs this is the 3rd time I’m replacing them and only replaced the coil packs 1 time in the last 3 days before all this happened I don’t my spark plugs about 6 times with no problem and the coil packs 1 time with no problem
would anyone know if the transmission fluid needs to be replaced at 60K or 6yrs? On this same car?
Hi I would like to know what is the torque force for fastening each sparking plug?
I have the same engine in my car. It makes an odd sound during startup. Almost like a stalled engine. It only has 70k km on odo.
Do I need too disconnect battery before unplugging the coils?
