Ok. i got the torque wrench which i should use.
it is a cheap one but i think it meets standards.
before continuing, here is the photo of damaged parts…
you can buy it on the internet. yeah… but not that cheap and need to cut & split the original wiring harness.
VW CC TDI (2014), you need 10mm long plug socket for this.
and everyone highly recommend you should spray penetrating lubricant at least several hours or 1 or 2 days!
yes, i think you should. i also have to put a lot of effort into the wrench for releasing glow plugs.
here are 4 damaged glow plugs.
now, time to assemble brand new glow plugs.
before that, i again highly recommend you should clean up plug socket.
there is so much sludges and it will prevent you tightening the plugs.
how to? blow with air gun or… wipe out…
i spent so much time for this.
Because of the sludge, the plug was not fastened properly and after turning it two or three times, it would not turn any further.
if everything is ok, After about 25 to 27 turns, each about 1/4 turn, you will need a torque wrench.
Torque specification is 15Nm.
about cleaning the plug hole. i use wet tissue with thick wire. First, be careful not to damage the wet tissue.
Wrap a wet tissue around the end of the wire and push it into the plug hole. Then, turn it clockwise little by little until it engages the screw threads and is fixed. Do not turn it too tightly, but turn it moderately and then loosen it again. Repeat this process several times (5 to 7 times?). that’s how i clean up.
