Spark plug tool
« on: July 28, 2010, 04:38:24 pm »
What size socket do I need to get the old sparkies out? Need to get a sparky removal tool.

Never mind. Found out. Spark plugs are 10mm which is 16mm when referring to standard socket size  :stupid:
Hence need a 10mm spark plug socket. Which genius thought this up?

a 10mm spark plug socket has a 16mm hex size. I believe that the 10mm relates to the diameter of the ceramic element of the plug as most plug sockets have a rubber insert that is just smaller then 10mm internal diameter so it grabs the socket to allow it to be removed from the plug 'hole' easily. Another useless fact is that a 16mm spark plug will have a 14mm thread with a metric 1.25mm pitch.

some tips: when removing the plug its always easier to do on a hot engine than a cold one.  Re-installing the plug: push the plug into the socket and then into the trhread, turn counter clockwise by HAND until you feel a click this means that the 2 threads are aligned and will tighten in without cross threading. Tighten the plug by hand and then torque up tight, release the plug and then tighten with a torque wrench. This crushes the compression washer and then retightens it to the right torque meaning that the plugs wont be lower than the desired torque once they heat up.

Bored yet? I could go on.....

How do you tighten by hand on the TFSi as they sit at the bottom of the Coilpack holes  :confused:

Awesome info PDT. More is definitely welcome.

What about the use of anti-seize?

Bump.

I am very interested too.

Just to clarify. You nip up the plug with a normal socket and wrench. Then slacken off before using a Torque wrench.

Also what is the correct torque?

And what about anti sieze?

Think the torque is 20-21Nm.

I use a Draper spark plug removal tool, it's excellent and if I remember only a few quid...

Here it is;

http://www.tooltrolley.co.uk/product_info.php?products_id=31882&manufacturers_id=268&osCsid=18be283a5e846dc058b5fe72d1fbcf59

Anyhow, all you do, is simply push that into the hole, it locks into place on top of the spark plug, then twist it to loosen, keep turning and then pull gently upwards... The spark plug will then come out with the tool :)

Fitting is a reverse of the above, do NOT overtighten, all you need to do is tighten it just enough - basically, so that you wouldn't need to wrestle with the wrench tool to remove it next time... Turn it until it is very tight - just not over-tight.

It's very easy to do, but very satisfying fitting new plugs - I did mine last week.

Put it inside the socket then turn that with your fingers.

Never in 30 yrs torqued up spark plugs, you certainly can't with a tool like this ^^^

Always used a socket set.

Any more comments on anti sieze / copper grease for the plugs before they go back in?

+1. I bought both the spark plug socket and the T-bar socket tool. Also bought some anti-seize copperslip grease too.
