02 GTX DI Spark Plug Torque Spec

[Thomas Zadrozny]

Does anyone have the correct torque for the spark plugs on a 2002 GTX DI?

I have never heard of any one useing a torque wrinch on a spark plug in the 20 + years I have been repairing engines I guess I may be learing something new. If I am correct I would just turn them in untell they are snug not useing as much force as you would on a bolt the same size as I have never seen a spark plug come loose. :cheers:

Generally, you are probably correct, but why take a chance on damaging cylinder head threads due to over tightening. I still like to verify correct torque especially when installing a set of new plugs in a aluminum head. I would still like to check this.

There has to be someone out there with an 02 GTX DI service manual that can provide me with the correct spark plug torque.

Thank you

What I am trying to say is stop way sooner than you would with a bolt that same size. I like to use antiseze on the threads to make them easier coming out but like I say you should not tighten them so tight that there could be a posability of them striping when they are removed. I have never seen a spark plug come loose in over twenty years and the only way that I could see you striping the threads is because you crosed threaded the plug or you did not listen they do not have to be put in very tight just snug. I am prety sure that there is not anyone here that have been working on engines for any time that use a torque wrinch I have probbly seen 1 or 2 at the most plugs stripped out of a few thousand engines and the only cause that I can think of that caused it is that someone put in way to tight or crossed thread. If no one can give you a torque reading and it is important I can take my snap on torque wrinch and let you know how tight I would put one in but remember I am no pro but I have never had a spark plug problem. :cheers:

:agree::agree: Robin is right. To kinda ease the pain of having a number here is what the manual says for your plugs to back up what Robin has said.
"Hand-tighten then tighten an additional 1/4 turn"

My book says 17 ftlbs but I am not going to grab my torque wrinch the next time I replace my plugs

Yeah but for his it says that. Most manuals I've looked at do have a torq. number but for his model and year that's what it says.:cheers::cheers:
