Through the wheel well and under the steering. Put the socket on the plug. slide the rubber boot up and turn the flat spot down. 6" wobble extension just fits in the socket.

if u go to autozone they have a 5/8 spark plug socket with a built in swivel and it is the perfect length. i was amazed at how easy it was once i got that from autozone. ive got tons of extensions and swivels but they where always a tad to big and put stress on the plug itself and could cause a hairline crack or break. with the socket from autozone their was no stress at all on the plug. it was meant to be!!

 

Definitely no need to move the steering shaft & don't even have to roll up the rubber sleeve.

Shorty spark plug socket like this one I have from Trick Flow -

Along with a open end or ratcheting wrench and its no problem.

 

or again just grab the socket at autozone for cheaper

 

I tried the shorter spark plug socket, but I couldnt get an open wrench on it enough. I cant move the rubber sleeve because someone put a brake line litterally touching it. these i believe are original plugs also but it ran good i just changed because I recently purchased it and want everything in maintained order.

 

dont get the shorter socket u need the one from autozone its a 5/8 socket with a built in swivel. it is perfect fit

 

Hey there
try using 2 swivel heads and a 18 inch extension and go through the wheel well

 

with the length of the regular 5/8 sockect and then the swivel is to long and adds to much stress to the plug it binds! it can be done but u have to be careful. if u just get the socket with builtin swivel from autozone their will be no binding up at all. i will take a picture of it for if u wish. its almost like they made this socket just for these blazers lol.

 

I bought that swivel spark plug socket today I will get a chance soon to finish the job but were getting a snow storm again tonite thru tomorrow but I can see why this socket would get the job done

 

ya let us know how it goes. im telling ya that sockect makes the job so easy for the #3 plug.
