Picked up this socket tool at the flea market this morning. Made by
westward iubf9. Tried it on #3 plug and it went right to it with NO issues. Pretty handy tool.plenty of room for the knuckle etc. Got it new for $3 bucks. Looking around online I finally found it.

yea that is handy my dads got one but i used a swivel extension for plug 3 and it works out great

 

a must have for blazer owners

 

I ended up using 2 pass-through sockets stacked on top of each other with a box end wrench. Annoying... I like your version better.

 

Wicked. congrats on the find!!

I managed to use a cheap dollar store socket with the rubber taken out to get it out... before I had the BL, now it's a piece of cake

 

I have been working on these things for the past 10 yrs. About 5 yrs ago an old GM flat rate mechanic showed me an easy trick for this.

Support the truck under the frame with either jack stands or frame lift about 2' off the ground

Put block of wood on floor jack and put under oil pan, slowly jack up pan & you will see the engine rasie slightly.

This will rasie engine high enough to clear steering shaft if you go in through left wheel well.

Hope this helps.

 

Yea ive done that too. Helps! But cool thing is this tool here. I just stick it in the wheel well and turn lol. No more sliding a 80lb floor jack on the gravel.

 

i have not needed and special tools to get to any of my plugs. i just go right though the wheel whel and all good
