OK....maybe I've been retired from turning wrenches too long. I'm replacing spark plugs on the wife's 2001 Olds Aurora 3.5, and I'm stuck. Has the newer cartridge type ignition coil setup with no plug wires. I pulled the cartridge off no prob, the boots of course are on the plugs, down deep in very narrow holes. My plug boot puller tool (circa 1975??) won't get down in there to be able to grab the boot securely to remove them from the plugs. And of course I can't get the socket on the plug without pulling the boot.<br /><br />My GM service manual calls for a "J-43094" boot puller tool to do this. So I figured maybe I'd buy one. But an internet search for this part number reveals absolutely nothing. Haven't called a dealer yet, but before I run off in prayer of someone having a tool that fits and choking up $50 or something stupid for the tool, do any of you have a better suggestion for me getting these off without risking boot damage? Or what brand/model of boot puller tool do you guys have that fits in this motor? I was tempted to get a couple sets of needlenose and just pull straight up on the boot, but I'd hate to tear 'em as I'm sure they're not cheap. And even if that works, the real challenge I suspect will be the rear plugs against the firewall, but I can't even get my tool to pull the obvious ones in the front.<br /><br />Help?! Thanks in advance.

Re: GM auto techs, help please!

What you got there is a 'direct coil over plug' ignition.<br /><br />After removing the bolts, you need to twist the coil (gently) from side to side to release the boots grip on the plug. But that's too late now :( . I hate the 3.5L, the plug holes are way too deep. <br /><br />This is what I have tried at various times - long nose pliers, thin long blade screwdriver, circlip pliers (the ones that open rather than close) and just (gently) forcing the plug socket over the boot. If there is oil in there (common), you need to remove the rocker covers and replace the seals. Oil will make the spark plug boot bloated.<br /><br />Aldo

Re: GM auto techs, help please!

Thanks for the tips. I'll be sure to work the coil a bit when I get to the rear...haven't broke the seal on that one yet so maybe I can get them to pop before I pull it up. Sounds like I just need to get a bit creative to crack the seal. Thought about making my own tool out of a coathanger as well, but not sure if it'd hold. Anywho. Last night I just slapped it back together so the wife could drive it to work today. May try again tonight.<br /><br />Thanks for the tip on the oil, the front one was clean & dry so no prob there, and if the car gods love me the rear will be the same.<br /><br />If anyone else has a surefire method, please share. Thanks again.

Got 'er done. Turns out I just had to get brave and be more aggressive with twisting the boots off with a needlenose. With some force, they all popped off cleanly without any damage. She's all reassembled and freshened with new plugs, pcv valve, fuel filter, air filter, cabin air filter, flushed brake fluid, cleaned throttle body, and it's running good. Also paid a local shop to do a trans fluid flush with their machine & replace the filter. So now I just gotta do the coolant flush and she outta be good for another 60K or so.<br /><br />Thanks again.
