Its not related in that its not as easy to find and its just general information, its not explicitly or solely related here. But nevermind I guess.

And I mean im not the most familiar with the car but it appears that the 4 bolts are what hold the whole unit on, the flat surface just appears to be a machined piece of the block they attach to for what I assume is ground.
Are you thinking the top 2 bolts allow the whole thing to be lifted off?

Gonna look under the hood in my driveway......brb

SaturnGirlFromMars 10-10-2018 11:55 PM

Haha okay

Darn I think I killed him. RIP

OK,

My apologies.

The bolts we speak of are one in the same.
The others were pigments of my imagination.

I have a 97SC2 and my coils are mounted on enough of an angle that I can establish line of sight to the bottom bolts.
Don't know what else would be blocking your path. should be able to use a reg depth tool (see below)


Try an appropriately sized stud removal tool. It obviously can't be too large in diameter nor too deep.

Or try these

Basically, you hammer them onto the damaged head, then put a regular depth SIX POINT socket around it and slowly apply force to break it loose. The last thing you want to do is break it off.

You may need to use a wobble adapter to make up for the fact that you can't get lined up right over the bolt with the ratchet. I prefer them over u joints

Then beat the stripped one out of the bolt remover and repeat for the other bolt.

If even these won't grip, try to dremel shape 2 parallel flat edges on the side of the head of the bolt so the extractor has something to grip

No, I went and found that link for you, thouigh Sears is going bankrupt on Fri so not sure I'd order from them.
Check out the link so you know what they look like

You stil haven't told me what donzo is.....

Do you know who Bonzo is?

SaturnGirlFromMars 10-11-2018 12:34 AM

Those socket tools appar to be very large, not sure if they would even fit around the bolt to be honest. Do you think I might have a chance with vice grips? Or dremmeling down to 2 edges and putting a wrench(obviously 5-7mm range if its 8 normally)

Do you think the other person suggesting grinding off the head wouldn't work(such as the threat actually threading into the module versus just the block)

derf 10-11-2018 12:35 AM

Fixed all my misspellings. I don't get paid to type here.
Actually, I don't get paid at all

SaturnGirlFromMars 10-11-2018 12:36 AM

Donezo is a funny way of saying SOL. hehe

If your dremel cutting wheel is not the right size, it won't fit in the gap. If it is too small, you won't be able to cut all the way through the bolt. I'd save that as a last resort.

The bolt extractors for the smaller sizes (my set only goes down to 10mm (3/8 " drive)) are not much bigger than the bolt heads.
See if you can find a 1/4" drive extractor set. It should have the size you need.
Also, stud extractor sockets come in different diameters, so don't write them off -- by far the easiest

You can also take a hammer and point chisel and make an indentation on the outside rim on the top of what's left of the bolt head. Then strike the chisel so that you impart counterclockwise rotation on the fastener. Sometimes this breaks the rust free from the impact,
