Default Tips on breaking upper motor mount nuts?

Besides PB Blaster, any other way to turn these two side nuts? Used pb blaster, and they are on for good. No room for channel locks. What to do?

[edit]
These nuts are stripped a bit. What can I do?

I usually put a 15mm 1/2" drive socket and short extension on my 1/2" ratchet and turn counter clockwise. Or use the impact gun.

I dont get it. Whats the problem? Are the nuts rounded or something? They're usually not that tight, just a 15mm, extension and rathet or breaker bar is all you should need.

NAPA sells a set of nut extractors. They're reverse threaded like easy-outs but are meant for nuts instead of bolts. Get the expensive socket or set (if you can), I got the cheap one and first try I split the stupid thing in half.


Oh, dunno if it was the problem or not but never use 12pt sockets on a hex (6pt) nut/head.

...
The proper way to fix a S-Series automatic is to replace it with a 5spd O:)

Default Re: Tips on breaking upper motor mount nuts?

you could try grinding the nut(s) down a little with a dremel and then hammering on the next smallest size socket. oh, and do use a breaker bar like Low suggested. a longer bar (wrench handle) gives you greater breaking torque for less effort on your part.

Or you can remove the bracket that the top mount mounts to. Then put the nuts in a vice (ouch!) and remove it that way. The bracket it attached to the frame rail with four bolts.

I cut rounded nuts all the time with a dremel tool it isn't the fastest way but gets the job done clean. Do it when you are fresh and not in a big hurry will probably take a couple of cutter to do the job I like to cut the nut on each side then it falls off and leaves the threads in good shape. This is a good job to do while sipping a good beer with some nice music playing in your headphones...

No, I didn't. I didn't round them off, either. I don't think they were as bad as they finally ended up, but they had gotten their start elsewhere.

I just ended up stopping at the dealer last night and a tech used his socket to break them free.

Sorry about my frustration, people. It just sucks when you finally get a chance to do something that you knew you had to do since before you bought the car, and to find you can't do it because someone rounded off a couple of nuts. I work too much, and don't have any time at all for problems. Saturday is my only day that I can start something, and hopefully finish it. That said, I woke up early today and changed the mount. Couldn't find a piece of good wood, so I used one of my synthetic burning logs. After I lowered the engine and pulled it out, I found it cracked straight through the middle. The upside, I guess, is that it's so soft, it couldn't possibly dent the oil pan and I'll light a fire with it tonight.

[edit]
Oh yeah, almost forgot. The mount that was in there, was one of those frowny face after market ones. Part of the rubber near the bottom was cracked half way through.
