That nut is tough to break from above, but I've had good luck w/ closed end wrench and hammer hits on wrench from below.

good luck

 

I had trouble with that nut too (on an Integra). The nut is pretty shallow with it's flange. Most sockets have a taper on the end, so I took one (think its 14mm?) and ground the end some. (Make sure it stays square) Now the socket had sharp corners and grips better on that shallow nut.

 

I think what everyone is failing to read is that the NUT IS STRIPPED ROUND. The New one is on its way, the hard part is going to be getting it off..

 

Then take a dremel with a cutting wheel and cut the nut off.

That sounds like the only way to take it off to me.

I prefer to use my 4.5" grinder with a cutoff wheel but I do not think you have enough room to get in there with a wheel that big

 

There is not a ton of space in there to get at that nut. If you have the side motor mount out, you can try to raise or lower the engine a bit to gain better access. Use a piece of wood between the jack and the oil pan.

The timing belt cover should be able to be removed with that tension nut still on.

I would probably try vice grips. If you have a punch, you may be able to break it loose by hitting the left side of the nut from the top with a punch/hammer.

Google Craftsman striped head bolt remover. I am not sure you would have enough space between the sub-frame and the bolt head to get that style of remover in there.

 

To the O/P: You'd be surprised how little surface area of a nut/bolt/screw that a punch needs to drive it loose. The impact of the hammer (I prefer a heavier ball peen hammer) on the punch creates a very tremendous force. There are also extra-long punches.

But, everyone one has their own ways and suggestions...

 

Yeah, sometimes I gotta learn to pay attention a little better.

 

This is what I use to cut off nuts that have rounded

 

Anyone had any luck with this?
