it is not 19mm socket,
i try 21mm, but it does not grip .

what socket or tool i need to take it off?

 

uhm...a 20 mm?

 

Are you using a 12 point socket?

 

no 20 mm in any hardware store
i was using 6point socket with impact wrench.

 

weird. on my 06 the 19mm worked fine

 

WOW Im glad i caught this. Dont take it off just yet. I was talkin to one of my friends and he said that you will need an air wrench to take off that bolt. I cant quiet remember exactually what he said about it but if u take it off with a normal wrench u will f your engin up. I could be wrong but be careful!!!

 

i have air impact wrench, just need to know what kind of socket get use. I even bought those Black impact wrench socket.

 

here, use this

You dont have to use an impact, and it wont mess up your engine if you dont. However, it is much easier obviously with an impact since you dont have to deal with the engine trying to turn over.

 

Wow thanks for the info. I have been looking all over for an air wrench because i have been 2 afraid to try it otherwise.

 

You can use an electric impact wrench. Works like a charm.

 

i need to know what kind of socket to remove it. Hexagon socket does not work.

my bolt does not look anything like his.

 

just try different sizes till you find the right one. only thing i can tell you because mine looked like that picture.

 

yeah my bolt looks like the last one.

 

As I asked before, are you using a 12 point socket???? That is what you need to be using.

 

looks like the edges have been badly flatened. might have to replace it when you get it out. good luck

 

i was using the 6 point 21mm. I haven't try the 12 points yet
