What tool req for removing head bolts?

[kroos268]

Removing the head today. I see head bolts below cams; and possibly 2 down the middle. This doesn't look like a tool I have. What's the name\size of this tool so that I can pick it up early this morning?

thanks

Its a giant Allen Wrench there are two types, one looks like an "L" and the other one come as a ratchet attachment, I cant remember the size but I think it s a ??20??

Do not remove the ones in the center those are not head studs, only the ones under the cams

Im pretty sure its not 20 thats a big ass hex socket. Its most likely a 10mm Hex Socket. I know on the CA its a 10 Hex.

and don't forget to remove the head and cams in the correct sequence.

My bad i Just checked it it is a 10 get the one for a ratchet so you can attach it to a a breaker bar

Its been awhile I knew there was a "0" in there lol

10mm hex socket. Buy a quality one, they're tight enough to twist/break a cheap tool. I've even got a Craftsman socket that looks like a pretzel due to some fool overtorquing the head.

What is the sequence??

[Andrew Bohan]

the one that's specified in the FSM

if you're doing that kind of work, you should probably have one anyway.

Crosswise Outside -> in for removal crosswise and inside -> out for installation. Every engine is like this. The #'d bolts in the FSM help to illustrate this point. Do not remove cam caps or a head on any aluminum motor... hell any engine, straight front to back or back to front :)

make sure you loosen the bolts by steps instead of all at once.....that leads to head warpage
