Title: Removing AAZ Head
Post by: homerj1 on June 12, 2008, 04:38:59 pm

I'm removing a AAZ cyl. head from my 95 Golf next week.
 Can anyone clarify the type of socket required to move the head bolts?
 It was suggested that a "special socket" is required - and since I don't have close access to the car, I can't check.

Thanks

Triple square, like these (http://buy1.snapon.com/catalog/tools.asp?tool=all&Group_ID=378&store=snapon-store). Get good quality ones!!

Not off the top of my head. 10 mm maybe?

IMPORTANT SAFETY TIP (which you probably already know):

Loosen them slowly, incrementally, and in the diagonal sequence listed in the service manual:

else warping may result... the factory spec for straightness is very very tight (2 thou).

Thanks!

Final question:
On the official VW tool, I found on the Internet, the trip square
12pt part is about 4 inches in length. http://www.toolsource.com/head-bolt-socket-3452-audi-p-92548.html

Is the shank length show on this tool necessary to clear something on the head?
Or can I have a short shank and just use an extension?

I can get the 12m 12pt with a short shank locally.

thanks

Should be no problem with a shorter one and an extension.
