Snap... Goes the water pump bolt...

I was in the process of trying to change my water pump and snapped one of the bolts off on the left hand side.

So now I have two show stoppers that I have to take care of before I can put this sucker back on.

I have two questions:

1. It is possible to get a set of high quality water pump bolts to replace the ones I have in now?

2. Anyone know the size/dimensions/thread type of these bolts so that I know what to ask for?

2. Since the thread of the hole is pretty far in, what could I use to get the rest of the broken bolt out and would I need to fix the thread as well when I do this?

I really am hoping to avoid having to remove the timing cover.

You can call arp and tell them the length, and size of the bolts you have. They will match what you have with arp bolts. There is no specific kit for our cars. Found this out after ordering 2 differnt sets.

Depending on how far in the block it is, there is a tool called and easy-out. It is basically a reverse drill bit. You use a small drill bit to get a hole for the easy-out then use a ratchet and lots of luck and elbow grease to unscrew it.
 
Like was said, an extractor kit would be your best bet but youd probably be better off taking the timing cover off to make sure youre actually drilling in the center of the broken bolt. Then an extractor gets put in with a ratchet counter clockwise. Easier to do it right the first time. Plus youll probably want to chase the threads of the hole after the old bolt is out because theres likely something causing it to hang up if you broke it. You might want to clean the threads of the other bolts on a wire wheel too, they look a little rough.
 
... Be sure to use anti-seize on the threads of the new bolt ;)

Yeah. I put anti-seize on every nut or bolt I take off and put back on - car, home everywhere.

Also, as far as size of the bolts, you can take the bolts to HD or Lowes and in the bolt section they have sample nuts where you can screw them into and get the size that way. Put some heat on the broken bolt that should help.

Str8stang, have you used that kit. I know when I was building my engine I purchase an ARP engine bolt kit and it was basically worthless for our cars so I sent it back to Summit and just reused the old bolts.
 
I ended up pulling the front cover off to get to this sucker.

I was a bit pissed when I could unscrew it using the tips of my finger. I guess I can look upon this as a opportunity to change the timing chain/sprockets (312,000 miles on it).
