%!@$&!!! I broke two bolts off putting the water pump pulley back on.

For a small bolt like this: slot with Dremel use impact work flat blade bit

That'd work perfect!

I've used dozens of times and yes works amazingly well. I also use the method to install the from the back bolts that hold the rear wheel bearings on e53. You can turn the hub to align the bolt and a long flat blade will reach through to snug up each bolt then you need less than 1/4 turn to torque them and with two wobble extensions you can work around the CV joint without removing the axle or the suspension or the exhaust

If the bolt on this case is submerged you can likely use a hardened chisel instead of Dremel to make the notch and a hammer strike impact screwdriver to turn the broken bolt since the impact works to push the blade into the groove

Unless they ended up cockeyed from getting snapped off you should be able to turn them even from the back if they protrude enough.

Thanks (all). I guess I really ought to pull the pulley off and try before I order a new water pump (the fan and shroud are back on, but I'm getting experienced at taking them off). I own a nearly new pair of needle nose vice grips. But drilling old bolts out is Greek to me. I guess I'm wondering if I can drive to the hardware store (5 country miles) to get new bolts before I pull everything apart?

Thanks to the help I've calmed down and realized it's not a huge disaster, just a minor inconvenience.

Bicycle? Über? A nice walk in the country? Not worth the risk to drive.

You've got a small problem that will become very big if those last two bolts go while you're driving it.

Understood.

Remember when you put them back on the torque is 10Nm or 7 ft/lbs

Thanks, I will. I have a rough idea what that is even by hand, but I'll borrow a torque wrench from my local O'Reillys if the one I ordered doesn't arrive.
