Here's how ya do it.
Don't laugh. Someone else showed me.
Know what ya do?
Take a hack saw and cut the waterpump at that area, so you can apply vise grips and get that bolt out.
You are wasting your effort. Get the hack saw and start cutting away the waterpump. Oh, It's aluminum, cuts easy.
If ya can't cut, go get a file and cut into the aluminum to get to that area, also. May need a jewelers file and LOT OF PATIENCE!
Want to tow it to a mechanic for that one bolt?
I thought so!!
You can do this, lots of patience is the key.
NEXT TIME, break FREE EVERY BOLT, NOT ONE AT A TIME. You put extra tension on bolts which also helps prevent the last one from backing out easy!
I learned that one, too!
It is steel rusted into the cast iron engine by the water from the pump. Common.
When you reassemble, go get new bolts (as many as needed). Put film of oil on threads (FILM NOT MORE) thread each bolt in & out before you reassmble.
Then wipe off grease on the bolt hole, wipe face of parts with brake cleaner, wipe off with paper towel (you'll see it clean, if not do again!), then apply gasket material & gasket sealer, Let it cure for about 10 minutes. Reassemble, firm tightening all around in a circle.
Let it sit overnight.
Assemble with the NEW HOSES next day. CHECK CHECK CHECK ALL CLAMPS.
(I didn't, lost my first engine as the bottom hose burst off the radiator, I didn't tighten enough).
BEFORE YOU GO MUCH FURTHER. DOUBLE CHECK YOUR BALANCER & TIMING CHAIN FOR WEAR. If ya have over 75,000 mile on the engine & it's never been replaced, I'd DO IT NOW!.
You are already 2/3 way to that part of the mission (chain behind the timing cover, you have now exposed).
Chain & gasket is $50-ish delivered.

This is long answer, but worthwhile information.
Especially if ya plan on keeping the car for a bit longer. Your car will be so happy & so will gas milage, it'll go up!

I'd have to disagree with putting the oil on the bolts; some of those bolts go through water jackets, and you need to coat the threads with a sealant. I've always used blue RTV in-a-tube, but I hear the proper stuff is the teflon "PST" compound.
