Trying to get the water pump off after it failed. All the bolts are out bar the bottom two long bolts which are stuck solid. I've snapped a spanner, split a hex bit and finally, rounded the ends off.

I bought a set of Irwin bolt grips and they have been of sod all help.

Any advice, given that I don't have a blow torch and don't want to have to take the radiator off.

I used to repair outboard motors, so I know what a pain seized bolts can be. You could try soaking in lots of penetrating oil and hammering on a smaller socket to get a bit of purchase on it. If not, you could cut the heads off the bolts, remove the pump and mounting block, so you can see the studs going into the block, then weld or get someone else to weld a couple of nuts on the studs so you can get a spanner on them. The heat from the welding will help loosen them up. If all that fails, you'll have to cut the studs flush with the block and drill them out and re tap the holes. Seized bolts are a curse!

Can't hammer them on without removing the radiator!
Tried tapping them on with the small amount of swing I can get to them, but to no avail.

Have you ever used these?

Mac Allister Grip Drive Socket Set, 7 Piece, 5052931117833

they work different to the irwin jobbies and I've never heard a bad word said about them.

you will probably find that it would be better to cut off the heads as mentioned above as it will be the bolts seized into the pump and mounting block rather than the threaded part.

Finally got the bolts out! In the end I had to use a hammer and chisel to break off the housing around the bolt, then use Irwin bolt grip on the remaining stump. The final bolt looked like it had been bent before it was screwed in originally. That was fun!
