Sheered off bolt in block whats the best way to remove it?

[72mk1escort]

My water pump bolt has somehow fractured on my cross flow its the one that holds the alternator bracket and watererpump to the block there isn't enough thread to nip it up so somehow ive got to get the broken bolt out of the block. I was hoping it can be done with the engine in the car by removing my rad etc for easier access. 

 

Ive got all the parts i need for the job a new water pump bolt and washer set from retro bolts and a new waterpump gasket etc. The thing i need advice on really is whats the best way to remove the sheered off bolt from within the block as Ive heard easy outs etc can snap off and leave you in a worse state. 

 

Ive got plenty of good drill bits and a good drill etc and a 45degree angle adapter for my drill so just really need a bit of guidance on how to tackle it as im scared about messing the block up if i get it wrong 

 

Any advise would be much appreciated.

 

cheers guys

Lots of oil soak before u start drill the centre with a lot smaller hole then try the easy outs

[Fern370]

Use a dot punch or small chisel to try an tap it round on the treads

that sounds like a good idea

 

any advise on what make of easy outs to buy don't want them to snap easily

I thought i had problems last weekend,i snapped off a bleed nipple in my willwood caliper.I drilled it out so far so there was'nt much of the thread left in there then went to screw fix and bought a kit that when you srew it in it draws the bolt out.it was easyer than i thought it would be.

if you have a mig welder, build the end of the broken bolt up with spots of weld then put a nut over the blob you have built up and weld that in the centre, then hopefully you can undo it without drilling anything. the heat from the welding normally loosens things up.

That Sounds like a very good idea. I will give it a go

 

Thanks for that mate

The bolt will probably be loose anyway if the head has snapped off. How did it snap?

Had this exact problem with the last motor in the escort but on the top water pump bolt and it was a bit of a brown trouser moment!

Thought about those easy out left handed thread things but seemed so risky as there case hardened and it would have left a bigger mess if it broke as well.

In the end I got some of those small cutting discs for the dermal and cut a slot in the end of the broken stud, heated it up a little, gave it a few taps with a small chisel and then wound it out with a broad blade screwdriver.  

Hope this helps

Basically it snapped from the vibration of the engine/alternator bracket. It just broke the head off of the bolt leaving most of the thread in the hole.

 

i managed to fix the problem today it was rusted in place and an easy out felt like it was going to snap so i slowly drilled it out using slightly bigger drill bits each time. Then i got it as close as i could but not enough to damage the thread in the block i then ran a tap down it to clear the last bits of the edge of the bolt.

 

its all sorted now and all bolted up and nipped up fine so im chuffed to bits. Just hope it doesnt happen again lol.

 

 

thanks for all of the advice guys

hope you used copperslip on the new bolt before you put it all back together
