Put a socket on the bolt with a long flexy bar resting on the ground at the front and just blip the starter.

Yup-That's as good a way as any to shear the bolt off.

A better way is to engage 5th or 6th gear - handbrake on and use a breaker bar with a hexagon socket to undo the bolt.

Probably less risky but if its that tight it could cause the clutch to slip, had it myself.

Had a Fiesta in once,

it had already been to the main dealers for an unsuccesful atempt to get the crank bolt out,

Oh and the owner called me to say they wanted 2 hours labour for trying and failing???

Guess what I told her?

anyway with that in mind I tried everything up to and including the big breaker bar and triggering the starter.

Zip.

I ended up drilling the head/shank off,

which initself took around 70min's,

And the new gates belt kit came whith a new crank bolt?

Hmm,

Clearly they knew what I didn't.

Once you'd drilled the bolt, how did you get the remains out to fit the new bolt? Easy-outs and then clean threads with a tap? Sounds like a PITA of a job.

Once you've broken the torque by removing the head it should come out easily

Drilling out the bolt was an absolute sod,

Started small diameter and drilled in stages up to what was about 1/2 mm from the measured shank on the new bolt to a depth of just under the flange.

once that was done the pressure was off the flange and a half inch chisel on the flange was enough to break what little torque was still on the fastner remains.

It actually came out with just fingers!

No damage to thread or crank pully.

Hardest part was getting a pilot hole dead center.

This was 4/5 years ago and the car still comes back each year for the MOT.

Only way to get access to change the well overdue cam belt.

I doubt it would have survived this long on the old nasty belt I found on it,

But I hope to never have to do it again.
