Buy/beg/borrow a set of stud extractors. Do you have a friendly garage or engineering company nearby?
In the meantime soak with Plus-gas, diesel or similar. Good luck.

I thought this thread was about me for a moment!! Barry,you will needed to soak the bolts. (Plus-Gas or WD40 plus gas is better though ) for at least 48hrs before attempting to remove the bolt. If the break is just below the bolt head, best method is to remove the thermo housing in sections by hacksawing it to pieces, leaving the long stubs of the bolt sticking up, then heat them up with a plumbers blowtorch and remove with 2 pairs of molegrips. Prevent it happening again by liberal use of Coppaslip on the bolts and threads. Think hard about using easi-outs. In my experience they can break off, if the bolt has sheared. Then you have the problem of removing the easi-out As for getting the studs out, use a suitable centre puch to make the point to drill. Try not to damage the original thread. It might help to find out the size/thread of the bolts. Once you get the hole to its tapping size, you can re cut the thread with a tap using first cut and plug taps, which will remove all the rest of the old bolt, and clean the threads out. The only way to stop this happening is to loosen then tighten up the bolts every now and again, to keep them moving. When re assembling the stat, use loads of copper slip grease, and change, or at least remove and replace the stat and housing every 10k miles or so. This will stop it seizing up again! or has SD said get it to a local garage etc.

Yes its a a common problem - I am always bothered that this will happen and even with Copaslip it still can - Glen's advice is sound but do not use TOO much heat as it will melt the alloy and do not force stud extractors if you have to mresort to these as they often will break off leaving a bigger problem than you started with.
Let us know how you get on

Barry it would be worth changing what you can to Stainless I know it's a bit more expensive but I have done all my engine including the long water pump ones because when I took the engine down there were a lot! of stuck bolts good luck

Funny how this subject has come up as I intend to replace my water pump in the laid up months. I will invest in some plus gas and the s/s bolts are a good idea too. I bet I still shear one though

You want to hope its not one of the long ones, which Plusgas will not reach, even the short ones are a pain

Tried to loosen the pump bolt that also holds the alternator adjuster. No go. I think that ones going to shear though I'll start dousing it in Plus-gas as a pump change is going to be on the cards, I can feel a little movement in it. Got the fan belt tight without it.

Update.......... Sent my dad out today to get some nice new drill bits and a new tap, £10 lighter i was set to slove my problem. I got a target thing for the father in law which helped find the centre of the stud and the fun began Well i started was a small bit which went fine then changed to the bigger drill bit and that went fine, and funny to say even tapping a new thred was fine in shock something had gone my way and i couldn't believe how easy it was thew whole job only took 45 minutes and it means the car will be back together in time for the rally on sunday Now for lots of cleaning and building the rest of the car up
