While changing my thermostat I have managed to snap 2 of the bolts that hold the housing on

They have snaped clean off and there is nothing at all that I can grip.


It is a CVH

any ideas?

 

Drill'em out and re-tap i'm afraid.

Unless anyone else has any ideas??

 

u can get a stud remover im sure? cant mind how it works tho.....

 

eazy out (sp) just dont snap that or your fooked!!

 

just leave it and call the customer and say its all done

 

i think its on hes own car

 

and

 

LOL, On one bolt the car louses all its water in 5 secs

Should I just put the car in the garrage and leave it until next show session?

What do you gugs think of this

As I have also stuffed the thread!

 

You have to take the old one's out before you can helicoil it mate.

 

can I not just drill the bolt out?

 

I wouldnt drill it out as you risj damaging the thread. Buy some left hand threaded easy outs. I bought a set of them and they're awesome. Cheap to, I think a set was less than a tenner.

 

Yes you can but i'd try & take the old one's out propperly first mate. Summat simillar happened to me once & i had to score the end of the remainder of the bolts just enough to unscrew them out with a screwdriver. It took ages but i got it done

 

the thread is allredy damaged, but where can I get some left hand threded easy outs?

 

machinemart? any tool supplier should do them

 

or ebay

 

just wich there was some person I could phone that would come out and sort it out for me lol

 

Where about are you mate?

 

Newbury, Berkshire

Not really much around me

 

lol! I would have come round & helped out but im abit out the way form you............................................... ..B'HAM to be exact! pmsl

 

Weld a nut into the stud if it's not too deep.

 

if the thread is already damaged it sounds like you have made a right hash of this one and you are going to risk snapping the easy out trying to get the sheard bolt passed the damaged thread..... good luck..ur going to need it....

 

Who are you calling a gug!!!!!!!

 

If theres enough thread showing, why not use the 2 nut trick???

Scew on 2 nuts tight, then use the first nut you put on to get the sheard thread out.

it won't move as the top nut dont let it....................

But you've probalby tried that thinking about...

 

Mate drill small hole in centre of the snapped bolts then use these to get it out

Then use these to re-tap thread

Matt.

 

easy out will be the best option,drill a small hole in the centre of the snapped stud so the easy out has got something to bite into,if you aint got a set pm me your address and i will post you my set and you can return them when you have finished.should only cost £1 to post.

this is now the problem



it has snapped clean off at the surface of the head!

The bolt at the top seams to work

The one on the side just spins

All the bolts don't go right through to the head, and there is lots of room, so it should be do-able in situe.

How do you get a M8 bolt out? seams a bit small to drill?

 

with a small drill bit........

snap that though and you are as they say BOLLOXED...........

 

if you're going to get some easy-outs then make sure you spend just a little bit more and get a decent set (i.e snap-on), you dont want it snapping on you!
