as i was undoing the coolant bridge unioin bolts the left one snapped/twisted of, the head span off with the threaded part of the bolt still in the block :o :o :o
1. can someone please send me a bolt asap to arrive for tomorrow, i will pay vauxhall said friday cos after 3pm
2. how do i get the threaded part of bolt out? im not mechanically trained in any way i am a lowley electrician please help anyone
-
had this happen to me, how much is left of the bolt?
I jammed something like a coin or thin metal bar across the bolt and managed to rotate it out.
-
mine aint coming lose i think its rotted in? :'( :'( :'(
-
had same problem with mine >:( before, need buy new oil cooler afrer
-
Think I have a spare, and If so should be able to post tomorrow
It's happened to me in the past too. Hence why this time, I have ordered all new ones, for my next rebuild ;D
-
i cant get it out? the cooler bridge left hand side? what do i do???

Can you get some long nosed pliers on any part of the snapped bolt, or carefully tap it around with something?
-
ive tried tapping it round but its not having it. it is really wedged in, will not come loose :'( :'( :'(
i dnt know what to do i am really losing my sense of humor and am getting quite stressed :o :( >:(

Can you confirm if there is anything to "get hold of" or has it snapped flush?
Also.... Heat might help.....
-
yes there about 10mm to get to get hold of.
by heat do you mean like a blow torch?

Can you get some mole grips on it?
-
not enough room to maneuver
-
please someone the more im trying to free it the more any purchase sides are wearing away :'(
-
is there any way you could give it a smack with a hammer?, as this can often break the corrosion holding it & then mole grip it out ;)
-
I would spray penetrating oil(not wd40) on it and leave for an hour or so,then tap the top of it with a hammer sharply to try to crack the corrosion,then try turning it.
-
can you get in to drill it if so put a a small hole down the center say 10mm and try a screwthread extactor

i hope this is of some use :)
-
If all else fails, get a small hacksaw blade and run a cut down the centre of the bolt. Dont go to far.
It might slightly damage the head threads but, this wont matter.
This should remove the tension and allow you to remvoe it (you can always do a second cut opposite to make it easier)
When you re-fit, put a smear of sealent on the threads.

just tried the hammer banger trick to no avail >:( :'(
what is this penertrating oil, what brand and where from? :-?
thanx

wd 40 is similar but may be not as affective
-
ok thanx, i think ill try the hacksaw route as that seems to be a definate answer or should i get plusgas aswell? how much is plusgas? :-?
-

Roughly the same price as WD40 shite ;)

not everyone carries plusgas as stock in the home but more do of wd even if it is less effective still worth trying ::) ::)
-
good point rich i think i spray with the wd and leave it over night i have really lost my sense of humour with this now :-[ :'( :-/
thanx :y
-
WD40 is not a good penetrating fluid (in fact its shite!).....petrol mixed with oil is better....in fact most things are better!
-
good point rich i think i spray with the wd and leave it over night i have really lost my sense of humour with this now :-[ :'( :-/
thanx :y
If ts seized like you say then I doubt a penetrant will do much....WD40 will certainly do nothing
-
do you have access to a mig welder?
-
no access to mig welder? what would one do with such a thing? :-? :-? :-?
-
good point rich i think i spray with the wd and leave it over night i have really lost my sense of humour with this now :-[ :'( :-/
thanx :y
That and a pair of molegrips would be my first choice...
Good luck with it, that sort of thing is a pain... :(
:y
-

Weld a piece of steel across what you have left sticking out. Heat helps to release the renants of the union & gives you something to get hold of with your grips/spanner etc.
-
ah where once i was blind now i can see! i use the mig welder to weld the miggy ;D :y
-
A trick I have used in the past on snapped banjo bolts on hydraulic systems, is to find an allen key which is slightly larger across the diagonal of the hexagon than the inside diameter of the snapped bolt and tap it in with a hammer.
You can then try to work it backwards and forwards gently after applying some good penetrating oil.
You may be able to get a replacement bolt tomorrow from a hydraulic hose specialist, I THINK it is a 3/8 BSP Banjo bolt, although it could be a metric equivalent. take your other one along to match it up.
-
thanx bentvalve i just might give that a go ;) :y :y
-
ok leaving it too soak in wd to try n loosen it hasnt worked.
i banged a 10mm allen key down the centre or the bolt and promptley broke a 11mm socket trying to turn the allen key.
i am unable to fit a standard size hacksaw blade down the centre of the bolt and trying to use a junior blade is a joke, and as stated in previous post again i am losing my sense of humour with this!!!
please someone help :'( :'( :'(
-
Anyone got any idea if a nut splitter will help...
Possibly will help get the bit out by splitting and distorting it...???
Then use pliers to pull/twist it out...
:question
-
I have been following this thread with interest, seeing what others have recommended.
However, one thing that no one has yet mentioned is a trick I have unfortunately had to use in the past. That is cut the stud / bolt flush and drill it out using a bit that is smaller than the diameter of the stud, and maybe drilling pilot holes in sequence. Takes some effort and patience, yes, but does, if careful, extracts the bolt cleanly.
It may of course be necessary to re-tap the hole.
Just an idea amongst many it seems, and assuming there is not enough room for a stud extractor to be used.! ::) ;) ;)
-
Stud extractor is not a good idea (coz there shite, hard and seem to always snap!), the allen key method is a little iffy as the hollow bolt walls are thin and both these methods will force the walls of the bolt tighter against the head.
As said, its a saw job.....

But Mark is there any problem in drilling out as I suggest, and as I have had to do in the past? ;)
-
I think we're all at crossed purposes here.
What I believe kingplym has sheared is something similar to this .....
(https://www.caterhamparts.co.uk/images/77165.JPG)
ie the hollow bolt that bolts down the 'banjo' end of the coolant hose. i could of course be wrong .... again.

If that is the case, drilling out would be even easier to do than on a solid bolt. ;) ;)
-
that is the type of bolt but mine has 4 holes at the top of the neck. i think im just gona have to keep trying with the junior blade, with which i cannot get any purchase and feels like im pissing against the preverbial wind :-/

How about a 3 square (triangular profile) file? Might take a little longer but will be a bit easier to use.
-
you really need to beg,borrow or befriend somebody with a mig plant mate!! :)
-
i have managed to make one cut from the inside of the bolt to the thread. still no joy. but i stopped as i reached the thread, or do i carry on. i started to make a second cut but all the little muscles in me little hand are hurting. >:(
still im slowley getting me humour back ::)

I totally agree with you Lizzie, if it is hollow then it could not be easier to drill out. The only thing I would add is drill slightly under size and the knock out the remaing bit with drift, and have a vacuum cleaner held very close to the bit when drilling to collect as much swark as possible.

I think I would agree with Lizzy. You are an electrician do you have a welder/machinist friend and or a plumber friend? The welder should have penetrating oil you could borrow a squirt or two from and if not the plumber may have it as well as a small portable flame.
I would use the penetrating oil give it its time and then get an extracter and drill bit as mentioned above. Drill it out set up the extcracor then heat the block with the flame. Once it is nice and toasty start to back it out. If it wont give you really have no choice but to progressively drill the sucker out as Lizzy describes. It takes some patience and a steady hand but you can move past the problem with confidence knowing you can rethread if you make small error. Your machinist friend could even help you with that or a helicoil to repair the threads if you really bugger it up.
Good luck Double O F!!! :) :y

Thanks Mike, I thought I was going to be ignored due to maybe my stupid suggestion! ;D ;D ;) ;) :y
Yes I did state that a smaller diameter bit should be used, with pilot holes in sequence before, and this way the bolt is destroyed from within. As you say you can knock the remains out, but I have found in the past that the final bit action often takes out the remains, especially if you put the drill in reverse. ;)
EDIT: Thanks Bbacon as well; we are obviously both on the same wave length! :D :D ;)
-
unfortunately i dont know any machinists or any plumbers. so it looks like i will go with your idea lizzy, but seing as someone broke into my van and stole my drill just before i was laid off means im going to hav to wait til a friend gets home from work.
thanx everyone :y :y :y

Hope all goes well finally Kingplym, and I would strongly advise using a drill with graduated speed capability so you are in full control of the drilling process. Also use quality high speed bits;) ;) ;)

sorry liz but mark dtm won. :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'(
i finished the second cut i had already started and with a lot of blasphamy and tears it finally came out :'( :'( :'(
im so happy :'( :'( :'( :D :y
thank you everyone for advice etc :y :y :y

Lol.....yes it does work.
Easy enough on a hollow bolt.
Been there to many times, particularly on shite ford pushrod engines where teh ploody spark plugs rust into the head (I have even had to replace the head on occasion!)
-
as i was undoing the coolant bridge unioin bolts the left one snapped/twisted of, the head span off with the threaded part of the bolt still in the block :o :o :o
Did exactly the same thing, but with the oil pipe to oil cooler bolt. Luckily, for me, the rest of the bolt came out ok.
How you getting on with the cooler change kingplym? What did you use to undo the oil cooler pipes above the oil filter - i'm having problems. Starting to get a bit cheesed of myself now, specially when I can see the oil cooler staring at me beneath only the oil pipes.... :-X
-
19mm crows foot spanner....
-
yes like mark dtm said 19mm crowfoot. it is hard but stick with it im waiting ti start my engine at 4pm
i might post if it actually works or not :P
-
why are you waiting untill 4 pm for?
-
i was waiting til 4pm for the sealant to cure over 24 hours.
for everyone who is interested the engine started and no water leaked out, but.............
oil ws leaking out the bottom of the engine! :o :o :o
i stripped the engine back down again and my worst fear was confirmed :-/ :-/ :-/
i had snapped another union bolt :-/ :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'(
this time one of the union bolts that went in the top of the new cooler, happily it just came right out ;) no unneccessary sawing or taping this time.
im so happy ;D :'( ;D :'( ;D :'( ;D :'( ;D :'( :y :y :y
-
when i did my oil cooler approx 2 years ago i used "instant gasket" i fitted it, filled it with coolant and drove away.still going, perhaps i got lucky :y ;D
-
i was told to use speciffical vauxhall sealant and wait 24 hours. if id done it like yours i proberely have and fitted a replacement unoin by now :'(
any one wanna drive all the way down to me and lend me a union??? :P
ok i suppose i just have to wait til mon :'( :'( :'(
:y :y :y

Bad luck...It's so frustrating when you have to keep running about and waiting for parts and tools to come, when the actual job seems so straight forward - with the helpful advice from this forum, that is. Hope you get sorted mate. :y
-
tell me about it i could nt believe it :o :o :o but at least my work actually worked!!! 8-) i shouldve bought all new union bolts when that first one snapped but you live and learn.
hey big o bob while you got your plenumn off clean your breathers!!! i wasnt going to do it but am so glad i did! :o abosoultly all my breathers were blocked or on the verga of becoming totally blocked i couldnt believe how dirty it was :o my car must have been the equivolent of an astmatic ;D
there is a how to in the maintenance section, you just clean the plastic box on top of the plenumn and the pipes coming out of this and were they so to, and also the throttle housing
aparantly if you dont so this according to the maintenance section you will blow your rocker gaskets again and again :-[
good luck :y :y :y
