A Little Help Please...

[Jaye R]

HI All

I had a coolant leak - as per this photo...



So I went to remove to look at replacing any gasket that might be there and managed to shear two bolts (they did this with not much persuasion by the way)…





Please can I have some guidance as to how to remove the bolt threads left behind...

Many thanks

Cheers
Jaye

Hi Jaye, if you've never tackled this kind of problem before ( and I guess you haven't or you wouldn't be asking) I seriously consider getting some help
To some one experienced at sorting these kind of problems it's not a big issue but messing with it could make it much worse.
You will get lots of suggestions suggesting applying heat and Welding nuts on etc.

Hi Mike

Sound advice as always...as the task in hand is preventing me from taking the car anywhere to have it looked at, does anyone know of anyone in the Wakefield (West Yorkshire) area who would have the knowhow to come out and help me?

Many thanks

I suspect you'll find that getting it recovered to a local workshop will be cheaper and easier than getting a mobile mechanic to deal with it. This will be much easier to deal with in a workshop.

There are also mobile stud removers
/re threaders. Can’t think of the proper word to call them!

This is just a example but they are down south

A quick google should hopefully bring up someone local to you.

I’ve been given the number for a chap in Manchester that’s worked on my cars before. As in, it’s who my garage call out when they snap one or are repairing something “I’ve had a go with“

I can pm you his number but not sure if he’ll travel to you or be worth it. Do you have a local garage that you use regularly and trust. They will probably know someone equivalent in your area.

[The Big G]

Just been looking and found someone else recommending the chap whose number I have.

He’s known to me as Dave the stud. I don’t want to post details directly but here’s a link to the thread and it’s the last post by little Pete on the 16th July 2016.

Hope this helps you and/or someone else in the future.

Hi Jaye,

You have my sympathies - I've been there on this one

There's a thread here

I took the bonnet off and radiator out to get the access,

Then it was just a case of a fine drill (which inevitably snaps) then a few happy hours (gently) with a pointed needle file to create a hole in the centre. Then a bit of drill and retap.

If someone with my limited ability can do it - I'm sure you can.

Only problem is I ended up doing a lot of chassis refinishing and a new set of silicone hoses while I was on with it..

Good luck

[Jaye R]

Hi all

Thanks for all your responses...i'm going to look in to getting some help locally. If I have no joy on that front I will just have to 'focus my inner patience' and go down the drill, re-tap route

In the meantime the penetrating oil is being liberally sprayed...

Cheers
Jaye

Hi Ray...just read through your thread again...where did you end up sourcing a new gasket from? The O ring looks okay on mine...but there was no sign of any gasket left when the housing came off...

Cheers

If they have broken off leaving a stub, (as mine did when I was replacing my water pump), there is something simple you can try before throwing money at it.
A liberal dose of proper penetrating oil (not WD40) over a couple of days. tap the end of the stub with a hammer to shock it and then wiggle it back and forth with some small mole grips until it starts to turn. .
It worked for me and I was surprised how little force it needed to turn it once the tension is off.
But be careful not to destroy the stub as if this doesn't work the stub makes more serious methods easier.

As RayTVR comments. it can be sorted by a novice

Hardest part is drilling close to center and drilling straight

The worst scenario is what happened recently when drilling out a sheared clutch to flywheel bolt, drilled it central but drill didn't go through straight, thought "no worries easy-out will now remove it", bought new set of easy outs, easy-out snapped off, drilled out easy-out (it was softer than the sheared bolt), drilled out bigger straightening hole up as drill went through by applying a sideways pressure on drill, drilled out bigger again and tapped new thread

Make sure to use a decent easy-out

Although rushing a job is not the way forward, was rushing and cursing what had gone wrong, slowly slowly does it

[phillpot]

Drill it wonky, snap an Easy Out off and then pay someone four times ad much to sort out your mess 🤣

Seriously sh#t easy out if you can drill it!

[phillpot]

There should not be a gasket, the O ring seals it.

Hi Mike

So that would suggest....as it was leaking from the bottom of the housing...that the O ring is knackered and I need a new thermostat (which come complete with O ring)...correct?

If so, please can you point me in the direction of one

Cheers
Jaye

[RayTVR]

Hi Jaye.

As Phillpot says - no gasket just an O-ring which did come with the thermostat; I did use a thin smear of blue gasket paste as well.

Thermostat was from a well known auction site - described as;

CTH316K 2742 CONTINENTAL THERMOSTAT KIT FOR FORD GRANADA 2.9I 2/1991-3/1995

Hi All

Well with the 'patience' head on and all your kind advice to hand I am please to say I have success

Opted for the drill out to 5mm & then 6mm tapping of new thread approach...

New threaded holes...



And all working again with no leaks



Many thanks again for all the advice

Cheers
Jaye

And he didn't bks it up with an easy out. Terrible things.
Gives one a sense of satisfaction when you complete something like this.

A bloody tricky job done well .
