Hello

 

1993 L reg Cooper SPI

 

Thermostat housing with the sandwich plate

 

3 bolts securing it all 

 

1 bolt has sheared off in the block

 

I tried to get it out using a left-handed thread bolt removal tool, but failed miserably

 

I've now mostly drilled the bolt out

 

I have lost a few drill bits in the process

 

I have a tap set

 

Any advice regarding tap size, the need for a different bolt or even a different approach completely?

 

Is it a stupid idea to consider epoxy / GB weld securing a stud into the hole instead of trying to a cut a new thread?
And holding it down onto the stud with a nut & washer, with the two others still as the bolts as they should be?

 

Thanks

A Heli-Coil kit is usually advised to do the job properly, see Cooperman's post in this thread link below:-
