Snapped a stud while putting new coolant pump on. halp?

eurogarbage · Tue, Jul-06-2010, 01:31:42 AM

As the title says, I broke off one of the studs that the coolant pump is torqued down too.

Referring to the picture: I over tightened the top right nut, #3, and snapped off the stud.

Wtf I do?

A few options here....and 1 of them is not reinstall the pump with 3 studs. Don't even think about it.

Is there any stud exposed from the block? If so, if you don't have a welder, tap it lightly with a hammer and spray some penetrant on it. After a few minutes clamp on it with a pair of vice grips as tight as possible and get it out that way.

If you have a torch, heat it up with that and do the same minus penetrant.

If you have a welder, weld something to the remaining stud that will give you better leverage and turn it off like that....

You may have to drill out the remaining stud and re-tap and get a new stud in worse case scenario...

10Nm is no joke

Yea, mixing up Nm and Ft. lbs is no good either. Admittedly, Ive done that a few times myself......

Yeah, been talking with my dad about getting some new torque wrenches. Guess I should have acted earlier.

in any event, OP, what this guy posted are some good options

Very easy to do...is any part of the bolt exposed? If so it is simple to get it out with a pair of vise grips...other wise you could try one of those screw removers...worse case is already covered!

If none of WRXEATRs ideas work, buy a set of easy-outs or reverse drill bits.
The stud should'nt be corroded, so it should come out pretty easy.

be VERY careful here...

Can't get the part till Friday-Saturday

. So here is the question: car has almost 81k miles, should I replace the radiator while I am at it too?
