Default Broke off stud on water pump -help!

I was tightening the water pump bolts when one of the lower studs broke off. Any suggestions to make sure it won't leak?

You going to need to replace the stud.

Year of car and engine type-4 or 6 cylinder?

Picture?

How much of the stud is sticking out of the water pump housing after removing the pump?

Any access to an arc welder?

After removing the pump, is enough of the stud exposed to grab it with a removal tool? Or cut a slot in the end of the stud for a screw driver?

Before doing anything. Review the various YouTube videos on broken stud removal. The issue is the assumed limited work space is going to make using the typical stud removing methods much more challenging. Best to know what your going to do rather the risk making the situation the worse in using a hit or miss method.

Default Water pump problem

  1. It’s the v6 model and it’s the lower stud that a bolt fits over - very little access and I was thinking of just putting some oermatex on the gasket and hope the other fasteners do the trick - what do you think about that?

Might try something like JB Weld. Something that can withstand the coolant system pressure without being pushed out where they may now be a gap due to the lack of stud.

You are own your own here as everyone replaces the stud.

Default Broke stud

After reviewing many sources, I agree with you about the stud needing replaced - how difficult are those studs to turn out? Just trying to gauge how optimistic I should be

The odds of removal are 100% but a stud can be easy or challenging to remove.

Broken bolts/studs are common, as is a broken stud in this engine or the 4-cylinder. The result being there are hosts of internet threads and videos on removing studs/bolts. Suggest you read as much as you can on this issue.

Might start by removing the pump and if the engine is equipped the water pump housing. This will allow access to any portion of the stud that still extends out from the block.

If enough stud is exposed there are tools to try to extract it. If you have access to an arc welder, a nut can be welded to the stud.

There are some threads at this site on broken thermostat housing studs.

With a combination of heat, penetrating oil and an extraction tool I was able to remove. Thanx for all your help bro!
