Accidently broke off a nut thread

It’s a homemade nut driver, much easier to avoid over-torquing, and very compact. .

 

You use the hand to tight it? what purpose the tape serves? i might need one of these.

 

Yeah just hand tool.

The tape (hockey stick tape) is grippy and it’s bulk gives you more torque strength.

You can buy similar socket drivers; basically look like a screw driver. But they cost and they’re bulkier. If you’ve got spare ratchet extensions it’s something to try.

for trivial locator bolts/screws this works just about right.

 

Ohh i see, i will try to do one of these in the future. Thank you very much.

 

All good advice, here is mine. Be very careful here. Use some solvent to soak into the threads, if you have a few days to do this even better. Take your time, if it even feels like the stud is going to break again stop. Having the stud break flush with the casting is not good, it can still be repaired but you may want to have it towed to a shop at that point. I have fought with stuck, overtightened and rusty hardware for a long time and several times had to punt and pay a professional to fix it. Now I have a MAP torch and a bottle of ATF, many times I do the heat/juice thing a couple times before even trying. Still bugger a bolt once in a while but not nearly as often.

 

Here's my torque limiting device. Works with pretty much any ratchet.

 

wrong tool for the job, using 1/2" click type torque wrench for bolts like these is way overkill and prone to errors since they are by default in ft lbs, there's a 1/4" click type torque wrench that is calibrated only for inch lbs. Heating it with a MAP torch will easily loosen that with vise grips or 2 nuts on top of each other could loosen this without using MAP torch.

 

SOLVED!

I broke that bolt too - and replaced it with the guidance of a professional mechanic. It wasn't difficult but i cried & panicked before learning to fix it.

Here's what we did:

1. Removed air intake box to have more space & easy access to broken stud. (Box is held on by three 10mm bolts)
Also, unplugged air sensor so box wasn't tethered in our way by it's wiring.

2. Used small 5 inch vice grips to grab the broken stud & It backed out easily without any torch/heating - it's not reverse threaded. Just spun counter clockwise.
No need for OEM part from Stealership.

3. Purchased 56 cent replacement bolt of dimensions: "6mm course thread" at True value hardware store.

The Store was nice and Cut the bolt to similar length as original. Cut end was slightly jagged and smoothed out with less than 5 strokes using a file.

4. Screwed new stud into place & attached thermostat housing in a gentle manner without breaking it.

The above took about 1 hour of labor so... happy face... Turning bolt slowly out with those vice grips was tedious... 1/4 rotation at a time in cramped quarters.

5. Took pictures but this website says files are too large to upload. NOOOO. PANIC! TEARS. WHY GOD? NOOOO!

How do I remedy that? I want these pictures up lol.

This is my first post.

Thank you and
BEST REGARDS

Yep, I agree 100%! I use the doctors hypocritic oath when working on vehicles, "Do no harm!" Even changing out spark plugs, there's SO many ways to make a simple job a nightmare! I've heard from all my friends who work on Toyota's that those plastic ignition coil connectors are notorious for breaking (the clip), especially in older cars with covers that hold in the heat so I'm very anal, and slow, about gently lifting up the tab, instead of squeezing the other end. to get them off. (And I've, yet, to break one....knock on wood.) But I have a bag of new ones just in case. (My 2014 Tundra is overdue for new plugs as soon as it gets warm.)

 

The coil connectors usually break on Toyotas with a V6 engine. The plastic bakes (esp under the intake plenum) and they just crumble.

I keep a bag of replacements on hand as well.
