We show you how to remove broken exhaust manifold bolts the easy way. Using a couple of our GM LS heads, we quickly find one of the heads with two broken exhaust manifold bolts. This is not uncommon on these heads and many others as well. Typically, these bolts also break below the surface which means it's impossible to just use vice grips. Using our welder, we quickly weld a nut onto the broken stud and easily remove it.

You did a nice job sir, slow and steady. I see a lot of people making the mistake of using an impact on and just snapping the bolts right off.

@Shoptoolreviews 2 года назад

Thank you very much and thanks for watching.

@BKeys-ke1fc 10 месяцев назад

Yip. I used an impact. Why I’m here.

@ozarkarky 2 года назад

Any way that works is the right way. 🙌

@jimsalaki588 7 месяцев назад

Worked perfectly. Rocking the nut after the weld is key. Thank you

Glad it helped. Thanks for watching.

@Kings.Handyman23 Год назад

That was an excellent educational video, you are, my friend, a true professional in your field! Keep up the good work and I hope it goes as easy as you made it look!! Not likely tho......lol!!!

@wyliecoyote1 Год назад

A person can buy an economical welder to have to perform this repair, a cheap one is all you need. Also, very good to have covered holes over. You can see welding BBs on the tape where it may have found its way into engine if doing engine repair in the vehicle. Overall great video.

@mrerndt Год назад

When I have to do this I always put antiseize on the new bolts!

@Kings.Handyman23 Год назад

Absolutely correct! 💯

Nice job brother. Got some I gotta remove tomorrow. God bless you.

what is the setting on the wire feed welder. Thanks.

@Camo-Dan 10 месяцев назад

I used an impact and snapped it off twice on my 2008 ford escape. I also blasted it all at once instead of welding incrementally. Great video im going to try it this way. Luckily i have a quarter inch knub sticking out to work with. Im using my new harbor freight unlimited 200 mig welder on 110.

@Shoptoolreviews 10 месяцев назад

That should work great, with the nub. Let us know how it goes.

@shainexxxsescrimshaw7605 Год назад

That's great, all I need now is a welder for mine 😢

@chrisjohnson8375 7 месяцев назад

Weld the washer to the tack weld on the broken stud before welding the nut on. Gives you a better bite on the stud

@rodpotts2666 2 года назад

I knew you were going to Ace that. Everyone has taken the shortcut before.

@colts205 3 месяца назад

This might be a stupid question but of the stud is broken 3/8 in can i still weld without worrying about threads? If the build up from the weld touches the thread does it mess it up?

@crazyobservations3080 10 месяцев назад

Sometimes you don't have choice, someone else already broke the bolts. But when your wanting to remove a exhaust manifold never take a wrench to it. Cut the heads off the bolts remove manifold and then start working the left over bolt out. heat, quench, wiggle over and over until they come free. I have never seen anyone able to wrench the bolts out without breaking at least one bolt.

@kevinarmstrong864 3 месяца назад

Good video I started heating the remaining bolt heads to red hot then remove carefully like you did 90 ish% the bolt comes out without breaking used to cut them off then deal with the stud. The dip stick tube is a nother problem to remove heating the block around the tube base then carefully twist it back and forth you may have to heat it a couple of times to remove .I replaced the dipstick tube when I do the job hopefully this helps someone else doing this job 😊

@WASDxMerceless 2 года назад

There's no wrong way to do it. If you got it out, it's the right way.

@darellhands1602 Год назад

I've seen guys remove the welded nut while still hot to make removal even easier.

@alltorque415 8 месяцев назад

what setting did you have your welder?

@Gooditalian 2 года назад

Good job! What happened to the Chevy truck rebuild?

@MrSupernova111 2 года назад

Pretty cool! Thanks!

@laurentmathivet1214 Год назад

Nice video but I wouldn't weld with nitrile gloves on 😅

@donfu2795 2 месяца назад

Hi Tim, I am about to do this on my vortec heads. What are your welder settings?

@Shoptoolreviews 2 месяца назад

I run it pretty hot when I'm doing this. I want to make sure I'm melting/welding the stud that is inside. Probably 125 Amps.

@bismarkbizmark5639 Месяц назад

I don't understand why this procedure does not end up welding the bolt to the head itself

@boosted2.4_sky 2 года назад

Hells yeah TJ!!! LET'S GO!!🏁

@scottloutner5253 Год назад

PB blast as soon as its loose. Not before welding. Then ease it out with oil😊

@hughiemaceachern5282 17 дней назад

I normally get them like this but today nope drilling now

@adamtarran 2 года назад

That has to be so f*#$ing satisfying

@Shoptoolreviews 2 года назад

It really is. Thanks for watching.

@johnnyhotrod 11 месяцев назад

Tried this on my Ram 1500,only got one out of four out so far. I’m not getting any play in loosening them,they’re really stuck.Heat and penetrant didn’t help. I’ll keep at it

@markwohlgemuth2775 10 месяцев назад

Spray them a few times with PB let it sit overnight then weld the nuts on the next day

Yes

To all those that complained; I tried to complain at the broken studs and not a single one came out.
