How To Fix Your Toyota 2.4 L Engine's Stripped Cylinder Head Bolts

[@paulmaxwell8851]

Viewers need to understand: this is not just an annoying coolant leak. This manufacturing defect leads to coolant in the rear cylinder, which destroys the block. My brother-in-law experienced this, and the replacement of his ruined engine cost about $8,000. Toyota knew all about this but instructed its dealers to claim they had never seen such a catastrophic failure before. How do I know? The dealer told us.

Im doing it on a sion tc. The Power steering pump was a pain. Im Waiting on the timesert kit now.

[@brianjuan5822]

I have a question? What kind of drill did you use? I’m using a rigid drill, but it seems to not cut when I’m in a certain position and would get stuck. Would it be my drill not strong enough to keep cutting

[@mikeschmidt4800]

I searched how to check if head bolts are stripped and it brought up the exact engine. An expensive one to repair too!

[@robbiestewart1984]

My rav 4 was diagnosed with this issue last week by the mechanic turns out bolts 1 and 2 had lost all their threads and were just sitting in holes thankfully there was no damage to block because of temporary fix sealant stopping so only needs re-tapping the holes and replacement bolts

[@josetorres28jt]

just a quick question, is it recommended top all the holes? or just the damaged ones ... thanks for your video!!

[@stellarboy1]

Jose Torres only the damaged ones.

[@manuellamas4747]

Awesome video. I’m actually about to do this on a Camry that a customer just brought

[@johngrambo939]

Where is this shop located? I need this work done on my Toyota

[@khaido2301]

According to Toyota tsb the 4 outter holes can’t be drilled and tap if they stripped got replace the block is that true are u can still put incerts and should have no problems

[@davidwell686]

I have this engine in my Highlander and no problems yet so should I just replace those bolts and not worry about it? 110k miles on the car.

[@iknowyourebrokeauto468]

If the engine runs and has no isues leave it alone this is only if you pull out the threads when you torque the head down after a head gasket replacement

[@delallegood5799]

I bought the Huhn kit. It works well.

[@HowtoAutomotive]

Del Allegood not familiar with that kit. I’ll have to check it out. Thank you for watching!

[@delallegood5799]

I should have been more specific. Huhn NS300L.

[@rajdhir919]

Before you put the head gasket back down, do you not have to machine the surface and make sure it’s flat and even?

[@ultinico]

Not always. You should check, but after overhauling a lot of engines I realized it's not that critical to do that. What is critical is torquing the head down correctly.

[@NN-gy7xl]

wow, u don't see videos like this anywhere. thx

[@HowtoAutomotive]

N N thank you!!

[@lalabilloo]

Sir Brain, I have a question . I am working on a 2003 Toyota Camry 2.4l. To start with the hole size is 12MM after drilling it gets bigger 16MM. Is this okay or I have the wrong drill ? Please help me for this. Thx a lot, Lala

[@michaelstoltz58]

The thread size is m11x1.5. Watch the video on Jerrys Broken Tap on You tube. He does a lot of Toyotas. Mines a 2003 too

[@AutosolutionsPNG]

How do I purchase a kit like that (Daniel from Papua New Guinea)

[@stevelinwood4397]

Brian - Great video very informative 👏 I have a slightly different issue though I have a stripped stud thread but the stud will not withdraw from the block it just spins in its hole. We've tried a puller on it but no luck. Any ideas?

[@kyleweiler6604]

Just a quick question how may studs did the kit come with I have to do every one on my block

[@HowtoAutomotive]

kyle weiler there was about 10-12 in the kit. Just be careful when you do this not to let the shavings go down into the engine block.

[@missmackanointed1mack367]

@@HowtoAutomotive Hi HwRu? Is it expensive for the the sleeve for the head bolt?? How much does it cost??

[@yemieddo3820]

Where did you get the kit

[@2koolforyou88]

Quick question its pretty serious can that insert be drilled out because the tool to drive the insert in the new threads a small piece broke and now it won't let the head bolt screw down basically can I restart the process because I have 5 extra inserts

[@HowtoAutomotive]

2koolforyou88 Yeah that’s pretty serious it’s hard to get those out. If you can get the old insert out and re-tap it then you should be OK.

[@2koolforyou88]

@@HowtoAutomotive any tool you would recommend to try and get it out

[@erikchacon6619]

Excellent video.

[@mikeschmidt4800]

How did you figure out they were backing out? I have one with a blown head gasket and I assume it is due to this because that's what this engine does. I want to make sure this is the issue and possibly just do the head gasket repair. Thanks

[@HowtoAutomotive]

For me this vehicle had a blown head gasket but then when I went to torque to head back on the bolts pulled and stripped.

[@fernandozuniga3859]

Is it a good idea to do all the holes or will that cause some issues?

[@HowtoAutomotive]

It’s probably a good idea to do them all. If it pulled one it will a few more

[@fernandozuniga3859]

@@HowtoAutomotive Thank you for the reply.

[@jonsey1886]

@@fernandozuniga3859 Per the Toyota/Scion TSB you skip the outer set of holes on both ends, so just the 6 inner bolt holes. If any of the outer 4 holes are damaged you replace the block.

[@mechanicgamera4230]

What size the drill bit you used ?

[@devinalejandro242]

Are you using the 'BigSerts' because the bolt holes are so deep? I've noticed the regular m11x1.5 says "not for deep bolt holes"? And therefore I'm not sure what to use

[@HowtoAutomotive]

This kit was design for this exact Toyota engine.

[@2koolforyou88]

How would it work if 3 of the bolts are stripped and you are working with one of them and the other you need to use the supplied bolts with the kit to secure the plate down I know its shorter does it only use half the threads not reaching the stripped part?

[@HowtoAutomotive]

2koolforyou88 you could drill out that particular holding slightly larger by hand and with a slightly larger tap and bolt just enough to hold the plate. Do the repair on the bolts in question and then flip the plate around and drill that hole out The one that you Temporary repair to hold the plate.

[@phillipsmith1847]

Good stuff. How do I get Time Sert?

[@ojarquin74]

Awesome, video, instruction, excellent thank you for doing this kind of video I had seen another video but your video by far is better ,best

[@SteveRobReviews]

Nice one. Man I really wouldn't want to do it but it can be done . 👍👍

[@HowtoAutomotive]

STEVE ROB it was very time-consuming I had to do six out of the 10 Bolts

[@SteveRobReviews]

How to Automotive I would have cried LOL

[@gort3969]

What causes the bolts to strip like that?

[@g.b.5206]

Because the tread are in a aluminum block and the screw are steel ( harder martial) this happen when the car overheat the block and materials get softer so do not overheat the engine or it will happen

[@alvarobesnier]

how can you tell you need to fix this issue before is too late

[@stevenlarsen5774]

cost of that tool is crazy. Anyone have the dimensions? I am a machinist and can just make one of those...

[@Integrity.is.everything]

What did you find out?

[@missmackanointed1mack367]

Hi HwRu? Steve. Larsen do u know where to get it??

[@iknowyourebrokeauto468]

Yesh blow out the hole and drill bit right into the intake manifold thats good for it

[@robj7481]

Are the threaded inserts made of steel because I've seen what happens when steel parts and aluminum parts heat at different rates on an engine. IT'S NOT GOOD! Jeep Grand Cherokees notoriously drop valve seats for this reason.

[@susanbaltimore1823]

If youre just losing a little coolant when its fully warmed, many times you can just put longer, fatter bolts in the back side. There's an extra half inch down there. Buy the "2AZFE repair bolts" on eBay. 2.5 hours, cam comes out of the way but you need to have or fashion a long probe to release and hold the tensioner.

[@HowtoAutomotive]

Susan Baltimore hopefully I don't have to do this repair again:)

[@susanbaltimore1823]

I did mine 2 years ago, still perfect.

[@tommiebynum5426]

I have to make this repair. My 03 Camry is at 187k miles. I'm loosing a steady flow of water when the engine is running only. I'm assuming my bolts are very loose. Did you get the cylinder head to a machine shop or just went with the bolts and reassembled. I havn't taken anything apart to see how bad it is. What else did you do besides use the longer fatter bolts.

[@vissevolker955]

Re Ebay bolts. I did that method - I used a ratchet with some oil on the bolt. I didn't even have to take the head off, just moved the cam out of the way by taking the t chain off and hanging it out of the way with a pointed bar in the tensioner. Fixed the leaky head in 2 hours for $35.

[@davidbates6493]

Did you use the bolts sold by treasurector on ebay? Do you have directions on how to use probe to hold tensioner?

[@cmoney1218ify]

Would this work on a broken bolt inside?

[@HowtoAutomotive]

No you’ll need a bolt extractor for that.

[@NA_NA1915]

Or you can use link's of copper from a old tv cable make the same size as the insert 5 or 4

I used to think Toyota's reliable but I just bought a Camry that has this problem and my wife and kids broke down in the middle of the road. Toyota refused to recall this problem so my decision is to never buy a Toyota again.

[@ferndog1461]

Toyota models, built in Japan, are still reliable. The stupid design was corrected by 2007 model year. Yes, Toyotas ran like tanks in the 90's. Hyundai has improved quality, surpassing Nissan, for sure.

It is a crap engine

[@HowtoAutomotive]

Overall it’s a pretty solid engine.. Only see occasional problems.
