#163 of 172 Best Replacement Clutch??

Aug 19, 2012 (4:44 am)
I JUST bought a 2007 Hyundai Tiburon gs 2.0 - with only 42k mile.......I am going to talk to my mechanic about removing the Clutch Delay Valve. I have only had the car 6 weeks..... Don't wanna know how mad I am it's beginning to slip.
I am glad I found this forum! I have had other manual transmissions, and at first I thought I was doing something wrong. My other car is a Grand Prix (<3 I love that car) so I just thought it was maybe going down in engine size...... maybe I am just giving it too much gas???? It did it on a couple hills at first, then it did it on a straight away ....... Hellllll No! Now I know it's not me. I talked to the dealer and am going to call the manager on Monday to talk to him. Yes, I did purchase the extended warranty, of course the clutch is not covered. Oh, and I guess Hyundai only gives their NEW cars a 1yr 12k mile warranty on their clutches. Hummmmmmmmm Wonder Why?? Anyways I have been reading the post and jemtec, thank you for all the info!!!!!!!! I have a question, if I do have to end up replacing the clutch, Flywheel, etc... I do NOT want to put another Hyundai Clutch in there. I have heard good and bad things about some clutches. Valeo and Sachs seem to be recommended a lot. . . . . .
Any Ideas??? Hopefully I can get the Clutch Delay Valve removed soon and it fixes it, at least delays the wear. It doesn't do it all the time, and there is no clutch burning smell.......... keeping fingers crossed. Has anybody had any transmission problems from removing the Valve? Why did they put it there? Thanks for the Help!!!!!!!

Hey there.
Honestly, the stock hyundai clutch isnt bad at all really.
If you are looking to juice up your tib, then a stronger clutch isnt a bad idea however. (adding another 100-200 Hp).
Almost any aftermarket, performance clutch is excellent.
You will have to replace the flywheel due to its unique, dual mass layout, and the fact it more than likely has hot spots on it, possibly some mild cracking as well.
Hard to say because things are unique for each situation.
Removing the clutch slave delay valve alone adds tens of thousands of miles to the stock clutch and brings out real "feeling" at the pedal.
Ive got over 100K on my stocker, but I removed it very early in the cars life so things are still going great.
As far as the transmission having issues, Ive have heard of people being rough with the stock layout, and having the clutch disc and pressure plate basically disintegrating.
Sometimes, things are in the wrong place at the wrong time, and things like a bent transmission input shaft (which can ruin the input shaft bearing) can happen as well as the fingers on the pressure plate getting bent, causing all kinds of binding and well..a bad experience.
Im glad to see you are looking to do this work correctly.
I can say though, that the stock clutch is totally fine provided you dump that silly clutch delay valve.
From then on you can expect many years of trouble free driving.
Speaking from real experience.
Best of luck man!

Thank You!
Yeah, I am going to talk to my mechanic about the CDV this weekend.
So do you think removing the valve will add to wear on the transmission with normal driving?
I think I will just find a reasonable clutch and flywheel if I have to replace it, not concerned about soupin' up the Hyundai.
One day when I can afford a Camaro I will look into that!! hahaha
I am loving the gas mileage on this thing!!!!
Hopefully it will last for a while at least with the mod. - gotta do somethin'.
Thanks again for your input!!!
Take Care!

Nah.. it will do the exact opposite.
In fact, the feel will remind you of every other clutch made in existance that doesn't use a delay valve!
It will not harm the transmission in any way, and of course, it will allow the clutch to wear normally.
Ive driven my Tib a little hard from time to time, and the only thing I get out of things since the removal of the CDV is positive clutch take up. (no slip) and quick response.
Additionally, less slipping also means slightly better Mpg.
The difference is AMAZING!
The CDV was an attempt to make clutch newbies learn faster (the extra slip means less stalling) at the cost of serious wear however.
I would like to personally yell at the engineer that thought that using a delay valve in the clutch slave was a good idea!?
Im guessing he drove automatics!
LOL
Yes, the mileage on the Tib is quite good, and the 2.0 Is a GREAT engine.
(I also own a 2005 Elantra with the same great engine, but an automatic)
Just be sure to change the timing belt, idler and tensioner (can buy in a kit) at the recommended intervals! Its an expensive fix if you snap a timing belt and its actually not too difficult to replace.
I always get low 30s in the Tib when I drive it reasonably.
Having a clutch that works right makes the car a BLAST to drive!
Oh.. one last note.. when you remove the clutch slave delay valve, you will remove the little spring it comes with.
The valve has a small hole in it, and 4 square cut outs.. (i believe) and it is cylindrical in shape, and the spring goes up inside it partly.
Discard both of these parts, put it back together and bleed the system.
Good luck!

I have a 2008 Tibby and,after reading all your messages regarding the clutch slave cylinder, I wonder if by removing it, will my clutch problem be resolved. I bought the car new. It Now has has 65k miles on her. As I let the clutch out in first gear she shutters. With a little more gas, I can usually enjoy a smooth release. The problem is only related to first gear and been going on for the last 5k miles. Should I remove the valve and spring or replace the entire clutch and remove the valve and spring? Thanks for sharing all your knowledge.

Honestly, It sounds like you already are in need of a new clutch.
The "shuddering" you are experiencing is called "clutch judder" and it is caused by a warped flywheel and likely the pressure plate as well.
What it is, to be more specific, is high spots created when the metal of the flywheel has warped into a new position by heat of a slipping clutch.
This position creates a not so smooth surface for the clutch friction disc to be sandwiched between the pressure plate and flywheel.
The flywheel is often cracking as well, and that speeds up the process.
In my honest opinion, I would replace the whole thing.
The flywheel, friction disc, pressure plate, throwout bearing and the pilot bearing.
Absolutely get that clutch slave delay valve removed ASAP!
Anytime is a good time!
I wish I could give you a more positive answer, that would save you money now, but it sounds like your clutch is already done sadly.
If at all possible, get it done as soon as you can and avoid driving it if it all possible until you are ready to repair it.
If you get a nuclear clutch (as I like to call it) it could really damage things, including the transmission itself if you keep driving on it!
OEM (Original Equipment Manufacturer) is actually pretty good stuff, so if you aren't needing a racing clutch for any extra power you might add to the car, Id go stock, or buy a good quality OEM style replacement from say, Oreilly's or Autozone.. Etc.
As far as for the Flywheel, Im not sure if there are any aftermarket companies making them. (although they should be by now honestly) so there might not be alot of alternatives.
If there are, shop around.
You could also save some money buying a kit online!
Good lucK!

Thanks again for your valuable opinion. I found a replacement kit with flywheel on EBay: F1 HD PREMIUM CLUTCH KIT + CHROMOLY FLYWHEEL fits 03-08 HYUNDAI TIBURON 2.7 L SE GT for $298.11. Since I've never replaced this clutch before, is the a good purchase? According to many posts on this forum, i wanted to be sure I found a steel flywheel.

You might check with some forums on people who have used the kit you are mentioning, and maybe do some additional comparisons with other kits, and see if anyone has had any bad results, etc.
I dont think going with a chrome moly flywheel is a bad idea honestly, however, one thing to note, is once that Clutch Slave Delay Valve is removed, you will be experiencing much less slipping, so there will be considerably less heat and wear on every clutch part.
Unless you are banging your gears hard, nearly daily, or are lightly/heavily modified, I really don't think stock is all that bad and might be considered.
The $300.00 price you are mentioning is pretty low.. almost inexpensive really (considering it is a complete kit with a flywheel) but I really don't know much about the manufacturer, so you might do some more research before plunking the cash down, and me getting all nervous you might get an inferior product.
Sometimes, the Ebay stuff has some pretty crappy chinese items that are so cheap, its crazy, but some are actually not bad at all.
Also, keep note of shipping because that low cost kit could be way more spendy once they include a really high shipping fee (due to the weight) and that could end up being more or at about the same price as something nearby where you live, and you could just go buy it that way.
Just stuff to consider there.
Good luck dude.
#171 of 172 08 Tiburon clutch at 65k mi

Clutch went out at 65k miles...really!
#*+. (Never will I again purchase another Hyundai). Was told it would cost $1800 to $2200 to replace. Found a Valeo/Bahnhof clutch kit with flywheel on EBay for $300. Wow, right. Found an SAE mechanic on Craigslist to install it for $280. Less than $600 I have a new clutch that is far smoother than its crappy predecessor. If you are considering Hyundai, think twice. They use inferior parts. You may be saying to yourself, "But they have a 5 year/100k mile warranty". Tell that to the other people on this site complaining about the same thing. Spare yourself the frustration of being told you don't know how to drive a clutch, just buy a Honda or Toyota. I know you will not regret it. Hopefully Hyundai will.

Sucks you are having trouble.
You arent the only one, but I will say this.
Once I took out the clutch slave delay valve, early in my tibbys life, the clutch has 110K on it now, with ZERO issues.
The quality of the clutch is usually decent, although there are times you might get a defective part(s) from time to time.
The clutch is not made in house by hyundai.
They are sourced out by an outside supplier like most car companies do on a regular basis.
In many cases, alot of parts in todays cars are not made in house, and the clutch might be sourced by the same people who make them for Toyota or Honda.
No joke.
It is typically, cheaper to get parts from companies that are already tooled up to make the said parts.
The warranty is actually great with Hyundai (I have had some little things replaced under warranty), but the clutch, brakes, wipers and other wear items are not covered for a reason.
There are alot of differences in how people drive the cars.
But, for me, the clutch delay valve is really a execution flaw, not a design flaw.
The engineers had to know it wasnt a great idea to make a clutch slip more than it should, and expect them to last with that kind of slipping.
Clutches wear when slip occurs (and it wears slowly over time in a normal clutch with no delay valve) everytime you shift gears and is totally normal.
However..
It is totally unneeded to try and appeal to newbie clutch drivers that wanted the lower cost of a manual transmission, and expected automatic smooth driving from it!
Thats why it is an "execution" problem.. not a design flaw perse.
I love my tibby and being someone who has one, it truly isnt a quality issue in 9 out of 10 cases.
I also dont exactly drive like a grandma, but I can say.. taking the clutch slave delay out was the smartest thing I ever have done in my car and will prevent future clutch failures if you get it out early enough, or when you have to replace a clutch prematurely.
Best of Luck
