How to change engine clutch actuator fluid?

Hey guys, I'm trying to learn how to maintain my vehicle on my own.

It's a 2017 hyundai ioniq hybrid.

I'm having trouble figuring out how to replace engine clutch actuator fluid.

Anyone can point me in the right direction here?

This is the 'classification' it says in the owner's manual FMVSS116 DOT3.

Thank you

1st thing some of you others are going to think, is that this a a manual car. It is NOT. So the traditional methods of bleeding manual clutches may not apply here....

It is a "dual clutch" automatic.

For those that don't know, the Hyundai Ioniq is Hyundai's answer to the Prius. I don't know much about them; I've never even sat in one. Powertrain is different from other cars. It's automatic transmission, yet still have a clutch--only I think it is driven by the computer--which I *assume* requires a scantool to properly bleed.

In other words, it is electrohydraulic, which may mean that the electronic master cylinder needs to be manipulated to properly bleed.

If none of this makes sense, just go to a shop.

A few months ago, I test drove a little Smart Fortwo. I wasn't planning to buy it; I was just curious to see how it drove. They said that it has an "automated manual transmission"........which, from what I gathered, is basically a manual transmission with the shifting done automatically. I don't know how that differs from an automatic transmission. Is this the same kind of thing?

so its manual transmission on a hybrid ? first for me .
you have to raise the car possible to take a few items apart the starter might have to be removed the exhaust system ?
the part looks like this .https://www.amazon.com/Dorman-CS37498-Clutch-Slave-Cylinder/dp/B001PYG8FQ/ref=asc_df_B001PYG8FQ/?tag=hyprod-20&linkCode=df0&hvadid=375249767987&hvpos=1o1&hvnetw=g&hvrand=8050328894831753834&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9016909&hvtargid=pla-804771447971&psc=1&tag=&ref=&adgrpid=79352187760&hvpone=&hvptwo=&hvadid=375249767987&hvpos=1o1&hvnetw=g&hvrand=8050328894831753834&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9016909&hvtargid=pla-804771447971
loosen that bleeder . prey to your god whoever that is that the bleeder does not break!!!! very fragile . .
open the bleeder pull the cap off where you fill prey to your god again you do not let it go dry or its a real son of a B to bleed these systems !!! again who told you to change this ? i would not change it...
it should and will be changed when you replace your clutch . all those parts come in a kit .
if your a hot dogger and insist on changing it to be a HERO .
my advice get a straw so on something to suck the fluid out where you put it in. refill it . go into the car pump the clutch repeat to its clean .
again there is zero reason to change this fluid ever it should last as long asthe clutch . fluid will last 20 years dot3
DO NOT PUMP THE CLUTCH WITH A DRY RESERVOIR ! done correctly you wasted 5 bucks on fluid . done incorrectly you bust a bleeder and spend 600 on labor and 200 on parts

I've never been in one either, nor do I really work on hybrids that much. You are probably the only one who has talked remotely about hybrid work

Electronics have really ****ed up a lot of otherwise simple switches. In fact just a few days ago I tried to change brake pads on a ford. After hours of trying to shove the piston back on the caliper, basically what's was 3 of them at the same time, I finally came to the conclusion only fords computer could do it. Ended up costing the guy $800 to change BRAKE PADS only.

I am not sure dual clutch transmissions are a good idea to own yet, if longevity is a priority... Like CVT transmissions they may have a high failure rate.

Sometimes, old tech like boring slush-box automatics are more reliable.

Ford example... I haven't look into others. I usually deal with old cars.
Ford couldnt get it right to save their lives !

Hyundai has a 100,000 mile warranty at least !
