Trying to so a bit of preventative maintenance and wanted to give the intake system a Seafoam treatment at 26k miles.


I just did this treatment on an accent and getting to the throttle body is a breeze but on the sonata it seems to be a little more involved. I can locate where the TB is but the hose clamps around the intake piping don't seem to be the standard 10mm or philips-head bolt. Instead, its some sort of weird rounded head that I am unsure of how to remove.


If anyone has done this before and knows what works on those hose clamps, I'd appreciate the help. Can take some pictures if need be.



Thanks!


Also my first post here.

welcome to the forum

edit: just re-reading your post; you mentioned that the hose clamp bolt isn't actually... a bolt and it's more rounded off. are you able to upload a photo to imgur or something and post a link? does it seem like it "once was" a hex-phillips bolt? lol.. are you the first owner of this car? have you or anyone else tried to take that clamp off? it may be well worth replacing once you get it off if that's not how it's supposed to be. you may be able to use shears to cut it off if you can get some slack in it.... then again there could be something I'm missing completely about hyundai and their hose clamps (shrug)

I think my Gen Coupe came with that kind of head on the clamp. It comes off somehow and is just a regular clamp IIRC.

Here are some of the pictures of the clamps in question.

They had tops to them,, then at certain torque, the top twist off, leaving what you see now.. pop the remnant cap off, and you will find a simple 8mm hex to operate the clamp
