Power steering hose clamp, how to tighten?

Tomorrow I'm going to flush and replace my power steering reservoir, but I cannot figure out how to tighten this new clamp. Probably it's really simple, but could somebody please tell me how to tighten this thing?

They look like Oetiker clamps, which I know how to tighten, but here I don't know where to crimp them.


Ps: sorry for the double post in the DIY section, I wanna change it tomorrow, and there i did not get a lot of replies.

I would use hose clamps instead of that that can be found at any autoparts store or home depot.

Correct. That's a crimped hose clamp, one time use only.

Need special pair of CV boot clamp pliers.

Here is a very cheap version; http://www.amazon.com/Lisle-30800-Bo...=pd_sbs_auto_3

they might. Around the bulge at 7 o'clock in the clamp pic. That's assuming the bulge at 9 o'clock is pressed together and won't just open up on you. I'm not a big fan of that clamp, like others have said I'd put on a gear clamp and call it a day.

Hmm, actually the one at 7 o'clock separates from the ring, this is what confuses me. Shame they didn't give me those other clamps at the dealer.

You need to squeeze the neck of the Oetiker clamp like this with the kinpex pliers. A ceramic tile nipper works too.



[Edit] This is wrong way. I was doing for a used clamp where the looped part is pulled apart from the first install.
See post #19 for the right way.

Thanks for the picture! But how exactly does this tighten them? As both points already touch each other.

Neck should not be touching when pre-installed on the hose.
If it is touching, you can not use it obviously.
That's why it is one time use only even though I reused a few times for low pressure applications. You may bend to make a larger loop for that neck area in a pinch.

That clamp takes a special tool to crimp it. If you can get a regular hose clamp that is tightened with a 7mm or 8mm (the smaller one is better here) driver, then you are home free. You need either a regular hose clamp or a special tool.

Having said that, I replaced a power steering hose on my daughter's '00 323, and I don't remember that there was a hose clamp at all. I forget lots of stuff though...

Ah! The new ones I have look exactly like the picture. So first I need to bend the neck, put them on the hose and tighten?

Oetiker clamp is the way to go. It provides the even 360 prifessional compression, prevents leaks

I bet it will spread out once pre-installed on to the hose.

I think the clamp location is not what was shown. Squeeze the clamp in this pic to make it tight...

OR, you can use a clamp that has a screw to make it tight.
