2006 Nissan 350Z bought used with a lot of after market upgrades already in the car. Having a lot of fun doing a water pump replacement myself.
I'm attaching a picture of our screw together Radiator Hose Clamp... which I can't seem to find anywhere on the internet.
What I'd like to know is what it's called (to help improve my ability to search for it)... and what type of tool would you use to loosen it.
Might even want/need to buy one in the future. I do like how it looks but don't love some scratches on it.
Ultimately I wrapped both halves in a rubber strip then used channel lock pliers on both halves to unscrew them... and this ultimately worked (on the radiator end), but they are clearly made with specific indents to allow for a tool to grip and turn them.
I can imagine it is some type of wide mouth half circle wrench head with 4 "teeth" that match up to the indents so you can slide it into the notches on the clamp, take a twist, slide it off and do it again... (probably manual, can't image any kind of ratchet for this situation).
Assume I'll need two of this tool to hold the outer half still while I screw the hose side half into it to tighten down on the hose (clamping it back to the radiator).
I'd much prefer to use the real tool and not scratch the finish each time I go to remove or put them back on the radiator. Looks like prior mechanics also lacked the tool as the Radiator side of this clamp is pretty scratched up.

Thanks in advance for any tips, leads, names, or info!

Would like to know the name of the shiny (not red) two piece screw together radiator hose clamp and what kind of tool fits this particular type of clamp.

 

Still searching the internet... figured out I need a pair of spanner wrenches. Cool.
Still can't find the hose clamp (not its name).
Have searched for: Radiator Collar, Radiator Crown Nut and many other things I could think of... nothing like this available that I can find.
Anyone seen these? Or know of a car parts manufacturer that makes them?

 

They are python clamps and I believe discontinued.

 

Awesome tip, thanks! Found them as Python and Pi-thon... but only in super old posts and references... so I fear you're right, completely discontinued and not available for sale as new from any manufacturer. Guess I'll try and monitor used markets... kind of a bummer, they look nicer than most clamps imho.

 

I believe Ztoys sold them or made them? IDK been a while I do know I got him to sell me caps that were "discontinued" so if you find a way to get ahold of him maybe you can convince him to make a batch.

even with the right tools you still have to use a layer of plastic or tape to keep from putting nicks and scratches on them
