RE: {Chrysler 300} Radiator Hose Corbin Clamp tool?

["'Bob Jasinski' via Chrysler 300 Club International" <chrysler-300-club-international@xxxxxxxxxxxxxxxx>]

I like the original look Corbin clamps provide on vintage cars, and must admit that I cringe a bit when I see screw clamps at a car show on a restored engine (unless they came that way). My experience is when properly applied, they work well and don't leak.  The clamp must be the right size, and in good condition.  Old hoses that have taken a "set" where the clamp attaches can be a leak point, and/or hoses that have dirt/scale on the inside and are not cleaned can lead to a leak. Also, when installing the clamp, put it on the hose back from the attachment point, then slide the hose over the nipple.  There will be a raised part on the nipple (don't know what it is called), but it will show as a bulge through the hose.  I bring the clamp up and right past the bulge so it presses on the bulge as well as the nipple.  A good Corbin clamp tool allows that precise placement, especially in tight locations.  By the way, my local Ace hardware carries Corbin clamps.  My 2 cents worth.

related , I found that kits of  “ corbin clamps “ from china are not heat treated correctly to spring temper and easily take a set , losing the clamp force . they usually look cad plated ( yellow/ brown )
real ones are dark grey or green / black in my experience . 
the off shore  ones are sad joke , leak , hose blows  off too 

One thing that greatly improves appearance of screw band types is to cut off the piece sticking out 
A 6” or bigger pair of dykes will notch the band at existing slot sides , then bend  back and forth 3-4 bends,  it breaks right off . position nut under . SS has poor fatigue resistance .

By the way they get loose over time unlike real corbin clamps, check each spring

>> See the attached picture, the one with the red handle works well in the situation you describe.  It has the number 427 on it, I believe it is KD brand.  It lets you move the clamp into position while it holds the clamp under tension.  I use it more than the traditional l type I also have pictured.

>> I’m replacing the hoses on the F and I’m using the Corbin style self adjusting single wire clamps ‘ala the original style. I’m having a devil of a time with the lower radiator hose clamps. I have a set of single wire hose clamp pliers that I’ve had for probably 50 years but I’m not getting the leverage I need to fully open the lower clamps to move them into the correct position, particularly on the water pump. I see that there’s a Gearwrench Vermont pliers product that has a ratchet feature (which my current pliers do not have and which would make the job far easier.) I also see a plethora of products that have a ratcheting handle that runs to a remote set of jaws at the end of a cable that would seem to make it easier to get to the hose/clamp position on the underside of the water pump.
