I've compiled a list of part numbers for the constant tension hose clamps for our TJ / LJ cooling system over the last couple of years. Due to various reasons, my Jeep now has worm gear clamps on it and at this time of year when the temps get cooler, I start getting leaks at the ends of some hoses, requiring a little tightening of the clamps. I'm going to be overhauling my cooling system sometime soon, so I thought I'd post up these part numbers and some links. Thanks to
@Jerry Bransford for providing a link to
Clips and Fasteners on a similar thread on another website.
When I bought my '06 in 2016, this is what it had on the hoses (the number stamped into one of the end tabs). I plan to put these same sizes back on. I don't know if these are exactly the ones put on at the factory, but it's what was on mine.
42 on upper radiator inlet
47 on thermostat housing
55 on water pump
47 on lower radiator outlet
24 (both ends) on the smaller heater hose
27 (both ends) on the bigger heater hose
I ordered these from

Jerry provided a link for the clamp stamped 42. They come in a box of 5.

This site has the 24 and 27 clamps for the heater hoses as well as the 42 and 50 sizes, but they are in boxes of 10.

Another option for the heater core hose clamps are to order these hoses from Amazon. Both of mine came with the hose clamps already on the hoses.

There was a MOPAR part number of 52005580 for the 42 clamp. I ordered one and it appears it has be replaced with 55037990AA and had 50 stamped on the tab. There were two per package.
