Glad you found the leak, it looks like this part.
DORMAN 800413 {Click Info Link for Alternate/OEM Part Numbers} Cooling Quick Connector
That is a white looking part, the other/black one is 2mm longer, and says Heater Hose Connector. The one leaking in your pic is labeled Cooling Quick Connector.

Is there two parts you found leaking? I did not notice two pics of a leak, if that white part in your pic is the only leaking part, then that is all you need.

As for that clamp on the rad hose, worm gear clams are not the best to sue IMO, they have high pressure points, which is where the screw is, they can cause the hose to split and leak, and on occasion if used on a radiator inlet/outlet that is plastic, it can break them, causing you to need a new radiator.
The clamps you see on the other hoses, they are constant tension clamps, and they are much better to use.
You should be ok as it is now, but if you ever have another leak look there first, and if the hose does ever leak get a constant tension clamp.

As far as the clamp you mention from my pic of the reservoir tank I should basically change that to constant tension clamp if so I used that on the hose that connects to the thermostat. It seems to imprint the hose I don't like how it looks.

The black one next to it is DORMAN 800414, the only difference I can see is that the black one lists as 2mm'* longer than the white one, which may not seem like much, but to be safer than sorry I'd use the same color part to replace each part.

In post #8 of your posts in this thread I see the coolant reservoir with a constant tension clamp already on it, unless you changed it to a type you need to use a screwdriver on that one is fine.

As for the worm gear clamp on the radiator hose, if it is on there well, and there is no leaking then it should be fine to leave it for the time being, but looking at the hose, from what I can see in the pic it looks like it is getting a bit worn out, but it should hold out for a while.
I'd consider changing the coolant hoses the next time you have the antifreeze serviced, then you can let them know you want the worm gear clamp replaced with a constant tension clamp.
TIP: Whenever the same hose is reused, make sure the clamp fits right back over the same indented part of the old hose, or leaks are possible.
It is better to just replace them when getting new hoses, but it is not always necessary, I'd rather be safe than sorry though myself.

Thanks for the tips and which parts to use I will be getting that fix soon also my mechanic said he will charge me 75 to do it. Is that a good price or is it something I could do. And is there any special tool I need to use

Remove the pieces off your truck and match them up at the store with the new ones.......that'* what I do since there are a few different styles depending on your particular vehicles cooling design.

If you have rear heater controls, then I believe you will need to get the pieces that kinda look 'T' shaped.......if you have no rear heater controls, then I believe you need to get the straight pieces.

If you have rear heater controls, there will also be a rear (second) heater core behind the rear passenger side cargo area panel......the T shaped fitting is what allows hot coolant to flow to/return from that second heater core. If you don't use the T, you will not have any rear heat (but cold a/c will still work).

The pics he took kind of look like T'* to me, the top almost looks plugged though, hard to tell, the pics definitely do not look like the straight pieces.
And looking at the T'* sold, one is white, the other is black, he has both, you can tell that if you look at the pic.
He said both are leaking, which is why I gave him part numbers for both.


As for how hard of a job it is, I don't think it is too hard to do, but I am not sure how long it will take, the parts are quick connect parts, so I cannot see them taking long to replace, you may have to drain a little coolant to keep it from pouring out when you replace them. You can get a quick connect removal tool, but you can remove them without one, not sure it is worth an hours wage, maybe a half hour...

The quick connect tools are easy to get, but you will pay around 14.00 for it.
OTC 6046 Heater Line Quick-Connect Release Tool for GM
All local parts stores should have it, here is a link to see what it looks like, also read some of the comments, helps you understand how to use it, it should be pretty simple.
Amazon.com: OTC 6046 Heater Line Quick-Connect Release Tool for GM: Automotive Amazon.com: OTC 6046 Heater Line Quick-Connect Release Tool for GM: Automotive

"Slide disconnect tool over the heater line. Clamp tool over line. Then press tool into the connector to release. "
