I am hoping for a little help to save me extra driving. I am working on the lower intake and upgrading to the new fuel injector on my jimmy but its about 45 minutes away or I would measure. I forget to measure while I was out there the other day, but I do want all new hose clamps, preferably the constant pressure clip style.
Could someone tell me what diameter clamps I need for the upper and lower radiator, all ends of the heater core and bypass hoses?
Much appreciated.

 

What year?

 

My apologies, I thought I have my signature set here. 2000 Jimmy SLT 4.3 4WD AT

 

If it will still be of use, I can go out and measure them tomorrow for you.

 

Yes please.

 

Upper and lower radiator hoses: OD ~ 1 3/4"
Heater Hoses: OD ~ 1"
Bypass hose: OD ~ 1"

Although I have a non-OEM type radiator, these are OEM type radiator hoses.
Hope this helps.

Thank you that is perfect. This will get me into the ball park of where the clamps range will work,.

 

You are very welcome!

Now I have the information too! :-)

Oh, and there is this tool that I recently found in my box of odd-ball tools that I remember being super useful for the lower radiator hose but could be useful on some of the others in tight spaces. I'm pretty sure this picture below is of the one I have. But even if it isn't, you get the idea. There are several to choose from that do the same job.
