AC working intermittently and Coolant hose or Radiator Broke

[x5turtle]

Hi All, haven't been on the forum for a while as I have been on my regular maintenance for the X, it's been 10 years and first sign of trouble showed up yesterday.

Living in So Cal, weather as suddently hot yesterday to about 90F, the x Runs fine and then for some reason, AC works intermittently, then I try to drive at higher rpm, it seems to help temporary, and then.... I see smoke coming out of hood and I knew either some radiator hose broke, or the radiator is broken.

I cannot relay the two events as the AC is separate from the engine cooling, but I am thinking if it is possible that the control for coolant for heat in cabin is clogged, which lead to burst of hose. I am going under the hood today to identify where exactly it leak from and planning to do a high milage service at 170K.

My plan is to replace
Fan Clutch,
Fan blade,
water pump,
thermostat,
radiator hose( need advice on how many hose, I replace two hose before, but I heard there is more in the back)
Drive & AC belt,
Put in New coolant, no need to drain :-)

What are your suggestions? I have been working on my X since its off maintenance warranty, and I have replace the pump and thermostat and belts. I have most of the tools to complete the job if required, but just want some brainstorm ideas! Any help or suggestions to links is welcome too! I can post pictures of the repair if any of you are interested if its not on forum already!
