Thanks to Efthreeoh for the DIY. I just did all the hoses, radiator and tank on my 06 325i. I am only at 120k miles but my daughter is taking the car to college in AZ so I wanted everything to be new. Water pump and thermostat were changed a few years ago.

The only hoses that were in bad shape were the two that go to the oil filter housing area. Both had good hose but bad plastic on the inside. They fell apart when I tried to pull them out. So if you want to stay on a budget, just do those 2 (I spent close to $600 for everything). Next worse were my heater hoses that were soft under the air box area. The rest were fine as was the radiator and tank. All were 14 years old.

Mine car is an automatic so the parts list is slightly different. When compared to the PDF parts list, there are 2 different hoses and 2 additional hoses.

2 different hoses
17127548223 is replaced with 17127548224. It has an extra hose on the assembly going to the trans oil cooler.
11537535829 is replaced with 11537516414. It has an extra fitting for 17127540020 below.

2 additional hoses.
17117524710 - trans oil cooler - goes between the trans oil cooler and the radiator.
17127540020 - low-temperature cooling module - goes between 11537516414 and the radiator.

And finally, this is the o-ring I used for the temp sensor. BMW does not sell these. https://www.ecstuning.com/b-uro-part...21433077s~uro/
