2001 BMW 325i E46 leaking Radiator reservoir fix replacement

It all started when I notice a puddle of coolant in the garage where the car is parked. After looking closer, I can see the leak is coming from the bottom of the reservoir. I decided to video the removal process. The original intent was to document how things were taken appart so I will remember how to put them all back together. Upon doing the work, I decided to share my work and now so here it is. A bit rough but does show how I did it step by step.

This video shows how I replaced my radiator reservoir or also known as "coolant expansion overflow tank" on the 2001 BMW 325i. There may be other way to properly remove and replace but this is how I did it. I used only OEM BMW part as I have had bad experiences with other brands.
