Hello!

I drive an '04 R53, just crossed 121k miles. I finally ordered myself a new coolant tank and am gonna be installing a resistor for the low speed fan as well. Poking around on the site, I'm thinking I should (gulp) replace the supercharger oil.

My question is, should I go through with this stuff all at once while I'm down there, or will I be ok for a while as I am?

​​​​​​Replace supercharger oil
Replace water pump
Replace radiator tubing
Replace thermostat and housing
​​​​​​???

I've already done the o-ring/oil pan gasket replacement, am I missing anything? Thanks so much!
