My '08 3.0SI spends 6 months per year in WA state and 6 months in SoCal. It is approaching 70k miles and other than engine oil, brake fluid, and coolant, it has had no other fluids replaced.

The vehicle is completely reliable, and I intend to keep it many years. I do all of my own maintenance, and I am about to replace the water pump, t-stat, and coolant, in advance of any problems. What fluids should I replace before leaving for winter quarters in the Southwest?

Ciao,
Dick
