Brake Fluid Flush:

Interval on this job is every two years. Old fluid absorbs water, lowering its boiling point and increasing its corrosive properties, potentially damaging hydraulic components.

Shop time should be around one hour. Purchasing or building a pressure bleeder (such as Motive Power Bleeder) will cost less, and you will save money every time you use it.

Coolant Flush and Fill:

Another 24 month job. Especially critical if you see GREEN coolant in the tank, which will accelerate degradation of entire cooling system, including rad, pump, block and head. Drain fully using bottom hose (better not to disturb drain plug, which is made of BrittelSheiB and is likely to break), refill with water, idle until hot with heater valve open. Allow to cool, drain again. Repeat as necessary to eliminate the Green Death. Refill with recommended coolant (I use Pentofrost NF).

Power Steering Service:

Probably a three year job. ATF degrades with time and heat cycles, picking up contaminants (rubber and metal) along the way. Also, your handy power steering reservoir includes a FILTER, which is non-serviceable, therefore the res MUST be replaced! Many cars are running around with the factory res, endangering pump and rack. WYAIT, verify that reservoir clamps, and the pump feed line are updated per Porsche TSB.

That is all. GET TO WORK!
