Aux. Coolant Pump - 4.2
Anyone know where the Aux. coolant pump is located on the 4.2? ( I am assuming it has one) I know the 2.7 is located under the intake... but I can't find any info on the 4.2's....

Re: Aux. Coolant Pump - 4.2
My '99 passat 2.8 AHA has it. You can run the heat for 20 min. after shutting off the engine. How is it that a passat has this feature but the top A6 with cold weather and premium package does not?!? The 4.2 would be a good candidate for saving fuel. If it truly does not have one, any idea's on how to put one in?
Maybe a pump off a 2.7, and a series of solenoids ( If ignition = off & blower = on & Outside temp =< 15 celcius)
maybe not the last one... might be a little difficult with $3 relays.
If anyone has a practical approach to this I'd love to hear it.

A stock 2.7T car with only a chip is over 300HP.
Current 2.7T at 380HP and 410 ft-lbs Torque with a heluva low end spool kick... with room to grow by adding more fueling. I've driven a few 300HP 4.2's and they are great but I'll take my 2.7T with cake any day!
Go for it 
I'd love an RS6. I've been looking for one but a good RS6 is pretty rare... still looking.
