Sourced an Audi Oil Cooler

[mr.utility at highstream.net (David Utley)]

  The boiling temp of water/glycol IIRC is just below 230.  If you are running 
you engine hard, or have high ambient temperatures, the ability of the coolant 
to remove the excess heat from the oil is greatly reduced.  It also depends on 
the mods that may be on the engine in question.  Driving styles can also 
influence the oil temp.  I myself, have a car that only has a switch for a 
throttle, so you can imagine why my oil temp was high...  And just for the 
record, here in Okieland, we can see many days of 100 plus temps...
