OK: Uncle. I have no idea what you guys are talking about.

However, PS coolers are free simply because of D.3.b: "Oil cooler(s) may be added or substituted." Power steering is part of the engine. Power steering fluid is a hydraulic oil. It needs to be cooled.

Thus, power steering fluid radiators are free. Always have been.

GA, whose NX2000 came with a PS cooler from the factory; well, if you consider a steel tube that passes left then right across the front of the car a "cooler". SE-Rs actually have finned coolers stock...
