I saw the same thing discussed recently on one of those half-hour automobile repair television shows.

They suggested holding a flashlight or worklight behind the radiator and looking to see how much light shined through to the front, because over time, road debris can accumulate between the radiator fins (and any other fluid cooling coils/fins in that area - like trans cooling coils, a/c condensor coils, etc) which can restrict air flow and significantly reduce cooling capacities.

And seeing as how the VX front end is just a straight shot right into the grill, it's not hard to imagine how a lot of road debris could find it's way into our radiators. Sometimes if we're lucky, it's checking the simple stuff that pays off.
