How can we tell if ours came with the new fan or the old? Our 2008 never overheats, but the 2010 automatic we tried, hit five bars in minutes.
The difference is obvious if you take the tupperware off and look at it. The original fan does not have the shroud that covers the entire back-side of the radiator. Most riders have not experienced major overheating issues, it seems to be mostly those that live in hotter environments or those that do a lot of low speed driving in traffic or around town. There have been a few exceptions, but most are in the previously mentioned groups or a combination of both.
