I noticed on my monroney sticker it says "heavy-duty engine cooling" under the 5.7 hemi option. I haven't seen this written on many other window stickers, If your truck has it do you know what the difference is on a truck with the heavy duty engine cooling vs a truck without it?

I know on the last gen trucks that usually came with a tow prep package AFAIK and I believe HD cooling has a different cooling fan and clutch, a different auto trans cooler and a PS oil cooler.
