Been reading conflicting information on if the HD tow is good enough to cool. I have also read that there are many different coolers offered on the 3rd gen expedition anything from a 11, 7, and 5 plate setup. Mine has 8 plates that looks to have 6-7 actual usable plates at ~23" long so it looks like I have the "updated" HD trans cooler.

My wonder is how well the standard system cools the engine and transmission in high heat/humidity that I typically haul in. Should I be concerned? Should I look into aftermarket coolers? or am I good enough with the "updated" HD setup?
