Check to see if the T-stat is plastic or aluminum. It is common to swap the t-stat when you do the pump and the updated design is plastic vs the originals aluminum. If you have an 06 and your t-stat is plastic someone must have swapped it already. See this thread for more detail:

the 9th pic is the t-stat shown in the original aluminum material. The 20th pic shows the updated plastic design.
