Replaced my coolant temp sensor on my 4.6is. The DIY asks you to remove a few things to do it, but I just reached down there and removed it mostly by feel. Took 15 minutes tops with most of the time figuring out how to remove the electrical connection.

Next is the double temperature switch, located on top of the water pump housing. DIY asks to remove several things but I am going to try to do without doing any of that.
