Once you checked those, then move onto the fan relay.
Only 1 fan will kick on at around 220F.
The 2nd fan will kick on only with the A/C on at 245F

The engines are designed to run hot for emissions purposes.
Awesome thank you!! Are both of these sensors something that is fairly easy to pull out from the top side of the engine? I don't have very much space to work on the car, no flat area to get the car jacked up to get to it from the underside. I have a temp sensor sender that I bought a while back to change and never got to it. I hope they are easy to get to from the top side of the engine.
