Just replace both cooling sensors on my 05. Did it myself, bought parts at olympus, hardest part was the one in front at bottom of radiator, a bit of a messy job, about 1 gallon of antifreeze came out, measured the dump out and replaced with new antifreeze. Belly pan has to come off.
The one on the top back of engine came right out with no antifreeze leakage.
Get a step ladder and a thick blanket to lay on. You need to get way up there for that one.
Parts cost me about $50 total.
took me about two hours.
