Pink over spray 2010 Lexus RX 350

Car Model: 2010 Lexus RX 350 Submitted on January 8, 2019


I have noticed a pink over spray on the engine cover and am not sure where it is coming from, or why it is there. I am assuming it has something to do with my cooling system. I noticed what looks like a sensor in the shape of a spark plug with wires running out of it, would this be where i am getting the over spray?
