overheating spider

[rpmoreno]

The temp gauge usually sat just over the 180 degree mark, but today, I noted it to go beyond the mark between 180 and 260 degrees. When I turned off the car yesterday, there was an odd clicking sound of a relay located on the side wall in the engine bay, just forward of the passenger side. I tried swapping leads with an adjacent identical relay and the sounds were made there too. Please help!
