Is that the one that controls the fan to come on and off? if so i had that replaced under warranty within the first two years that i owned the car. I had taken it in for them to check leaking coolant and the temp gauge going to the high side. The tech had told me it was a thermistor. Is that what this part is called? It hasn't given me any problems since. The one thing i have done since i had that climbing temp gauge problem is always glance at the temp gauge and also check on a daily basis the coolant level.
