I have an 02 WRX and I have noticed lately that the OEM Temp Gauge has been going up, little by little. I checked the coolant level and it is good...but, Now it reads "HOT" all the time. In the morning, it goes to hot as soon as I start the cold motor.
I checked the connection behinde the speedo cluster...all is good. Anyone have any suggestions? Is there a sensor I should check?
Thanks in advance
