Temperature rising fast
So my 03 with 22k miles has been doing this for some time now, when I'm moving at a slow pace under 15-20 or at a stop light the temperature rises pretty aggressively. It never gets to the red but it seems odd to me that even if I'm stopped for 30 seconds it raises so much. The fan kicks in and the temp drops and everything is all fine and dandy but I remember when I first got it around 3k miles I could idle at a light for a good duration and it would barely move. I'm riding in 60-70 degree weather so nothing too crazy. I'm thinking maybe the thermostat isn't working probably, any thoughts or ideas?
