Hey everyone, I have had a 2006 NBC for a couple of days with no problems. Now I have this blue temp light on when I first start up, but then it goes out after 15 minutes or so. There is also a loud roaring sound coming from the motor that slowly goes away as the car gets warmer and the light goes out. Any help on this would be greatly appreciated.

 

hey there,
according to my manual, the blue light indicates that your engine is still cold and so you should not push the engine too hard or travel at fast speeds yet...when the engine warms up it goes away (a good thing).

if it flashes or it turns red, you have problems. Check your manual for more info!
