When i'm stuck into traffic or the car is on idle for several minutes, the needle from tend to go to the red zone. When i'm driving, everything's normal. The thermostat is fine, rad as well.

The thing is with the auxiliary fan. The second fan is not getting on. The fuse always burned.

I think maybe it's a problem with the switch.

Help me guys, thanks in advance.

Check the clutch fan, it could be a likely cause.

Having your AUX fan working would also stop the car from overheating if it does build up.

I have the same problem. The clutch on the fan mounted to the water pump went bad. Got another for $80 and called it a day. I live in Washington, DC so I see alot of traffic so spending 80 bucks on a fan was a wise investment.

Thanks guys! I think also this is something with the clutch/fan. I'll get this checked, since the car is under warranty.
