Far left and yellow? Looks like a courthouse? That'd be a low coolant indicator. The sensor is inside the coolant reservoir. Keep an eye out for steady coolant loss as that's a common sign of a blown head gasket.

Yea exactly. It looks like a courthouse.
So what I sould do its change the sensor right?
Thanks for replying.

Ummm... check the coolant level? Check it when the car is cold, before the rad purges into it.

Ol I just is and right now is empty. But I check the. Radiator and I still have coolant.
Hey about sensor where exactly is at because I just check the reservoir and the only thing I see was a small filter.

top off your rad.. fill the overflow to the "full line"

The Rad is not the highest point in the cooling system. Just because it looks full when you open the cap it doesn't mean the system is completely full. Do as Green says and then check the level and add more if needed after you've driven a couple times... it'll take the air a couple drives at operating temps to fully evacuate.

Ol thats cool I'll do that.
And about sensor where exactly can i find it, because I check the reservoir and the the only thing I see is the siphon filter.

The sensor is at the very bottom of the reservoir. If you look at the outside, you should see a connector with a couple of wires leading to the bottom of the tank. That is your sensor
