Were is the air release valve/bleeder on the 03 i35? Can anyone post a picture please.

For?

To burp the coolant

There isn't one. That went out with the VG30 engine in 1994.

The closest thing you have to that is the radiator cap. Get the car on an incline or ramps so that the front end is about 12 inches up and run the engine with the radiator cap until the coolant heats up and starts to circulate through the radiator.

At that time, any air in the cooling system should come out.
