Yes, they are supposed to have coolant. They are connected to a temp sensor diaphragm attached to throttle body. If my memory serves me correctly, you can replace them by only having to remove the throttle body assembly on top of them, the hose pieces are somewhat short. Air plenum has to be disconnected of course along with the cable.
