Open the fill cap when the engine is cold and has not yet run to check if coolant is up to the proper level in the expansion tank. Put the cap back on and make sure it is tight.
Do not remove the fill cap when the engine is running as the system is pressurized. Open The bleed screw, right next to the fill cap, should be open only enough so that coolant comes out and leave it open until only coolant comes out. Do not remove the bleed screw.
