It is obvious you have a leak and the engine is overheating. If you do not see coolant on the pavement or an apparent leak anywhere, that is a bad sign. Smell the exhaust and if it smells sweet or you see white smoke at the tailpipe, you have a blown head gasket. Do not ignore this as it can cause serious engine damage. Check the oil level and if over full or milky looking, you for sure have serious problems. Another sign is bubbles coming from the radiator with the cap off cold engine just after startup and running. Have this looked into ASAP before you ruin this engine.
