Why does my car sound like its steaming?
Why does my car sound like its steaming? Look for any evidence of coolant leaking from the engine, radiator, radiator or heater hoses. If you see steam or smell a sweet odor, it is antifreeze leaking from the cooling system. Do NOT open the radiator or coolant reservoir cap until the engine has cooled down, and do not add coolant until the engine has cooled. Why do I hear a tapping noise at the top of my engine? If the noise you hear is a fast tap or clatter near the top of the engine, it could be valve noise...
