Moreover, what would cause my 2003 Impala to overheat?You could have a bad cylinder head gasket or leaking intake gaskets causing your overheating problem, or it just could have a large air pocket in the cooling system from when you changed the thermostat. Or you could still have a large air pocket in the cooling system from when you changed the thermostat.Secondly, is it bad if my coolant is boiling? If the radiator cap is faulty the valve Can be stuck closed causing too much pressure to build up. When pressure goes up so does the temperature, eventually the coolant will boil. Additionally, why does my car say hot coolant temp? When the temperature light comes on, it indicates that your engine is overheating-running too hot. An engine should not overheat if the cooling system is in good condition; a faulty cooling system triggers the temperature light to come on.What does it mean when your coolant reservoir is boiling?One of the most common causes is a blown head gasket, in which the air pressure inside the cylinder heads is transferred to the cooling system. This escaped air causes bubbling in the coolant/antifreeze reservoir, which can often be mistaken for boiling.
