2008 Chevy Impala Coolant system
My car had ran hot so to the point it looks
like my radiator cap seal is on radiator when
I took cap off. There was a part with a spring
in the neck of the radiator the last time I
checked an now its gone was that possibly
the thermostat or are there a part that is
housed in the neck? Could my thermostat
broke an ended up in the neck below the
radiator cap
