I have a 95 Honda Accord. Whenever we let it idle or drive for a while
afterward there is a boiling sound from the radiator overflow tank. At
first we thought it was just low so we filled it to the max and then
let it suck up whatever it needed and then refilled it. Now, it seems
to be at an adequate level but it's still boiling. The weird thing is
that the temperature gauge in the dash doesn't seem to register the
heat. It doesn't seem to be moving at all. We just had a friend
replace the thermostat like we thought the problem was from
originally, but that didn't seem to do the trick. Does anyone know
what the problem could be?
