My son has a 1999 monte carlo. It overheats and also heater isnt blowing warm air. The radiator fluid keeps going into the overflow tank and the hoses are hard. A mechanic he called told him to bleed? Some valves maybe he had an airlock. He did that and it was fine for a day then started doing this again. He really doesnt know where to start or what to look at to fix the problem. Could it just need to be flushed or maybe the heater core is bad?
