97 astro van, when driving I would have to rev the motor to get the temp to drop, after a day or so that didnt work, so I replaced the water pump, thermastat, and radeator. The temp gauge doesnt drop when im driving, only drops to about 210 when in idle. My heater only blows cold air, none of the positions on the switches work to control when the cold air goes. High speed doesnt work. I have flused the 50/50 mix about a dozen or two times. I have also found some sord of pressure line that isnt connected to anything. Not sure where that goes? The water is not circulating in any of the hoses causing major build up of pressure. I have no idea please help me.
