The low coolant light has been on again lately. Was fine for a few months after the new rad. and cleaning the sensor. I checked the rad. and it's been full. No leaks anywhere. I fired it up tonight with the cap off so I could wait for it to heat up and open the thermostat. About 3 min. in at idle it started to puke coolant out the rad. I pulled the RPM's up some and it belched a few times. Got to the point where I couldn't raise the RPM's much more to keep it from puking coolant so I stuck the cap back on it.
Before I shut it down I noticed I had heat in the cabin but the top hose was stone cold still. Temp gauge didn't hardly move. This is a new rad., thermostat and coolant. Water pump is newer as well. Is this a sign that the system is plugged up somewhere? Never had an issue like this one.
