...bleeding, BUT, you can help get out trapped air by raising the front on jackstands and running the engine at a medium RPM, say 2000-2500. Release the cap a few times while doing this, but watch for coolant running out. The thermostat must be open (temp gauge centered) to accomplish this.

... it this strange or what? I recently changed my coolant and since then it seems like something may be wrong. When I grab the lower rad. hose after runing the engine it is cool to the touch...... very much unlike the other hoses. Is there something going wrong with the thermostat or do I have an air lock going on???
The car runs and drives fine... and the temp gauge reads steady just a tick or two below DC
Maybe someone can shed some light on this.
thanks, Chris
