This often happens when there is air trapped in the system that can't get past the thermostat. You can often solve the problem by bringing the engine up to full operating temperature, thermostat fully open, and squeezing the air bubbles into to overflow bottle from the upper radiator hose. If you don't see or hear any bubbles, you have not been successful.

    My Mazda millennia started running hot and power steering stopped working. Could it be a bad water pump that's making the power steering go? Heat in the car is cold now too.
