Engine Fails To Reach Normal Operating Temperature

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify that the cooling system is properly filled. Refer to Cooling System Draining and Filling (Static Fill With HP5)  or Cooling System Draining and Filling (Static Fill Without HP5)  or Cooling System Draining and Filling (GE 47716 Fill With HP5)  or Cooling System Draining and Filling (GE 47716 Fill Without HP5) .
  2. If the complaint is a low temperature reading, check the temperature gage for proper operation. Connect a scan tool to the vehicle and read the system temperature. Compare this reading to the temperature. Replace the gauge or switch if necessary.
  3. Refer to Heating Performance Diagnostic if the complaint is no heat from the HVAC system.
  4. Verify proper thermostat operation. Refer to Thermostat Diagnosis .
