Cooling System Filling & Bleeding

    WARNING: DO NOT stand in line with or near engine cooling fan blade while revving engine.
  1. Install front splash shield. Lower vehicle. Fill degas bottle with correct engine coolant mixture. Install pressure relief cap. Move temperature blend selector to full warm position. Start engine and allow it to reach normal operating temperature. Add correct coolant mixture to degas bottle until coolant level is between "COOLANT FILL LEVEL" marks.
  2. Turn ignition off and allow cooling system to cool. Recheck coolant level and fill cooling system to "FULL" mark on degas bottle. Repeat step 1)  until reservoir level is okay. Bleed cooling system by selecting maximum heater temperature and blower motor speed settings. Position control to discharge air from A/C vents in instrument panel. Start engine and allow it to idle. While engine is idling, feel for hot air from A/C vents.
  3. CAUTION: If air discharge remains cool and engine coolant temperature gauge does not move, engine coolant level is low in engine and must be filled. Stop engine, allow it to cool and fill cooling system.
  4. Start engine and allow it to idle until normal operating temperature is reached. Hot air should discharge from A/C vents. Engine coolant temperature gauge should maintain a stabilized reading in the middle of "NORMAL" range and upper radiator hose should feel hot to the touch. Turn ignition off and allow engine to cool. Check engine for coolant leaks. Check engine coolant level in degas bottle and fill as necessary.
