DEGAS BOTTLE REMOVAL/INSTALLATION - HYBRID
WARNING: Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure relief cap when the engine is
operating or the cooling system is hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened
slightly. Failure to follow these instructions may result in serious personal injury.
NOTE: The degas bottle has 2 separate reservoirs. The front (larger) reservoir is part of the engine cooling system. The rear (smaller) reservoir is part of
the motor electronics cooling system.
1. Release the pressure in the cooling system by slowly turning the pressure relief cap one half turn counterclockwise. When the pressure is released,
remove the pressure relief cap.
2. Using hose clamp pliers, clamp the engine coolant return hose and the motor electronics coolant return hose.
3. Using a suitable suction device, siphon the coolant from the degas bottle.
4. Disconnect the motor electronics coolant vent hose.
5. Disconnect the 2 engine coolant vent hoses.
6. Detach the pin-type retainer from the degas bottle.
7. Remove the degas bottle bolt and nut.
