Removal And Installation

WARNING: To avoid personal injury, do not unscrew the coolant pressure relief cap while the engine is operating or 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 personal injury.
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 degas bottle-to-radiator hose.
3. Using a suitable suction device, siphon the coolant from the degas bottle.
4. Disconnect the radiator-to-degas bottle hose from the degas bottle.
