WARNING:
Never remove the pressure relief cap while the engine is operating or when the cooling system is hot. Failure to follow these instructions can result in damage to the cooling system or engine or result in personal injury. To avoid having scalding hot coolant or steam blow out of the degas bottle when removing the pressure relief cap, wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it slowly. Step back while the pressure is released from the cooling system. When certain all the pressure has been released, (still with a cloth) turn and remove the pressure relief cap. Failure to follow these instructions can result in personal injury.
CAUTION:
Some vehicles cooling systems are filled with Motorcraft Premium Engine Coolant (VC-4-A; in Oregon VC-5; in Canada CXC-10) Green color. Others are filled with Motorcraft Premium Gold Engine Coolant (VC-7-A) Yellow color. Always fill the cooling system with the same type of coolant that was drained from the system. DO NOT mix coolant types.
CAUTION:
The coolant must be recovered in a suitable, clean container for reuse. If the coolant is contaminated, it must be recycled or disposed of correctly and the system filled with NEW coolant.
