Partial Drain
WARNING: This page is about a different car, the 2004 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
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 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 you are sure all the pressure has been released, (still with a cloth) turn and remove the pressure relief cap. Failure to follow these instructions may result in personal injury.
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.
CAUTION:
The engine cooling system is filled with Motorcraft Premium Gold Engine Coolant VC-7-A (in Oregon VC-7-B, in Canada VC-7-C) or equivalent meeting Ford specification WSS-M97B51-A1 (yellow color). Always refill the cooling system with the same coolant that was drained from the system. Do not mix coolant types.
NOTE:
The addition of Motorcraft Cooling System Stop Leak Pellets, VC-6, darkens Motorcraft Premium Gold Engine Coolant from yellow to golden tan.
NOTE:
Less than 80% of the coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty, or contaminated coolant requires replacement.
- Remove the degas bottle cap.
- Place a suitable container below the radiator draincock. Drain the coolant.
- Close the radiator draincock when finished draining.
