Cooling System Draining, Filling and Bleeding: Draining
WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
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.
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. Using contaminated coolant may damage cooling system components.
CAUTION:
Vehicle cooling systems are filled with Motorcraft Premium Gold Engine Coolant (yellow color). Always fill the cooling system with the same type of coolant that is present in the system. Do not mix coolant types. Mixing coolant types degrades the corrosion protection of Motorcraft Premium Gold Engine Coolant and may result in cooling system damage.
NOTE:
The addition of Cooling System Stop Leak Pellets 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.
- Make sure the engine is cool.
- Wrap a thick cloth around the coolant pressure relief cap on the degas bottle. Slowly turn the cap counterclockwise (left) until the pressure begins to release.
- Step back while the pressure releases.
- When you are sure all the pressure has been released, use the cloth to turn and remove the cap.
- Place a suitable container below the radiator draincock. Drain the coolant.
- Tighten the radiator draincock when finished.
