Cooling System Draining, Filling and Bleeding: Draining
WARNING: This page is about a different car, the 2012 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.
NOTE:
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. Failure to follow these instructions may result in engine or cooling system damage.
NOTE:
Less than 80% of the coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement.
NOTE:
During normal vehicle operation, Motorcraft Specialty Orange Engine Coolant may change color from orange to pink or light red. As long as the engine coolant is clear and uncontaminated, this color change does not indicate the engine coolant has degraded nor does it require the engine coolant to be drained, the system to be flushed, or the engine coolant to be replaced.
- With the vehicle in NEUTRAL, position it on a hoist. For additional information, REFER to JACKING & LIFTING .
- Make sure the engine is cool.
- Wrap a thick cloth around the pressure relief cap. Slowly turn the cap counterclockwise until the pressure begins to release.
- Step back while the pressure releases.
- When 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.
