Cooling System Draining, Filling & Bleeding: Draining
WARNING: This page is about a different car, the 2010 Lincoln Town Car. 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 and replaced. Using contaminated coolant may damage cooling system components or the engine.
NOTE:
Vehicle cooling systems are filled with Motorcraft Premium Gold Engine Coolant or equivalent (yellow color) meeting Ford specification WSS-M97B51-A1. Always fill the cooling system with the same coolant that is present in the system. Do not mix coolant types. Mixing coolants may degrade the coolant's corrosion protection.
NOTE:
Less than 80% of coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires the system flush and replacement.
- 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.
- Place a suitable container below the radiator draincock and drain the radiator.
- Close the radiator drain cock.
