Cooling System Draining, Filling and Bleeding: Draining

WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. 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: Always fill the cooling system with the manufacturer's specified coolant. If a non-specified coolant has been used the cooling system must be chemically flushed. Refer to COOLING SYSTEM FLUSHING - WITHOUT FUEL OR TRANSMISSION FLUID CONTAMINATION . Failure to follow these instructions may damage the engine or cooling system.
NOTE: Recover the coolant in a suitable, clean container for reuse. If the coolant is contaminated, dispose of it properly and fill the system with new coolant. Flush the cooling system. Refer to COOLING SYSTEM FLUSHING - WITHOUT FUEL OR TRANSMISSION FLUID CONTAMINATION  or COOLING SYSTEM FLUSHING - WITH FUEL OR TRANSMISSION FLUID CONTAMINATION . Failure to follow these instructions may damage to the cooling system.
NOTE: During normal vehicle operation, Motorcraft Orange Antifreeze/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.
  1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING .
  2. Place a suitable container below the radiator draincock.
  3. Remove the pressure relief cap from the degas bottle.
  4. Open the radiator draincock and drain the coolant into a suitable clean container.
  5. Close the radiator draincock when finished.
  6. If necessary, disconnect the transmission fluid cooler inlet hose from the transmission fluid cooler and the fuel cooler outlet hose from the fuel cooler to completely drain the system. Drain the coolant into a suitable clean container. Reconnect the hoses when finished.
