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 OIL CONTAMINATION . Failure to follow these instructions may result in damage to the cooling system.
NOTE: Recover the coolant in a suitable, clean container. If the coolant is contaminated with a radiator sealant or stop-leak, oil or combustion by-products it must be recycled or disposed of correctly and the system MUST be chemically flushed. If the cooling system is drained to make a repair to a cooling system component where evidence is seen of aluminum erosion or cavitation, the coolant must be recycled or disposed of correctly and the system MUST be flushed out with water to remove all particulate contaminants and MUST be chemically flushed. Refer to COOLING SYSTEM FLUSHING - WITHOUT OIL CONTAMINATION . Failure to follow these instructions may result in 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.
NOTE: Less than 80% of coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement.
  1. With the vehicle in NEUTRAL, position it on a hoist. Refer to JACKING & LIFTING .
  2. Disconnect the battery ground cable. Refer to BATTERY, MOUNTING AND CABLES .
  3. Remove the pressure relief cap from the degas bottle.
  4. Place a suitable container below the radiator draincock.
  5. Open the radiator draincock and drain the coolant into a suitable clean container.
  6. Close the radiator draincock when finished.
  7. Remove the RH fender splash shield. Refer to FRONT END BODY PANELS .
  8. Completely cover the starter with waterproof plastic.
  9. NOTE: Use of a long ball-end hex bit socket eases removal of the drain plug.

    Remove the drain plug and drain the coolant from the RH side of the engine block.

    • Install the drain plug when finished and tighten to 60 Nm (44 lb-ft).
  10. Remove the waterproof plastic from the starter.
  11. Release the clamp, disconnect the engine-to-engine oil cooler hose from the engine oil cooler and drain the coolant from the LH side of the cylinder block.
    • Connect the engine-to-engine oil cooler hose and position the clamp when finished.
