Engine Cooling System: Maintenance Mercury Montego III

Draining

WARNINGNever remove the pressure relief cap while the engine is operating or when the cooling system is hot. Failure to follow these instructions can result in damage to the cooling system or engine or personal injury. To avoid having scalding hot coolant or steam blow out of the degas bottle when removing the pressure relief cap, wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it slowly. Step back while the pressure is released from the cooling system. When you are sure all the pressure has been released, (still with a cloth) turn and remove the pressure relief cap. Failure to follow these instructions can result in personal injury.
CAUTIONThe coolant must be recovered in a suitable, clean container for reuse. If the coolant is contaminated it must be recycled or disposed of correctly.
CAUTIONAll vehicle cooling systems are filled with Motorcraft Premium Gold Engine Coolant VC-7-A or equivalent meeting Ford specification WSS-M97B51-A1 (yellow color). Always fill the cooling system with the same type of coolant that is present in the system. Do not mix coolant types.

Note. The addition of Cooling System Stop Leak Pellets, VC-6, darkens Motorcraft Premium Gold Engine Coolant from yellow to golden tan.

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. For additional information, refer to «JACKING & LIFTING»(ref-232992) .
  2. Release the pressure in the cooling system by slowly turning the pressure relief cap one half to one turn counterclockwise to the first stop on the filler neck. When the pressure has been released, remove the pressure relief cap.
  3. Remove the front splash shield.
  4. Place a suitable container below the radiator draincock. Drain the coolant.
  5. Close the radiator draincock and install the front splash shield when finished.
