Cooling System Specifications: Coolant
WARNING: This page is about a different car, the 2004 Mercury Mountaineer, 2004 Ford Explorer, 2003 Mercury Mountaineer, and 2003 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Never remove the radiator cap under any conditions while the engine is operating. Failure to follow these instructions could result in personal injury and/or damage to the cooling system or engine. To avoid having scalding hot coolant or steam blow out of the radiator, use extreme care when removing the radiator cap from a hot radiator. Wait until the engine has cooled, then wrap a thick cloth around the radiator cap and turn it slowly to the first stop. Step back while the pressure is released from the cooling system. When you are certain all the pressure has been released, press down on the radiator cap (with a cloth), turn and remove.
NOTE:
The addition of Motorcraft Cooling System Stop Leak Pellets (VC-6), darkens Motorcraft Premium Gold Engine Coolant from Yellow to Golden Tan.
When adding engine coolant, use a 50/50 mixture of engine coolant and distilled water. To maintain the integrity of the coolant and the cooling system:
- Add Motorcraft Premium Engine Coolant VC-4-A (in Oregon VC-5, in Canada CXC-10) or equivalent meeting Ford specification ESE-M97B44-A (Green color), Motorcraft Specialty Orange Engine Coolant such as VC-2, meeting Ford specification WSS-M97B44-D or Motorcraft Premium Gold Engine Coolant VC-7-A or equivalent meeting Ford specification WSS-M97B51-A1 (Yellow color). Use the same coolant that was drained from the cooling system. Do not mix coolant types.
- Do not add/mix Orange-colored Motorcraft Speciality Orange Engine Coolant VC-2 or equivalent meeting Ford specification WSS-M97B44-D. Mixing coolants may degrade the coolant's corrosion protection.
- Do not add alcohol, methanol, or brine, or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing.
- Do not mix with recycled coolant unless it meets the requirements of Ford specification ESE-M97B44-A or WSS-M97B51-A1. Not all coolant recycling processes meet these Ford specifications. Use of such coolants can harm the engine and cooling system components.
