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:

z

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.

z

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.

z

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.

z

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.
