ISSUE
A new, extended-life engine coolant, yellow-colored Motorcraft Premium Gold Engine Coolant, meeting Ford Specification WSS-M97B51-A1, service
part numbers VC-7-A and VC-7-C (for use in the U.S., except California and Oregon) and VC-7-B (for use only in California and Oregon as it contains a
bittering agent), has been equipped in all of the vehicles noted above. The initial-fill life for this coolant is 100,000 miles/5 years. Due to variations in
water quality, the replacement interval is 50,000 miles/3 years.
ACTION
Any time the addition of coolant or a coolant change-out is required, USE ONLY THE TYPE OF ENGINE COOLANT WITH WHICH THE VEHICLE
WAS ORIGINALLY EQUIPPED. DO NOT MIX COOLANT TYPES. To determine the type of coolant required, check the color of coolant in the
coolant reservoir of the vehicle or refer to the applicable vehicle's Owner's Guide or Workshop Manual for service parts and specification information.
SERVICE INFORMATION
Except for heavy-duty vehicles equipped with the Caterpillar 3126E engine, the use of a supplemental coolant additive (SCA) such as Motorcraft
Heavy-Duty Cooling System Additive, service part number FW-16, is not required in conjunction with this coolant.
Testing is currently underway to determine the backward compatibility of the Motorcraft Premium Gold Engine Coolant in vehicles equipped with the
green-colored Motorcraft Premium Engine Coolant, service part numbers VC-4-A, VC-4-B, and VC-5. Until the final test results are available, vehicles
should ONLY be serviced with type of coolant with which they were originally equipped.
Please note that Motorcraft Premium Gold Engine Coolant is not compatible with any orange-colored, extended-life engine coolants such as Motorcraft
Specialty Orange Engine Coolant, service part numbers VC-2 and VC-3. DO NOT MIX COOLANT TYPES. USE ONLY THE TYPE OF COOLANT
WITH WHICH THE VEHICLE WAS EQUIPPED.
Failure to follow these guidelines may result in degradation of corrosion protection and potential engine damage.
Coolant Discoloration:
The current Motorcraft Cooling System Stop Leak Pellets, service part number VC-6, used in both Production and Service, cause the yellow-colored
Motorcraft Premium Gold Engine Coolant to change color ranging from a light golden brown to dark brown, depending upon the amount of pellet
