What color anti-freeze do I need for a 2011 -2015 Ford F-350 a 6.7 Super Diesel?

RESPONSE

• Motorcraft® Orange Antifreeze/Coolant Concentrated
  VC-3-B (US); CVC-3-B2 (Canada)
• Motorcraft® Specialty Orange Engine Coolant Revitalizer
  VC-12

Use only Motorcraft® Specialty Orange Coolant Revitalizer VC-12 as an additive to Motorcraft® Specialty Orange Engine Coolant. Do not mix with or add any other coolant additive. Use of any additive other than Motorcraft® Specialty Orange Coolant Revitalizer VC-12 degrades the corrosion protection of Motorcraft® Specialty Orange Engine Coolant and may damage the engine or cooling system components.

If the cooling system has been drained due to a repair, fill a clear, clean approximately 1 L or 1 qt container with coolant from the drain pan. If the coolant has not been drained from the cooling system, open the radiator draincock to fill a clear, clean approximately 1 L or 1 qt container with coolant.

During normal vehicle operation, Motorcraft® Specialty Orange Engine 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.

What color anti-freeze do I need? Inspect the coolant color

1. Discoloration may indicate that incorrect coolant may have been added to the system. Use of incorrect (green or yellow in color) coolant degrades the corrosion protection of Motorcraft® Specialty Orange Engine Coolant. Addition of Motorcraft Specialty Green Engine Coolant may cause the color to appear to be a murky green-brown color. The addition of Motorcraft Premium Gold Coolant, however, may not change the color or appearance of the orange colored coolant. Detection of contamination with Premium Gold Engine Coolant is determined by the presence of nitrite. Flush the system and refill with the correct mixture of distilled water and Motorcraft® Specialty Orange Engine Coolant.

• A darker orange with the presence of debris could indicate a commercially available stop leak may have been used and could result in loss of coolant flow to critical parts of the engine. If sediment is present in the coolant sample, flush the system and refill with the correct mixture of distilled water and Motorcraft® Specialty Orange Engine Coolant.

• A light or reddish brown color indicates that rust may be present in the cooling system. Flush the system and refill with the correct mixture of distilled water and Motorcraft® Specialty Orange Engine Coolant.

• An iridescent sheen on top of the coolant could indicate a trace of oil is entering the system.  Flush the cooling system and refill with the correct mixture of distilled water and Motorcraft® Specialty Orange Engine Coolant.

• A milky brown color may indicate that engine oil is entering the cooling system. Pressure test the cooling system.  If engine oil is suspected, the cause of the leak may be internal to the engine.  Flush the cooling system and refill with the correct mixture of distilled water and Motorcraft® Specialty Orange Engine Coolant.
