This article supersedes TSB 11-1-7 to update the Issue Statement, Service Procedure, Part List and Service Labor Time Standards. ISSUE:

Some F-Super Duty vehicles equipped with a 6.4L engine may exhibit an external coolant leak from the radiator. Slow leaks at cooling system hoses/connections can lead to low coolant levels. Excessive hot and cold cycling associated with low coolant levels can cause stress within the radiator tubes, possibly resulting in cracks in the tubes.
ACTION:

Follow service procedure steps to repair this concern.
SERVICE PROCEDURE



Thermostat inspection is no longer required because IDS release 71.04 and later added a cooling system monitor.
1. Inspect for the cooling system venturi tee being installed and verify proper orientation. Refer to Workshop Manual (WSM), Section 303-03, Degas Bottle - 6.4L Diesel.
2. Degas bottle port inspection and repair:
1. Dual-port design requires the degas bottle to be replaced with the single-port design and a new degas bottle cap. (Figure 1) Proceed to Step 3.


Figure 1 - Article 11-6-6
2. Single-port design requires inspection of the degas bottle cap sealing surface for nicks and/or cracks. If present, replace the degas bottle and degas bottle cap. Proceed to Step 3.
3. Coolant leak inspection and repair:
1. Visually inspect all cooling system hoses/connections for evidence of coolant loss such as white coolant residue (dried coolant) or liquid coolant and repair as necessary. (Figure 2)


Figure 2 - Article 11-6-6
2. If a leak is found at a radiator hose O-ring seal, the radiator hose should be replaced. The upper and lower radiator hoses have been updated with a dual O-ring seal design for improved sealing.
4. Replace the radiator. Refer to WSM, Section 303-03.
1. Be sure to remove the engine coolant block plugs from both sides of the engine to drain the coolant from the engine block.
2. Fill the cooling system with a 50/50 mixture of distilled water and new Motorcraft® Premium Gold Engine Coolant. Do not reuse coolant that was drained from the cooling system.
3. Utilize the Rotunda Heavy Duty Airlift II radiator refiller tool (UVU550500INT) or equivalent when filling the cooling system. Filling without use of the Heavy Duty Airlift II radiator refiller tool may leave excessive air in the system
