I decided to start a new post since the other one has gotten so long.

So, once again Ford has updated this TSB. First it was the venturi tee that was causing radiators to break, then it was hyper-extended thermostasts, and now it is the leaking o-rings inside rad hoses that cause low coolant which stresses the radiator causing it to break.

So for everyone, the new TSB is 11-6-6. As part of this tsb, if you have a leaking o-ring inside one of the rad hoses or the appearance of dried coolant indicating a leak and your radiator is leaking then all of the repair is CODED to 8590 which is the o-ring which is covered for 5 years/100000 miles.

As part of the repair, they replace either or both radiator hoses-they have been redesigned to include 2 o-rings. The radiator is replaced of course, as well as the reservoir and cap. Which is why as of this posting, the reservoirs are on national back order.

So if you have a leaking radiator, take a good look at those hoses and see if they are leaking as well and it will be covered by the warranty.

I feel bad for all those people who had to pay out of pocket for a radiator repair when it may have been simply caused by a cheap o-ring that now Ford is covering under warranty.

 

Here is the TSB:

TSB
11-6-6 • 6.4L - RADIATOR LEAKING COOLANT
[************]Publication Date: June 3, 2011[/color]

FORD: 2008-2010 F-250, F-350, F-450, F-550



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

Also sucks for those of us that had a bad O ring and all they did was replace it and nothing else. Kind of hoping for another O ring leak now. Wonder if they extend that O ring warranty if you buy the 2/100K warranty.

 

how do I make it leak to get it fixed under warranty?

 

Easy, drive it ...............

 

Good info, added to tech folder!

 

Doggone it! My upper radiator hose cost me a short year ago. Are they saying it now has the 100,000 mile/5 year warranty too?

 

I just replace the lower hose o-rings, Before I did it I called ford service and was told not covered under 5/100 warranty.

 

I haven't had a radiator issue yet other then the addition of the venturi, but good to know if that changes.

 

My dad just got bent over to the tune of $1157.00 for a radiator less than a week ago. I was told he was getting a break on labor as well as parts(ya right) I am pretty sure it won't do any good but I will contact the service mgr. to see if they can go back on this tsb.

 

O-rings insided the radiator hoses have a basic code of 8590. When coded this way, it is covered for 5yrs/100,000 miles.

 

The cost for o-rings wasn't bad, But it would have been nice to get new hoses.

 

Sounds like you need a new dealer if they wouldn't replace them under warranty, had mine done late last year with 73K miles all covered under warranty.

 

Looks to be dated june 3, print it out and take it with you. I don't think they have a leg to stand on. They probably just didn't know about it.

 

My dealer told me it was not covered. I had 25K on the truck but 37 months. They denied it "on time". Service manager said that "it's normal for the o-rings to go bad at 25K.
I've had Ford trucks since 1970. This 2008 F350 CC 4X4 King Ranch will be my LAST Ford ever (POS engine). 10.3 MPG AVG and 7.5 pulling. Dealer tells me "that is good".
Tried a Diablo Predator tuner, BIGGEST POS on the market. Got WORSE MPG.
Going to try Dodge 3500 4X4 Longhorn next.
