Ill give you a brief account of what happened and you tell me what you think. 6 months ago, my truck went into Ford and had the #5 & #7 injectors replaced. 5 weeks ago, my truck began leaking coolant. Bring the truck into Ford, they find diesel in the coolant and tell me i have a cracked head/heads. Heads go to machine shop, and they pressure test and magnaflux them twice and cant find a crack. Then im told ford contacted an engineer who said it would have to be the fuel injector cups. I find out today from the diesel tech that when he pulled the heads, he found coolant on top of the #5 injector cup which leads him to believe the #5 cup is what the problem is. Just prior to replacing the 2 injectors 6 month ago, I did a coolant flush with restore and restore + and about 180 gallons of distilled water. I flushed it "by the book" and it took every bit of 12hrs, and replaced it with CAT 1 ELC concentrate. The diesel tech then says, "the engineer at ford said what most likely cause the #5 cup to leak was the red coolant you put in it!" IM CALLING B.S. Somebody please chime in and tell me what you think. Should I be responsible for this bill????

The coolant didn't cause it but I don't see why you wouldn't be responsible. You had injector failure the first time in, nothing to do with a coolant issue.

So you think I should have to pay the bill? Might have misunderstood your post.

I guess I don't understand why you wouldn't have to. It's in there now for a completely different problem. Not trying to be a d**k, maybe I'm missing something.:dunno:

Guess what im getting at is this: fuel injector cups can crack when a fuel injector is replacing and pushed or torqued down to hard. I just dont see it being a coincidence that they replaced the #5 injector in my truck 6 months ago, and now the #5 injector cup is cracked.

I see your point, however, I would say that the cup would have cracked and you would have had an issue immediately after the injectors were replaced and not 6 months later.

In my situation, my truck is by no means a daily driver. I put 10,000 miles on it in the past 20 months. The problem was from the diesel fuel eating away at the oring and gasket. This obviously isnt something that happened overnight....im sure it took time. I get what your saying. I posted this to see what other people thought of my situation. Just trying to get a feel from what others think so I know how to react when I get the bill.

I hope it works out in your favor. I guess the thing to do would be hope for the best and prepare for the worst.

The repair facility got carried away with the heads, but should have thought to check out the cups as well. It is a simple test and usually would not take very long to complete. However, the smaller the leak, the longer it takes. I guess you could call what they did an incomplete or bad diagnosis.

It is obvious now, there was no reason to pull the heads and send them for work. There is no organic solvent in ELC that will damage a cooling system, so it will not damage the green loctite (sealant). However, since the pressure from the fuel system is higher than the coolant, it will get in the coolant system, and over time it will damage seals and hoses in the coolant system. So your discussion about what you pay them should stem around them not following the proper diesel diagnosis procedure. I don't know what they are charging you, but this should have been a simple and fairly inexpensive job.

Thanks Two! That is what I was thinking. I am by no means a diesel tech, but I was fairly confident that this was mis-diagnosed from the beginning. I know this is going to be a fight with them over the bill, but I feel like this could have been addressed differently. Just out of curiosity, how do they test the cups?
