I spoke to Ford customer relations this morning.
They were really tight lipped, especially when I mentioned the ongoing or new investigation. They didn't mention go into the dealership for this dummy coolant light fix. I did mention that due to sub-par cooling aspect of the oem radiator etc., I replaced it and they said to save receipts of what I did for future reference. Refund my costs. Only 25k on the car currently.
As for information about this recall, whether or not replace the head and/or engine, they wouldn't say, as they had no information to run with. They are, apparently, still gathering information about what to do or how to fix the problem. They said to wait for the letter, which is being mailed out the week of April 18th, for further details etc. which would be available then.
Grrrr!
