Wrench Light - P012F Code

Ok brand new the diesel scene. I purchased a 2008 Ford F250 6.4L, and on my way home it threw up the wrench light. I had Autozone run the code and said it was P012F - coolant/oil issue. Nothing else appears to be wrong, it's not over heating etc. Truck has 128k on it, any ideas?

Clogged oil cooler? I think, someone else should chime in.

But if it were the oil cooler, wouldn't the truck be over heating?

The water passages are known to clog in the oil cooler, that causes the oil to get to hot. I don't know if it will throw a code or not. Clogged oil coolers are common on these trucks.

Do you have a way to check the difference between the ECT and EOT when the truck is at normal operating temperature?

Well my wife dropped the truck off at Ford today or me, and they stated it's the oil cooler. Total repair cost $5053.41

I bought the truck Saturday, and drove off the lot with the premise that it was in working order. The repair invoice has been forwarded to them, and I'm awaiting to see if they're going to pay it. If not then looks like they'll have to send someone to come pick up their truck. I live in Texas, they're in Louisiana.

That seems like a lot to put a new oil cooler in. Another option is the BPD oil cooler half kit and you could probably install it by yourself.

Update - dealer I bought it from said they would tow it back to La, fix it and send it back to Tx. I don't trust them so I said no. But I did go to another shop in town that does performance diesel work that I've heard good things about, and they quoted me $2177 to do the work. Place I bought the truck from agreed to pay them to do it, so truck is in route being towed over there.

An a/m engine oil cooler? The OE isn't that pricy, are there a/m alternatives that are aroud the same price?

Also while they've got it all apart, should I have them do anything else maintenance wise? It has 129k on the ODO.
