I just finished running through a full tank of gas since I did the last update. Good mix of short trips, highway driving, idling, etc. So far still the coolant looks to be pure and green. As soon as I get a chance to clear all the backlog around the house after the huge Texas freeze I will be...

Well, 3 more flushes seems to have done the trick. All clear! After the last flush, I drained all I could get out from the radiator and pulled the lower radiator hose. Then filled back up with Motocraft yellow going through a few fill cycles followed by a short trip to get gas and topped...

Sorry for the long delay in getting an update on this. I came back from my out of town trip and got swamped/buried from multiple angles. So I went ahead and used a legit Prestone flush/degreaser, running with the thermostat back in place to get to full temperature for about 80 minutes. After...

I did not. That would have been the smart thing to do before and after replacing the oil cooler. At least now if I did it and have no loss of pressure I would think that should give me a good indication the cooler was the issue. Maybe I should cut the old cooler in half with my carbide metal...

LOL...yeah, I was hoping for something that would my mind at ease, but sounds like this is the most common method. - Joe

Yeah, the back order thing initially scared me a bit, but once I got my local parts department on the phone on Monday morning they were able to find one in town and have it same day. I am curious if there is any easy/definitive way to determine that the cooler was the source of failure...

I have an update after squeezing in a few hours of flushing this evening. Looks like adding the degreaser and doing the constant/running flush were the keys to making a real dent in the oil content of the water (which is so obvious to me in hindsight). Greatly appreciate getting me steered in...

Thanks for all the feedback so far. I will certainly provide updates if I get to do some more testing tonight (and then I will be out of town for 4-5 days so bear with me for a brief lack of updates coming up). I haven't done any additional flushes after the first 3 limited "closed system" type...

Simple Green sounds like a good idea. I had to use a degreaser to get the reservoir clean. That was a mess! Currently flushing without a thermostat but I haven’t done a flush with the drain open and constantly filling yet. Will give that a try. Mostly been filling the radiator, starting engine...

It certainly seems like I have all the symptoms of a bad cooler. Maybe I will have to figure out how to test the coolers by somehow sealing the ends of the coolant in/out and pressuring it where I can measure any changes. I tried filling the first one with water laying on its back and let it sit...

Oil was a little low when I changed it but that was after ~10k miles (got a little behind schedule this time, usually every 7.5k) but previous change certainly didn’t show much oil consumption. Definitely looks and smells like engine oil. Good flow in the radiator. Thanks! - Joe

Looking for thoughts on what all I should do before I tear into the heads. 2014 118k, 2 weeks out of extended warranty, history of engine overheating at 60k about 3 years ago when radiator went out. Last week, just 3 days after I changed the oil and filter noticed an oil spot of driveway by...

Thank you for the link. I came to an understanding with the dealer that misdiagnosed the coolant leak the last time I gave it to them and they fixed all the issues that arose from the last visit. Had the truck back for a few days now and keeping my fingers crossed that everything is really...

Radiator on my 2014 finally gave it up. Blowing coolant from somewhere mid-high in all over the front of the motor. If I could find a dealership within 80 miles of NW Houston that would actually return my truck to me without breaking something else or doing shoddy work I would go the warranty...

Been smelling coolant for a few weeks but no obvious signs of a leak and the coolant level has been mostly stable. Had the dealer check it out and after a week and a half (actually only 2 test drives, but that is another story) they traced it to the lower radiator hose...which of course is not...
