Changing engine oil cooler

I have a pin holes leak in the elbow that comes out of the engine oil cooler just above the oil pan that is closest to the universal joint on the front driveshaft. It looks like it was crushed by something and has pin holes leak spraying on the universal joint. I ordered a new cooler from Ford and the o-rings.

Do I need to drop the oil to replace this or is the cooler above the oil level? I just changed oil and like to not replace it if not necessary.

Any other advice?

Thanks
Chris

So my guess is you will have to follow the second procedure as you will have the nut inside the pan.


Also what is the actual sequence for the 7 bolts?

Thanks for providing that info. I knew there was a nut inside the pan; did not know on later build engines that was done away with.

I always wondered why Ford would make this service procedure that much harder for no real reason.

I believe when they changed to the metal pan the internal nut was deleted.

Good point - the timing is about right.

Two questions - why did they use a plastic pan in the first place, and then once they did, why did they revert back to stamped steel?

If I had to guess, it would be because of all the Ford stamped oil pans which rotted out over the years...but the plastic ended up not being as durable against leaks or damage...

The one issue I have seen numerous times concerning the composite pan was the drain plug eventually leaking and the pan seeping around the lip.

I have the replacement cooler and it doesn't have the stud on it. I haven't pulled the old one to see if it has the stud. I Ford dealer looked the part up via my VIN number, so I'm assume it's correct. Any chance that the cooler on the truck has the stud, but when I replace it, I won't need to use the nut or do I have the wrong cooler?

I have the composite pan.

Just to follow up on my question above about the replacement cooler not having the stud on it. I talked to the dealer and there is a note for the replacement cooler that states the replacement cooler will not have the stud. The hole for the stud in the upper oil pan is sealed with the body of the cooler along with the seal. So good news for us 2011 models is if we have to change it again, we won't have to drop the lower oil pan.

I did this yesterday. I was able to pinch off the coolant lines, so I didn't need to drain the coolant. Took about 3 hrs. A lift would make this much easier. Laying on your back/side with your arms up working takes its toll. About a quart of oil came out of the cooler/upper oil pan when it comes free from the housing. So be ready for that.
