Just been told today that truck has a P012F error code which requires a new oil cooler. Truck has 89,000 miles. Read a lot of posts where this is a common problem. Question: Should I opt for aftermarket oil cooler and/or go with air cooled approach? What are common issues to watch out for?
Diagnosed twice by ex 17 year Ford mechanic who has his own shop. Going to go slow on this. Went to local Ford shop and they were not very encouraging on flush as sole solution. Now here's the bad news---warranty expired on time in Jan 2013. It figures.
I think that makes sense and I will try flush first. Wrench light comes on after 20 minutes. After turning off and back on, it takes about 8 minutes for the wrench to come on again. I bought truck used in Feb 2013 with 83,000 miles. Don't use for towing or any heavy duty, just a short trip truck with maybe one 300 mile journey a month. Does Ford sell any sort of upgrade oil cooler for the 2008?
Just a thought but I think before I sprung the money for a new cooler I'd get a 2nd opinion, buddies experience aside.
If the cooler is gone you should be showing quite a temp difference between engine coolant and the oil temp. Maybe you can rent/borrow from one of the box stores something that plugs into the obd port and will give you actual temp readouts.
On that half kit you mentioned, I don't believe that replaces your factory cooler. If I understood the sales propaganda I think it only offers additional cooling and isn't meant to take the place of what's already there. If yours is completely gunked up I don't know that their kit is capable of going it alone. I'd be sure to ask before I dropped that kind of coin.
I have the same problem with my 08. Out of warranty but the lights only comes on when I tow. The external oil cooler from BPD is about 1300 bucks. Don't have to remove the reg. cooler which is nice. It should keep the temps down
X3 on what Senix says.
I could be wrong but these oil cooler failures, are they the same as the 6.0 failures where the coolant side of the cooler plugs and loses its ability to cool the oil properly? If so, then the rest of the system will be compromised with less flow and add more stress/heat to other components which could eventually fail too. I believe that could include egr coolers too. We don't want those to rupture...unless the 6.4 is different? Idk
