Another Oil cooler story
Just thought Iíd chime in on yet another oil cooler change out. First a little background. I bought a 05 6.0 F-250 4x4 about a month ago. I have read through all the threads about the problems everybody has had so I thought I would wait until everything was done before posting. I bought this truck in horse country of Tennessee. A lot of these trucks are bought for show and have not seen more than a 2 horse trailer hooked behind them. The one I bought had a ball in bed but no scratches, leading me to believe it hasnít saw much work. I was told the older guy that traded it in changed the fluids on time. Knowing these trucks I felt better doing all the fluids again. First thing I did was install an edge cts. I saw my ECT and EOT delta was over 15 degrees. Normal driving I was at 192 Ė 207, loaded with a light cattle trailer (6k) I was at 204- 217. I knew I would be pulling heavier loads than this. I needed to take care of a few things. I started flushing with Restore. Temps went higher 192 Ė 209. I didnít see any jellyfish, slime, sand, snot or anything weird. I then used DC-9, I saw some orange colored water and the temps climbed a little more, 192 -212. I flushed everything with 25 gallons of distilled H2O. I installed a coolant filter and took it to the Ford place for the rest. I just donít have the time. I had them install an oil cooler, 3C3Z6A642CA, BPD EGR cooler, new BPD turbo drain tube, HPOP STC fitting upgrade, 4C3Z9B246F, intake gaskets 3C3Z9433BH, fuel regulator spring upgrade, 3C3Z9T517AG,fuel filter kit, FD4616, Flush transmission fluid, XT5GM & XT5QM, element, FT145, replace radiator drain that I broke, F0AZ8115A, a hose clamp, F81Z8287EA, and clean the turbo. And change the oil in case anything dropped through from the other repairs. Total parts and labor was $2388.58.
I have only put a few miles on it, but the temps now are in sync with each other. The ECT temp is 196 and EOT is 202. You can see the oil temp come down when the thermostat opens. It is definitely exchanging heat. I have not hooked a heavy load to it yet but Iím not expecting any problems. As far as I know the truck was completely stock. I donít plan on doing any tuning but If I do Iíve do the studs then. I know I ainít done everything, but in my opinion this will suffice for a stock truck unless something else comes up.
