Needed an oil cooler replaced in my 6.0 powerstroke. I did my research online as to how to properly flush the coolant system as well as what parts are needed to replace the cooler.
My deltas before the replacement was 16 degrees apart after driving 65mph on a flat surface for 15 miles (ect=194 and eot=211). I gathered this info using torque pro app. Before I tested I let the truck sit for about 20 hours to get the cold soak reading. The eot and ect was 2 degrees apart.
I bought the oem oil cooler, both updated turbo pipes, restore, restore plus, 25 gallons of distilled water, 4 gallons of rotella elc coolant, and a few other various parts the internet recommended I replace while doing the job.
I drop the truck off and Adam was nice enough and said not to worry, we will get you fixed up. Three days later I pick up the truck. I drive it home using my torque pro app. Ect=194 and eot= 217. I had that bad feeling in the pit of my stomach. How can the oil cooler clog that bad within 30 miles of driving the truck.
The same day, I was leaving to go out of town for the weekend. The truck sat home while I was gone. I get home Sunday and went to check the coolant level. The degas bottle was empty. I added two gallons of 50/50. I noticed coolant pouring out of the bottom of the truck. It didn't leak when I drove it home so I really have no idea why it leaked then. So I call back bay diesel and spoke to Cole. He's the one that worked on the truck. Explained what's going on and they decided to come get the truck. They took it back and fixed a hose that ruptured. Adam said it wasn't their fault and said it just failed. Tried to charge me 2 hrs labor to fix it. We worked out a deal that if I came and got the truck, they wouldn't charge me.
Two days later I pick up the truck and leave. This time it's loud and sounds like it's sucking air. I call and tell them something isn't right and turn around and drive back. I tell Adam to drive it. He does and he pulls the truck into a bay. He said a turbo clamp on the exhaust was loose.
I leave the shop and the truck sounds great and runs great. During the 45 minute drive home I'm watching the deltas. When I get home ect=194 and eot=232.
At this point I knew back bay diesel was the wrong place to have taken the truck.
The next morning I empty the coolant myself and notice a lot of foam like a bubble bath as I'm draining the coolant. I get on Google and research. They must have used the restore and I'm hoping the restore plus, but they didn't flush it afterwards enough. I pull the two block plus, and the lower radiator hose as well as the peacock plug and flush it with tap water for over an hour. I filled it with tap water, drove it and drained it. Still lots of bubbles. I did a fill, drive and flush 4 more times and wasn't able to get rid of the all the foam. It was much less, but still present.
The long day of flushing is coming to an end as it's getting dark. I bought and added 3 1/2 more gallons of rotella elc coolant. I drive the truck a few minutes and top off the coolant. Once it leveled out and wasnt burping anymore coolant I took it out for the delta test. 65mph flat surface for 15 to 20 miles. Ect=194 eot=223. So it's better than 232, but still much higher than it originally was. I'm really upset as this was $$$$ to do and the truck is worse now than it was before the cooler was replaced.
Oh and lastly, I found their shop phone in my engine bay. Unbelievable.
