Hello all,

I recently purchased my first diesel, a 2017 F250 with the 6.7l in it. The truck has about 64,500 miles on it and I'm getting a P00BD trouble code on it. This has occurred repeatedly for the last month or so. I've checked the MAF sensor, cleaned it (although it looks brand new) and started looking for possible other issues since the code indicates too high an air volume. I found that the intercooler cold side hose (I believe that's the correct hose) has a couple of splits in it (see pics). I will be replacing this hose as I know it needs to be replaced. My question regarding the hose is - is it worth it to spend the money for an "upgraded" kit or just buy another hose and change it? I don't plan on doing a whole lot to get any more power out of this beast, but I want it to last without having to replace it every 3-4 years. Also wondering about replacing the upper radiator hose (the one with the heat shield wrap on it. Is all the crud on the hose and the vacuum lines from this intercooler tube leaking? Also, could this help my DTC by replacing the intercooler tube?

Appreciate any help or advice that is offered.


Intercooler cold side tube

Intercooler tube and upper radiator hose.

 

something happened there in those pics. What was it or was it that way prior to ownership. The hoses in the pics need replaced, both of them. That very well maybe part of the issue. Repair, clear DTC's and see what you have.

Also have you checked the plastic on the inter cooler cold side? Those have know to be a failure point.

 

Something got very hot in that area. You didn't get the whole story yet.

 

Those hoses were like that prior to me buying the truck. I do plan on replacing both of the hoses as soon as I can find them. I'll definitely replace, clear DTC's and then see what happens. I'll also be looking at the other hoses on the inner cooler to see if they are toasted or not. Thanks Senix for the additional info!!!

As stated in original post, I've owned the truck for about 3 1/2 months, put about 3700 miles on it in that time. Never noticed anything wrong with it till the check engine light came on. When I pulled the codes, it gave me a P00BD error which I outlined above. This all started about 2 weeks ago, so I'm not sure if this was something that happened before I got the truck, but I have a feeling it has been exacerbated since I've had the truck, thus the check engine light coming on. I don't see any signs of anything other than the hose having the splits in it, but I believe it's been there for a while since the radiator hose has the heat wrap messed up like that. Working on getting the hoses so that I can replace them ASAP.

Thanks guys!!!

 

I had to replace both hoses in mine to. The boost hose gets a little weak, expands under load and rubs the radiator hose.
Hope ford has them in stock they were back ordered for me.

 

There are a number of threads on here where people have replaced the cold side hose from the intercooler to TB because of problems with the plastic (not the actual hose like yours) as outlined by Senix. I replaced mine like others with a metal tube and flex adapters before a power robbing failure could occur while away from home. Pretty surprised by the appearance of your hoses on such a relatively new truck. I'm not used to seeing cracks like that until the hose has a lot of age on it or extreme heat.

Popular aftermarket tubes are a peace of mind even if you have no plans on boosting your truck's power level. I used AFE, but Rudy's has probably been the most popular on here.

 

There have been very few issues on the 2017+ with the cold side hose. But you have a unique case there. Something bad happened in that area and it wasn't completely fixed. Anything in that general area should be suspect and a candidate for replacement.

 

Well, after spending several hours looking online and calling dealers, I finally ordered the radiator hose and the intercooler tube from profordparts.com. The didn't have the intercooler tube in stock, but said they could have it Tuesday and would ship it out for me ASAP. Their prices were about the cheapest I found and shipping was incredibly cheap as well. Overnight rates were only about $3 more than standard shipping and expedited shipping was actually cheaper than standard shipping. I decided to go with stock parts for now and I'll upgrade the intercooler tube later on. I'm also going to investigate and see if there was something else that may have sped up the hose going bad like it did. The smaller lines above those hoses in the pick are vacuum lines, so I don't think that would be an issue. I'll dig around some more and see what I can find.

The crazy thing on the parts is that most places had the intercooler tube in stock, but not the radiator hose. Most online ordering sites stated either backordered or no longer available. Don't know why since it's common on the 2017 - 2019 models as far as I can tell. Probably the 20's and '21's as well. And around my neck of the woods, none of the dealers had both in stock. They either had one or the other. Plus their prices were +30% higher than what I found online. Same hoses I bought for $75 each, the dealer wanted $120 each. So I'll park the truck for a few days and fix it when the parts come in. My g'f still has her car so we have transportation and I have my bike. All's good now.

P.S. Thanks for all the info guys. Still learning about this truck's engine and I have a long ways to go it seems.

 

I would highly suggest replacing all hoses that are not in a good condition. I also agree with going to stock for everything for now.

Once you have all the DTC's ironed then you can think of upgrades.

 

Thanks, Senix. That's my plan for now. New intercooler tube and radiator hose on order and should be here later this next week (hopefully by Thursday). I'm taking a trip for the next few days, but the truck is staying home as I don't know what kind of damage can be done with these issues. I've driven it longer than I probably should have since the check engine light first came on, so hopefully by getting it parked and getting it fixed, I won't hurt it any more.

 

Well, I thought I'd have the hoses by now, but they're due to be delivered tomorrow. Hopefully I'll get to replace them and then drive it to see if the codes come back. I'll let y'all know how it goes.

 

Well, I finally received the new hoses. Pretty sweet setup with Ford OEM hoses. They come with the collar for the upper end of the intercooler hose and the lower hose clamp in place. The radiator hose had the slip on collars with the clips on them. The hardest part was draining the coolant out of the radiator. Tight fit to get in there and open the petcock. And messy if you don't have a drain tube to stick on the bottom nipple to drain into a bucket. But I got it all changed and took it out and drove it and so far everything is good. I'll find out after driving it some more to see how it does on the road.

Senix, after doing some research, it appears that the cold side intercooler hose is prone to blowing out like that. I've seen several comments and videos from others that say that hose is a weak spot in the system. Mine blew oil from the intercooler hose up and onto vacuum line and the small cooler line running across there and then onto the radiator hose. That's what caused the damage to that hose. The new hose didn't have that big insulation around it, just a small black piece of protection on the hose, but it's in the exact spot where the intercooler hose would blow crap on it if it blew out again. Glad I replaced both. I'll let y'all know if anything else happens with these hoses.

 

That point of failure seems to be on the pre-2017 models. I don't think there is enough evidence to say that the same problem exists on 2017+ models.

 

hope that is the cure, thanks for reporting back on the progress.

 

Well, I don't know if that fixed all of it or not, but I took it out and drove it, got it up to normal operating temp and all seemed fine. But then the CEL occurred again. I checked it while it was on and it came up with a P0402 code this time. This code is for the (EGR) Flow Excessive Detected. I'm looking online for info, but most of what I am finding is either for gas engines, or for older vehicles. I'm trying to find out if it's the EGR that's the issue or if it's the DPFE that's tripping this alert. Time to do more digging. First time working on a diesel so it's all new to me. I'm having to learn as I go. Another update to come!!!
