Hello All,

Well, my degas tank sprung a leak. It's a five year old Dorman unit. Guess I'm lucky it lasted this long. I am looking at one on ebay. I know it's Chinesium, but it's got a pressure sensor bung on the bottom. So I was thinking of trying it. Anyone have experience with this particular unit? Link below. Thanks, B.

Not that particular one, but I’ve got one from Accurate Diesel that has the same sight window. The sight window itself starts to leak after a few months. The replacement I got under warranty did the same thing. I ordered an actual good quality replacement from JW Winco

 

Accurate Diesel is not too accurate. I’d find a Motorcraft degas from a salvage yard or try tfunk’s recommendation.

 

That one has an odd cap. I'd atleast get one with a standard cap or Motorcraft style cap like this one. https://www.ebay.com/itm/255127684192

 

Yeah I noticed that as well. If the one I linked has a proprietary cap, then it's worthless. B.

 

I had bought a Ford part from Tasca and compared it to the Dorman degas bottle. I could not see any difference. The sharp edges on both indicate a China product.
Personally, I do not like the aluminum tanks, I always want to have the color and cleanness of the coolant in view.

 

Very valid point Hartwig. B.

 

Having much experience in the plastics manufacturing industry (bulk plastic, usually in pellet form - to the parts manufacturers), it is certain that people can not identify quality plastic by a visual inspection. My former company sold their top tier products to all the major automobile companies (for parts under the hood, in the cab, etc). When quality was off, they STILL sold the plastic that didn't meet the specifications. Parameters that were occasionally "off spec" were UV resistance, temperature resistance, polymer molecular weight and chain length, chain termination problems (can be important to avoid chemical attack), brittleness, creep resistance, fatigue resistance, etc. It wasn't simply that the color was off, although that happened also.

BTW - we had manufacturing facilities in Germany and Japan - as well as strategic partnerships with companies there.

Anyway, we all knew where this off-spec plastic went and that we would see it again in the automotive aftermarket (as one example. Cheap plastic and cheap elastomers are ways to keep parts cost down without ANYONE being able to identify the issue - until the part "dies an early death".

Now if a company were to have their parts manufactured overseas, but invested as much in the QA/QC process as the major automotive companies did (and still does), and implemented severe consequences for intentional cost cutting without testing/approval - then yes.... cheaper.quality parts from over seas is quite possible.


At least in the older days, Ford (and many other companies) was VERY good about holding suppliers accountable for delivering quality products.
Just something to consider.

 

I mainly had the same experience as Mark, except that some parts may have had specific formulations or attributes in the contract with Ford et al. and could not go into the aftermarket. But even at Ford, spec's dedicated if the parts went to the assembly line or the service (Motorcraft) side.

Based on our OE parts, yes. Based on my motor, not so much on the replacement side. Although this surprised me as our Motorcraft brake service parts still had a QC control above the typical aftermarket level.


Considering the identification marks were had to put on our products based on Ford's anti-conterfiet division, visual is not a good tell.

 

XDP sells a degas tank for $40.

XDP has one for forty bucks? I don't see it on their site. B.

At 50% of a Dorman, it's either a Dorman sold as a loss leader close to wholesale price, or some company making them for less than Dorman.

 

Well, the one I linked too has a non vented cap. Worthless. And they are not sure the factory Ford cap will work on it. Double trouble. and the threaded port on the bottom is an M10 1.5 metric thread, which could be tapped to 1/8" pipe. Triple threat. So the tank I linked is out. Seems back to factory plastic is the only way to go. B.

 

I would probably buy from AutoNation White Bear Lake before taking a chance on a discount one:
