Coolant Hose Is No Longer Being Manufactured

[StarPower]

It appears that at least one of the coolant hoses for our engines is no longer being manufactured. This affects the 2015 V8, but I am not sure which other engine options or years are affected. My car has been at the dealership for over a week while they tried to order a coolant hose. Based on my memory from a phone call, the hose runs under the intake to an oil cooler (I'll try to get more detail later). The service advisor informed me that the company in S. Korea that makes the hose has stopped manufacturing them and there is currently no other supplier or aftermarket alternative. They are still looking for a hose and will get back to me if they can find one. If they cannot obtain a hose, I'll probably contact HMA for a resolution. Has anybody else encountered a similar problem or do you have any suggestions on a path forward? Thank you.

I see two solutions.
1. Scrap the car as infixable
2. Use some ingenuity and piece together a hose using a different flexible hose, copper tubing, clamps, etc.

Sure won't look pretty but can work. Over the uears I've seen some hack jobs for hydraulics, cooling, drains, but they worked.

Another option I did not mention, repair the existing hose. What is werong with it? I once repaired a heater hose by cutting it apart where it leaked, inserted a piece of tubing, clamped it. Held for a couple of years until I sold the car.

Owners may have to use aftermarket coolant hoses and modify them to fit the Genesis set up.

The dealership will not make modifications using aftermarket parts unless a TSB specifically calls for it; so they may wait until a proper hose becomes available in the parts warehouse.


Parts availability is the main issue I have with the 5.0 Genesis models. My 2015 Genesis have been sitting for nearly a year while i wait on OEM parts to ship or become available. To be honest; some of the wait time has been me putting off the repair, but waiting on parts was a big part of the delay as well.

It seems like you will have to just wait until the dealership finds the correct part, unless you do the repair yourself.

Note: The engine oil cooler on the 5.0 do not have any hoses attached to it. The oil cooler is secured to the lower front timing cover with a gasket and bolts.

Thanks for your responses. The dealership mentioned oil cooler, but I it's possible they might have meant the transmission cooler. I'm hoping I can see the hose and get a part number so I can confirm which hose it is, how badly it's damaged, and the cause of the damage. Once I know which hose it is, I have a couple of options. I can look into later years to see if the hoses are similar and can be modified to fit. I've also looked into aftermarket hoses. Even if they don't make the exact part for our car, companies like Gates have a huge catalog of hoses and may have something similar. If not, auto parts stores have generic hose parts that I might be able to use to build something that'll work. I have also seen hose repair kits at most auto parts stores (essentially hard tubing and clamps like EdP suggested). However, if the hose is deteriorated due to chemical degradation along its entire length I worry that it may fail completely if I try to repair it. I'll post an update once I know more.

Is the hose one of these? They are all shown as in stock. Will the dealership install a hose that you bring them?

They should do it if it comes in "Hyundai" packaging...

This parts problem + the constant tire BS (I've lost 2 fronts due to potholes + they only last 20K miles) is really, really making me think I should dump my 2015 5.0 and get a charger with the 5.7.

 

[StarPower]

The tech showed me the part that's leaking, and it is a plastic connector at the back of the engine under the inlet manifold where the hose to the transmission oil cooler connects. The connector is only available as an assembly with the hose. The part numbers on the estimate are 25420-B1600 (hose assembly-oil) and 28312-3F000 (seal-etc). Both parts appear to be in stock at several online parts retailers. However, the several of the retailers state that they don't stock all parts and may need to order them from a Hyundai distribution center. The dealership said they checked several places and they initially gave me an estimated delivery date, so it's possible that some of the websites show an estimated ship date even if the part is not in stock.

I've found parts online even when a mechanic swears there's none to be had. You can always ask, "If I find it will you install it?" - all they can say is no.

Thank you all for your replies. I apologize for not replying for so long; I've been busy at work and didn't have any news until now. My dealership called yesterday to say that the part was available and would be delivered soon. I hope this means that Hyundai has contracted with another manufacturer to start making the part again, but I can verify the next time I talk to them.

The dealership has been very helpful. They have been providing a service loaner while awaiting the part, so at least I haven't been paying for a rental. They also stated that they would install a part if I could find one. I checked with a few salvage yards, but none of them had it when I called.

I also looked into fabricating the part, but this would have been the absolute last resort. High temperature 3D printing necessary for the types of plastic that can handle the temperatures in the coolant system is expensive, and there's no guarantee that the part would hold up to the temperature changes, stresses, chemical attack from the coolant, etc.

UUGGGHhH I just got 2 flats from potholes in the last 2 weeks. Now I need struts and I can't figure out if they are dampening or not.

May I know what part that is? Is it 25485-3F400, which is just the connector itself? May seem that Hyundai may have decided to get just the connector manufactured again under a separate part # as older 5.0 owners such as ourselves are starting to see this (manifold?) wear out and crack from years of heating and cooling the engine. It's also much less expensive ($14.71 MSRP) than ordering the entire assembly itself (~$170).

I know the hose assembly (25420-B1600) has been on national backorder for awhile but it seems like the connector itself is available as a separate part. Per the tech diagnosis, "Rear Engine Coolant Pipe Assembly is cracked and is leaking coolant" so it may just be this part.

I'm not able to edit my last post but I just wanted to share an update about this part that ended up resolving the coolant hose leak issue on my 2015 5.0 that I posted on this other thread with the same problem that other 5.0 owners may find helpful: Engine Temperature Sensor(s)?

I just went through this problem and two weeks ago after waiting 2 month on a waiting list the part on day just showed up at the dealership. I cost me $224. Not 175 don’t know why but after months of waiting and calling it just showed up unannounced . I spent over a 1000 dollars when all was said and done to replace a plastic distribution bock that had literally disintegrated by an electroless problem created by the manufacture using non compatible materials . I literally receive no support from Hyundai Corperate customer service. I had an open case they were completely useless and uninformed waste of time. They couldn’t even call me back when told me THEY WOULD. MY CASE MAANGER NEVER EVEN EMAILED ME AFTER I SENT HER INFORMATION.
We owner should file a class action law suite.the part would have been covered under the 3 year 50,000 mile warranty but not the 100,000 Mile/ 10 year power train warranty. My opinion is ther should have replace the entire engine under my power train warranty.

 

[StarPower]

I'm glad the part finally showed up, even if you had to wait. The last word from my dealership was that Hyundai has contracted with another manufacturer to make the part, but it could still be a while before they start manufacturing them.

alnn: Thanks for posting the part number for the plastic connector above! Some of the online retailers show that it fits my VIN. I'll also ask my dealer if that's the only piece that's broken on mine.

I hear and understand your frustration, but hoses and connectors are not covered by most power-train warranties regardless of automaker. Hence why it is very important to pick your used car to buy wisely or even a new car if you are going to keep it pass the bumper-to-bumper warranty period; since most modern cars uses plastic connectors on coolant and transmission connectors which fail pretty often after 60k miles or so.

Just ask some BMW owners the problem plastic hose connectors causes them with out-of-pocket repairs.

 

[StarPower]

I finally got my car back. I can confirm that the plastic connector is available under part number 25485-B1600. I do not believe that Hyundai never informed the dealerships who had the assembly on order that the plastic connector is now available as an individual part. My service advisor said that he would mention this when he explained why he billed over $4,000 to Hyundai to pay for a service loaner for over four months.
