2015 Hyundai Genesis 5.0 lower front timing cover replacement

[carguy75]

I don't do a lot of major work on cars anymore - but I would like to be able to see what's going on in the various systems & maybe be able to reset things here and there before I "Repair by Check"...

The D8 does go deep into the ECU to pull even old codes stored in history. I was able to see what exactly went wrong over the years with the 2015 Lexus I bought recently. It reported that the Lexus had a bad power door switch and camshaft sensor at one point. Both of the issues has been resolved.

The scan tool is must have for any DIY that work on newer cars or for someone who buys used cars often because you can get a good history of what went wrong with it over the years. The bonus for used car buyers is that you can unlearn all the smart keys and just add the keys you have in your possession; especially if you buy a car from a seller that is questionable and only claim to have one key to offer you. Lexus charge about $500-$700 to do that for you if you want a new smart key.

Let us know how it works on your Hyundai.

I will post if the D8 works on the 2015 Genesis or not. I will probably need to recalibrate some modules(sunroof, power windows,etc) since my car has been without power for months now. Hopeful I can just calibrate the modules with the D8 scan tool.

I finally installed the used lower timing cover. I tried to wait for a new lower timing cover to stop being on back-order, but it seems like it will be on back order until January 2023 from what my local Hyundai dealer part department clerk told me. The part department clerk wants me to pay $700 up-front and wait for the part to be shipped in January 2023. If the part comes damaged; then I will have to wait until another part becomes available.

So I just installed the used lower timing cover from a 5.0 Equus I ordered off Ebay and will just trade in the Genesis when it is road ready. I used Permatex Ultra black RTV and new seals(crank and rubber gaskets). I would post more pics and detailed information, but it do not seem that many members on this forum will ever repair their own 5.0 engine to go through the effort.


The lower timing cover installed. Next will be the upper and lower oil pan install.

Good to know that there is parts commonality between the various 5.0 engines - at least for major castings.

It was kind of a dick move that they wanted you to pay for that part upfront. That would leave a bad taste in my mouth as well. A lot of Genesis parts have skyrocketed in cost (if you can find them). I remember when not long ago a trans pan was $120 all day long - now they're 4X as much... The gouging has gotten quite out of control.

Thank goodness for some part compatibility with the 5.0 models.

I am lucky to even have found the used 2015 Hyundai Equus lower timing cover. The 5.0 lower timing cover is a rare part to find outside of buying a whole engine; new or used. The KIA 5.0(K900) engine upper oil pan is different; so that timing cover may not work either.

Parts(engine,suspension,or trim) for a 5.0 Genesis costs nearly the same as its Japanese(Lexus) or German(Mercedes) competitors; if the parts can even be obtained. Hence why I will be trading the car when I repair it. A used high mileage Genesis 5.0 is not any cheaper to repair than a well known luxury brand like Lexus, so I am just going to buy a used Lexus.

Yes, I know that Lexus engines can fail as well, but the Toyota 3.5 V6 is easy to repair and has many parts avaible since Toyota put that engine in nearly all of their cars. I will miss the Genesis 5.0 power, but not enough to deal with Hyundai shortcomings(poorly written service manual and part scarcity/price)out of warranty.

Yup - things are tough all over... I never intended to keep my 5.0 past 100K. Indeed, I almost never keep anything much past that mark - except the 2006 Acura TL that had 110K. Just had the mandatory timing belt/water pump service done & was in perfect shape inside & out until I was t-boned at an intersection. That was a great car. I'm fully convinced it would still be running perfectly to this day. I was actually thinking about replacing my 2015 5.0 Ultimate with a 2018 5.0 Ultimate that has 60K less miles and has the 360 cameras and built in CarPlay. However, the Pandemic/Supply Chain Markup on everything has put that upgrade path on hold - @ between $32 - $35K , they're about $7K or so above what they should be.

Lexi are pretty indestructible as well, I just never got on board with them. Always found the affordable ones a bit bland for my tastes...

To my Genesis' credit, it has been much more reliable than the Infiniti G35s that proceeded it. By the same mileage (~105K) the Infiniti had devoured an A/C compressor, alternator, water pump, 1 pair cam position sensors, 1 pair of throttle bodies and the LSD was beginning to grumble. And to add insult to injury the dash pad was in it's initial stages of reverting back into the primary petrochemicals the spawned it. The Genesis has only eaten an alternator. It does have a couple of issues - a malfunctioning parking sensor and I have to replace the worm gear in my driver's folding mirror.

Too bad someone can't 3-D print something like that easily and cheaply (with the necessary level of durability)...

To be honest; I would keep the Genesis 5.0 if the parts needed were available and not so expensive. However, I did have an bad experience with the oil pressure sensor that educated me that this car can be a problem to own after 100k miles.


I am starting to like "bland" cars now like a Lexus GS350 F-sport or even a 2017 or newer Lexus ES F-sport. I do not even race around town like I used to; so no need for any more V8 powered sedans.

The F-sports might be interesting. I was given an ES350 to drive when the Infiniti was in the shop (while dealer fixed the Infiniti A/C)... It was like a Japanese Town Car. The infotainment system was a hot mess. Sure did have nice paint & leather though!

A 2017 or newer ES f-sport or GS f-sport will be good enough for my commutes. I am beyond needing a sedan that can do 0-60 in less than 5 seconds and can carve corners on a track.

Lol. If I tried "carving corners" w/ my 5.0, I'd have to mount training wheels on the door handles! She's a big 'ol tub... I could live w/a IS or GS, at least they're RWD.

I just like having the 5.0 thrust to merge safely onto Texas freeways - Here, I follow the fighter pilot's mantra "Speed is Life".

I will mostly likely buy a GS model. It is quick enough for me. I just want a nice luxury car that is easy to maintain after 100k miles. It seems like Lexus is the only luxury company that have engines that can run well after 100k miles without much drama. Lexus tech is dated, but is reliable. Many newer cars from other automakers have nicer tech, but also a high rate of failures that can be costly outside of the warranty period for radio replacements.

I only buy used luxury cars; so most will already have about 50k miles or more when I buy them. Lexus seems the be the best way to go for used luxury cars if long-term reliability is the goal.

I assumed that my 2015 Hyundai Genesis would be cheaper to repair than a Lexus or Mercedes; it is not. Hence why I am moving on.

I get you - I don't generally buy new lux cars either. I do agree that there are some common Genesis problems that would be non issues for Lexus or Acura. Still. I'd rather have a 7 year old Genesis that a 7 year old BMW....

I agree; hence why I never purchased a BMW.

I like BMW styling, but the cars seem to fall a part by 70k miles. Most used ones I have seen have peeling control buttons and look like crap by 100k miles. I am not even going to go into the engine problems that BMW have. Hence why I am just going with Lexus for now on.

I still like my Genesis to be honest, but I am worried about the transmission and other big item repairs since I will never find a replacement in less than 6 months; even new. Atleast I can always buy Lexus(Toyota) parts(new or used) and Toyota provide properly written service manuals.

I forgot to show how a proper RTV bead should look when applying it to the timing cover. You should apply an 2-3mm bead of on RTV to inside edge of the timing cover and around the center bolt holes.

The RTV should be visible on the inside where the cover meets the engine block for a good seal, but not so much that it drips and hangs.

Here is the RTV seal I made that is similar to the OEM application. The timing cover is sealed up nicely. I will scrap away some of the excess, but overall a good solid bead line.

Crap!!! I have seen a few black 2015-2020 Genesis or G80 on the road lately. I must say that the car is still sexy looking. I have reconsidered trading in my ride when I am finished working on it. I will just keep it up; even if I have to wait for the replacement part supply to stabilize. Hopefully, I will not need any other major components that are on back order.

Plus, I have read that Toyota(Lexus) also have some issues with back ordered parts as well. I also have to consider that I will still have to pay about $20k-$40k to find a good low mileage Lexus replacement; which means a new car note. The Genny is paid for.

I guess it is really cheaper to keep her.

 

[JEBIV]

for sure cheaper to keep her

As a friend of mine says - "Cheaper to fix what you've got". You might as well keep it & enjoy the fruits of your labors!

I was going to upgrade to a newer model, but the constant interest rate hikes are giving me pause...

LOL. I was just about to install my upper oil pan until I realize that I will need to clean the cylinder heads for the upper timing covers. The problem would have been that the old RTV could have fell into the upper oil with no way to clean it out without pulling the pan again.

If I clean the cylinder heads first then most of the old RTV would just fall out the bottom of the lower timing cover; especially if I use compressed air. Therefore, I will clean and install the upper timing covers before installing the upper oil pan.

I will take pictures of the RTV bead I will lay this time before installing the upper timing covers.

My upper timing covers that need to be cleaned and installed.
