2015 Hyundai Genesis 5.0 lower front timing cover replacement

[skipgen]

Man, I am finally nearly ready to start my engine. I am finishing up the AC system. I got everything button down, but I need to change the desiccant filter pack in the front condenser in front of the radiator. The desiccant pack needs to be changed when the AC system has been opened to air. I am waiting for a OEM replacement and then I can pull a vaccum to recharge the AC system.

The desiccant pack is located on the passenger side of the condenser inside a chamber sealed with a 10mm hex cap filter. The desiccant pack is basically a larger version of the smaller packs located in shipping boxes and food packages that absorbs air and moisture.

The AC system reinstalled; except for the desiccant pack.

The desiccant pack in the condenser. You have to use some long tipped needle nose pliers to pull it out the chamber.

The desiccant pack and filter cap with the needle nose pliers I used to pull it out.

Great Progress - Fingers crossed that it continues to go well.

Thank you.

So far so good. I just have to focus on the details type of stuff now like the AC. Then I will post how to properly bleed and fill the coolant system; which can be tricky on newer cars like the Genesis.

I ended up doing the coolant refill first due to having to start the engine to top off the AC system(run the compressor). I used an OEM brand coolant vacuum fill tool that uses a shop air compressor to pull a vacuum and then fill the coolant system. The $50 tool works well. I only had to manually top off the radiator.

I used about 2 gallons of coolant, but it may take another gallon to fully top off the system when the engine is running at operating temperature and the heater turned on. The tool filled up the system is less that a couple minutes. I will start the engine for the first time in a year when I add engine oil and then top of the AC system. This project is nearly done.

The tool I used. It fits on top of the radiator opening. I pulled a -24psi vacuum and let it sit for a few minutes to checks for any leaks before I added the coolant. If the gauges loses vacuum then it means a leak in the coolant system. My system held-24 psi the whole time. To fill the system you open the fill valve an let the vacuum suck in the coolant from the jug until the gauge reads 0, and then top off. The process usually fills the coolant system without creating air pockets.

Good to see the progress!

That's quite a handy tool.

Yes, finally!!!

The tool does the job well. Almost too well since it just sucks a gallon jug dry in about 20 seconds; so you have to be ready to close the valve quickly to prevent the tool from pulling air from an empty jub.

DARN, DARN,DARN!!!!!

My AC system will not hold a vacuum, but I know why. The o-rings. I replaced all the old o-rings on the AC lines with green o-rings from a HVAC kit I had around the garage, but most was not the same thickness as the OEM o-rings. I gave it a shot hoping that they would still seal up to prevent buying expensive OEM o-rings. They did not. So I have to wait yet again for Hyundai to ship me the proper AC o-rings that would be special sizes not in my kit.

The Genesis uniqueness can be annoying when it comes to aftermarket parts since most do not fit it; like simple o-rings.

Ugh. Sorry to hear that.

Heck, I can still drive the car without AC I guess, but I really do not want to risk running the AC compressor dry. It is a very expensive variable speed compressor.

It is not the end of the world, but I assume that I will have to wait about a week for the OEM specific green HVAC o-rings to arrive by mail. I have already removed the o-rings from the lines; which is still pretty easy to do with the wheel liner and most of the engine bay trim still removed. Hyundai did a good job of keeping the ac lines really easy to access and remove.

I just removed all the aftermarket o-rings since I do not know which ones sealed or not and left the AC lines mocked up in place until the proper OEM o-rings arrive. I should just ordered the OEM o-rings in the first place instead of trying save some money. The stock o-rings are much thicker than the aftermarket o-rings I used.

The thinner aftermarket AC o-rings that did not seal.

Delays, Delays....

 

[carguy75]

Delays, Delays....

Yes, but it is my fault mostly.

I should pre-ordered all of the parts that I needed at one time like a dealer service center would have done. Usually all rubber seals needs to replaced when removing a part with o-rings or gaskets, so I should have just ordered the parts needed before hand even though I will be paying 3x as much for one o-ring at the dealer or online OEM part shop.

However, i must also admit that the 5.0 engine has many parts that needed to be removed and a lot of parts that needed to be replaced due to age which were hard to get to and obtain. Many are dealer only parts and a few I just recently discovered can be found aftermarket.

I was hoping that the properly sized green AC line o-rings were in a 420 piece set of HVAC o rings I had already on hand, but no.I tried to use them and it did not work out.

This not a easy repair and I cannot just run to my local Autozone for many of the parts that the Genesis 5.0 engine will need if an issue occurs. I have to order most of the parts and wait for them to be shipped either online or at my local Hyundai dealership since the 5.0 engine uses a lot of one-off parts that are not in stock.

So yes, delays will occur when you are forced to rely on Hyundai to supply you with parts for the 5.0 TAU V8 engine due to it being an one off engine without out much aftermarket support to help.

 

[skipgen]

Yeah. That is true.... Hopefully, my 5.0 will last long enough for interest rates to come down to sanity. Although, to be truthful it has been pretty reliable except for the various well known external rubber bits perishing.

 

[carguy75]

LOL. I am still waiting for the o-rings to arrive by mail from Hyundai. I believe that the dealership service centers get priority on part shipments before residential(or online store) orders at the main shipping center.

 

[carguy75]

Still waiting for the o-rings. However, the desiccant pack and cap I reordered at the same time just arrived.

You must use a new desiccate pack every time you let one sit in the open air for more than a hour.

I hope these o-rings are not on a month long waiting list or backorder.

That just sucks... Amazing that .50 cents worth of parts can bring the whole works to a halt!

Tell me about it.

I give Hyundai an "A" for overall design and ease of serviceability of the 2015 Genesis 5.0, but an "F" for parts availability. My local Hyundai dealership do not even have many of the parts I need in stock and have to order them as well. the dealership parts guy claims the Genesis 5.0 is a special luxury model that they do not repair often enough to stock parts for it in-house.

To make matters worst the local dealer prices are more than the online Hyundai store prices. So I just order my own parts since it will take the same amount of time to receive the parts it seems either way. Plus, I feel that I would paying my local dealership an inflated price on the parts that comes from the same warehouse.

 

[carguy75]

Still waiting on some darn o-rings from the Hyundai warehouse. This is one of the reasons that this repair is taking so darn long.

Frustrating.
