2015 Hyundai Genesis 5.0 lower front timing cover replacement

Well, I just found that AISIN(Toyota part supplier) makes replace water pump replacements for the 5.0 engines. Therefore, I decided to add one more part to change to the list; the water pump. The OEM water pump is over $300 dollars, however I was able to pick up an AISIN brand water pump for about $60 on Amazon.

This is more like what I was expecting when I bought the Genesis; affordable part replacements on a nice luxury car. Now I am happy owning this car since I do not have to spend Mercedes like part prices on Hyundai OEM parts.:)

OEM water pump; hence why I did not swap it out at the time.

I finally got my oil cooler gasket set. I had to remove the oil cooler off the oil filter bracket to let the coolant and oil drain out from when I pull the cooler/oil filter assembly without draining the coolant from the engine block first.; which allowed the coolant and oil to mix in the cooler. I was able to drain the oil cooler of any(well most) fluid, but it required changing out the oil cooler coolant and oil gasket seals.

The oil cooler and gaskets. The upper inlet and out holes are for the coolant and the lower inlet out holes are for the engine oil. The oil filter/oil cooler assembly at the top with its gasket that separates both the coolant and oil ports for the cooler.

Good Deal - It's Japanese, it'll be fine.
 
Dang, that's so impressive. You can now build a Genesis 5.0 from scratch, probably using non Genesis specific parts. 👍
 
Looking to update and upgrade your Genesis luxury sport automobile? Look no further than right here in our own forum store - where orders are shipped immediately!

I hope so.

Toyota/Lexus water pumps does leak as an rule with high mileage; it is one of the brand Achille's heel next to timing cover leaks/weeping. However, Toyota water pumps tend not to leak until after 100k miles. So hopeful this water pump will last that long at the least.

LOL. Thank you.

I had practice over the years on GM and German models. The Genesis is actually very easy to repair as modern cars go with the proper tools. The only issue that slowed the repair down was OEM part back orders and lack of aftermarket parts as substitutes.
 
I hope so.

The one on my old 2005 Acura TL made it past 100k - dry as a bone. Replaced it though @ the timing belt service. My 5.0 still seems to be leak free @ 112K.

To be honest, my 5.0 water pump seem to be leak free as well with 90k miles. However, I always swap out the old water pumps when I remove them for repair work if possible. I had a bad experience long ago when I put an old water pump(with new gaskets) back on an engine I repaired and then it leaked a few months later through the weep hole, which meant taking the engine apart again to swap just the water pump.

The 5.0 engine has some beefy well made components for sure. The cost cutting for the 2015+ Genesis sedan was not in the engine and its components. Maybe the body and interior trim have some cheap parts, but not the drive-train and suspension parts.

Heck, the OEM Metal Dyne brand water pump that Hyundai uses on the 5.0 is maybe built better than the Aisin brand water pump. However, I am not spending over $300 on the OEM one to find out.

The Aisin water pump fits perfectly. The only difference was that it had slightly thicker alignment dowel pins than the old water pump that required a small rubber mallet to set in the holes.

My old water pump did have some back and forth movement in the pulley bearing, but it still rotate smooth overall. However, the new water pump bearing spins smooth and has no looseness in the bearing at all. My old pump would probably start making noise(and leak) at about 150k miles or so based on the bearing looseness at 90k miles, which is about normal for any engine.

Next is the AC compressor.

The old OEM(top) and and new Aisin(bottom) water pumps. Both are the same design and fitment. However, the Aisin cost $60 and the OEM cost $330.

Good deal - might as well do that stuff "while you're in there..."

Good to know - as mine will be around for at least another year. I'd like to turn it, but can't accept the interest rates at the moment.
 
I installed the AC compressor. It takes about 4oz of PAG46 oil. The service manual just states PAG oil(no oil weight) as well as the AC information plate on the hood. Gotta love Hyundai service detail information.:rolleyes:

However, the compressor info plate does mention a PAG46 oil as well as the Super Cool(PAG oil brand I used) website.

Compressor installed and PAG oil I used. I drained out about 4oz I suppose since I did not measure the exact amount when I first remove the compressor. I assume that when I let the oil drain out the ports when I first removed it I got about 3 1/2 oz out. I was only able to drain out about 1/2 oz when I pulled the compressor drain plug.

Next, I have to deal with the wiring harness and it many connectors, plus make sure that everything is routed correctly so that I can install the intake manifold. The engine is just about ready to started.

The PAG oil used for the compressor.

The AC compressor installed. Now, I just have to tackle the wiring harness and intake manifold.

Intake manifold and high pressure fuel pumps installed.

Man, the wire harness and hoses are a pain to sort out. But, it is sorted. Now I got to figure out where the darn wire harness and manifold bolts go. It seems that most of the gray 10mm bolts are for the wiring harness brackets and the black 10mm bolts are for parts attached to the top of the intake manifold or valve covers.

The intake manifold installed. Next, just sorting out the various bolts, brackets and hoses.

Looking Good!

Thank you.

I probably know how to tear apart and reassemble the 5.0 engine better than most of my local Hyundai dealership service techs.:)

However, I am sure that they would have figured it out like I did by reading the offical shop repair manual. Plus, they would not have a year to sort an engine repair for a customer like I did.

Think of all the labor $$$ that you've saved!

Correct.

I was quoted about $5000 by my local Hyundai dealership to replace my lower front timing cover. I may have spent about $1500( I think less exactly) for parts and tools needed to get the job done myself.

So, yes I saved a lot of money and learned about the engine at the same time. Still, not a fun project to under take.

Yup - No fun at all, but you added to the tool collection.

True.

Well, actually the only tools needed for this engine disassembly are 10mm,12mm,14mm,17mm and 19mm sockets and wrenches(hand and impact); basic tools really. Maybe a few large sockets for the crank pulley,etc. The Tau V8 is a very basic engine to tear down.

The expensive tools needed were related to the AC(recovery machine and pump) and supporting/lifting the sub-frame(platform jacks).
 
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.
