Oil change info 3.8 V6 in pics

ntx_v8 · Nov 30, 2014

I changed my oil and inspected my air filter on my 3.8L V6. Due to the bottom fairings, it is somewhat of a pain, but probably easier and definitely neater than my 2010 V8.

My tool set is:
27mm socket.
17mm socket.
10mm socket.
3/8 Rachet and 1/2 adapter for my 27 mm socket.
Phillips bit or screwdriver.
o-ring pick (nice to have).
M18 fuel driver (there are a lot of screws, so really nice to have).
Rag.
Drain pan
Ramps

The basic procedure is:
Drive/Raise vehicle onto ramps.
Remove front fairing
Remove rear fairing
Remove drain plug and drain oil pan
Replace drain plug (and drain plug gasket if desired)
Remove filter housing and let drain
Replace filter and filter housing o-ring. (Coat new o-ring with clean oil before installing).
Replace rear fairing
Replace front fairing
Reset service interval on Driver's Information System
Record Maintainence in Maintainence Log.

If it weren't for the 5,000 fasteners for the 2 fairings, it would be on the easy side of oil changes. (If my aunt . . ., she would be my uncle).

I am considering cutting a large access hole for the drain plug into the rear fairing. Would simplify the job a fair bit. I haven't figured out how I will cover the hole (thus retaining the aerodynamics that Hyundai seems to covet) yet.

I can post 10 pictures per post, so I will post several replies with the rest of the pictures.

I probably got carried away, but . . .

Sorry for the length.

Nice write up. One tip i heard someone here mention, is take off the rear fairing first. Remove the rear fasteners from the front fairing and the rear fairing will be held in place by the pop nut at the rear and the rear edge of the front fairing at the front. I used this this technique on my last oil change and it worked great. It makes reassembly easier too. Put the front fairing on first but leave the rear fasteners off until the rear fairing goes on.

Also, on my last oil change, i had originally planned to change the oil filter without removing the front fairing, but i couldn't get the filter housing moving without a 27mm socket and all mine are deep sockets so i put a 27mm oil filter socket on my wish list.

That and a mighty vac should allow me to do the changes without dropping either of the fairings. A Chinese food takeout container (black plastic) fit perfectly to catch the oil from the housing.

Keep us informed when you successfully do that.

I will do. I should have explained the 27mm deep socket wouldn't clear the fairing to fit on the filter housing.

You gotta love that huge space in front of the V6.

So does this mean the car can't be taken to Jiffy Lube? Looks like to many plastic rivets and stuff.

Thanks for the very detailed writeup, NTX. I've been doing my own oil changes, brakes and most other car maintenance for years, so it's great to learn how best to take care of our cars. I've never owned a Mityvac, but this thread has convinced me to go out and get one. Having to remove both the front and rear undercarriage fairings/shrouds doubles the time for what should be a 20min job! With the Mityvac, at least you only have to remove the front portion to have access to the filter, and it appears we may be even able to avoid that with a shallow 27mm socket, doing everything from up top. Will have to check that out. Anyway, thanks again. BTW, where is the best place online to purchase OEM Hyundai oil filters? Also, are there any WIX or other decent alternatives to our part no. 26320-3CKB0 oil filter? Thanks in advance!

I haven't found a Fram/Wix/etc. part number. I negotiated parts at fleet rate when I bought my car, so my dealer is where I go for now.

If you don't have to use a jack to lift the car-and have some sort of power driver for the 10mm socket, 30 minutes will probably do it. I'm still thinking about how to put a sturdy, cheap, easy to remove access cover in the rear fairing for the drain plug/oil flow.

But I don't think you will go wrong with a top side job---if you can reach down to the filter area without trouble.

If you get a MityVac oil extractor, make sure you get the MV7300 PneumatiVac. You will need to hook it up to an air compressor (a small electric compressor will do fine). The ones with hand pumps do not work well, unless you are OK with getting out only 80-90% of the oil.

You should get the Hyundai OEM filter. You can purchase them from some dealers who sell them online, such as http://www.jimellishyundaiparts.com. If you purchase a bunch of oil filters, air filters, and cabin filters all that the same time, the shipping cost is not a concern.

I have a small, wall-mounted Campbell Hausfeld air compressor so that should work fine. I"ll check out the web site and see how prices compare with a couple other sites I found. Thanks for the tips guys!

Mark_888 · Dec 3, 2014

Any small electric air compressor will work fine. Here is one for $40.00 (sale price through the end of today):

I just changed the oil on my 2012 3.8 genesis sedan with 30k miles. I did not have a 27 mm socket, same as a 1-1/16 inch socket. I tired an ajustabe wrench but it did not work properly, turned on the plastic hex. I used a small oil filter strap wrench below the hex and it did the trick. I don't think my oil filter had been changed for a while so I needed a lot of torque. The strap wrench put the torque closer to the threads. Perhaps you won't need a new socket.

Are you serious? The 27mm socket above costs $7.00.

MidnightSun had some good points the other day that I am copying the highlights to here. His full post is at http://genesisowners.com/hyundai-genesis-forum/showthread.php?t=17511.

The panel inserts (plastic ones) will become almost unusable once taken out so do pick up a bag of 100 or so on eBay and keep in your trunk. http://www.ebay.com/itm/Black-Plast...ash=item566e964550:g:eVYAAOSw9N1Vi50O&vxp=mtr

Secondly, the 10mm head bolts holding the balance of the panel in place tend to rust up/jam tight. I sheared off 4 of them and I was very careful. Dunked the remainder in grease and inserted those. Worked half the day drilling out an retapping the frozen ones. What a pita.

The plastic panel inserts don't break a lot, but they do get difficult to re-install. It is a choice about how much time you want to spend installing splayed ones.

Midnightsun uses grease to reduce corrosion, and I started use WD-40 on my 4th oil change today. I live in salt-free Texas, and was already seeing minor rust after only 13 months.

Is the 27 mm socket required for the 3.8L or the 5.0L (mine) or what?

I think I take a 24 mm. - not sure.

Haven't done the job yet - looks like a lot of fun.

27mm for G1. I don't know about G2.
