Coming up on 60K and coolant change on maintenance schedule.
Any advice on flushing these NU engines? Is the Hyundai coolant best bet while under warranty? Otherwise what is the best coolant for this car? I'm just getting started on looking into this and I always like to post here to get feedback. Thanks.
 
I would get the factory coolant. Get 5 or 6 gallons of DISTILLED water to flush through the system and fill back up with coolant/distilled water "usually" a 50/50 mix.

Refilling And Bleeding



Never remove the radiator cap when the engine is hot. Serious scalding could be caused by hot fluid under high pressure escaping from the radiator.



When pouring engine coolant, be sure to shut the relay box lid and not to let coolant spill on the electrical parts or the paint. If any coolant spills, rinse it off immediately.
1. Make sure the engine and radiator are cool to the touch.
2. Remove radiator cap (A).


3. Remove the under cover. (Refer to Engine and transaxle assembly in this group)
4. Loosen the drain plug (A) and drain the coolant.


5. Tighten the radiator drain plug securely.
6. After draining engine coolant in the reservoir tank, clean the tank.
7. Fill the radiator with water through the radiator cap and tighten the cap.



To most effectively bleed the air, pour the water slowly and press on the upper/lower radiator hoses.

8. Start the engine and allow to come to normal operating temperature. Wait for the cooling fans to turn on several times. Accelerate the engine to aid in purging trapped air. Shut engine off.
9. Wait until the engine is cool.
10. Repeat step 1 to 9 until the drained water runs clear.
11. Fill fluid mixture with coolant and water (55~60%) (except for North America, Europe and China: 45~50%) slowly through the radiator cap. Push the upper/lower hoses of the radiator so as bleed air easily.


• Use only genuine antifreeze/coolant.
• For best corrosion protection, the coolant concentration must be maintained year-round at 55% (except for North America, Europe and China: 45%) minimum.
Coolant concentrations less than 55% (except for North America, Europe and China: 45%) may not provide sufficient protection against corrosion or freezing.
• Coolant concentrations greater then 60% will impair cooling efficiency and are not recommended.



• Do not mix different brands of antifreeze/coolants.
• Do not use additional rust inhibitors or antirust products; they may not be compatible with the coolant.


12. Start the engine and run until coolant circulates.When the cooling fan operates and coolant circulates, refill coolant through the radiator cap.
13. Repeat step 12 until the cooling fan 3 ~ 5 times and bleed air sufficiently out of the cooling system.
14. Install the radiator cap and fill the reservoir tank to the "MAX" (or "FULL") line with coolant.
15. Run the vehicle under idle until the cooling fan operates 2 ~ 3 times.
16. Stop the engine and wait coolant gets cool.
17. Repeat step 11 to 16 until the coolant level doesn't fall any more, bleed air out of the cooling system.



It takes time to bleed out all the air in the cooling system. Refill coolant when coolant gets cool completely, then recheck the coolant level in the reservoir tank for 2~3 days after replacing coolant.

Coolant capacity:
5.9 ~ 6.3 L (1.56 ~ 1.66 U.S.gal., 6.23 ~ 6.66 U.S.qt., 5.19 ~ 5.54 lmp.qt.)

Good call, forgot about that, cheap purchase too.
 
Factory fill coolant is a long life coolant and should last for 210000kms or 120 months as per the service schedule.
 
Wow, the hyundai maintenance schedule says 60k. Seems short for a 2012 vehicle.

I'd just go to the dealer and buy some pre-mix, drain and refil the radiator and repeat a week or month later (whatever's convinient) and call it good until the next time its due.

No need to flush at 60k when you know what type of coolant is in there and the service history of the car.

Most Asian coolants are now only sold in premix, though Hyundai may be an exception.

There's no reason to flush a cooling system that has had drain/refills at the specified intervals, IMO.
 
Okay so the consensus is that for the 60K maintenance I need only drain and refill the radiator. P-hoat is the required fluid in whatever way I get it. Thanks.
 
I called a few Ford dealerships today and two readily answered that yes they sell MC Speciality Green, both for $27.95/gal., a few others wanted to know the year and model car I wanted the fluid for, "we carry several" or something like that was the line.
A local Hyundai dealer sells Hyundai concentrated coolant for $21.95/gal. They only sell one Hyundai coolant for all years and models. Does that sound right? I questioned this and the parts guy went to check with the service dept. and confirmed that there is only one Hyundai coolant available. Should I get specs on this or not worry about it if I go that route?
 
That is correct. The hyundai stuff is all years makes for hyundai. If that price is for the 100%, I would jump on it!!!

I will have to check my hyundai dealer now to compare prices as I have been using the Greeen specialty formula from ford. Ford uses this stuff in their mazda made engines.

I stopped and bought 2 gal. of coolant at Ciocca Hyundai in Quakertown, PA tonight and they charged me $19.95/gal for the straight coolant. They have a link to their ebay stuff on their web site and you can find some good deals if it's stuff you need. Thanks for the help.
 
Yeah it's a grind, 80 mile commute each way to work. I got it in June 2011, one of the first 2012 models, took awhile to get a manual transmission. I'm happy with it for my needs, at 45.7 mpg with every tank recorded, obviously mostly highway miles. And I'm waiting on my $200 credit card for misstated mpg claims.
 
I haven't checked the requirements of my 2013's, but my older Hyundai's I've had in past, a 2002 Santa Fe, 2006 & 2008 Sonata all said "Ethylene Glycol Based Coolant" in the manuals. So when I flushed them I used standard Green antifreeze. Never had issues with any of them.

Nice mileage, you are one of the lucky ones as some people with long commutes were reporting 35mpg highway.

I bought my car in June 2011 and it gets 37mpg rather than the 40mpg stated, but I can reach 40mpg if I hyper mile it.
 
I would double check what kind of coolant it uses. It may have changed by 2012, but my 2008 Accent uses bog-standard green coolant, hence the shorter change interval. I think Hyundai is one of the last if not THE last mfr to switch to some long life coolant they can charge body parts for.
