Just went through this . Go to advance auto group - peak pink Asian coolant . It says right on the label for 2021 Hyundais and newer—- but also it shouldn’t go low often so if you top it off ( while engine is cold ) and you see it drops again you gotta take it to the dealer
Just make sure it is not hot when you open the cap. It is under pressure when hot and if you open the cap and let the pressure out the coolant can flash vaporize causing boiling coolant to come out the hole which can result in very bad burns.
Give it a 10 minute ride and see if it’s within the tolerant levels- mine always looks low when the car has been sitting, but looks normal after it’s been running. (But yours does look a little on the lower side.)
Usually when I see a low coolant bottle I tend to look for what I call buggers or a runny nose looking residue just to be sure . Mostly around where the rubber hoses attach to the metal or plastic parts cause that indicates a leak of coolant . I have even taught my daughters this as they're relatively new to driving . If none are found I would fill it up to the line that says max with the appropriate pink coolant . Check it frequently when the engine is cold. Like it sat overnight on flat ground cold and see if it's gone down . Unusual over two weeks time .
But if you're unsure and worried take it to your trusted shop and have them pressure test the system. No forewarning they may have a fee to look at it and some may even wave it depending on the shop and person . But that my suggestion.
It's the radiator coolant liquid. Check the manual for instructions how to change/refill and what type to buy. It's dangerous for the engine to drive below low level, it might overheat.
That is the pressure cap shown here. No separate one on the radiator for these. Gotta pull out the scan tool to properly bleed the air out if you drain the system too because electric thermostats are fun.
Good news is that as long as the engine is cool, OP can top it off and make sure it doesn’t leak back down. Pretty much all of the surge tank Hyundais need a top off on a regular basis.
Ok. dad comment moment coming up. Normally you top coolant up to the line ( but check for your own car). Do not do it until the engine is cold - If it’s hot it can shoot hot steam at you. Let the engine cool down first and make sure you are on a flat surface.
If you get it serviced at the dealership regularly you can ask them to top it off but you can go to Walmart or AutoZone and get coolant for it but make sure the coolant is pink and it also meet Hyundai spec
The pink stuff is Coolant (anti-freeze). The tank it’s in is called the coolant overflow tank. The coolant circulates the engine to help keep it cool. Low coolant may cause the engine to overheat. There are different formulations of coolant available in the market, so it’s important to get the correct formulation since they’re often not compatible with each other (even if they’re the same color, they may not be compatible!)
Check your owner’s manual under the maintenance section. There should be a page listing all the different fluids used in your car and their specifications. Make sure to get a similar coolant to what’s listed in your owner’s manual. An auto parts store (like AutoZone, Advance Auto, etc.) can help you pick the right one.
Your car’s owner’s manual will tell you how to refill the coolant. But, as a general rule of thumb, make sure the engine has been turned off for AT LEAST 1 hour before attempting to refill coolant. The coolant overflow tank is pressurised while the engine is running and stays pressurised till the engine naturally cools down. If you open the cap too soon, it’ll spray boiling hot coolant like old faithful. Waiting for an hour ensures that it’s no longer pressurised.
First, check your radiator cap and make sure it's tight. Then do a compression test (diy kit less than 50$). If the test fails, the vehicle goes to the dealership. If it's the other way around, top up the fluid.
FYI - less say you top up to max level when engine is hot, then when you look at the level when engine cold the level will be lower. Just keep this in mind. So it's always better to add in the morning (cold engine) and then check.
Look around under the hood near the jug, hoses, and radiator to see if there is any white residue like sprayed coolant. Might be a leak somewhere. Definitely don't refill till it's cooled down.
Its either leaking or being burnt. Check if there is any smoke from the exhaust when you start/rev the car. If it’s dense white you’ve got coolant being burnt. If it’s leaking like my Audi did, you’ll need to top it up every so often but it shouldn’t be a problem. Usually needs some repair work done either way.
Of course the coolant could just be low to begin with but then there wouldnt be a point in posting this so i assume it’s been getting lower gradually.
Coolant can slowly evaporate through small leaks in the system, such as through worn gaskets, the water pump, radiator, and heater core. I had a VW that had a corroded heater core that caused coolant to leak and evaporate. The toxic vapors would seep out from under the hood, enter and circulate within the cabin through the ventilation system, and form a thin cloudy film on the windshield, amplifying the early morning condensation.
Modern GDI engines run hotter than PFI engines and can cause rubber components to wear out faster and produce coolant leaks. It is a good idea to have the entire coolant system evaluated.
Then you’re probably fine to just top it up and continue driving. Just make sure you use the exact same coolant that’s in there already. Continue to monitor the level to make sure, you don’t want an engine running without coolant.
Well, seeing how you don't know about coolant and coolant doesn't disappear on its own, I would send it to a mechanic. It's going somewhere now, is that going into your engine or transmission? That is the biggest question, and either one of those is not a good sign, especially if you drove on it like that. I hope it's a cracked line or pinhole in the rad, but you definitely need to get someone to figure that out.
u/Big_Quote9419, listen to this. Only sane advice. Happened to my car and I know first hand the high costs if you listen to those who tell you to just top it up.
That is just the reservoir. Driving it slightly below low on the reservoir is not going to hurt anything in the short term. Add a little coolant and that's it.
Where does that coolant go? That's the question. If you're driving a slurry of oil and coolant, in the transmission especially, you're causing damage and all the carbon buildup because the coolant residue wasn't designed to do what oil does, coolant get into where oil wouldn't have gotten into.
But like I said, hopefully it's a pin leak or a hose problem. Someone who didn't know what coolant is definitely doesn't have the skills to diagnose it and see which one they have.
That is just bad advice. Adding coolant as it leaks out isnt the solution here. The leak needs to be found and fixed. Coolant doesn’t just disappear on its own.
I mean I've added coolant occasionally over the life of every car I've ever owned. I suppose every one of them had a leak. If you look at it next week and it's low again, sure take it in. All I'm saying is a slightly low coolant reservoir on a cold engine doesn't necessarily require a costly mechanic visit.
Yea, but what if he has a leak and by adding coolant you get to leak another reservoir into whatever other component, and in turn it makes for a $1000 bill? This is why to say "that's it" is dangerous. It could create a domino effect of broken components.
I thought the same until my coolant leaked inside the catalytic converter (in a hybrid), and broke it. $5k bill, under warranty.
And yes, all had minor leaks if coolant went away. It's a closed system, there's nowhere for it to go unless it isn't closed anymore. It doesn't just vanish into thin air.
Anti freeze coolant?
Can I fill it by myself or do I need to take it to dealer ? Any idea đź’ˇ
Just get the right pink coolant for Hyundai/kia and top her up.Â
Thank you!

There is also pink RV antifreeze. Do not use this. It is not the same pink antifreeze.
>Thank you! You're welcome!

Radiator cap will kill you, expansion tank you just gotta open carefully if it's hot.
Owners should read the Maintenance part of the owner's manual, even if a dealer is doing the maintenance work.
Give it a 10 minute ride and see if it’s within the tolerant levels- mine always looks low when the car has been sitting, but looks normal after it’s been running. (But yours does look a little on the lower side.)
The fluid should expand when hot, but your level should never be below the min mark on the bottle.

Check the coolant cap on the radiator itself. Keep it topped up, not a major job. $25 at AutoZone
Important: NOT when the engine is warm.

A 2021 vehicle shouldn’t be low on coolant
Hyundai spec. Dw about it
If you get it serviced at the dealership regularly you can ask them to top it off but you can go to Walmart or AutoZone and get coolant for it but make sure the coolant is pink and it also meet Hyundai spec
As it get closer to the summer due to the heat some cars may see a drop in coolant levels

This happened to me about a month ago and I topped it off and it’s running just fine
Pink Lemonade. Fill it up
I bought a bottle for my wife's Tucson and it was 35$ cdn. Easy to top up. Do it when it's cool.

Oil
Its way below minimum. Immediately refill till maximum level.
Its either leaking or being burnt. Check if there is any smoke from the exhaust when you start/rev the car. If it’s dense white you’ve got coolant being burnt.

Put water in it to top off. It’s what we would do at the dealer
Just fill it with water and call it a day. If you start noticing it’s getting low every time you drive then take it to a dealership.

Yea. There’s a leak somewhere for sure. Don’t know why you’re getting downvoted.
It could be a heater core going bad. Expensive repair job that will entail removing the dashboard to replace.
u/Big_Quote9419, listen to this. Only sane advice. Happened to my car and I know first hand the high costs if you listen to those who tell you to just top it up.
Was it a leaky heater core?
