Hi all,
Going to check with the dealer after the bank holiday but want to check what actual owners/future owners think first.

I was having a look around under the bonnet and noticed that the dealer has put a good bit less than the ‘minimum’ coolant in the vehicle when they handed it over (yes I should have checked this before I took ownership).
I’d say it’s sitting a good inch under the minimum level marker.

is this a big deal of EV as it is for ICE vehicles?
It’s not showing as an error on dash so just happened upon it.

And if I’m to top it up myself (which I imagine my dealer will suggest) does it take any basic coolant?

This may help, does not say what coolant to use.


This may explain what it does,

Great thanks for the help. Will contact my dealer about it. Just seems strange they put some in but not the required amount.
was wondering if this is an ev specific thing that was done on purpose.

It's almost certainly special non conductive coolant, and you MUST use the same type to top up, and most definitely DON'T ADD WATER!

If the filler cap has a hand with a stop sign and a picture of a mechanic with a spanner, you need to get your dealer to attend to it. The fluid level is more likely to drop if you ordered a car with heat pump and they didn't fully run the special bleed process when they built the car.

Awesome thanks very much. I don’t have a heat pump and the coolant is pink.
But as car is only a month old I think I’ll take to the dealer anyway.
I should be due an upgrade soon anyway to fix preheat if they ever acknowledge it’s a problem.

found the same issue on my EV6 in Ireland. In with dealer now to get it topped up and yes it is special non conductive coolant that is required
Ah ok good to know. When I left mine in they said there is an issue with pipes and they can hear liquid sloshing about where they shouldn’t!!
All from needing a bit of coolant topped up!
I’ve to wait until 19th for replacement part apparently.
Will be worth if I can get the car back in decent shape with heating working etc.

here’s hoping you don’t have the same issue.

just also can I check, was your coolant pink?
I know you mentioned non conductive coolant and I’m wondering how to know what coolant was put in there in the first place. It looked like regular stuff but I can’t tell the difference!

No idea to how to tell the difference :) Service guy just mentioned that I did the right thing bringing it back to them as if I had filled up myself with the incorrect coolant it could have caused a lot of issues.

Taste it. They will taste different.

True story. Oxidation and corrosion if it's not the right stuff.

The coolant my dealer has been giving me is blue. The original was pink. I seem to have a pretty brisk leak. View attachment 6295
I would 100% be bringing this back to the dealer asap. My dealer didn’t know there was a special coolant needed for the car until the spoke with head office.
Once they did they replaced with the proper coolant and even provided me with an extra bottle should I need it (see picture). So you can hopefully show this to your dealer and insist this is the coolant used for your vehicle.
Hope this helps.

You should insist they use the right coolant. As Mulinator stated the wrong coolant will generate corrosion and other issues. I would go to another dealership if they won't budge.

No. It's certainly important, and the vehicle will behave very poorly if there's no coolant, but ultimately stuff just stops working: motor power will be limited, maximum charging power will be (severely) limited, etc. You should still be able to limp around, and if things go as designed, nothing will destroy itself. It's bad, but not as bad as an ICE engine where running without coolant, the engine will destroy itself in minutes.

Not in the EV6. In the I5 it is, but Kia took a different approach. That said, I'd still use the same type for corrosion reasons. I'm sure there are some special properties/additives in the proper pink coolant, but low-conductivity isn't among them (and thank god, because it's like $1000 a fill for the Ioniq 5).
