Your picture does not indicate any blueish tinge in the reservoir, so I doubt it being a "hybrid" cooling system (some mid function of a no conductance insulator to superconductor, ie: semi-conductor) but I would check anyway with the service dept, hopefully it is just a paperwork error...seeing as the 2 types should not be mixed BTW good observation on the part# indicated on the invoice
@Ginginova , Thank you for the I5 image. I stand corrected, and should have researched my statement further It seems weird to me that Hyundai would split its cooling system on the I5 in this way since it implies that there must be some kind of heat exchanger between the two circuits. The video answers some of these questions, though. I must try and get a proper look at the I5 HVAC system! John
Ok picked up the coolant today, the jugs are now brown coloured. Parts guy definitely confirmed its the coolant for my car. It does indeed say on the label that it is blue coolant with correct change interval. Of interesting note its got similar warnings as brake fluid to avoid opening seal prior to use. It has a shelf expiry date of 2 years past manufacture date. I have to wonder if its hydrophilic.
Some more clues, I verified with my TDS meter today this blue coolant does indeed have very low electrical conductivity. This from labels list basic ingredients its got ethylene glycol and unidentified corrosion inhibitors in it, looks like the fluid is made for Hyundai in Korea by a 2nd tier Korean petro-chem corporation called Kukdong Jeyen.
Thanks for the photos (both posts). A lot more information than previous (new part#). Definitely looks like the right stuff. Maybe when supply constraints have achieved a normal run of the mill operation, the price will follow. Just curious, with the TDS meter...does it measure conductive dissolved solids?- is that how it works? What was the reading (make of meter would also be nice), also curious a reading of the green stuff (new and used) if anyone out there has one. In the meantime, having that initial measurement on hand when new, would be a good benchmark down the road (@ 120K kms)
The TDS meter simply measures the electrical conductivity of the solution and estimates the TDS(total dissolved solutes such as salts and minerals) as a parts per million unit of measurement. Today I measured a sample of conventional new yellow(universal) coolant measured at 580 ppm, a few weeks ago I think I measured some generic green coolant above 600, my well water today was 450 ppm, the same water run through a reverse osmosis filter 28 ppm and the the blue coolant today was the same around 26 ppm. I have something similar to this generic unit found on amazon for around $20, just I paid fair amount more for it a few years back
Thanks for that. Maybe all we have to do is purchase the cheap stuff and run it through an osmosis filter
The EV6 has only one coolant reservoir unlike the ioniq 5's 2nd one for the low conductivity coolant. KIA EV6 Online Manual in Eng Scheduled maintenance for coolant change is 10 years or 210k kms the every 30k / 2 yrs KIA EV6 Online Manual in Eng Coolant spec is standard anti-freeze KIA EV6 Online Manual in Eng
It's strange no reviewer has ever mentioned this significant maintenance cost. I suppose the warranty will be void if one does not change the coolant on time, even though it's more of a safety precaution
When my brother eventually goes for a test drive (in any Hyundai EV product), he will specifically point out (if applicable) any coolant reservoir filled with “blue” coolant and ask to see the maintenance requirements for it and get a quote on the cost for that maintenance event.
When I picked up my 21 MY, the techs worked out the price and schedule for all maintenance, only exception was the cost of the Blue coolant which was "ballparked" ~ the same cost as @apu post. Only addition to the schedule was the gear oil change
I also find it strange that when you point out this potential maintenance pitfall to a buyer of a new Hyundai EV they treat it as inconsequential esoteric information and they would rather focus on some relatively irrelevant detail like the colour of the infotainment bezel being ojectionable. I think until potential buyers wake up and make Hyundai uncomfortable with the answers to these questions not much will change. Personally unless the coolant becomes significantly cheaper in the future, once my battery warranty expires I will switch the coolant over to conventional fluid.
Wow that is nearly 20 liters of coolant capacity for AWD large battery , even the "cheap stuff " from Canadian tire will set you back over $100 plus a couple of hours of shop labour, so $400 instead of $ 800-1000 for the Kona, much better lol. At least the change intervals are better.
"Worked out?" What's to be worked out? It's printed in the owner's manual and online. My garage tried to "work out" their own schedule too and I just keep waving the printed schedule in their face. Forgive me if I've misinterpreted your meaning.
I called 3 dealers here for an ioniq5: Richmond Hyundai quoted me $270 for the blue LC coolant change (He insisted it was the LC coolant) Surrey " was $720 Lougheed " $600 Tech was quite helpful and researched the issue. Told me they test it (because of the expense) but have never had to change it
Should have stated "worked out the cost according to the maintenance schedule" Sorry for the misunderstanding
When visiting for my first service (and being greeted by blank looks) my service manager literally said to me, " Ya, we haven't had much experience with EVs but we were thinking of coming up with a service package. What do you think?" I thought it was a bad joke is what I thought.
So the Ioniq 5 uses 2 coolant loops. A electric device and motor loop that uses conventional coolant, 6.4 liters for 2WD and 6.8 liters for 4WD The battery coolant loop uses 11.6 or 11.9 liters of the low conductive coolant respectively. If Richmond are actually selling the LC coolant at $45 per 2 liter jug installed that would be quite fantastic, alas I have my doubts. I suspect your service writer may have confused the 2 loop capacities and might be quoting you for 6 liters of LC instead of 12 liters.
