Low Conductivity Coolant Change Procedure

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.

 

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

 

That or just use deionized water and don't worry about the freezing and corrosion stuff

 

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.

 

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.
