Following up on my earlier post, I completed the "inverter coolant" replacement as it's described on the invoice. $248 from Roseville Hyundai, and they gave me a 10% discount because their bleeding machine had a problem so it wasn't done after 3 hours. And apparently my 12V battery died during the process, so they replaced it at no cost. Hopefully I'm good for another 3+ years.

 

I just got home from Jim Pattison Hyundai in Surrey BC Canada after getting my 2024 IO5 charging port door replaced under warranty. While there, I inquired about the LC coolant change due on my car in a couple of years. I was shocked when they said it didn't need to be changed until 60 Mo. or 60K NOT the 36 Mo. originally listed and ....... the price listed was $387 Cdn ($276 US) plus tax. WHAT A RELIEF! I talked with one of the service guys and he said they were familiar with the procedure as they had done it a fair number of times mostly due to cars needing the ICCU replaced (which also required the LC coolant change). I suspect the interval change is likely due to them not knowing exactly how quickly the new coolant would deteriorate. This is Gen. 2 as the first LC coolant broke down quite quickly due to crystallization formation or something like that. Any way......What a relief. My AWD IO5 has been such an enjoyable car to own and drive. My previous car was a little Accent HB so, a HUGE change in size, noise, power, and comfort.

I go to this dealer, note some of the service advisor have no clue regarding I5.
The ICCU has nothing to do with the blue LCC coolant used to cool the HV battery. The pink coolant is the one that goes through the ICCU.

 

If somebody replaced LC coolant in South Florida, could you please recommend a dealer that knows how to do it. How much did it cost?
I tried to schedule several appointments with Lehman Hyundai. Nobody knew what I was asking about, promised to call back and certainly never did.
Thank you.

 

Not quite South Florida, but Hyundai of New Port Richey (just north of St. Pete) seems extremely competent. They have three EV techs last time I asked and have always gotten me in and out promptly. I haven't yet needed the LC coolant replaced, but that's where I'll go.

 

2025 AWD SEL has coolant replacement (no modifier) at 120,000 miles and again at 144,000 miles, after which apparently no maintenance of anything is required. Of course, I told them I drive 6,000 miles a year, so they don't think in 2042 I am going to give a .

 

2025 models doesn't have the LC coolant. I am assuming you are referring the regular pink coolant.

 

Yes, they don't reference what type or color of coolant they are referring to, so they must mean the "regular pink" coolant. We 2025 noobs don't know nothin' yet ...

 

Yes, they don't reference what type or color of coolant they are referring to, so they must mean the "regular pink" coolant.

Actually, they must mean the pink coolant since it's the only kind the 2025 model has.

But waiting till 2044 to replace the pink wouldn't be good either. The pink coolant gets replaced every 120,000 miles OR every 10 years, whichever comes first.

 

Since I was at the dealership anyway for the dreaded ICCU issue, I asked them about this service. $589 was the quote, and they said it didn't need to be done until the car hits 30k, which is wrong on 2 counts. Per the manual, it's 35000 miles or 36 months. Based on time, the car is already there.

 

I wish, at this point, just put out a TSB saying regular coolant is OK or still compliant. I mean, 2025 i5 doesn't even have the second loop, EV6 doesn't have second loop so why is LC coolant even needed for at this point? (Also, really needed to be changed every 40k miles?)

 

Two months ago I called our dealer and was quoted $350 for the low conductivity coolant fluid change/flush. A month later when I called to make an appointment to do the change I was told the cost would actually be $750. I cancelled the appointment and called the next nearest dealership that is a 500 mile round trip drive. They quoted a cost of $980. So last week I went back to our "local" dealer to have the LCC done and it ended up costing only $525. Not great but it could have been worse.

 

For those in SoCal, I just had this done at Tustin Hyundai. They charged $230 total (62 for parts and 168 for labor).

 

FWIW Ron Tonkin in Portland, Or quoted $289...They have been consistent in what service has told me in the past.....2024 is not there yet...

 

Check this out.


I was quoted $1200 for a low conductivity coolant swap from my local Hyundai dealership. The KIA dealership down the road quoted me $295 using the SAME coolant part number. (Canada)
um022ch270

You will see part number 00232-19113 listed all over the place for low conductivity coolant for the Ioniq 5.

I have now spoken to two separate parts departments at Hyundai dealerships that confirm UM022-CH270 is the NEW part number for this coolant.

Many people will tell you that Kia dealerships cannot do this service because their cars do not use low conductivity coolant.

However, if you google the above part number, or something like "BSC-2 TSB", you will come across multiple NHTSA TSBs . Some for Hyundai and some for Kias


You will even see in the TSB, that the procedure requires a coolant flushing set. with a part number of KQ253-CV158-QQH


From my perspective, there is nothing proprietary about their coolant or their procedure. In my opinion they're simply attempting to make ridiculous markup to cover the loss of service revenue from EV's.

I have contacted Hyundai corporate and CBC marketplace. We will see where this goes.

 

Got my second quote today for this work here in Honolulu, where there are really only two Hyundai dealers.

Some time ago dealer #1 quoted me $680 for the job -- they had just received the vacuum pump widget from Hyundai and were only beginning to play around with it.

Today dealer #2 (talkin' bout you, Tony Hyundai of Waipio) quoted me $870 for a "manual" replacement. They do not have the vacuum pump and do not plan to get one, and instead somehow do three drain/refill cycles manually, WhateverTF that means. I sure hope for the sake of their EV techs sucking on the hose that the blue koolaid tastes better than it looks.

Is this "manual" replacement really a thing, has anyone else ever heard of a reputable service department doing this? And where would you take your own I5, to the cheaper dealer #1 using the vacuum pump or the more expensive dealer #2 with the shall we say more artisanal approach? 😉

 

I read on the procedure to flush coolant manually requires removing entire front bumper cover along with the front ventilation flaps to access the drain outlet for the blue coolant and that would result several billable hours to do so.
Having the special hyundai pump equipment requires no bumper removal thus less billable hours.

I would go with dealer with the special pump.

 

Daedalus please post your experience R&R! I'm sure there's lots of interest.

 

Got an email this morning. Unfortunately the blue coolant is apparently on nationwide backorder, and my order was cancelled. Hyundai can't seem to manage inventory very well. The ICCU was bad enough, but it should be pretty darn easy to estimate how much maintenance items will be needed. It's not like there's an aftermarket alternative.

 

Today - Blue coolant flush and change $280.

 

For an Ioniq 5? Do you have a breakout of parts and labor from the invoice?

 

Ioniq 5, Parts $119.85, Labor $159.99, Hyundai dealer.

Since I thought the price was reasonable I had them do the pink coolant also. Parts $98.83, Labor $159.99. This was completely optional as it's not required yet according to the owners manual. But I have seen the results of leaving coolant too long in ICE cars and the resulting corrosion is not nice.
I could not see our car thru the small window in the seating area where you can view the workshop. But I did see them service a Kia ICE car using a nifty air operated device that did a flush and exchange of coolant quickly.

The main reason for doing this is to make sure that the warranty for the battery and drive train is good thru the 100k miles. After that I'll do all the maintenance. The car is at 64k miles now. If we keep driving this car like we have been, we'll be at 100k in 2 more years.

This car has been cheap to maintain. So far 1 set of tires, 1 set of wiper blades, and this coolant service are all we've paid for out of pocket. Way cheaper than any ICE car I've owned. Took a look at an Ioniq 9 while waiting. My thoughts on this was that I'll wait and buy a used one after the 100k mile warranty is over and it will be dirt cheap.

 

$120 means they most likely billed 2 gallons of the coolant, which makes you wonder how much they actually removed. A standard range I5 contains 2.32 gallons of blue coolant nominally (no heat pump) and all models with the larger battery have at least 2.96 gallons, nominally. The labor looks to be 1 hour perhaps, which seems cheap, considering the job should take 2-3 hours per the video the ioniqguy posted.

Going off on a tangent here, I can't possibly fathom why the pink coolant needs to be changed the 1st time at 120k miles or 10 years, and then every 25k miles or 2 years after that. Makes no sense whatsoever!

 

It does seem odd. Perhaps there's some significant difference between the way the original coolant is installed and the way the replacement is installed.

For example - if temperature or oxygen exposure was a factor in degrading coolant lifespan, one might imagine the factory using refrigeration or an all-nitrogen atmosphere to address that risk when installing the coolant in a way that our local dealers could not.

But this is wild speculation on my part, based on no facts whatsoever (obviously!).

Certainly has nothing to do with exposure to air. You can take off the reservoir caps whenever you want (unless hot!), and the systems are designed to cyclically vent pressurized air when hot and suck air back in when they cool, no different than many ICE cars.

This is concerning. I just went to Hyundai of Ft. Myers to get my LCC changed and they only charged me $180. They used a "coolant kit" (06-000035) for $48.91 and one unit of 00232-19091 for $85.32 (the rest was labor). At checkout they said they should have charged me $260 but they'd "honor" the original quote. Besides not being nearly enough fluid for a full exchange, now I'm worried about what they may have used.

I wasn't going to raise a stink over it before I saw your post. I've only got 15K miles but I'm at 3.5 years so I figured I better do it to satisfy the warranty. I didn't really think I needed it. Now I'm not so sure. It'll be a while until I hit the "mileage" requirement. Anyone got any input?

If the receipt and service records say you had the proper service done, then as far as the warranty is concerned, you're OK. In another 3 years, replace it again.

 

Certainly has nothing to do with exposure to air.

In my defense, that was an attempt by me to offer a hypothetical example.

I should probably have said "if Feng Shui, Ley Lines or The Curse of Cthulhu was a factor...". But then I would have had to invent remedial actions the factory could take that were not available to dealers.

 

$310 plus tax at Fred Beans in Flemington, NJ. Also was advised to change the reduction gear oil in each motor, and I'll be DIYing that one. See Motor Gear Reduction Oil Notes

Invoice didn't offer breakdown of parts vs. labor because it was combined with a reduction gear oil change in one motor they mistakenly did for cheap after I called them out.

 

$286 plus tax at Walser Hyundai in Brooklyn Park, MN. I called every dealer in the Minneapolis St Paul region and they were the lowest.
