Coolant/antifreeze dilemma
« June 04, 2020, 11:13:53 »
Hi everyone. Is there anybody that can help me with which type of coolant I should use ? My i30 is 1.6 petrol 2013 and I am in the UK. My car has the Original Factory fill coolant still in it, (very low miles 18,000) which is Green (not neon green). Like many people have posted all it says in the handbook is to use ethylene glycol, but ethylene glycol can be IAT, OAT, or HOAT and I know that some of these really shouldn't be mixed. I called Hyundai but they couldn't even tell me me what the anti corrosion base is from the factory fill, and that they do not even sell Hyundai branded coolant. They suggested that I call a dealer which opened another can of worms. I was told to do the initial change at 60000 miles or 6 years then 60000 miles there after I was told to change it every 4 years by another dealer, yet another dealer said every two years and that my antifreeze should be blue not green. And these dealers are meant to be trained ??? They all then offer me a universal antifreeze which is blue at £9.00 per litre made by Quest  consumables, the same as kia would offer. All it says on their spec is" includes corrosion inhibitors."  So I phoned Quest and they knew nothing about this antifreeze except that I should change it every 2 years, yet they supply Hyundai and Kia throughout the UK.  I would like to think that Hyundai have looked at this antifreeze and that it will mix. HYUNDAI, IT SHOULDN'T BE THIS DIFFICULT TO REPLACE ANTIFREEZE  !!! But considering all the different views I've had from different dealers, my questions are

Does anybody know what the anti corrosion inhibitor is from the factory fill, and will the blue antifreeze mix with it as I'm pretty certain that not all the old antifreeze will come out?

I read somewhere while searching that Asian cars like phosphate based anti-corrosion

I've seen ravenol  HJC fl22 coolant which is without phosphate,  nitrates,  amines, and silicate.  This meets Hyundai long life coolant spec 07100-00200, 07100-00400, 00232-19010 but has no phosphate .

Any other suggestions, thanks guys.  Sooo confused

Ha ha !! I'm replying to my own post as I cant see how to edit.  Just to confuse me even more the ravenol site in the UK says there is no phosphate, amines nitrates or silicate,  but the German site says no amines silicate or nitrates only. :crazy1:

My 1.6 2 door (euro build) came pre-filled with 10 year (yellow) coolant.

I was informed By Hyundai any of the modern coolants can be used as long as they’re not mixed with another coolant, the change interval would be dependent on the coolant used which should have the year specified on the bottle

Hi, thanks for replying.  Do you think that Hyundai meant that modern coolants are ok as long as any previous coolant is completely flushed.  I was hoping not to spend a long time draining, refilling  letting the engine cool down, draining refilling etc.. but I also wouldn't want any mush forming if some old coolant remained in the system.  I wonder why Hyundai have used yellow in OZ but green in the UK and I think green also in the states. Is your yellow coolant ethylene glycol?  Thanks again

Hyundai use other colours here too, Red or Green are probably the most common.

Yes you must completely flush, even if using the same coolant as you don’t need the old contaminating the new, distilled water is pretty cheap :)

You mentioned in the first post that the colour is green, not neon green. When the (neon) green antifreeze gets old, it will start looking "just" green. And if you don't change it soon enough it will become more darker. Eventually the neon green will become brown, if not changed.

I did some research about the antifreeze when first time changed mine. I had green one. Someone said that green is not good for aluminium. But when I looked more about the green ones, many of them had additives that made them usable with aluminium cylinder head. I've been using green (which can be used with aluminium) since. I thought about flushing the system and going to red one. Here the recommended change interval for green is 2-3 years. For red it is 5-7 years. I change my green every 2 years (50tkm). And I mix it up with distilled water.

 :crazy2: so many types, so many colours.  :wacko:. Hi Sundiz, thanks for replying. I mentioned  neon green, as here in the uk that colour has been around for years, and the green coolant in my car is definitely not that colour. Where your profile says VIP, that's like the colour that I dont have, the green that says your name is more like the green that I do have. My wife's kia venga has the exact same green coolant that I have in my i30.  The Kia handbook  says first change at 120 months or 100,000 miles, her car is 9 years old so I checked the coolant. Ph which was 7 and freeze protection down to -35c the voltage to check  for electrolysis was .149v (saw a brand new Kia on you Tube tested at .165v as long as voltage is below .3v apparently  it's ok. The ph is now neutral at 7, and will soon probably start going acidic , but it has done well for 9 years.
My i30 ph was a about 9.5 so not too bad, voltage .129.  So again not too bad. I am ordering  a coolant refractometer to check water to coolant ratio. A bit confused why kia is 100,000 miles for first change, but Hyundai is 60,000miles for what looks like the exact same coolant. I'm still undecided about what to do. I wont be going to a dealer as I prefer to do it myself,  and I dont think any dealer here would flush my coolant several times with de-ionised water to get it clear before refilling. I think they would drain out what they could , then put in the blue coolant. Some coolants that say "meets Hyundai long life coolant "  dont contain phosphate,silicate, nitrates or borate. So I have no idea what could even be in them.

Doubt you will be able to buy it here,  but the safty sheet and the website ink might give some clues about what it is made up of.

Hi Lorian, thanks so much for the info and link, its brilliant info, more help than calling hyundai customer service.  :goodjob:  I'm no chemist but it does confirm that it contains phosphate, and that it is green. just wish that we could get that here in the uk. Just out of curiosity have you had to change your coolant yet,  if so what did you use? And thanks again.

I believe phosphate based coolants arent so generally available in the EU as we have more areas with hard water than Asia/US and it stops people mixing them with their tap water and causing scaling issues. You can find them but more diffcult to get and $$$

Personally I'd buy a good quality pre-mixed LL antifreeze (you would need two 5l containers I think) - and do a full fluid change. No need to worry about what water to use or what was in there before.

Maybe a bit late, but I was confused by all the colours etc for antifreeze whenen I came to do my i30 CW 2010 model in 2016 at about 75000 miles.  Couldn't get any sense from local dealer (except buy it from us & let us do the change, just in case you get any air locks, etc, etc).  Couldn't be any more difficult that the peugeot 306 I used to own.  I did write to Comma Oil technical Dept and got the following very prompt & helpful reply:  "According to information sourced from the manufacturer, Hyundai recommend using coolants based on ethylene glycol with OAT style corrosion inhibitors. Our corresponding technology is Xstream G30. In respect to colour, please note the colour is only due to a dye and should not be used as an indicator of performance. That being said, the industry typically dyes OAT style coolant red/pink but be aware this is not a requirement."  So that's what I used Xsream G30, which is ared colour.  And no problem with air locks & the like & draining the system is easy-peasy.  One word of warning, though, if you're going to use deionised water to dilute the antifreeze (and most say that is much much better than using tap water), buy it as deionised water for filling steam irons from your local supermarket in 1 litre bottles rather than from your local motor factor.  It works out at about a quarter of the price that way and, despite what I was told by my Hyundai dealer, there is NO difference chemically between deionised water that you buy from Hyindai parts counters and that which you get from Tesco or Asda.

Hi, thanks for  chipping in. I got so many different answers from main dealers when I asked how often the coolant should be changed after the initial first change, I really ended up with very little faith in any of them. I have since found a company in the uk that supply low phosphate coolant for japanese and korean vehicles. I need to call them to clarify which one they reccomend,  as they also have a silicate free coolant as well. Off the top of my head they are called mpm oils. Also not from mpm though is ravenol fl22, please note that I'm not recommending these coolants, I'm still  checking them out. I'll also check out  xstream 30.  Also agree  that deionized water is essential.
