3.3TT What coolant?

[StingStingStingSting]

Kind of embarrassing question, but I just bought a used Stinger a couple weeks ago. Noticed my coolant overflow was basically empty, went to Canadian Tire and bought OEM brand Yellow coolant for Kias. Go to fill and realize the coolant in my Sting sting is green. Was talking to the dealer, they just told me to fill it up with green coolant and couldn't tell me anything else.

Manual says: The engine in your vehicle has aluminum engine parts and must be protected by an ethylene-glycol with phosphate based coolant to prevent corrosion and freezing.

Under fluid specifications it says:
Mixture of antifreeze and distilled water (Ethylene glycol base coolant for aluminum radiator)

Coolant I bought:, OEM brand Hyundai Kia Yellow

I'm assuming I need this instead, Prestone Asian Green

The yellow coolant is ethylene glycol based and meets ASTM D3306 and JISK2234 but doesn't mention phosphates. The Prestone Asian Green meets ASTM D3306 and D4985 but doesn't mention JISK2234 or phosphates, and it lists compatibility as POAT, but doesn't mention ethylene glycol. Yellow doesn't list a compatibility.

Should I go pick up the Asian green? Or will the yellow be ok? Or something else entirely? Just topping up. I read mixing the new OAT HOAT and PHOAT coolants with the IAT coolants will make gel. No way the Kia dealer put IAT in a Stinger right? I have an appointment to get my diff fluids and transfer case fluid changed 9 days from now, maybe I should wait and just let them top it up? Overflow is empty when cold. They flushed it around 30,000 km ago. Tried to post links but since I'm new I'm blocked so I attached pics of the coolants. I'm probably overthinking this but don't wanna chance it. Sorry for the long ass post but this coolant stuff is driving me nuts. Thanks

You need to match the coolant colour or risk the coolant turning to jelly. Go green for sure.

Yeah for sure. I'll top up with Asian Green and keep an eye on it. Thanks bro. Just hella paranoid it's got the old school IAT stuff in it. I asked what brand they just said green. I had major issues with the last dealership I dealt with, not Kia, but I've heard Kia dealerships don't have great service departments. Also, I'm in NS in the valley! Haven't seen any Stingers around NS except one and I figured its the one I ended up buying a couple weeks ago lmao, maybe it was you I seen that day haha

Welcome! I bought mine new in 2018 so totally possible it was me. I see quite a few around HRM these days, not like back in 2018 when I first got mine and I felt like it was one of the only ones in the city. I fully service mine and never go to the dealer anymore.

I got paranoid too. When I saw KIA on the bottle I figured that was the one. Ima pretty sure it's green.

Color isn't tied to type of coolant any more. The Stinger has come with several different colors, including green (*not* the same as traditional glycol green), pink (2020+?), and possibly orange (*not* the same as traditional GM DexCool), and there are identical "Asian" P/HOAT formulations in those colors plus blue.

So sticking with the same color makes sense, but if you can't, you'd be better off mixing colors within the same formulation, vs. mixing formulations while trying to match color. Post below has AutoZone links to the same PEAK coolant in 3 colors.

I don't think the color is definitive the way it used to be, and remember seeing the same formulation (POAT/"Asian vehicle") in several colors -- check out the labels for Peak/Asian pink, blue, and green below. Green says Kias 1990 and up, but ingredients match.

I've also read that Hyundai/Kia switched over from green to pink OEM either for slightly longer life or arbitrarily based on production line, and that they're otherwise compatible, and the Autozone/Oreillys lookups showed green for my Stinger even though mine is bright pink. Since they looked identical I went with pink mostly...

P-HOAT (Phosphated Hybrid Organic Acid Technology) That is what I have. It is pink but I don't think the color matters just as long it

formulated for aluminum engines I suppose.
