Thank you for the very good explanation. I've always been told to never mix colors, but seems like color is irrelevant. Just don't mix the technologies.
Very good and informative. Also make sure that the dealer and shop use the correct coolant when they top-off your coolant and don't mix incorrect antifreeze in your radiator.
Very useful - thanks. Some people said you can't mix colours but that seems only true where specific antifreeze technology is different. Glad you have explained this properly now.
Excellent information and to the point...just print bolder and clearer so I can read spelling to make notes for my own use. But......You helped make me make the correct choice with my 2020 Hyundai Santa Fe with pink cooliant in it now ! Great job ! Thank you my Notes ate now in a book forever !
I think the “main” in all of the automotive glycols is ethylene glycol. It’s the additives that are different. Prestone all makes all models says it can be mixed with any other coolant. I have a sneaking suspicion the main problem all along causing most of these horror stories is just dex-cool, people mixing stuff with it and it gelling, but the truth is even people getting a leak and it gets low and it gels up, without mixing it with anything. Just the thoughts going through my brain as I watch the vid.
Likewise brother thanks for the very informative help I'm actually in the position right now stuck between a rock and a hard place somewhere is there any way you could help me right now as of 212 p.m. Thursday afternoon? I'd appreciate a big time couple questions
In my semi I definitely know there is a difference some end up breaking down quicker than others that's for sure I've done so much testing I have 2 trucks 1 has had the same coolant almost 15 years yes I've had to add some here and there and yes I add the minerals that it's lacking after I have it tested now my other truck man oh man I've thrown just about every kind of coolant in there that I can think of I had it so messed up and acidy a bunch of times that now no matter what I put in there it turns rust / mud red Coolant and oil is sent out to get tested EVERY service I do
The main issue is the corrosion inhibitors from different types react and neutralize each other so you start getting a lot of corrosion. Another problem that arises is that if you switch from one type of anti-freeze to another (complete drain and refill) is that all engines have some corrosion and dirt in them that's adhered strongly to the interior surfaces , when you change the type of corrosion inhibitors you are using ,all of the dirt can suddenly come free at once and clog up your radiator and heating core. I run into this issue quite a bit with forklifts , the owner buys a used forklift and switchsd it over to green glycol so all of his forklifts use the same antifreeze , and a week later the radiator is clogged up with rust and sludge.
Newer Asian cars require silicate free HOAT. Go for prestone or zerex asian car formulas if you have a Japanese or Korean brand. In contrast European cars need silicated HOAT.
@@GoofysBandit In Europe, problems with hard water minerals forced coolant technologies to be phosphate-free. Calcium and magnesium, minerals found in hard water, react with phosphate inhibitors to form calcium or magnesium phosphate, which typically leads to scale formation on hot engine surfaces. This could lead to loss of heat transfer or corrosion under the scale. To replace phosphates, conventional European coolants contain a mix of inorganic oxides like silicates and inhibitors called carboxylates. Carboxylates provide corrosion protection by chemically interacting at the metallic corrosion sites, rather than by forming a layer of inhibitors that cover the total surface. The mix of carboxylates and silicates is also called a hybrid technology because it is a mix of conventional inorganic technology and fully carboxylate or organic technology In Asia, problems with water pump seals and poor heat transfer have led to the ban of coolants containing silicate. To provide protection, most coolants contain a mix of carboxylates and inorganic inhibitors like phosphates. These coolants are hybrids. They are distinct from the European hybrids due to the lack of silicates
@@coltonzelkin2694 That's ignorant, how can you say I'm wrong about what I didn't see. It says use on any engine, so what did Honda change in the metal too in the early 2000's to need a different antifreeze. They're just selling dye for twice the price.
Thank you so much! This was very informative. Just to make sure, I have a 2020 Kia Rio. The OEM coolant that came in it has the color green. It is P-HOAT ethylene-glycol based coolant. I need to top off my reservoir, and the closest thing I found was Zerex long life for Asian Vehicles. It is also P-HOAT ethylene-glycol based, but the color is red. The video says that color is just a dye, but just wanted to confirm that this will cause no damage mixing the green stuff with the red?
Is there any test which can tell me which technology is in my car? It would have been Dexcool when the car was new but I bought it used and I don't know if the current orange coolant is Dex or the new stuff which is also orange.
My coolant colour is PINK. Ethylene glycol is written on the coolant container. But, in your table, Pink color falls under HOAT. Now, i am confused whether my coolant is IAT or HOAT? Does HOAT contain ethylene glycol? Obviously OAT is propylene glycol. Then what is HOAT?
You didnt explain anything about for example PRESTONE All CARS coolant, is it really mixable with ALL, I have Alfa Stelvio 2019, can I add Prestone All to my Mopar coolant?
I have Hyndai Santa Fe 2009. Green coolant. I have not changed it for 10 years. The fluid looked always bright green and no speck of inpurity. But too old to stay in the system. I went to Hyndai dealership and picked up Hyndai original brand coolant that is for my car. Also green in color. I backed up car on 1 foot high ramp to lower the front. I drained old staff. Took a sample bottle. It appeared somewhat transparent bright green and no particles. I flushed the car with tap hot water. Drained it 2 times. Let the car run 15 minutes with heater at max speed and heat. Drained it again. The water was clear but maybe slight hue of green. I used an air pressure to empty overflow tank into the top of radiator. I rinsed again with bottled distilled water through the overflow tank. Let it run a bit and drained it. Then I added 1L concentraded coolant into the radiator. I added 0.8L of deionized water. It was full. I let the car work 20min with heater and AC on. No top up needed. I took for a slow ride around the block. Looked at fluid and it had a hint of foam (2-3 creamy bubbles). I took for 20min drive to work. The radiator cap appeared to have plenty of yellow (curry) light foam. I wiped it off. The fluid itself looks green but not as transparent. It has tiny white specks as deep as I can see. Not on surface. I looked inside the overflow tank and it looks very clean bright green with no issues but a hint of rainbowy oily surface. Perhaps from the coolant itself. 1) Did I not suppose to pour concetrate into radiator but do it mixing in the overflow tank? Hence concentrate got foamy as it was blended by the water pump? 2) Could have green previous fluid reacted with green new fluid? And this is the effect of gelling up? 3) Could the new fluid act as a wash and pick up dirt/rust from the inside? 10 years worth of stuff. I believe its an alluminum block. 4) maybe air pressure blown into radiator cap created a hole in the block or transmission where oil is now getting mixed with coolant? 5) Other possibily? I will right away flush it with tap water in case its the jelling up process. What steps you think I should do?
What are your thoughts on this scenario : I bought HOAT mixed it 25% with water as per bottle instructions. Added about 200ml to my OAT system as a top up. Am at risk of gel or will it be OK?
Hey what happened ? Asking a month later hopefully it went okay with u I think I finally found someone ( you ) in-which whom is in thee same exact or very similarsituation I am currently in ..... @@graemecrawford1639
so white dirty thingy can be mixed coolants? Brand new motorcycle and fluid level was below min. so I added random coolant and later found bad things under radiator cap.
My coolant reservoir was empty in toyota I filled it with the recommended pink coolant but when i open the coolant cap the coolant was green is it going to mess my engine up or its ok?
Hi so I bought a 2006 Scion tc and had green coolant already on, but I went to an auto parts store and gave me a red/pink coolant he said that’s the one that should be on there it says Toyota on the bottle should I drain green and replace with red/pink or keep green?
I'm not sure what type is in my 1999 jamboree GT E450 Super Duty RV. Can l just add water in case it needs to cool. Rv is not having a problem but I just want to be prepared since l am going on a 400 mile drive.
I have an 2014 Infiniti G37 s coupe. I had my radiator replaced, and now I need to top off my coolant reservoir. I’m not sure what coolant they used, and it’s at the Min. Line. It looks bright green I called and asked the shop what coolant to use and someone advised me to get Prestone all vehicle coolant. For my sense of comfort and peace of mind can you confirm this is ok to do please? I plan on flushing it and going with OEM Nissan blue coolant, but have a long drive before I can do so.
HELP ME....I have a 2015 Honda CRV , I added Prestone, green, a little to my coolant resovoir, and it was too late when I noticed it had blue coolant in it....Am I okay?
@@Top5AutoRepairs Thank you sir, you wouldn't believe the automotive people told me I needed to flush my radiator out. Going with you....thanks. Might do a video on this.
I'm confused. I have a 2006 Hyundai Azera, bought from the second owner. the first owner filled in yellow antifreeze, but almost everyone tells me that I need green, some say yellow
I don't worry about such things. I don't live in a cold climate so I don't need antifreeze. I have never ever used anything but pure water in any of my vehicles. I have never experienced excessive corrosion. My engines run at Perfect temperature. There have been times when I have drained the water after 2 years and not noticed any more corrosion than when I used to use antifreeze. So, if your vehicle is never exposed to freezing temperatures, don't bother with antifreeze at all!😊
Sorry I know this is a dumb question, I heard from a store person saying you can mix universal coolant with any other coloured coolant, is it true? I just want to make sure thanks.
Hoat is the most balanced coolant. You can top it off a little bit of anything. Thats why the answer is yes and a no if incase of emergency. But regarding dye color it doesnt matter will look sht long term though. Been using different color same technology flush it properly
So two different brands or colors can be mixed IF you know they are both the same type (IAT, OAT, HOAT)? I just ask because I found cooking that is OAT but is a somewhat yellow color. My car is a 2019 and needs that but, the existing coolant is pink or orange looking.
Ur videos are great, i have a question iv always used dexkool on my chevy truck, is it okay to use prime guard brand 50/50 prediluted anti freeze coolant for all vehicles my truck year is a 2006 silverado

So if two coolant are different colors but have same technology (e.g: ethelyn glycol) i can mix those 2 right? but if one has silicate it cant?
Great simple explanation of the coolant differences and what matters.👍🏾👍🏾
I tell you, mechanics with foreign accents seem to be the best mechanics
Very good explanation, and helpful even for an old guy like me.
Do they make a test strip to test if they were mix or to identify OAT and IAT.
So how do you know which to use, if the coolant jugs are not labelled IOT or OAT or HOAT ??? Great video none the less.

In some ways.
So if u can't mix them together what's the point for HOAT isn't it mixed?🤔
Hoat is the most balanced coolant. You can top it off a little bit of anything. Thats why the answer is yes and a no if incase of emergency. But regarding dye color it doesnt matter will look sht long term though. Been using different color same technology flush it properly
They all use aluminium radiators so why protect the engine leaving the block in phosphate base coolants?
I wanted to get information on universal coolant, but you didn't say anything about it.
The hoats and oat coolants that I have compared have a 15% difference in boiling point.
Surely PRESTONE all vehicles coolant can be mixed with any of the older technologies as the manufacturer guarantees it mixes with everything
So two different brands or colors can be mixed IF you know they are both the same type (IAT, OAT, HOAT)?
I just ask because I found cooking that is OAT but is a somewhat yellow color. My car is a 2019 and needs that but, the existing coolant is pink or orange looking.
