thanks scotty for explaining best. have a 2016 dodge grand caravan. it uses this hoats. now i know. thanks.

[@MisterLepton]

Scotty Kilmer so the “inorganic” and “organic” refers to the additives only. After some more reading it looks like the main inorganic additives were “phosphates and silicates” which I’m assuming to be sodium silicate and sodium phosphate (or maybe it was phosphoric and “silicic” acids hence the name “IAT”). The organic additives appear to be sebecates (salts of sebacic acid), 2-ethylhexanoic acid or some other proprietary organic acid. The hybrid one appears to use organic acids but not 2EHA (so I guess this is proprietary?). So, you know that “liquid glass” radiator repair stuff they sell for repairing radiator leaks? It looks like that’s just a concentrated form of the additives the put in “IAT” coolants!

[@dsans60]

So I have a car with dexcool (2017 Chevrolet spark)... I know dumb decision. Anyway since this dexcool stuff is bad could I flush it out entirely and put in some of this new stuff made by Toyota or would it mess with the warranty?

[@73honda350]

2-EHA in newer cars (post 2001 or so) has been shown to cause leaks in their silicone-based gaskets.

[@iftysalim4356]

Scotty Kilmer have u ever heard of polytron. Can u talk about it? I heard tht they r gud for the engine. Is tht gud?

[@hayleybutler4134]

I just went and purchased genuine Toyota coolant “the pink stuff” because I just realised that the local mechanic didn’t do it when I had my car serviced. All my local stores had green coolant. This video reinforces that I made a good choice. I’m dumb when it comes to cars, but you’ve taught me so much!

[@gregfarnsworth829]

Scotty is spot on with the coolant. As a ford mechanic, I had a Taurus that kept coming back with a leaking heater core. I replace it 3 times in a year. Came to find out that the electricity it created would corrode the heater cores and eventually cause them to leak. (had to add a ground wire to the recovery tank).

[@branzeirr4l216]

[@Johnslist]

THANK YOU! I'm a proud DIY owner of a Toyota with 155k miles (do my own work thanks to you), and thought it was about time to do fluid. I thought I read in the manual that it didn't need to be changed, but assumed they didn't expect someone like me. This is the best review I've seen by far and I've been searching auto repair forums and am now amazed at how many 'techs' had no mention of this, even when I asked the difference (between the pink and the green stuff). My only question now is if I can find a good alternative to genuine Toyota fluid which is twice as much out here. You gotta be crazy to let these shops touch your car. I started doing my own stuff (again, I did as a kid) because I was tired of the upselling: 'When was the last time you changed out the air in your tires? We recommend that with every oil change'....GONE.

[@sethasher1498]

Wait, do you have to change out the air in your tire frequently?

[@F.Krueger-cs4vk]

Always used Toyota anti freeze/anti boil long life coolant concerntrate/red colour. Mixed 1 part to 2 parts water. Never noticed any corrosion, hoses stay soft, change every 2 years, system always clean. 👍🏻 🇦🇺

[@snackyxchan]

Working on Toyotas I can tell you the hoses last, not sure if it's the rubber they use or coolant but they seem to last alot longer and stay softer than other makes

[@F.Krueger-cs4vk]

@@snackyxchan i use Toyota coolant my other vehicles. Mazda, Ford, Diahatsu, MB willys jeep. All their hoses are soft, cooling systems clean. 👍🏻

[@iancalleja3898]

So do you recommend I can use the Toyota anti freeze on any car I got 3 cars to charge the cooling system

[@neolectric03]

I haven’t replaced Toyota long life red since timing belt and water pump was done in 2011. Taco 2000 here

[@NintendoMario246]

Just recently changed my coolant out on my 2012 Toyota Tundra. Did it myself. Very easy job! Rather pay the additional $3-4. Versus paying $200+ for a mechanic to change it out. Thanks for helping me save money over the last several years!

[@saabstory4778]

I personally use Zerex G-05 in my car. I also really like to change it far more often than recommended even though it may be a waste. I do a full flush when I first buy a car and then another every 1-2 years depending on how hard its been driven. I just like to make sure the system is clean because I'd rather replace coolant every year or two than hoses, thermostats or water pumps every 5 or so years.

Dude this guys KZbin channel subscription number is an indefinite reflection of his easily likeable atmosphere. Not only is he overwhelmingly informal, his delivery is straight forward and somehow manages to define the various functions of a multitude of different car appliances , he manages to do it in a very organized fashion and all of a sudden you have a complete understanding of the different types of coolant there are and how it’s evolved over the years to increase performance

[@VictorDunkle]

The chemistry of coolant is a very interesting topic to study.

[@rbeck3200tb40]

It sure is mix the green coolant with diesel fuel and put that mixture into a super soaker water gun then light the end of the gun with a small flame . What you have there is a home made flame thrower . Try it .

[@poiiihy]

even all the HOAT coolants etc have different ingredients!

[@poiiihy]

rbeck3200tb40 what good is the coolant? why not just use diesel alone, or mix with water if necessary... ethylene glycol is poisonous

[@DixieNormous6625]

First time I've even hear of HOAT coolant, thanks Scotty.

[@sully676]

huge believer in changing all the fluids in your cars, not just the engine oil, great video

[@TheFrenchPug]

sully676 Especially coolant! Did a head gasket job on an old Mercedes that was not maintained, ran hot, and head gasket blew. Got head off and coolant passages were plugged up with severe corrosion. Only one path was partially clear. Cleared em all out and put everything back together and I could hear the engine thank me when it all ran through the first time.

[@sully676]

another example of neglect costing more than maintenance

[@crow-vz5lx]

sully676 yeah. Super weird when i talk to people, and they seem to not be to concerned about any other fluid.

[@marksuave25]

You talking about Grandpa brought back memories. I remember my dad used to always change the antifreeze in his old Caddy. Thanks for the info. I would like to replace the coolant in my 2001 Camry to the HOAT formula. As a woman, I want to do everything that I can do to avoid having to take my car in to the shop for repairs. I have learned so much from your videos. Thanks again.

[@Teezjunk]

Rude comments👀🤔👎

[@Johnslist]

The 'as a woman' comment is outdated and cliche. Those shops are equal opportunity. They will upsell, lie, cheat and swindle anything that walks in. Including my Dr. Brother-in-Law, my sister or my engineer self. AND STAY AWAY FROM ANYTHING "FREE" - NO FREE BRAKE INSPECTION, NO FREE ALIGNMENT INSPECTION, NO FREE FLAT REPAIR, AND NO FREE CHECK ENGINE LIGHT - those are merely authorization requests for a $1000 "necessary minimum service." If there was ever an industry that need to be decimated it was those guys.

[@Teezjunk]

girohead I appreciate your advice/opinion. However, I can only accurately speak of my personal reality and life experiences. So, for me the term; "as a woman" is today and will always be both timely and relevant.

[@jimmyross4352]

Tee Jay I think both you and girohead make good points. I have experienced his ''equal opportunity'' shops, and I suspect you have experienced crooked men who don't know about the law of return, so consider it an advantage to seek refuge in the bias and illusion of chauvinism.

[@MRSketch09]

If you want to cause yourself a headache, mix coolant types, I did that in my truck. . . I end up pulling and replacing the radiator out of desperation, flushing the system multiple times, in the WINTER TIME.. just to get my heater going in the truck again. When I went to the auto store, they only had the orange coolant, on the bottle it was "long lasting", I was like what could go wrong? WELL in my truck manual, I read this AFTER the fact,..its like "Only use green coolant".. Ford Ranger Manual, anyways, there was a very valid reason for that. Mixing them, gunked up everything.. *Sighs* what a hard lesson to learn.

[@Rhaspun]

I have that happen to an associate of mines a few years ago. He mixed his coolant when topping off his reservoir. He ended up with clogging up his radiator and having to get a engine flush done.

[@thatgray24v24]

Edgar Arriola Mopar uses the pink HOAT coolant too. Same pink color.

[@QuantumRift]

You may be a mechanic but you should have known about Evans...... www.evanscoolant.com/. Evans IS the best. No WATER. NO changing. EVER. No Corrosion! Water is the root cause of corrosion in engines, eating away pumps, radiators, liners, etc. Current antifreeze formulations regularly fail to prevent corrosion. Evans waterless coolants prevent water-caused corrosion in a cooling system. The Science of Corrosion When heated, water releases a significant amount of dissolved oxygen, but as it cools it reabsorbs fresh oxygen. This cycle leads to the corrosion of metal, which is accentuated in classic vehicles with no expansion chamber. Water also acts as an electrolyte if dissolved solids-such as hardness salts (lime scale)-are present. This promotes galvanic corrosion, a process in which two metals corrode at different rates, often causing pitting. Other Antifreezes Corrosion inhibitor formulations have changed many times over the years, but not always for the better. Nitrite, silicate, borate and azole based products have been around for many years, with Organic Acid Technology (OAT) inhibitors appearing more recently. OAT formulations are often branded as “long-life” based on their five-year lifespan, compared with one to two years for standard antifreeze formulations. Although OAT-EG-water mixtures are now used in most new car engines, they have proven less successful in older vehicles and heavy duty diesel engines (HDDE). After several years of trying OAT-based products, many HDDE OEMs and fleet operators reverted to nitrite and/or Hybrid OAT (HOAT) formulations. One reason for this U-turn was that OAT formulations offer little protection against liner pitting. To maintain effective inhibitor levels it is often necessary to retro-dose with Supplemental Coolant Additives or SCAs. It is common for SCAs to be under- or over-dosed, leading to accelerated corrosion rates, cylinder liner pitting or the blocking of radiator channels with congealed inhibitor. The Evans Coolant Solution Evans waterless coolants contain little oxygen and are comparatively poor conductors in comparison to water-based antifreeze, so metal corrosion and coolant degradation is eliminated.

[@NotSoCrazyNinja]

Just checked the price of HOAT coolant, it's about the same price as regular coolant. Plus, if you only have to change it half as often, that means it's actually cheaper to use than regular coolant. I'm switching to HOAT when I flush my coolant in a couple weeks.

[@Kimberly1Lily]

[@solomon-uu5xh]

PLEASE READ THIS EVERYONE ! If you use RMI-25 Cooling System Treatment you will NEVER have to flush your cooling system or change your coolant EVER AGAIN !!! RMI-25 cleans the entire cooling while you drive ! Cleans & coats ALL metal surfaces ! Treats all seals, valves, hoses & rubber components & more than doubles the life ALL cooling system components !!! RMI-25 is ORGANIC BASED, NON TOXIC, 100% BIODEGRADABLE & safe to use in environmentally sensitive areas.100% compatible with ALL antifreeze antiboil solutions & metal based stop leaks or can be used with water only in temperatures above 5 degrees celsius (41 degrees farenheight). RMI-25 used for nearly 40 years worldwide & still the world's number 1 cooling system cleaner, coolant & treatment. "A test of the RMI to the ASTM 4340-89 standard shows that it's Heat Transfer Corrosion Rate was only 0.011 mg/cm2/week, almost 100 times less than the requirement of the standard." Pour it in & drive away !!! The only product that cleans protects & lubricates while you drive.

Back when I used to have problems with my Ford van overheating I found a product called "Wetter Water". It was a coolant additive that claimed to make the water a better conductor of heat thereby keeping the engine cooler. It actually worked. I've always wondered what was in that stuff.

Thank you Scotty for clarifying the difference between IAT, OAT and HOAT, and which is the best. Succinct and clear. Any suggestions on how to purge dexcool sludge from the coolant system? I've been so frustrated I had decided to attempt to flush and clean my car's coolant system with the hope of going to the green coolant (IAT). But now, you've convinced me that is not the best "solution"!

[@videomaniac108]

In my old Porsche that had a liquid cooled engine, I would use a mixture of Redline's Water Wetter plus distilled water and flush it once per year. This, plus the use of Redline's full synthetic ester-based motor oil, improved the heat transfer in my engine so much that the engine temp would never go above the thermostat temp regardless of the engine load or outside temperature. An added benefit was that it helped cool my oil and keep the oil pressure higher when the engine was at idle. The drawback with this stuff was that the anticorrosive additives would wear out faster in an all-aluminum engine, which I had, and had to be changed more frequently. Also, there was no boiling point elevation or freezing point depression so I couldn't use it in a climate where the temperatures would dip below freezing. This was not a problem since I lived in San Diego at the time. The car had an extremely high-pressure cooling system pressure and so the water's boiling point was sufficiently elevated that it would never boil.

I really hope that people watching this video paid special attention to the "do NOT mix" different types of coolant.... they are NOT interchangeable fluids. I a 30 year veteran of the profession and have seen some horror stories from mixing coolants... mostly from people getting those "cheap" oil changes at those quick-lube, or as I call them quick-butchery shops. (i.e. the coolant solidifying in the coolant passages and plugging up heater cores).

[@teravolt6113]

A supermarket near me only stocks the green coolant. This is a big no-no. It makes most people assume that it fits all cars... i myself got away with mixing GM's Dex-Cool and two other OAT coolants however, but that's because i know what OAT stands for. Most people just don't know and when that overflow tank is low or that light illuminates, they pick the first coolant they can get their hands on and happily pour it inside...

Toyota's SLLC pink is an HOAT that contains small amounts of phosphate, not silicates and it has to be changed first after 10 years !!.

Vladimir the pink one has a much longer life compared to the red one.. it may worth the price difference. But if you don;t mind changing it more often.. just go with Red.

[@bryanmarett1662]

I'm glad to see somebody agrees with me. The number of people who don't think coolant so important is astonishing. Thanks for keeping it real man.

[@janiceanmary3984]

How about a detailed video on flushing the cooling system the right way? Maybe doing it on a great old American car like the Crown Vic. There are a lot of them on the roads. (I do not own one).

[@TheFrenchPug]

Janice Anmary If you go to Auto zone and buy the kit, it is really easy and self explanatory. I had never done one but the kit helps force out all the coolant hanging out in the bottom of the engine which is critical.

[@cjeam9199]

Black Buick Ah yeah that sounds like it might work.

[@SgtJoeSmith]

Janice Anmary get couple bottles of Prestone radiator flush and few gallons of distilled water. Drain radiator. Dump 1 bottle of flush in. Fill with distilled water. Drive a week. Repeat with other bottle of flush and distilled water and drive 2nd week. Then drain and fill with coolant and distilled water mixture. As long as its not winter and freezing you can go couple weeks on just distilled water. The antifreeze keeps water from freezing and has rust inhibitors. Doesn't really affect boiling temp.

This is fascinating. Never realized how the coolant can be just as important as your oil. Thanks Scotty!

[@titusfive]

Apparently the Toyota brand pink coolant does not have silicates in it unlike the Pentofrost you mention (but I see Pentofrost does come in a no-silicate HOAT version.) Thanks for the informative video.

[@ghost-4230]

There’s Pentofrost A1 Red (with silicates) for Toyota’s 1985 to 2005 and Pentofrost A4 Pink (without silicates) for Toyota’s 2005 and after

[@MrMschoose]

Great video. Toyota coolant is amazing. No corrosion.

[@titanicwhiz]

What about "Evans Coolant"? Water-less, life of the car coolant. I know Jay Leno uses it and loves the stuff since he never has to change it.

[@nutz4gunz457]

It good for cars that sit for a long time and don't get driven often but it doesn't cool as well as water mixed coolants so there is a higher chance of over heating.

[@timramich]

Nutz4Gunz45 Jay Leno mentioned that it tends to show it's running warmer because it has better surface tension and thermal conductivity properties, but it won't boil, which is the killer in overheating.

[@oldtc2848]

Evans coolant is garbage. It shows that it is running hotter because it is running hotter. It can absorb higher temperatures before it boils but it is poor at transferring heat compared to water or mixed antifreeze. So it heats up but does not cool down. Tests done show engine block, cylinder head temps all higher. It acts similarly to straight antifreeze. The more antifreeze to water the less heat transfer. Look it up, nothing outperforms heat transfer from straight water. Many classic cars from early 1900's overheat very easy running Evans coolant. Note the engines overheat but the coolant does not boil. kzbin.info/www/bejne/n56vZZ6Hbr1pp5I

[@jessegotowork]

yeah i heard the workshop say it was great at overheating engines :)

[@salvatoreshiggerino6810]

I checked the Jay Leno video. It's a scam. The snake oil salesman says you can drink it but won't prove it. And for good reason, it contains ethylene glycol: www.hrpworld.com/store/media/media/manufacturer/evans/pdfs/Evans%20High%20Performance%20Waterless%20Engine%20Coolant.pdf Looks like it's just some variation of OAT or HOAT coolant that they just tell you not to dilute. It won't work very well, just get normal HOAT coolant like Scotty says.

[@ATLfletch]

Wow. Thanks Scotty, great video. I wasn't even aware there were different types of coolant like that, and I've been around cars my whole life. Boy do I feel silly. Live and learn, right? Thanks again and keep them coming.

[@villafontananorte]

Hi Scotty, you made a mistake. Honda recommends using an antifreeze that is NON-SILICATE. Read your manual people!

[@aboelsofalabed1588]

You are 100% right.

[@lukeskywalker354]

That is True. Toyota alsobhas no Silicates. Scotty do your homework first. Just like the previous commitment said. Go by what your manual says. Scotty is wrong when he says go ahead and upgrade. If your car is still under warranty. Only follow the manual. The dealership will find anything to find fault.

[@solomon-uu5xh]

PLEASE READ THIS EVERYONE ! If you use RMI-25 Cooling System Treatment you will NEVER have to flush your cooling system or change your coolant EVER AGAIN !!! RMI-25 cleans the entire cooling while you drive ! Cleans & coats ALL metal surfaces ! Treats all seals, valves, hoses & rubber components & more than doubles the life ALL cooling system components !!! RMI-25 is ORGANIC BASED, NON TOXIC, 100% BIODEGRADABLE & safe to use in environmentally sensitive areas.100% compatible with ALL antifreeze antiboil solutions & metal based stop leaks or can be used with water only in temperatures above 5 degrees celsius (41 degrees farenheight). RMI-25 used for nearly 40 years worldwide & still the world's number 1 cooling system cleaner, coolant & treatment. "A test of the RMI to the ASTM 4340-89 standard shows that it's Heat Transfer Corrosion Rate was only 0.011 mg/cm2/week, almost 100 times less than the requirement of the standard." Pour it in & drive away !!! The only product that cleans protects & lubricates while you drive.

[@muzicsean76]

Toyota does say to use a NON- SILICATE, ethylene glycol w/ HOAT technology which is a combination of low phosphates and organic acids. So to my knowledge the "Pink Toyota Super Long Life Coolant" or "Zerex Asian Vehicle Coolant" fits these specs. So i believe you were wrong when you said that the "pink coolant" has Silicates in it as to my knowledge it doesn't. So you might want to correct this statement. (please dont mix up the red coolant with the pink, i was told one is IAT(inorganic acid tech) and the other is HOAT (hybred organic acid tech)

Since I have been watching your videos I think that you are the best informative mechanic that I have found you have not a lot for the viewers and I really appreciate you taking your time out and doing what you do may God bless you 👍👍

[@kellytrimble4120]

We've had a lot of old cars over the years, but as time went on we have gotten a lot of 90s and 2000s cars recently. Something we found is that when an early 2000s car that requires HOAT coolant looses a little coolant for whatever reason, sometimes the owner, who doesn't know any better, will top it off with the cheapest stuff he can find, ie green inorganic, before he craigslists it or trades it to the dealer. When you mix the green into older HOAT coolant, under certain conditions (and I'm not sure I can specify what those conditions are, but it seems to happen in MOPAR cars a lot that still have the factory coolant in them) under certain conditions the mixture, maybe with a trickle of electricity between two dissimilar metals between the steel radiator and the aluminum block, will cause the silicates in the old HOAT to precipitate out into the cooling system, forming a really fine sand that when wet (conditions common in a cooling system) turns into a sort of grey paste that tends to accumulate in tight places where flow is a little restricted, such as in heater hoses, at the thermostat, in the bottom of the block, in the vanes of the radiator, etc., plugging up the system. The car then tends to overheat, and the more green they add, the worse it gets for a while until its all green. They do all the traditional overheating car things they can, thermostat, water pump, drain and replace coolant (with the green) and then assume it has a bad head gasket but a compression check is still good, and there is no coolant in the oil or oil in the coolant, so they assume cracked block or head and that's when they loose faith in their mechanic and dump the car on craigslist or on some unsuspecting dealer. We didn't know this until it happened to us with a car we got cheap in a three way trade. We had never heard of HOAT coolant, but knew to use the universal coolant. We eventually did a really hard flush and got a little of the paste in the bottom of the pan, and that caused us to research it. The only fix is to completely flush it with clean water to get all of the green out, then put in a light mix of HOAT and water and let it sit, run it enough for it to circulate a little every now and then, and the precipitated silicate paste will re-disolve into the coolant, slowly. Takes a while. Then you replace it all again with new HOAT mix. And the proportion of the mix is sometimes different with HOAT, sometimes 60/40. Read the instructions. And it takes HOAT to dissolve the paste, it wont dissolve in universal. Hope that helps.

[@TheEdudo]

i had the whitish precipitates also mixing a small amount of coolant, flushed it inmediately to not harm the seals on the water pump

[@esco77dsm5]

Can I use HOAT pink in any vehicle? Have a 2002 Blazer I can smell coolant outside near the truck after a drive. Not overheating. Someone put a “filter” on the upper heater core hose. They said it burst.

[@daletallyn9672]

Good day Scotty One type of coolant you missed on your review is waterless antifreeze. I have a classic car and use that because it's range of operation is much great and reduces corrosion to almost 0 . The down side of this product is its cost but it's a lifetime product. You should also add how to test the PH , acid and alkalinity. Sometimes people change far to often when fluid is good, this is my 2 cents worth.

[@claresmith7227]

Agreed, I use Evens waterless no pressure antifreeze that is basically maintenence-free and doesn't need changing. Evens claims it outperforms today's coolants in many ways. I love not having any coolant issues running a diesel. Not sure why this highend product is not out and spoken of too.

[@HonestFinance]

[@02markcal]

How does Prestone get away with the claim that it's OK to mix with all color coolants??

[@5roundsrapid263]

Prestone just started making separate coolants for the different types. They now have European blue, Asian blue, and Asian pink versions.

[@02markcal]

@5Round Rapid -- That still doesn't answer the question of how they were able to make a false claim for so long.

[@5roundsrapid263]

02markcal They still sell the “all models” coolant. I guess they think if it’s diluted enough, it’s safe.
