[@rafaelfigueroa2054]

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).

[@steveberkoff3473]

I always have more confidence on auto repair after listening to and watching your clear, easy to understand videos. Thanks Scotty!

[@thekidd2013]

I have learned so much from your videos. I feel better prepared to understand what is happening with my car and when I have to deal or talk with my mechanic. Thanks Scotty. Will be watching.

[@robclose7964]

I love how Beavis and Butthead pop up when you mention “the 90s”

[@AngelJimenez-yw5mp]

I love these history lessons, thank you Scotty!!

[@keithchhieng44]

I’ve learned a lot from this classic mechanic and he’s being honest to million watchers on KZbin. That being said I’ll hit that subscribe button and the bell. Thanks Scotty😀

[@illuviium]

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

[@bum153]

Scotty you have inspired me to be more intrested in mechanic's. Thank you

[@scottykilmer]

glad to hear it, thanks!

[@southjerseysound7340]

You should check out South Main Auto's channel. Eric O really does some great in depth stuff that would help you

[@bum153]

[@Spitfireseven]

I've watched countless videos by you and your videos are recommended by many others. Just love your stuff Scotty!!!

[@darrellknox6435]

Scott, your show is the most valuable to a driver or mechanic I be ever seen on the web or television. thank you so much for what you do.

[@incrediblesloth85]

That was super informative. I didn't know that. I knew about the green and dexcool and such but the HOAT stuff sounds pretty neat. This is one of my favorite channels. I learn so flippin' much. Thanks for making these videos, Scotty!

[@scottykilmer]

thanks for the support!

[@ah-yp6vp]

+Scotty Kilmer its scotty kilmer wats up dude haha

[@somepuertoricanguy5668]

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

[@lovemind8466]

I'm loving this, I will be a car genius after learning all the great tips from your channel..

[@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]

Hi do you think Toyota coolant is better FL-22 Mazda coolant for Mazda CX-5 2913

[@iancalleja3898]

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

[@elitavarez8987]

This channel has been so helpful to me. I've gotten through some tough times on my vehicles because of you. Keep it up. Your awesome bro.

[@alexandercopeland5087]

I just want to say I have been a mechanic for about 16 years and here in the past couple of months learned a lot more, Thanks so much Scotty!!

[@jamespitman3710]

HOAT is wonderful stuff. Love it in my cars. My poor jeeps never seem to keep coolant systems intact long enough to run it.

[@tampabaybuccaneersfan7904]

Those old 4.0's were basically a tractor engine dropped into a Jeep, a ton of torque with bad gas mileage and they leak oil like crazy.

[@jonguitar102181]

Scotty - I love your videos. Congratulations on all your success and thank you for being so thoughtful and informative - You Rule!

[@10thFTW]

Lots of subs within the last year! Congrats scotty.

[@artreyes2724]

Scotty not gonna lie I came across by you on accident recently but every since I been watching your videos it make me understand more about my car that I just got from my uncle and let me tell you this there a lot of problems with it

[@davidmclean8535]

Thanks Scotty David here from Australia you have helped me a lot. All the best.

[@fourocker]

I knew this stuff already but had to watch because it's so much better coming from you than inside my head, you the man Scotty, good info 👍

[@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.

[@Evidince]

Your channel has gotten so much better over the years. Keep it up Scotty

[@girohead]

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?

[@HippieSkippy100]

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

[@DonWood1]

I love/hate these videos. I love the learning (HOAT? Who knew?), I hate the growing list of "I could do that myself" chores. :) Thanks for all of these.

[@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!

[@c6e9]

Thanks for clearing this up, Scotty! Good video - clear and to the point.

[@joeianniello]

Thank you Scotty!! Watching your video's is like going to Automotive college!! Love them!!

[@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]

sully676 exactly. Thanks t seems to me if you change the fluids in your car every several years, the amount of problems goes way down.

[@ppodhajsky1]

I learned so much on this one video! Scotty, thank you for the great videos!

[@Scoutss21962]

That was one of the best explanations of coolant types I have experienced.

[@darrellpatton3549]

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 👍👍

This is an excellent chanel to learn about cars and how to keep everything running nothing better than some one from the old days explaining how things were made back in the day compared to how they are made now and to keep up with the newer models running longer And when they do break down everything you need to know about changing parts and servicing is right here thank you so much from cape town south africa

[@matthewshambler2644]

OAT technology is great! Still worth changing every few years though.. Lack of cooling system maintenance is a major cause of breakdowns and expensive repairs. Thanks for the history lesson Mr. Kilmer:-)

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]

simon lloyd problem?

[@Teezjunk]

Rude comments👀🤔👎

[@girohead]

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.

[@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.

[@dawn9340]

The pink coolant is also known under the “Pentosin” brand name in Germany. This is the ONLY brand recommended/required coolant for Audi engines. Great video as usual Scotty.

Great info Scotty! I just had to replace my rad in my 2014 jeep grand Cherokee after 196000 miles. I made sure I used the organic oat like you suggested😊 thanks!

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"!
