Nice job Lyle, keep up the good work

There is also pink and purple coolants which I use in my German car. It seems they always want to complicate things.

Great video Lyle.

Was about to do coolant flush on my 94 c4 you answered my question green it is

I bought a 2007 last summer and it had green coolant as well as a ruptured radiator. I replaced the water pump and the thermostat had some crazy jelly build up, it was so crazy looking! I did the hoses, radiator, water pump, and reservoir so she is running great now! thank you for your videos!

I stopped by for another trivia question. Rats!!

Helpful information as always - thanks Lyle

I'm retired from 47 years in the car repair business. The Dexcool is a great coolant but has one bad flaw. If you let the recovery bottle get empty due to a leak and don't catch it, within in a matter of months the Dexcool will react to the air in the system and turn into a thick red mud that will stop up your radiator and heater core and that is almost impossible to flush out. With a Dexcool engine it is imperative that you keep a close eye on the recovery bottle and keep it full. Green coolant does not do this.

I always wondered the difference. Now I know.

I put orange coolent in my 85 firebird when i was teen and luckily the water pump blew up that same week

Great advice as always.Thanks

Good to hear from you thanks nosale 🙏🏾

Another great informative and educational video. Thanks for helpful info! 👍👍

Excellent post Lyle, and it was great seeing you again this year. Same time next year sir!!

I like 👍 the green fluid 😊

That’s a great piece of advice. Thank you very much

In the movie Red Dawn, they used yellow.

For awhile, I have been wondering about coolant , ever since I learned about " lifetime coolant" and wondered if it offered the advantages of a new formulation , or if it was even compatible with my car. I guess I was overthinking it.

Doin the Lawds work! Thanks Lyle

I use green prestone in everything Corvette Nissan frontier both sport bikes 50 50 mix no problems

It's not a huge deal either way in the LS motors. I've used green and orange for many years and many miles with no issues. This is probably one topic that gets overplayed a little.

Thanks 👍

So my question is, if '95 and back is green and modern LS engines are orange, where does my '96 LT4 fall?

Lyle, in my opinion, the best coolant for any car regardless of year is Evans Waterless Coolant, manufactured by Taylor. At $45 a gallon, it's not for the faint of heart, but here are a few reasons why everyone else should invest in it. One, it raises the boiling point quite a bit, but will not boil over. Two, it's non-conductive, meaning hydrolysis will not occur (no rust anywhere in your system). Three, it can be drained and reused, even in another car. Four, no worry about radiators and heater cores needing to be replaced due to rust or leaks. And Five, it's virtually a lifetime fill. I have used it in all my C2-C4 Corvettes with great success. Because it won't boil over, my engine compartment never looks nasty with rusty red radiator spray. I learned about this stuff on a Jay Leno's Garage TV show, and then followed up with my own research, with very positive results. I am not affiliated with Taylor or Evans in any way. I am simply a satisfied customer who wants to share his experience with the product to other followers of your C&S videos.

Does the orange Dexcool last longer in YEARS as well as miles?

Thanks for the backstory and clarification. I knew to use Orange in my C6 because that's what the user manual told me I needed to do. Plus, the stuff in the cooling system was orange when I bought the car and I'm not one for breaking tradition. Also, thank you for the English lesson. You used a word that sounded strange to me "componentry." I'm not crazy in my assessment the word is so strange that my spell-checker flagged the word as incorrectly spelled, so it is not a widely used, or known, word. I had always thought "components" were one what referred to when discussing multiple parts of something, but seemingly, my understanding is a misunderstanding. Dictionaries are not entirely clear, but as near as I can tell, the word componentry is used when there are multiple different component that are used in a larger machine. "Components" is used when there are more than one of the same component. So, componentry is correct as you used it, describing an engine's parts, and components is used when you've got a bag full of a many of a single type of component. This should, of course, have been intuitively obvious to even the most casual speaker of English. I can only fault my own stupidity and the horrendous teaching skills of my school teachers for my linguistic near mistake. On a related note, I always refer to a car's engine as an "engine," and not a "motor." Motors are electric. Engines use combustible chemicals and then ignites them. Duh. Also completely obvious to even the youngest of elementary school dropouts. Man, the Motorhead band must sure be embarrassed. I don't think those guys are even allowed to drive a car, likely contributing to their misunderstanding of words and subsequent destruction of intelligence and lowering of IQ point scores across all English-speaking countries worldwide. Cheers, and keep the rubber side down.

Hi Lyle, what about coolant for modern cars? can i use the same coolant as my VW in my Corvette? is it coolant for aluminum engines, or is there any difference between Dex-Cool and other coolants for aluminum engines? Dex-Cool is hard to find in Sweden, and twice as expensive.

I have a 2002 Corvette that i just bought with only 11000 miles. Should i have the coolant changed or just let it be?

Do you ever recommend cleaning the cooling system with a chemical cleaner instead of just draining and flushing with water? If so, what cleaner do you recommend?

How about all engine coolants? Are these safe to use? Can they be mixed with either green or orange coolants?

Great video Lyle! Thanks for sharing! God bless!

What did GM use in 1977 for coolant I use the green but did GM use something different

What brand of Dex cool is good?

Dex cool was a disaster for general motors. They couldn't make it correctly. Honda stopped selling engines to general motors because GM insisted on using that garbage. Your first state that the job of coolant is to regulate temperatures. Then you contradict yourself and explain its other job, which is to prevent corrosion.

My 1984 Corvette has orange (presumably DEX-cool) in it. Is this OK?

👍 🇨🇦

Can older corvettes use the orange without an issue if you flush out your system first. Do they "cool" the same

green is getting hard to find

I have 92 zr-1 corvette. And it got a all aluminium lt5 engine. What is the best coolant?
