Coolant Additives

[702L32]

if you have used in the past or are currently using one, which one and how did you like it?

Im looking at these three so far, in this order.

DEI Radiator Relief


Royal Purple Purple Ice


Redline Water Wetter



the DEI got good reviews and beat out the Redline one in a turbo mags comparison. they didnt have the purple ice in their comparo though. I can get all locally with the Purple Ice being the most expensive


a few more on the market are

Lucas Oil Super Coolant


Hy-per Lube Super Coolant


Flex Lites Flex-A-Chill


Mishimotos Liquid Chill




while all these claim anywhere from UP to 20 - 30 degrees cooling ability i'll be happy with atleast 10-15 degrees.


this one claims up to 40!

I use the AMSOIL coolant additive, opperating temp has been below normal/middle of guage. car also warms up faster which I like !

About those additives, I can almost guaranty those claims (even if accurate which I doubt) are with water, not coolant. There is a difference and you wont get those numbers on your car! They could also damage the engine in the long term with their ingredients.

So should we avoid these if it will damage the engine? I'm all about an additive, somebody enlighten us with some knowledge......

I've tried Royalpurple in my old 1986 Camry I think. Didn't make a difference. Ended up replacing thermostat after.

i think these things work best with only water. the greatest results reviewers have had are with the water only. with the 50/50 blend and the additive it was very minimal difference maybe around 5 degrees cooler. im still willing to try one of these out though. with the hot ass summers here in vegas every degree counts!

I tried the Redline Water Wetter in my 64.5 Mustang. I didn't really notice a difference. But it wouldn't be fair of me to blame it on the product. My Mustang always runs hot, mostly because it has about 11:1 compression. Plus the radiator is probably too small for my engine setup, and I can't seem to find a fan shroud that fits properly. What I REALLY need is a larger radiator and a proper fan shroud, and / or electric fan(s), and maybe a lower temp thermostat.

i was just about to purchase some Redline Water Wetter soon. not to long ago, i had checked the Amsoil website for coolant additives, since i use their motor oil, but didn't see it. now i see it is under maintenance, and not cooling

i read great things about the Redline product, but Amsoil out performs it. i'll be getting some Amsoil Coolant Boost now

Amsoil is the shiznit!

Yah, but water is real bad on corrosion for our engines, as well as the fact the car will run hotter then with coolant. dont run straight water, thats my suggestion if ur serious bout it...

Lol, Damn right !! I love their stuff and consider them the best for some fluids. I dont burn a drop of oil period!!

I used water wetter in my old 79 Ford F-100 when it was overheating. It actually helped out 10F or so. Ultimately didn't fix my problem as I needed a larger radiator and proper fan.

oh no intention of running straight water. im just mentioning that the tests i read with the highest drop in temps, didnt use any glycol/antifreeze in the mix. just straight water and the additive.

running straight water or water with like the water wetter is required on race tracks. besides the fact that water transfers heat better, im thinking that its also a safety precaution. if u had the antifreeze in and you bust a hose or whatever and that shit spills all over the track, it may cause people to crash more then theres the toxicity factor of it contaminating the environment

but thats how these additives work by reducing the surface tension of the water allowing it to transfer that heat better. the anitifreeze is mainly for not having the water turn into ice in your motor during the winter, along with the rust/corrosion protection it provides . it also raises the boiling point of the water in the system and doesnt make the car run "cooler" just not overheat as easy

I use ALL of the one listed by op.

The harder to find on shelves and more expensive, the better.

[gameguru1360]

so they all work with the coolant already in your radiator??

did you have a favorite or preference?

yes they all will work with your current coolant blend. just not as much as with just straight water according to test results ive seen. cant hurt for sure

[fishbone]

I apologize, I was being sarcastic, as in, I am using ALL of them at the same time
All of those products will do what they claim. Whether or not they are needed is a different matter. Plain old coolant/water mix will do fine. Oil cool is not needed since oils have their own additives and if you have to add it to keep the oil cool, it's a band aid solution to a bigger problem that if left unresolved will probably kill an engine.
Since you are in Vegas and oil/coolant temps are a concern, try out what you have available and see what it does. For oil I can almost guarantee that if you want lower temps you will need an oil cooler.

my biggest problem right now is that my CVT is overheating. it gets up to 290F. the service manager at nissan is dodging me and not calling me back to meet up with their corporate tech. he actually had the nerve to tell me that thats normal
