RMI-25 questions

[EclipseTurbo]

I just learned about this seemingly wonderful product, I live in CA and the car never sees below freezing temperature.

I usually use 30/70 water and water wetter. The car is a DSM with fluidyne aluminum radiator.

I am just trying to understand, if I use 100% water and RMI-25,
I don't seem to be raising the boiling point of the water,

then if I shut the car off, it sounds like the water will boil..?

Also, is it safe to run 100% water and RMI-25 in CA, all season?

www.arizonaGN.com there is a write up on RMI on the side

Nick Micale will hook you up!

you need to change the RMI out every 6 months or each blown headgasket (what ever comes first for you)

in AZ none of the local guys run anti freeze. we dont run any thing else but water and RMI. i personally never see temps above 180 in the hottest summer day (115 plus)

Thanks, I cannot find Nick's number from the site, e-mailed him already.

I was wondering, in the case of a blown headgasket, if you don't catch it in time, the water does not mix with oil at all, it will hurt the engine much more than coolant, which at least mix better with oil?

conventional coolant destroys bearings. RMI does not attack the bearing surface. However, oil does not lubricate well, obviously, when diluted with water. Therefore, if you run the engine long with water in the oil, you will incur damage.

We ran RMI in the race car with distilled water,when we pulled the radiator it looked like crap! I use Redline water wetter in my car and it seems to work ,at least the cooling system LOOKS good.

In over 10 years of using RMI and knowing LOTS of people all over the world using it, first time I ever heard a comment like this?

Since you only use 4 letter words it would be hard to make a comment about why this is happening. As far as Waterwetter, it does not contain non-corrosive additives and will eat through your radiator in time.

Think about this for a minute or so; WW has no cleaning ability so the fluid looks clean, RMI cleans constantly and keeps foreign material in suspension. Now if the radiator looks like "crap" now, it must have REALLY looked bad before using it.

Not to mention that it pulls the slime out of the water passages that has built up over the years. That is what it is supposed to do. Those that are interested should read some of the online info on RMI-25 and discover that one of its features is to hold the slime in solution rather than allowing it to be deposited either in the water passages or in the radiator tubes where it would normally harden and prevent adequate cooling.

Straight water wetter usually results in rust and early water pump seal hardening.

Eclipse, with regard to your question on boiling, a 15# radiator cap raises the boiling point of water by 45 degs. Depending upon your altitude, this puts the boil over point to somewhere around 255 degs.

I don't know what radiator temps you normally run but I would hope they are no where close to 255

If you don't have to worry about freezing temps, then distilled water plus RMI is an ideal mix. 8 ozs per radiator fill. As it may dislodge build up which you can see by looking into the opening, it might not be a bad idea to flush the radiator out with water and refill after a few weeks. If it is just a little, then overflow the radiator and let the slime wash out.

Altho it has an excellent lubricant package in it, I would suggest draining and refilling every six months.

Here, where it freezes, I add it to the antifreeze to prevent the antifreeze from depositing silicates into the radiator tubes when I add coolant in the fall.

It's one of the cheaper things you can do to maintain the cooling system and its performance.

In as much as you have thing for four letter words maybe a better a choice instead of crap would have been diarreha.
When we started using RMI this was a NEW set up .BRAND new Stage motor brand new Scirrocco radiator. Mixed the RMI per instructions with distilled water. The only reason I can think of that may have caused this was we didn't change it for two years.

Yes, I will be using a higher pressure cap,
but I'm concerned when the car is shut off. The coolant is not moving, wouldn't the water inside the head passages start to boil?

 

[TURBOV6]

This stuff WORKS!

I seen 10-15 degree drop in the temp. Just make shure you shake the bottle good before use

Also I had a question......I did not have distilled water at the time so I uses tap water. The water here is pretty clean and has no chlorine in it. Should I flush it out and use distilled water?

Don't see why. It should not be nearly hot enough to boil. I have been using it for years with no problem. Stock radiator cap at 15# is all you need.



TurboV6....don't worry about it. Go to the store and buy some distilled water the next time you are going to change it.

Everybody I know calls Water Wetter - Barnical Builder, because it will build up scales on the radiator.

Did you follow instructions?

RMI is to be replaced every 12 months maximum. You'll find most vendors recommending 6 months because of switching from freezing to non-freezing months. You ran it twice as long as recommended, and this with a Stage motor no less!!! Try that with ANY of the vital fluids in your motor and see what kind of damage is done. How many people change oil every 7,000 miles? None that I know of that still have a decent running motor. The cooling system is just as vital as the oil, yet is probably the most neglected system under the hood. You must follow ALL the directions, not just the ones you want to follow.

In two years it probably had one hour running time max. The car is kept in a heated, air condition shop. We must be doing something right blew one headgasket in two years and THE fastest qualifier where ever the car goes.

I ran water + RMI25 in my chevy truck 350 V8 during summer, and it did develop brownish residue in the filler neck, overflow tank, etc.

Is this what you mean by "crap"? Others on the board told me it was normal. No evidence of rust, clogging, etc.

Because I take the vehicle skiing (freezing), in December I refilled it with 50% Antifreeze/Water + RMI25.

With the dissimilar metals in a motor, the cooling system is essentially one big battery. This being the case, whether a motor is run or not, the chemicals that protect the cooling system components eventually break down. This happens regardless of the environment the car is stored in. That is why cooling systems need at a minimum yearly maintenance. Since this chemical breakdown is a slow process, even cars that are run daily can have a degraded cooling system and it go unnoticed till it's too late. Just looking to spread the word of the importance of cooling system maintenance.

The brown residue is RMI doing its job, cleaning and keeping the foreign material in suspension. This is why it is recommended to flush the cooling system twice a year. Even a "new" block that has been rebuilt and hot-tanked has lots of stuff left in the cooling passages.

Another procedure on using RMI for the first time is to check, and usually flush the system after 500-1000 miles since lots of crud is initially removed.

HurstGN and a couple others who posted here sound like they read an article on cooling I wrote about 10 years ago!
