Flushed my radiator system today. Filled and emptied the radiator and block three times till clear (distilled) water was comming out of both (followed procedure in Helms each time regarding getting the radiator fans to come on at least twice). Then filled the radiator with a 90% water, 10% coolant mixture and put in RedLine water wetter. I then filled the overflow bottle to the max with some water wetter as well.

I started the car, ran it till radiator fan came on twice, then waited awhile for the car to cool down and added some more of my mixture (see above) and some more water wetter.

Went driving and the temperature stays at the 3rd temp mark (one right before the dead center marker); might have been a tiny tiny tiny bit above the 3rd mark. I believe this is all normal.

QUESTIONS:

1.) Should I do some sort of bleed procedure? If so what is involved?

2.) Should the temperature necessarily be lower because I went with a 90% water mix with water wetter or might it still be the same?

3.) Anything I forgot?

 

Where did you read in helms about filling and bleeding 3 times???

Anyway, I personally would have used ONLY honda #2 coolant (it's premixed, and you will need to look at thread https://honda-tech.com/zerothread?id=235464 ). Also helms says nothing about a 90% 10% mixture. (At least not where I read). You bled your engine too right? There is no "bleeder" like on the older tegs, however on cars you need to let the fan come on a couple of times, check the level, THEN replace the cap. As long as you did these things you should be fine...

 

In terms of bleeding, on the final fill I did I let the fan come on a few times and then put some more water in.

I used a 90% water mix because of a discussion on the Type-R yahoo group. I am in Arizona so freezing isn't an issue and water wetter should protect from rust, etc.

 

50/50 mix is not only for freezing, it also shifts the boiling point of the coolant up. Water boils at ~100 degrees C. 50/50 mix boils at over 200 degrees C. 90/10 is the wrong way to go. You've just lower the boiling point of you coolant.

 

But did you know that water alone is MORE efficient at transferring heat than a 50/50 mix? There are some race applications that use water and WaterWetter alone, and that's it.

 

Just remember Thermodynamics . PV=NRT . In a street application you probably won't have the cooling capacity. You can transfer to the heat, but to what? If N, R, and T are constant, then the P and the T pushing each other up. Eventually, you will boil over. The mix ratio will shift the N, which will allow the T to come down and the P as well.

 

LOL. Now that's telling em .

What are you trying to achieve? Are you running hotter/cooler than you want to? Give use some more background on your application if you want us to understand why you would go so far outside of man specs. He's right (and this is what I was trying to touch on), 90/10 is probably not the best choice, for normal applications. What are you using to test your mixture? You should probably get a tester, and see where your freezing/boiling points are, if your not using Honda 2 cooling fluid.

 

I'm not trying to achieve anything, except maybe some sanity.

 

Ah fawk it, I am going to go flush it this weekend and just put the stock stuff back in then.

Pain in the *** dammit.

 

That would be best.
