New Honda Type II coolant question?

[millionshopper]

Have anyone used this new coolant, its already premixed and cost $13. Kinda expensive compared to the old stuff in which you get more coolant not premixed.

I am planning to flush the coolant using 1 gallon of Honda Type II, 2 gallons of distilled water and a bottle of Redline Water Wetter.

My question is its says on the Coolant bottle not to add water, but since my car never sees snow I figure more percentage of water would be good with Redline water wetter.

What do you guys use on your NSX for the track/street?

When we take our bikes to the track, we drain our regular coolant out and put water wetter in. This is in case of any accidents, the regular coolant will not be on the track and cause a slick film that may cause more accidents where the water wetter is more safe and just evaporates like water. I would think if you are just running on the street, go with the OEM coolant. It works fine...

I would stay with the reccomended 50/50 mix of coolant and water. What does no snow have to do with needing adequate cooling?

 

[nsxhk]

coolant also known as antifreeze.... is needed for colder climates and is not as good a heat conductor as plain water but still necessary.

I have been reading from the S2ki forums that the more percentage of water is better for cooling (60-80% water), water has a better heat transfer than coolant, but has lower boiling point. The Water Wetter helps cool cylinder walls and prevents hot spots (resulting in detonation).

In the S2000 heat will reduce power, due to the ECU retarding timing to prevent knock. What the S2k people have done is replacing the thermostat with lower temperature one (Mugen/Spoon thermostat)and using lower % of coolant plus adding Water Wetter.

Cooler engine temperature during summer will be good for the NSX on the track/street.

I have always understood that ethylene glycol is corrosive to aluminum if mixed at substantially below 50/50 with water. (I'll assume the Honda coolant uses glycol) Although water wetter helps lubricate the pump, I don't know if it prevents the corrosion by thin glycol. My impression was that it is designed to use with just water.

I think I would do a bit more research before proceeding since the aluminum in radiators is quite thin.

I live in Arizona where the temp's exceed 110 degrees and my nsx has never overheated. I think the cooling system must be up the the job. First a mixture of more than 50% ethylene glycol is corrosive to the cooling system, secondly more water you run the more efficient the cooling system is. I have used RMI-25 for years and it works wonderfully. You can look it up on google. It works and in the summer I used distilled water and RMI-25

I am in a similar dilema and need some advise. I was going to flush the coolant on my NSX. Just curious what combination of coolant/redline the track guys are using. I live in Tx, track the car 6-8 times/year. the car is never driven in temps below 40 degrees but is frequently driven in Temps above 95 degrees.

I was debating between:
1. Honda Coolant and bottle of redline.
2. Honda Coolant
3. Honda Coolant + 1 gallon of distilled water + red line.

what do you guys think?

btw, Redline Water wetter is on sale at Pepboys for $6.99/bottle this week

Please make sure to specify which type of coolant you are referring to. (The first post made it clear, but some of the other posts did not.) The original Honda coolant needed to be mixed with distilled water; the new coolant is pre-mixed and does NOT need to be diluted (and I would not, regardless of whether I lived in a hot climate, or a cold one).

Remember, coolant is not just to prevent the car from freezing; it is also to prevent it from boiling over.

The reason Honda went with pre-mix was to ensure the warrenty work are done with correct mixture of coolant. Some techs will dilute the coolant to save some for himself, or not put in the correct mix, due to carelessness, laziness, etc. The new type 2 are high quality and should be use as is. No additional water needed.

To run cooler is not necessarily a good thing. You want to run in the designed temeperature range. Less than that, or more than that equal to less power. If you run fine with premix coolant, there is no advantage running water and water wetter only, since it will be block by the thermostat anyway and less circulation.

No additional water needed.

It seems to me that the same techs who diluted the old coolant will continue to do so with the new coolant. Certainly incorrect mixing of the old coolant was a problem, but another problem was not using distilled water with the old coolant - I have never seen a dealership use distilled water. The hard water in many areas ( such as mine ) can leave deposits in the cooling system no matter what coolant you are using.

According to the leading servicer of NSXs in the Midwest, the reason Honda went with pre-mix was because some owners were diluting with tap water instead of the recommended distilled water, and were having problems with their cars as a result (particularly in areas with a lot of mineral content in the tap water).

 

[EIFFEL]

Yes, I forgot to mention the distilled water factor,

I recently changed the coolant in my NSX and used the Honda premixed Type 2 (part number OL999-9001). The water from my well is fairly hard; if I hadn't gotten the premixed type, I would've bought distilled water to mix it with.

I paid $8/gallon, not $13. I bought it from a Honda dealer. not an Acura dealer (if that matters).

Curiously, the label says "When used as directed in Honda vehicles, this coolant will give complete protection for 5 years or 60,000 miles." The '95 NSX service manual says to change every 2 years/24,000 miles after the first change; that's a pretty big difference between those two recommendations.

That would be right. Besides, once Honda changes the color to blue, it's going to look cooler, also.

Interesting, Tom239........what should we follow, in between interval best for our NSXs? I am thinking its better to flush than not to flush according to the service manual....anyone care to chime in, that is knowledgeable about collant changing intervals?

I'm not an expert on these matters, but I'm sticking with the 2 year interval. It's not a hard job to change the coolant.
