Water Wetter

[Alex13188]

Just curious if anyone has used water wetter in their h2 to bring the temps down. I have used it in other cars with great results and was just curious if it is safe to use in my h2. My temps are running a little higher then normal and i was hoping this would help.

I have only used it in my trackbike. I wouldn't suggest replacing the antifreeze with it, but maybe adding it to the antifreeze.

How much of a difference does it make Alex?

[Alex13188]

I dont know how much difference it would make in an h2 but in the past i have seen it lower temps by as much as 15 degrees.

first, check with someone. For some reason I have it stuck in my head that you can't add water to dexcool or whatever the hell is in our systems.

maybe it's in the manual

Its not acctually water its a coolant additive, the company says you can add it to anything but i figured i would check here first.

I realize that, but whatever is in there now, supposedly doesn't like water and if something doesn't like water, there's a good chance it won't like something benign to water.

But, I bet you can google the stuff and find out if it is compatible.

did a quick search and it has it's naysayers but I read nothing that said it couldn't be mixed.

Said to just pour it into the reservoir

I think Gm lost a lawsuit on the dexcool. But yes should check before it goes black and stops working

Contact Redline oil company as they are the ones who make it.

hey i have read the website im gonna go ahead and try it and i will post the results.

You can add water to dex-cool, so long as you keep a 50/50 mixture. Same as any type of anti-freeze, you can purchase the straight dex-cool, then mix with water for a 50/50 mixture. However, they do sell gallons of pre-mixed dex-cool/water.
I tried this stuff in my Vette, and maybe noticed a five degree temp decrease, but nothing I could every verify. Didn't do any controlled tests, just calculated a five degree drop due to normal driving habits and temps.

You will only see a very marginal difference in using a 50/50 DexCool/Water combination and Water Wetter.

In Arizona, I now use a 30/70 DexCool/Water mixture on my wife's H3 with Water Wetter (since I've had the temp issues with it), and I have seen a rough 10 degree difference. This is due to the fact that Water is a far better conductor of heat than coolant.

Of course, I also rarely see anything hit 0 degrees F here in Arizona either, so running a 30/70 mixture works fine.

In my H1, I use Shell Rotella ELC, which is a diesel based DexCool variant. I've seen an actual drop in operating temps doing a 30/70 water/DexCool mixture with the diesel specific Water Wetter.

In the peak of summertime, I would consistently get temps up to 230 degrees F with a 50/50 mix and running 65+MPH. Going to a 30/70 mix with Water Wetter gave me a drop down to 215 at most (normal operating temp is generally 195 to 200 degrees under normal outside temps) running at a consistent speed of 65+MPH.

So it does and will work with Dexcool. You just have to run a different water dilution mix though for optimum results.

Hmmph..... I though about your cooling problem and had an idea.... some time in the past week or so, but I forgot what it was. It had to do with one of my tractors, I think and I also thought about PhilD's situation.

Did you get your H3 straightened out?

So far, the coolant mix ratio seems to have been the best solution so far. Of course, I have it marked on the expansion tank with a sticker showing the solution ratio as well.

My wife hasn't seen any issues with the new mixture either, and she says it's more comforting for her to see the temp gauge in a normal position.

Of course, going to anything below zero degrees is out of the question, but it's not likely I'll have that problem anyways considering where we live.

Your thermostat is ultimately going to determine the temps.

well, that's not true. the t-stat just opens at a certain temperature to flow the coolant. Cooling efficiency, air temp, humidity, engine efficiency, vehicle load, air flow, etc. will all ultimately determine the temps.

In Phoenix, he could effectively get away with no tstat in his system if it was running hot like he had mentioned before.

Dude-Seriously...Understand what something does before you speak about it. The T-Stat controls the operating temperature up to its opening specifications. After that, the most a stat can do is limit flow of water. To a fault if its of poor design. On some systems the stat will slow water down to aid in the transfer of heat from the engine. Pass water to quick and the heat never leaves the metal to the water.
