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.

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.

While you guys are right if there are overheating problems, this is not the case for my rig which operates right around 195 degrees F and I am in Texas heat.

(I have tires same as stock etc...)

It does not get any hotter when towing boat or RV.

I am pretty sure that if I did something to lower the temps by 10 degrees that the thermostat would close at that point.

My tranny on the other hand, seems to get hot. Temps climb on my tranny when towing or just when facing high winds. I intend on adding one of those PML tranny pans with extra fluid capacity first to see if that helps.

The first two things I would try if I was having minor engine heat issues (and everything was working), is syn oil and water wetter. Syn oil dropped the temps on my air cooled Harley by 20 degrees.
