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.

As Paragon said - not really.

The thermostat will open roughly at a pre-set temp, but once it's open, it stays open. And once it's open, if the heat continues to go up, the thermostats have nothing to do with it.

So - if the thermostat is set for 180 degrees, they will open and stay open, even if the coolant is boiling out and it's at 280 degrees.

Also - Messing with the thermostats is not something that is recommended in today's strange emission controlled vehicles.

The vehicle has to get up to the optimium operating temp in as fast as possible to reduce greenhouse gases. The thermostats are designed to help with that.

The issue really at hand is how well the vehicle cooling system transfers heat away from the coolant to the open air. I have some doubts about that in an arid desert environment combined with the H3 design.

tstats are notoriously the restriction in the coolant flow in the cycle. All vehicles taken as a whole, needs them to do exactly what they do. Get the engine temps to a certain operating temp as quickly as possible then fuhgetabowdit.

But, in situations, like yours, where every little thing might matter, maybe removing the most restrictive part of the system would improve cooling. It's just like removing a pinch from a water hose. Of course, that's sort of a band aid fix.

There has to be a bigger reason.

i don't know if this is true or not but a NAPA and Goodyear salesmen told me not to use (Purple Ice) a similar product because they said that the H2 needs to run hotter for the engine to work properly the way the manufacture intended. Since the two guys told me the same thing i just took their word for it.
