Royal purple water wetter stuff

[1jeep4me]

Any of you guys use it? does it work for you

[shimniok]

No but I had good results with the BG44 equivalent. Seemed to drop 10-20° off the normal operating temp in ultra hot situations.

When I replaced my radiator in '05 I did straight distilled water + water wetter, engine ran ~10* cooler.
When my heater hose blew a while back, and the system emptied out I just refilled with standard coolant mix.

It now runs about 10* warmer.

The stuff works, don't care what anybody else says.

[Tigger4X]

I haven't used anything but distilled water and the BG44 stuff works!

[PlasticBoob]

I have seen it used in a J-10 with a 360 and it does work as advertised.

[whowey]

I haven't used the RP version. But I have used the Red Line and the new Amsoil version. Both work as advertised.

I've been running the Red Line/distilled water since '05 when I did the AL radiator install.
It pretty much stays 185-195 all the time.

Like Tad says, and he is in the Tucson area, hotter-n-a-two-dollar-pistol out there.

I have been using distilled water and Red Line Water Wetter for years now, with Preston Radiator Lubricant, my gage is always pegged to the left, on 102-Degree days, I move one needle width to the right, but I have the Oh-My-God radiator, FlowKooler water pump, the 20-inch 7-blade fan and two electric fans to boot.

Lived north of Tucson in Oracle for about a year, over in the back side of Mt. Lemon, and dialed her in pretty well.

Just flush is all out for the winter if you get freezing temps and use the anti-freeze then,

[tazjeeper]

I can not find a place that has any idea what i am talking about when I ask for it.
I did use some other stuff in the j10 and it worked great. 10 to 15 cooler. i realy notice it on hot, hot days or when I am towing a jeep home.

[1jeep4me]

Seems to work for me now. Seems like a sound 14 dollar purchase

[sungoesdown]

Just don't use it as a band-aid

[1jeep4me]

My rig has always had a great cooling system. That's why I wonder why so many others don't. This has been a pure added bonus.

[SnowShoe]

Motor Cycle shops often times carry wetter water...

[John Huebner]

I used it in my old radiator, overlooked adding it to the new AL radiator. Yes, it works...knocked 10F off my temps with the standard radiator. I think I used the Redline version...

[fasteddy]

2-3 tablespoons of Dawn dishwashing detergent works just as well...

Be sure that you use only one of these additive at a time and follow the manufacturer recommendations. The Purple Ice (Royal Purple) is compatible with OEM and common replacement anti-freezes, but there may be incompatibilities with other 'water wetter' type additives.

Also, even though straight water is a better coolant than a water/anti-freeze mix, anti-freeze also offers anti-corrosion and anti-deposit additives, and usually some basic lubrication for the water pump and seals. As little as a 20% anti-freeze to water mix should give freeze protection down to about 5 deg. F and the other benefits listed, while still giving better heat transfer than the usual 50/50 mix.

Youre right about the anti-corrosion and lubrication part but a good 50/50 or 70/30 water/glycol mix cools better than water as the glycol helps transfer heat better than just straight water

I see the surfectant is the key here.

That's not right. The thermal conductivity of straight liquid water is much higher than that of ethylene glycol. At 32 deg F, the conductivity of water is over 2x that of ethylene glycol. At 100 deg F, almost 2.5x. At 212 deg F, ~2.6x. However, if the water is allowed to go to a gaseous state, its thermal conductivity drops by a factor of ~30, over that range. Antifreeze is also "anti-boil", so mixing some in will help keep water from changing phase to steam and would, in this case, have a better overall heat transfer ability. Assuming the operating conditions would not cause straight water to boil, the higher the anti-freeze mix ratio, the lower the cooling ability of the system (everything else the same/equal). The primary purpose of anti-freeze is in the name. Vehicles are often operated in areas that have freezing temperatures, and this is the major downfall of straight water as a coolant. Were this not the case, straight ethylene glycol should be used as the coolant.

In a good pressurized cooling system that keeps the water in liquid phase, straight water is a better coolant. A 7lb system should raise the boiling point of water to ~230 deg F. A 10 lb system will raise the bp to ~240 deg F. Of course you would then miss out on the antifreeze protection, and others discussed above. And also, straight water (especially distilled) can facilitate galvanic corrosion that can cause damage to raw aluminum. Think pinholes in an aluminum radiator. The anti-freeze helps protect against that, too.

I believe so. A surfactant helps break the surface tension of the fluid and allow better contact between the metal surfaces and the coolant. Even in what appears to be total contact to the naked eye, interstitial gaps due to surface roughness and liquid surface tension allow non-contact areas filled with air. Air is a horrible coolant for a water-cooled system.

Detergent also a surfactant, and should ease liquid surface tension. I don't know if there is anything else in it that could be detrimental to the cooling system, though. I guess it could make foam.
