Got this installation info sheet with My thermostat .

Thoughts on water / coolant ratio .   I've allways done  premix of late .

Redline Water Wetter  ... any opinions on this ?

Tune should accommodate revised fan setting  for 170 t-stat ?




this  t-stat is for both the 3.5 ecoboost and 4.6 DOHC

Most premix is 50/50 and the highest recommended coolant concentration, even for arctic conditions, is 60/40.  There is usually no need to adjust the premix ratio, unless you are running in VERY hot conditions.  Water does flow more easily than coolant, so it tends to heat up/cool down faster.  In that case, you would lower the coolant conentration to as low as 20/80, and Water Wetter may be of use.  This is a (brief) link for boats, but principles remain the same http://marinemechanic.com/site/page39.html

As SHOdded has stated water is a better coolant. It cools off faster, where is some cars straight antifreeze can cause cars to over heat. Proper mixture is key, I believe I have seen a chart for mixing based on climate. Redline water wetter I do use and does help. To get full benefit of lower tstat you need the tune adjust to have cooling fans to come on earlier. I have a 2 tunes one with lowered fans setting for summer and one for the winter with normal fan settings.

Does it matter if straight tap water is used or is it preferred to use distilled water?

Use distilled - it is cheap and you don't really know what is in your tap water.

Distilled always never tap water.

The mineral content of tap, well, city water, etc. can deposit and clog passages.

In my Mazdaspeed6, I ran 100 percent distilled water and just a bottle of Water Wetter in the cooling system. Let's just say, I had to be pretty dang careful around winter months.
In order to do this, I had to flush the system pretty throughly, so there there was little to no coolant left behind.

My manual says to stay between 40/60 and 60/40. 

Crash712us  and  IHeartGroceriesis are only ones so far that say they use Redline Water Wetter . I guess I need to read up more on it cause it seems to be a good thing .

Depends on where you live, we have great luck with it here in AZ because we don't freeze, don't know about the rest of the country though.

Used to race my GSXR 600 in the Supersport class, and had good results using Water Wetter with a straight deionized water mix, as we weren't allowed to use any anti-freeze in the cooling systems for the obvious reason.  Running it in my Flex with the lower t-stat, but keep my water to anti-freeze ratio closer to 50/50 as it's just too damn cold here.  There are all sorts of debates regarding using deionized water versus distilled water, but as long as you don't use hard water is the main thing.

I really don't see the point in water wetter in a vehicle that is not having cooling issues.While driving any advantage (usually very slight) would only result in the thermostat closing off to maintain the temp. or while in traffic would make the fans run a little less.It's not going to affect the performance any.

For the daily driver, I would agree with you, but for those running aggressive tunes or seeing track time, the benefit would be in the consistent lower temps versus not running it.

So would the real question be one of viscosity of coolant vs Water Wetter, or is the Water Wetter better (significantly) than coolant in its' heat dissipation properties, or both?

This Stuff Works I was skeptical at first about this product - but I noticed Fire departments using a surfactant like this in the Pumper to help them extinguish fires faster. The surfactant breaks the surface tension of the water and allows it to surround and engulf the burning object better.... it makes water "wetter"

So, I figured the principal was sound - and I tried it out in our run-hot prone Porsche® 928. It WORKS. I have used it now in the race car for 2 seasons with no over-heating, and in my street-driven Porsche® 928 also.

Have a look at the photo attached - that's the 928 at idle with the AC on, on a HOT day. Water Wetter moved that temperature needle about 5 to 10 degrees to the left from where it used to be. Cheap insurance against over-heating, warped heads and engine repairs.

One bottle is enough for your 928 cooling system. If added direct into the radiator, you will see the results that day. If added into the coolant reservoir, allow time for the chemical to distribute itself into the system fully. Supercharged users: does a wonderful job in the air-to-water intercooler system too!
