I used to use it years ago...it's just so hot this summer, I wondered if it might not be a good idea. Also, if you do, how much do you add?
Thanks...

Yep, diesel version.

allenjdmb

I"m ignorant here...
There's a diesel version? And you use it in your AMG?

Bahnstormer

I learned about the diesel version here on these forums. It doesn't have the anticorrosive agents which you don't need if you're mixing with antifreeze. Those particular ingredients in the regular Water Wetter don't combine well with the coolant anticorrosives. Do a Google search and you can find out more about it. I use the diesel Water Wetter in my E500, a V8 but unfortunately not an AMG.

It has been fairly hot in our region and I have not noticed any deviation in operating temperatures.
Are you guys seeing higher temps on the displays in the clusters or is this more of a preventative measure?

allenjdmb

So hot this summer. So many failures on so many things!

iconoclast

What has failed on your vehicle from the heat?

allenjdmb

I just meant that the road is littered with debris from tire failures, cars with their hoods up, parked on the side of the road. Just no sense in being that guy....

Is Water Wetter going to deter any of that? Not sure what one has to do with the other.
I know guys who use this stuff in motorcycles or heavily modified vehicles on the track but for daily use I don't think it going to improve anything.

allenjdmb

Of course it's not. I have no delusions about it.
I'm just the kind of guy who wants to take every advantage. If it runs the tiniest bit cooler, then it's worth a little bit of money to me. If not to you, no problem. Just a little bit of OCD attention to detail.

Water Wetter helps eliminate hot spots in the internal engine components and allows for better heat transfer. It's not just about the overall temperature of the coolant mixture.

I suffer from the same automotive affliction however I have yet to buy into the water wetter hype.

I dont know if anything has changed or if new videos were uploaded but I saw several youtube videos years ago that water wetter made a negligible difference in operating temps for most vehicles. If something has changed I'll be one of the first to buy it but if the system is working well and you are within range of what the engineers intended is there a reason to add? I am not debating but simply inquiring.

Due to thermostats, operating temperatures will not be affected with an additive such as water wetter. Thermostat will open later and more slowly if water wetter did indeed lower operating temps.
However, the ability of the product to eliminate hotspots alone is worth the price of admission. Recovery time for the car after hot laps should be reduced as well.

Bahnstormer

​​This.

iconoclast

Gotcha. Thanks for the clarification.
Looks like I'll be adding a bottle this weekend.

iconoclast

Over the weekend I added a full bottle of Diesel Water Wetter. Typically the vehicle operates around 195-211F on my morning commute. The past couple of days the temps did not go above 197-199.
I did not purchase this for the possibility of lower operating temps but more so for the elimination of bubbles and hot spots as stated above but I have noticed a minor decrease in the overall operating temperature. I will wait for a longer period of time and some more miles to be put on before making further comments but considering the price and the potential... it's worth giving it a shot.

To be honest despite my knowledge about what water wetter can do, I completely forgot to put any in this car after the last radiator service at the dealership couple years ago.
This thread reminded me and I picked up a couple of bottles (diesel version). Added them (intercooler and main radiator) on Sunday and I immediately noticed the car will stay at 197-199 unlike just a couple of weeks ago where it was consistently at 199-212 in traffic especially.
It has only been 2 days but another change I have noticed is the fans do not run after I park. In this heat, a couple weeks ago, it will run for 30 to 60 seconds after I turn the engine off and park. Now nothing. Definitely the most dramatic changes I can remember on any vehicle running with water wetter.

So while I did not plan to see any reduction in overall running temperatures with this additive, I will say it has more than exceeded my expectations.

Bahnstormer

From my experience there's no downside to using Water Wetter, and any decrease in engine temps, be it coolant or internal components is a good thing.

kponti

Never seen 192 oil and 195 coolant temps after driving for an hour in stop and go and idling in 113 degree ambient temps till i added the water wetter. Now I'm not saying the oil temps have anything to do with the water wetter but all this started after I added it, not like before where at idle I would have 200 to 215 on both.

Anyone knows the difference between "Water Wetter" & "Purple Ice"..?

-;ZAYED;-

Sat in essentially stand-still traffic all the way to the Hamptons and the gauge never broke 199F.
Once traffic broke it was under 195 the entire time at 70mph+.

A group of us were together today and I was speaking with one of my father's friends. He is a big "American Muscle" car kind of guy and he told me that their preference is all "Water Wetter" w/ Distilled Water instead of running coolant. He didn't recommend or know anything about "Modern Motors" but said that the combo they have been using for ages has worked and produced very good results.

I haven't had any issues or concerns with the blend but I am curious if anyone here has gone as far as that route and if so any improvements.
I feel as if at this point few degrees here or there is a negligible improvement considering how hot the motor runs in general but curious what others have found.

Bahnstormer

From what I've read, most guys using straight distilled water and Water Wetter are running track cars, not daily drivers. I'll stick with the water/coolant mixture, along with a bottle of Water Wetter.
