Who's running dawn?

[Bigsyke]

Now that summer is here, who is running dawn in their coolant? I know alot of people use water wetter, but dawn is the same thing, when used with at least a 70/30 water/coolant mix.

2 small drops max

[!Zar!]

Search.

Shit's been covered before.

[Bigsyke]

I tried, I only found threads on water wetter, not threads about who is using a drop of hand soap. I was only curious.

[OBEEWON]

Have you noticed a difference?

[!Zar!]

That's wierd. I remember a handfull of threads about people talking about putting soap into their radiators.

There are even threads about people putting eggs in their radiators.

Have you noticed a difference?

I havent, only because it was on a honda. But alot of the guys on theoldone (endyn) swear by it, and have been doing it for years.

Does the same thing as waterwetter, by increasing the surface- without the silicates(sp?)

That's wierd. I remember a handfull of threads about people talking about putting soap into their radiators.

I only found one topic which stated soap and eggs. However nobody seemed to understand the soap part.

[!Zar!]

Just don't do it.

Make your life easier.

I've actually never heard of this. Is there an ingredient specific to Dawn or is it liquid detergent in general?

[Bigsyke]

You suggest water wetter instead for the silvia?

Taken from spraytec.com

The basic rule on Wettable Powders is that a Surfactant must be used every time, even if it is only a laundry or dish washing , soap or detergent. (By the way, detergents such as Tide, Dawn, Ivory, Lux, etc. make excellent surfactants, especially in hot weather).

We use a few drops of Dawn in our demo derby cars here. They stay cool for about ten extra mins. with it. These motors are just basic sbc 350s with cams and open headers. We run a rad. with no fan, not allowed. I don't know if I would do it in a daily driver though, unless it was all new parts including the heater core. The water that comes out is pretty nasty after only about 30mins.

Its an ingredient in the soap (which dawn has) that increases surface tension. This increases cooling efficiency only, not boiling the point. Effectively you can get a better reading of the temp's on the car because more liquid is being contacted on the coolant sensor. I know water wetter has silicates, and has been known to leave an oily residue. I would think a drop of dawn wouldnt contain any harmful deposits WW would have.

I have searched around alot of sites, I cant find any conclusive info on any topics (water wetter or Dawn). The best reading i have found was on honda-tech. A few of those guys have ran a drop of dawn soap in their cars for ~25 years and swear by it. Supposidly Endyn suggests this too, but couldnt find anything on www.theoldone.com (http://www.theoldone.com)


I'd be curious to bust a WW myth by seeing if its really just falsifying the temp readings by insulating the temp sensor. Some PC water cooling guys have reported a oily residue left in the lines. Wouldnt a more efficient cooling system report higher temps water temps on the analog reading (removing more heat from the engine block per ounce of water)? Sorry just thinking with the fingas

We really should. Ive been doing alot of reading. I know cascacade will corode the F out of alumunium. (used it to clean the block once, and had to wirewheel the calcium deposits off)

I dont think a small amount of dawn will hurt when its pressurized (our 0.8bar caps should vent any bubbles). As long as the soapy water doesnt dry in the radiator its 100% safe. Even dried antifreeze will leave deposits.

I just wouldnt run a drop or 2 of dawn soap without at least a 30-40% coolant mix.

Here are some quotes I have found on H-T;

I have been using a couple of small drops of REGULAR Dawn for 25 years... So put a couple of drops in the radiator, then use the rest on your dishes! http://images.honda-tech.com/set1/smile/emwink.gif
However, I don't think it matters between regular and concentrated.... we're just playing with and modifying the solution's surface tension or it's ability to wet the block and radiator... Oh, now I get it, water wetter! http://images.honda-tech.com/set1/smile/emwink.gif
BTW here is what is in Redline Water Wetter:
DiIsoPropyl Alcohol Ether 1-4.9% Bigmoose thinks this is dissolving agent and dispersant
TriIsopropyl Alcohol Diether 1-4.9% Bigmoose thinks this is dissolving agent and dispersant
Sodium Molybdate 1-4.9% Bigmoose thinks this is a corrosion inhibitor for steel
Tolyltriazole 1-3% Bigmoose thinks this is a corrosion inhibitor for brass and bronze
PolySiloxane Polymer Bigmoose thinks this is a ionic surfactant Now you know...perhaps... you chemists backstop me here.

ts a solution made by redline that effectively decreases the engine coolant temperatures to achieve a cooler running engine.

do a search you will find some very good information on this (especially search the archives). Water wetter is basically the same thing as dish soap. However, it does have chemicals in the solution to keep the system clean and free of corrosives. i put in two drops of palmolive and it dropped my cruising ECT's by 10*



Cooling systems are an often overlooked area of any car. People often think that as long as the gauge isn't above normal then that's all the attention needed. The thing is, that the cooler you can allow your engine to operate, the lower underhood temperatures will be. This will also reduce intake temperatures due to a reduction in radiating heat from the head to the intake manifold. So how about something quick and simple that can reduce ENGINE temperatures as well as oil temperatures as much as 20 degrees? Get some hand soap or dish soap (I use the brand Soft Soap...thanks T.O.O.) and add a few drops of it to the radiator. This means two or three little drops, thats all thats needed. Why does this work you ask? Well the addition of such an additive breaks the surface tension of the coolant itself allowing it to more effectively "cling" to internal surfaces, which will in turn cool the engine more effectively. What will be the result is overall cooler engine and oil temperatures. This has a great effect on reducing thermal breakdown of the viscosity of the oil, which may allow more "leakage" into the combustion chamber. This leakage into the chamber will result in degradation of the knock resistance of the fuel itself. Also, more effective cylinder sleeve cooling will allow better heat transfer through the rings, valve seats, and plug threads which will increase the detonation threshold. Now as a sidenote, your coolant temperature sensor doesn't actually show you ENGINE temperature, it shows you coolant temperature. The boundary layer that is present not only keeps coolant from acting as it should internally in the motor, but keeps it from completely acting upon the thermally dependent temperature sensor. What this means is basically, after adding the soap, your gauge may actually read a tad higher. Don't be alarmed because this is telling you that more of the coolant is actually acting on the temperature sensor, remember it causes the coolant to "cling". This will allow the coolant to give the gauge a more accurate reading, by more completely contacting the sensors surface! All that results is a better ability to monitor the engines true condition, as well as prolonged engine life. And you thought Dawn was just for taking grease outa your way.

i coat my hand in soap and run out to dip each one of my fingers in 5 of my friends radiators to get everybodies coolant system up to par. Scalding my fingers with hot coolant is painful but saving 3 bucks is fantastic!

ive used soap drops for years . it works great. dont have any corrosion issues so far.....

I get my 2,3 drops of liquid hand soap for less than a cent or free if I take some from a public restroom.
... Yes, I'm a cheap bastard http://images.honda-tech.com/set1/smile/emsmilep.gif ... and don't see any sense in using water wetter.

I've used 2 or 3 small, note the small, drops of Dawn dish soap for decades FWIW.

I use the Dawn dish soap (because that's what my wife uses http://images.honda-tech.com/set1/smile/emsmilep.gif ) with a 50/50 mix of Fleet Charge antifreeze and distilled water. If you search on my name and antifreeze I think you can still find my diatribes on antifreeze and my disrespect for a particular organic acid stabilized antifreeze in particular. I continue to like Fleet Charge a LOT.

I had a conversation with a guy about this the other day.
I guess it helps keep the water on the parts of the motor instead of boiling and having air pockets or something. I understand what he meant, I just can't re state it..

That's about right, it lowers the surface tension so that air bubbles can't stay together.

Yeah i read that one. its like a quick fix about cracked radiator.

well i guess if it works for that guy i dont see why it doesnt work. but i totally second that vote for myth busters getting on this topic lolz. make sure they use a 240.

[drift freaq]

hahhahaha and his title makes you think he is asking about some native American.

[honeybadger]

If you need the extra cooling distilled water + upgraded radiator would do ...

[SoSideways]

Saving $3 was the reason for someone to do this?

Come on, get real... shouldn't be modding cars if you're nickel and diming 3 fucking dollars.

I think you missed the point. Im not saying its a replacement for WW. I live in an area where I need to keep a 50/50 mix. That was one guy in the quotes I provided. Its not about the 3 dollars- I'd pay $30 for a bottle of water wetter if it didnt contain silicates and didnt leave a waxy residue like some of these PC cooling guys claim, and if a drop of soap didnt increase the surface tension without any harmfull sideeffects.

[SoSideways]

Precisely my point. I was laughing at that 1 guy's reason to do this, which was saving $3.

I've run water wetter in my car since... a long time ago, and awhile back I went to pretty much a 100% water + 1 bottle of water wetter solution, and it's been fine. I am in FL though.

Recently, I've added some coolant in and the water seem to have went out my make shift coolant overflow tank (a Gatorade bottle), so I guess I've basically lost all the water wetter and am running like a 10/90 coolant/water mix now, and I've seen my temp go much higher than before.

I didn't really notice any type of waxy surface where the water + water wetter had been though.

In all seriousness, what's wrong with running water wetter? Are you looking TOO far into this issue? I mean, lots of people have run water wetter without any issues, so why try to reinvent the wheel?

Im not, I just find it interesting on claims of a drop of dawn to increase surface tension, thus increasing cooling efficiency of your car.

Im all about efficiency

--------------------------------------------

Tomorrow im going to flush the coolant, and see what comes out. I should probably invest in a temp sensor on the upper hose to datalog.

So what do I do again lolz?
Naw for real couple of drops of dawn in my radiator and ill be chill?I run SR with a koyo and dual 12inch haydens.Any type of dawn in perticular?

You're giving premies a bad name with that post just now :fawk2:

Regular dawn, the blue bottle - none of that antibactieral crap (dont know whats in there) 1 drop, or 2 if you want (MAX)

or just run water wetter.

geeezzzzzz!:ghey:

[Bigsyke]

Everyone just relax, this is a thread of science!

[!Zar!]

Oh, I'm sick of all of this.

If you shit is running hot, then it's a problem that needs to be fixed.

Stop trying to bandaid the problem with fucking cheapy shitty ghetto mods.

The car runs fine STOCK with the STOCK fan shroud and fan.

So wtf is the problem?

For you people that have a fail koyo, why do you need to run cooler?

Shit already runs cool.

WTF is wrong with everybody!?

You know that it's possible to have a car that runs too cool.

Then it stats having ill effects to your car's engine life and performance.

Gah!

[Bigsyke]

^^true, but a good working thermostat should control the coolant temps reguardless of radiator cooling setup. The engine temps and coolant temps dont always go hand in hand, so whats wrong with chatting about increasing efficiency? The stock exhaust is just fine but people modify it.

And being too cool only happens when the oil cant get to the proper temps to burn off any impurities, such as blow by- or non burnt fuel excaping past the rings with a PCV valve thats not up to par. Im running altima fans that turn on when the OEM A/C fan kicks in @ 202*f i believe? So I wont have any issues with being too cool.

Its only a discussion.........

[!Zar!]

But that logic is about the same as someone who takes asprin just because it will help them from getting sick if a cold comes along.
