I run water with a bottle of water wetter in the Houston heat!

Guys, are all of you that are running water wetter running your car with split cooling and are you adding this to engine as well as s/c circuit?

Hammer Down

Once I split it I will, you have to make sure that you follow the directions when using with the rear reservoir. (I'm talking about Royal Purple)

I just have a split system with the bmw reservoir and trying to figure out how much to ad to both circuits or just the s/c circuit.

You may only need to add an ounce or two to your front reservoir and add the rest to your main system.

awesome. Thanks hammer. getting ready to bleed the coolant in my s/c circuit where I usually run 35% MB coolant with distilled water but I figure every little bit will help since I got a 172mm ready to go in.
Each time I think of adding more power and I see your sig I think , damn is it even worth it, why not just get some drags lol.

You guys just pouring the bottle into the coolant reservoir? I have a bottle sitting here, figure I may as well throw it in.

would I see any issues using distilled water + water wetter? I do not have a split system.

Also on the back of the bottle it suggest purified water...? Any idea why this would be preferred?

split the system 1st and then water with some water wetter.

you suggest the BMW split system? Isn't it only like 40 bucks to do the split?

black06c230

Yes just use the BMW resv and then split. Also I would replace the IC while you are at it.

Toadster

I use this stuff - $8 bottle

Hy-Per Lube Super Coolant - 16 oz.

I just did my cooling added a water wetter... I saw the royal stuff and read some bad reviews and went with water wetter instead...

Manuyc

im next to do it to with water wetter.
i had it in my bmw that was S/c

berti_00

nig you can still go get one and dump that biiiaaatch in aightttt

I think they are just using "purified" as a broader term. Distilling is a form of purification as is de-ionized, or reverse osmosis. There should be no issue with distilled water.

On caveat, never run pure water all by itself in a radiator. Some people have because pure water has the greatest capacity to remove heat. The problem is, pure water is actually aggressive in the sense that it loves to dissolve stuff like the material in your cooling system. They don't call water the universal solvent for nothing.

It doesn't take much, like a bit of coolant to buffer pure water and stop in from being aggressive.

Water wetter will break the surface tension of the water and allow it to make better contact with the surfaces in the cooling system thus improving heat transfer.

Apologies for the science lesson.

No I appreciate the detail. Last question, is it okay if I run only water + water wetter in my coolant system? Also someone said add a drop of dish soap, is this in addition to an additive or instead of an additive? Thank you

^ I would look on the label of any product to make sure, but I believe all of the water wetter products like royal purple have corrosion inhibitors in them also. The product toadster listed shows "corrosion protection" on the front of the label.

so it would be okay to run purified water + water wetter only. Of course you have no freeze protection with that set up which is no big deal depending upon where you live.

The old dish soap trick can work, but I would not try it. The stuff in water wetter that breaks the surface tension of the water is surfactant. It is an ingredient in dish soap. Surfactant packages often have foaming agents which are great for cleaning dishes, but not so good for maximizing water contact with the surface of a cooling system. I suspect there is an optimum amount of dish soap to put into a cooling system to break surface tension without foaming, but I don't know what it is. The water wetter products do.

A final note. As I understand it, surfactants are all pretty much the same from product to product. I suspect a product like toadster used is every bit as effective as Royal Purple. That said, I still run Royal Purple.

The real question is what is chad running in his split I/C? LOL!

MACEDON

So can i just dump a whole bottle of the royal purple stuff in the coolant tank with coolant already in my system?

Or do I have to carefully measure out ratios... I imagined that with coolant even if you have a bit extra of this stuff it shouldn't hurt

please advise

Just chuck in one bottle. It works with old antifreeze and new antifreeze. Some run it with distilled water. Better cooling, but I am not sold on it providing enough corrosion protection and lubrication for the water pump personally.

trabots

This is what I have been advised. 100% water has the best heat transfer. In a split tank/ HE system, distilled water is better as mineral deposits will eventually reduce heat transfer. Only add enough antifreeze as necessary for below freezing ambient temps. I now have a KC which needs some antifreeze as the water leaving the KC is often below freezing so says Mr Kincaid. The addition of a surfactant is interesting and I will be looking into that.
