Project Farm tests coolant boosters/water wetters

[johnmyster]

Why is he wear scar testing antifreeze additives? (Not important for cooling system.)

Agreed...didn't get that. Maybe because the lubricity could be somehow correlated with claims of maintaining lubrication of the water pump?

Why is he testing them for pH buffering? (My coolant does this.)

Seems relevant for coolant additives to me.

Why is he testing boiling point elevation? (My coolant does this.)

Seems relevant for coolant additives to me.

Meh, my water pumps have ball bearings that are outside of the shaft seal. Rolling wear doesn't occur under coolant immersion. By the time the bearing has coolant in it, water pump has failed. I suppose a thermostat could develop a tiny wear scar from opening and closing...

I've never had coolant, changed on appropriate intervals, to fail to control pH.

I've never had coolant to boil unless the system is overheating, failing to maintain pressure, etc.

So relevancy of the tests is only outside of normal operation of the system.

Then why do some coolants advertise "lubricates water pump" or similar?

I've never known a coolant, changed on appropriate intervals, to fail to control pH.

I'm confused. He is testing coolant additives and their potential impact on adding them to coolant (or using on their own) so yes, it's a valid question as to whether they control pH the same as straight coolant. At least that's how I'm undestanding this.

See above.

Relevancy is for using a non-standard coolant and what impact it has, if any on the normal cooling system operation.

I'd think having clean heat transfer surfaces (acid flush of radiator to rid corrosion products, which are ceramic/insulators) and good airflow across the radiator (free of leaves, pine straw, and bird feathers) are going to be more dominant than benefit of surfactants. If the radiator tubes are long/thin enough I'd have a hard time imagining the surface transfer rate from coolant to tube is the limiting factor.

My trackhead friends are always switching to straight water this time of year because of hype behind higher specific heat of water vs glycol. Granted, the frailty of E46 cooling systems may be a factor. Better to spill water than glycol on the track.

Yes, the water wetter additive is to help when you run straight water to prevent corrosion. Yes, better to spill water for sure but all of the HPDEs I've done do not have that requirement. For W2W racing, 100% have that requirement.

 

[TiGeo]

So what were the results @TiGeo? Are you going to continue using WW or no?

Yes, I have a 30% coolant blend with Redline Water Wetter in there now and have been running a mix like this for some time. It's a "why not" kind of thing....even if it helps my cooling system by 2 degrees, I'll take it for $12.

Then why do some coolants advertise "lubricates water pump" or similar?

There's a seal that "needs" lubrication, I guess. Or perhaps that's a marketing move towards people that don't know any better. People that are car nuts but have never held a water pump. On my three cars the water pump shaft bearings are not immersed in coolant.

Your basis is that he's making sure that these enhnacement additives will not impair the basic functions that coolant should provide? To restate, since the additives are diluting the coolant, let's make sure it doesn't dilute the functional aspect of the coolant?

Amsoil dealers will be along shortly to sell us some full synthetic coolant.

Which salad dressing tastes best...as determined by the wear scar tester.

Everything is a nail when you really like your hammer.

Ranch holds up the best followed by Thousand Island.

 

[TiGeo]

Has he done a video on Jergens, Dove and Vaseline?

Don't think so, at least not in this context. Reach out and ask him.

Exactly. I thought that was obvious? Amsoil I'm sure has an additive similar to this with a catchy name.

Generally if I'm looking to justify an additive, I want it to add/improve some property of the working fluid. Not just fail to degrade the functional properties of the working fluid.

Hence why he tested them...

Then what do the additives add if they only fail to degrade properties that are either irrelevant or sufficiently covered by good coolant in the first place?

In other news, LSJ has another youtoob video out.

Do you understand the purpose of "water wetter" products?

Do you understand the purpose of "water wetter" products?

Absolutely. I can remember my thermodynamics classes. Thermal boundary resistance. One would have to suspect it as the limiting factor for heat rejection in a radiator and then test specifically for that property.

Really enjoyed this one and had some reservations as many of us do but the information he provides is good to excellent. There are so few free to the public resources like this, I hope we see more. PF is a gem on YouTube.

Really interested in the results on Evans as I had looked into it several times in the past. The results in this video line up with my expectations which was encouraging and a relief. Great stuff but it only leaves me wanting more.

TBH, when I hear these videos, I get aggravated. His voice is just terrible and editing is just too fast. I do not watch his abominations anymiore.

I would agree that his voice lacks ... rich, chocolatey notes and the timing of a suave salesman.

Every sentence starts with AND...

Missed oportunity. Cavitation, micro bubbles and bubble suspension. The reason to use it is to keep micro bubbles from forming on the hottest surface in the cylinder head and to eliminate any micro bubbles because bubbles do not cool. Cavitation is also bubble forming. When heat or cavitation generated bubbles collapse it is corrosive not due to the PH but because of the energy released by the collapsing bubble. Yes that collapsing bubble energy erodes metal. Example would be pits on a boat prop from cavitation bubbles. A cool example is watching cataract eye surgery. You think the needle is jack hammering away at the cataract but if you zoom in you see that the pulsing needle never touches the cataract. What is happening is the needle pulls back so fast that it generates a cavitation micro bubble. That collapsing bubble is the shock and energy that breaks up and erodes the cataract eye lens. I like the guy in the vid but unfortunately he missed every point of why to use these “water wetter” products. Pick a flavor and buy them.

Because they just make stuff up that sounds good to the uninformed.

Project farm. Leading in nonsense.
