Your not comparing apples to apples. Race motors are broke down after each race or so not to mention built completely different.
1. They don't run T-stats.
2. They run top of the line aluminum radiators.
3. Full technical building including arodinamics include high cooling.
4. High capasity pumps and engine cavities.
5. Miced out ports and top notch oil coolers.
6. Different cranks, pistons, fuel, engines, The WHOLE THING!
7. Environment.
8. Thru 1000. I'm stopping here.
I give it to ya, but consitering the differences and intent, not to mention how their use and built including materials this is a VERY bad comparison.....IMHO
You can't just spend 3 minutes on a video and become a coolant expert. A full understanding in technical building must be understood.
The biggest thing here is the water wetter could make sense for a vehical that has no T-stat. There is no way a cool down could happen by 30 degrees with a T-stat in place regulating it. I do understand the point to the concept, but if this was the truth, don't you think every manufacture in the world would buy it? Na, theres more here and their just trying to sell a product. Again ....IMHO.... This is just another un-regulated additive with un-verified findings.

The last piece of good advise I can give you on the deteriating thermostat neck would be in this thread:

Look at all the posts.

Your stuck on the water wetter and missing the point. Google water only and anitfreeze you will see thousands of entries that water is better than coolant to cool. NOT better in practical use because most need the low temp anti-freezing properties as well as all need the anti-corrosion properties. From a cooling perspective only, water is better and won't hurt anything in a lot of applications (summer driver only, etc)

Smart ***....... ![Smile](https://dodgeforum.com/forum/images/smilies/smile.gif)
I understand the "Point" just don't aggree to the usage and differences......Thats all.
Anyway, hell I've pissed into radiators on the trail when I was out of water and beer. If your ever on the trail and get a hole in your radiator if you find a wooden stick and cram it into the hole it will swell from the water to hold it in long enough to get you out. Just be careful and I would keep the cap off so as not to pressureize it.
Funny how this type of bickering will bring up great memories!.....![Big Grin](https://dodgeforum.com/forum/images/smilies/biggrin.gif)
BTW<------- I sold that truck 2 months later.....LMFAO

Found this in a 2000 Service Manual Which is the same build as yours:
COOLANT

ETHYLENE-GLYCOL MIXTURES
CAUTION: Richer antifreeze mixtures cannot be
measured with normal field equipment and can
cause problems associated with 100 percent ethylene-
glycol.

The required ethylene-glycol (antifreeze) and water
mixture depends upon the climate and vehicle operating
conditions. The recommended mixture of 50/50
ethylene-glycol and water will provide protection
against freezing to -37 deg. C (-35 deg. F). The antifreeze

DIAGNOSIS AND TESTING (Continued)
higher percentage will freeze at a warmer temperature.
Also, a higher percentage of antifreeze can
cause the engine to overheat because the specific
heat of antifreeze is lower than that of water.
Use of 100 percent ethylene-glycol will cause formation
of additive deposits in the system, as the corrosion
inhibitive additives in ethylene-glycol require
the presence of water to dissolve. The deposits act as
insulation, causing temperatures to rise to as high as
149 deg. C (300) deg. F). This temperature is hot
enough to melt plastic and soften solder. The
increased temperature can result in engine detonation.
In addition, 100 percent ethylene-glycol freezes
at 22 deg. C (-8 deg. F ).

PROPYLENE-GLYCOL MIXTURES
It’s overall effective temperature range is smaller
than that of ethylene-glycol. The freeze point of 50/50
propylene-glycol and water is -32 deg. C (-26 deg. F).
5 deg. C higher than ethylene-glycol’s freeze point.
The boiling point (protection against summer boilover)
of propylene-glycol is 125 deg. C (257 deg. F )
at 96.5 kPa (14 psi), compared to 128 deg. C (263
deg. F) for ethylene-glycol. Use of propylene-glycol
can result in boil-over or freeze-up on a cooling system
designed for ethylene-glycol. Propylene glycol
also has poorer heat transfer characteristics than
ethylene glycol. This can increase cylinder head temperatures
under certain conditions.
Propylene-glycol/ethylene-glycol Mixtures can
cause the destabilization of various corrosion inhibitors,
causing damage to the various cooling system
components. Also, once ethylene-glycol and propylene-
glycol based coolants are mixed in the vehicle,
conventional methods of determining freeze point will
not be accurate. Both the refractive index and specific
gravity differ between ethylene glycol and propylene
glycol.

OPERATION
ETHYLENE-GLYCOL MIXTURES
Coolant flows through the engine block absorbing
the heat from the engine, then flows to the radiator
where the cooling fins in the radiator transfers the
heat from the coolant to the atmosphere. During cold
weather the ethylene-glycol coolant prevents water
present in the cooling system from freezing within
temperatures indicated by mixture ratio of coolant to
water.

COOLANT SELECTION AND ADDITIVES
The presence of aluminum components in the cooling
system requires strict corrosion protection. Maintain
coolant at specified level with a mixture of
ethylene-glycol based antifreeze and water. Daimler-
Chrysler Corporation recommends Mopar Antifreeze
or equivalent. If coolant becomes contaminated or
looses color, drain and flush cooling system and fill
with correctly mixed solution.
