I recently stumbled upon these new products in stores that are supposed to reduce friction in coolant and make the engine run 20° cooler because of its heat transfer ability. Some brand names were royal puprple and redline. I was wondering of anybody has tried these or if they are even good for a car.

I personally wouldn't put anything foreign into my coolant. With an exception going to the GM cooling system pellets.

I first heard of coolant additives over 40 years ago. I tried one, but in a car not comparable to an Aurora (1966 Cutlass 330 4bbl). It did nothing, good or bad.

Long as we're on the subject ... global coolants. anyone? One size fits all approach - beats the carp out of having to stock different flavors for different vehicles ...

I've added Redline's water wetter over the years and used Royal Purples purple ice coolant additive in my Aurora. It cools the internal surface to help lessen heat soak. It doesn't lower your overall op temp. I would use these way before the thought of the pellets.

From www.jag-lovers.org >> 'Jim Crider wrote'>> "Here's a response from someone who designs vehicle cooling systems for a living ...... (that would be me): Strictly looking at the heat transfer coefficient, straight water is the way to go. HOWEVER... straight water has its problems, notably a lack of certain additives that prevent cavitation of the water pump at high speeds, corrosion of the various metal bits present in all engine cooling systems, surfactants to lower the surface tension of the coolant (allowing it to "wet" the surfaces of the coolant passages better) and anti-foaming agents to keep the surfactants from making big bubbles. All these are present in antifreeze/coolant. The surfactants and anti-foaming agents are present in Redline Water Wetter. Water Wetter has limited to no benefit in a system using a commercial coolant -- it's simply adding more of something already present in sufficient quantity.

Something missing from your list of benefits over plain water ... waking up on a cold winter morning and not finding pieces of your engine block all over the garage floor.
Then I suppose that's assUmed, so forget I mentioned it. <G>
I just did the water pump on my gen one and went with the Peak Global afreeze @50/50.
