Here is a small cooling story to relate some good information,,,,

[MonzaRacer]

A long time customer brought his new purchase to me to science out the cooling system. Crappy small Derale knock off fans let it get hot.
He was told it was a 355 turns out its a 060 80 400sbc.
So he decided to pick up a big aluminum radiator off ebay after I showed him what to look for. For the cash for street driven they work, not super pretty but functional.
BUT he had issues so I pull out a few of my cavalier style fans.
I have used these for years with great luck and never had any issues.
But for the most part we never got this unit to cool good enough,,,it always ran very hot,, like near 220-230 never lower.
So I pull out my nearly guaranteed cooling system fix:

www.Evanscooling.com NPG+ brought it right in line, threw away the 22 lb cap for a 2 lb, new water pump flush the block and heater core with flush, new 195 thermostat as it mad horrible power colder.
Car runs to 205 cools down to 185 then levels out.
Fans cycle and it runs a thousand percent better and no over heat.



Honestly guys this stuff is awesome,,,, 375degree boiling point with no pressure, -40 degree freeze point and it only gets slushy IF it freezes, never gets hard as it has NO water.
Oh and it is kid/pet friendlier as it propylene glycol,,, and no corrosion.
See if you have water and EG it can become almost like acid/water in a battery and with cast iron/aluminum,,,old AF tada electrolysis or your engine becomes a battery.

Yes its expensive, last cases I bought was $39.99 a gallon plus shipping and its doesnt have nasty haz/mat issues.

So guys look into it cause it works and its not super rocket science, just a good part for our hobby.


Good Luck!
