Anybody switched their cooling system over to this stuff?

 

Hopefully not.

 

why not? Is it not a good idea?

 

Expensive and unnecessary?

 

Google no-rosion.com


Interesting, but probably with a bit of bias.


It is complex and expensive and not risk free.


Tis glycol. Ethelene , propelyne or both.


Flammable, as well.


Not for me...

There's been plenty of discussion on this site of the Evans coolant and it's 'bad science' marketing claims and more importantly the significant downgrade in cooling efficiency- the very last th,ing an owner would want on any vehicle.

The outrageous cost is the least of the problems.

 

i aint touchin this topic!

but i have used it in 3 different engines without any problems!

follow directions , and works out OK!

100% No corrosion, will not boil, until engine coolant reaches 375/400*F, by then you have other things to think about!

altho it seems to work better in hot climates, it is an oil, so gets thick in cold weather!

 

And yet you jumped right in.

 

its about time you had a retort!!!!!

 

When you need to top up your water based coolant, it is easy - you can find water in most places. Now if using water-less, you need to be carrying it, and if you have a significant leak - you are stranded!!

 

I wonder if the Merlins, Allissons and Packard V12's of WWII used pure
glycols or a H20 glycol emulsion?

The early Merlins ran 100% ethylene glycol, the Merlin X on ran 70%-30% water glycol.

Apparently the 70/30 mix made the engines a bit more reliable, and reduced oil leaks ???

 

jeez wiz ; if you have a leaky cooling system, then NO do not use an expensive coolant , fix the car 1st!

 

.

what andrew said, true.

ethylene glycol developed for Allison 1710, late 30s

propylene glycol , Evans coolant developed for SR71 Blackbird (hydaulic systems), 85000 ft its gets cold, but temps inside get super hot, skin friction starts to glow red,Titanium! not good to have anything boiling.

speed around 10,000 mph,?

 

if any interest, i used Evans for 11yrs in a turbocharged Rotary engine, maybe added a cup full of Evans.

and when i drained coolant it was a clear amber color,(like color of beer), 11 years!

seals and bearings perfect, cooling pump, no corrosion anywhere in the system, same hoses as i started with.

490whp, drained system , because sold the engine to a guy, and put same fluid back in, filtered 1st.

now things i learned , you need a good hi volume/hi pressure pump, stuff gets thick when cold (minus 40F and down).

No hi pressure cap, i run a 7 lb cap. room for coolant expansion, large resevior tank.

some run no pressure atall, open vent! maybe a catch can?

negative ; banned at all race tracks, if it leaks on to track , its a veg oil, slippery as ice,
so that means a good system.

and if you have dog/cat drinks any no problem(non poisonous)ethylene will kill them.
