Is anyone out there using this system?(High flow pump/rad.,)The system has no h2o and boy does it smell!Does the smell go away over time? :chevy

 

When I first bought my Vette I tried Evan's Coolant. Overheated twice and the Evan's rep could never find the problem.

Personally, I will stick with same ole old fashion coolant.

Gary .... :seeya

 

Are you using the Evan's system?????
When did you install????
What did you pay?????
Why did you use it?????
Would you recommend it?????
Please let us know.....
thanks
tony

$1100 for complete system(rad,pump,coolant). It's been in for 1mth (100 miles)No complaints, but there is a strong coolant smell. 180 deg. t-stat(on200 off 180)I was told that the smell would dissipate.I am looking for a 1-1/2 id upper rad. hose(stainless) to fit the system(1984 vette). Is there any sites you could recomend for custum hoses?Thanks for the reply.

 

I used it for a while in my Mustang.

The stuff smells ALL the time, you can never get rid of the smell. It smells so strongly that people were often warning me at the track that I have a coolant leak.

I had just as much pinging with the Evans coolant as I did with straight coolant. I didn't see any real advantage to the coolant when the system was functioning normally.

You have to make several enhancements to your cooling system to fully benefit from the coolant (increased flow, larger radiatior, larger lines). In my case, the hi-flow water pump caused a disaster. After a 6000 RPM blast on the highway, the gasket blew out on the water pump dumping $100 worth of coolant onto the highway.

That's when I threw in the towel and switched to 100% distilled water and two bottles of water wetter for lubrication and as a surfactant. Damn car runs much cooler now and the detonation problem was nearly eliminated.

Water is by far the best cooling media (glycol is only added for freeze protection, anti-corrosion and lubrication). So my recommendation is to run 100% distilled water, or a mixture of water/glycol that you are comfortable with.

BTW, I have two full bottles of NPG available for a reasonable fee if someone wants them.

 

"and as a surfactant"

I like that one! Sounds very knowlegable!

If you're running in NASCAR, no coolant is fine, because you're rebuilding the engine after the race; I personally never saw even one degree drop in my coolant temp using water wetter. It's silly not to run coolant on the street.

I'm curious tho- you say you "blew out a gasket" on your water pump; As the Evans system is under zero pressure- if you read the directions and installed the right radiator cap- I don't understand how you really had this "disaster". The latest Evans product require no modifications to your cooling system other than a zero-pressure radiator cap.

As someone who has really used the Evans system for a number of years, I can report that my experience has been great- I was able get rid of my overflow tank, and I run 87 octane with zero detonation, so I paid for the extra expense long ago. It is harmless to gaskets, and under zero pressure, will be much healthier for gaskets and hoses over time.

Evans makes a great product, which is starting to see OEM application; why some people feel the need to hyperbole on these sites is beyond me. Check the SAE archives for reports on Evans- those guys may not be the "tuner on dad's corvette", but they seem to be pretty sharp............

Of course you won't see a drop in temperature. The min temperature is regulated by your thermostat. Also I am confused. How does coolant relate to rebuilding your engine??

So if you live in Puerto Rico where the ambient temp never goes below 80F, would you still run antifreeze ???

It might be zero pressure at the radiator, but it's not zero pressure at the outlet of the pump! A centrifigul pump like a water pump will generate 40 lbs of pressure at max RPM. In my case with the overdriven pulley on the water pump I was hitting around 60 PSI! It blew out the gasket between the pump and the backing plate.

Glad it's working for you. But why do you need it in the first place? (just curious) In my case I was trying to run iron heads with 11:1 compression on pump gas (a N/A 347 that was making around 430 HP). I did get it to work, but not with Evans....

There really is no need to attack my opinions here. That's what these forums are all about, sharing ideas in a community. You may not like my opinions but I am going to share them anyway. Certainly everyone that buys the stuff should be warned that your car will smell like it has a leak ALL THE TIME (I know yours doesn't smell, even though three others in this post have experienced this). I wasn't warned and it ticked me off. Of course when I called Evans I got the old "never heard of that before routine".


They are pretty sharp. But they are pretty good salesmen too! (BTW, are you on their payroll?)
