A warning about Evans Waterless Coolants

Pay attention to who is FUNDING the article. Ebooger has NEVER TESTED the produced. He admitted that. But what is even more appalling than not testing a product and bashing the product, is jumping on the web, and using a COMPETITORS testing, without checking on the COMPETITORS work!

I lost what little respect for ebooger I had. Then, in the last issue of the rag that ebooger writes for, someone from Evans wrote to ebooger, and rather than address Evans in a professional journalist way, he was a snarky jackass.

I have never run Evans coolant. But I'm going to this time. There is so much outright BULLSHIT about cooling out there, that I FORCED myself to do some study. Here is a bit of what I found.

Flow is EVERYTHING. It's all about FLOW. The second thing is AREA. You need as much cooling AREA as you can get. A bigger radiator is a better radiator.

The third thing is the number and size of cores. You can call any quality radiator manufacturer and they will tell you the same thing. More cores is NOT better. 2 cores of 1.5 inch diameter is better than 3 cores of 1 inch diameter. It's about FLOW. A 4 core radiator is even less efficient.

The other issue is PRESSURE. You MUST have pressure with ANY water based coolant to increase the boiling point. PRESSURE impedes FLOW, and that is bad. But, you MUST have PRESSURE with water based coolants.

After looking at all these things in more depth than I have posted here, I decided to try Evans coolant. I will post my results here, good or bad. I have done all I can do to increase flow, and decrease pressure. Evans works with almost ZERO pressure. Think about that, in and of itself! No pressure (or very little) will make the likelihood of a massive leak even less. Places less load on the head gaskets as far as sealing coolant.

I would say to anyone looking at cooling systems to spend some time and learn about fluid dynamics and heat transfer. Then make your decision.

BTW, the other thing I learned is the LIE of the thermostat! Most people think you need one to keep coolant in the radiator so it can dump heat. That is a LIE. It is a flow RESTRICTION, and we know RESTRICTION is bad. The only functions the thermostat has are to speed up cold start warm up, and keep the engine at a constant temperature so the heater functions correctly. Other than that, you don't need it.

Since I drive my crap all year round, in temps that get well below freezing and can get to zero (and yes I drive it when it's that cold) I may have to use a thermostat. Time will tell.

Do your own research, call people on the phone. Write out your questions down first, before you call and take notes. Most of every manufacturer I have dealt with would much rather you call them, rather then read comic books and unvetted web pages.
