EVANSCoolant EC53001 High Performance Waterless Coolant (Pack of 2)

While a bit pricey, the performance is excellent. Longevity is nearly infinite. Seriously recommend upgrading all other cooling components so not to lose this investment on the concrete due to a leak.

I use this coolant in my 2009 Jeep Rubicon 3.8 and my 2006 Dodge SRT8 Magnum 6.1. Both engines run just fine. I have gone 3+ years in the Jeep and only had the Magnum since October of 2016 and both run perfect temperatures.Everyone in the Dodge LX community knows how 6.1 overheat. I do not run a tuner so My fans are stock. I have the original stock radiator and I have no problems overheating. I believe the hottest I see is 209 then the fans come on and I jump RIGHT BACK DOWN to 190-ish.I can drive it 150 miles to see my dad and I can use my bare hand to take the cap off of the radiator. My system is always less than 3 PSI pressure.ANYONE who says it does not work did not perform the conversion correctly. You can't have water in your system. I used Evans prep fluid also.When I did my flush prep and fill I changed out my heater core with a new one, new recovery tank, washed out my RAD and blew it out with air and let it dry out. Changed ALL my hoses and even installed a new water pump. I also did the timing chain so I would not have to tear into the front end ever again. I blew out the engine with air and even jacked up my car on its side and back to make sure all the water is out....I used the provided test strips and I had the best color I could have so I know I was running less than 3% water. I had a gallon of fluid left over so I drained just about a gallon for good measure and added the final gallon.This stuff rocks. NEVER needs replacing. If something does happen to a hose or pump all you have to do is capture fluid from the radiator drain valve and store it in 2 liter soda bottles then put the caps on. I have 10 2liter bottles that I have washed out and have the caps for. What ever happens I will drain the necessary amount of Even into the 2 liter jugs and and fill them up all the way to the cap. Tighten the cap. When I put the fluid back in I will pour it back in using a coffee filter to remove any sediment.I know guys with 800HP HEMIs that run 9's use this stuff. It is good stuff.Things to think about. If you do not use a thermostat you are allowing to much flow. Any antifreeze fluid needs to spend enough time going through the radiator so it can pass flumes so you can have the proper amount of heat exchange. Never cap off your hoses to the heater core. Buy enough hose to loop back into the water pump. Make sure your bottom hose does not collapse when you rev the engine. When this happens you will see the fluid in your recovery tank go low then rise back.Don't jack the reviews because you might have other issues. This is good stuff. Also I called them up and they stayed on the line with me for an hour so I can pick their brain about this stuff. Really nice people. Call them if you are having doubts. I did and I have no cooling issues.

I have a 51 Mercury v8 flathead and it was overheating when in idle, so after reading about Evans I tried it and , WOW ! That took care of the problem no more overheating.Thanks Evans .

I had high hopes for the EVANS Coolant EC53001 High Performance Waterless Coolant, 4 Gallon Pack, but unfortunately, it fell short of my expectations...First off, let me tell you about the cons. 🤔 The coolant was quite pricey 💸, and I didn't notice any significant difference in performance compared to traditional coolants. 😕 On top of that, the packaging was flimsy and prone to leaking. 🛑As for the pros, well, the concept of a waterless coolant is interesting and could be beneficial in certain situations. 🌿 However, in practice, it just didn't deliver the results I was hoping for. 🙅‍♂️Overall, I wouldn't recommend the EVANS Coolant EC53001 High Performance Waterless Coolant. It's just not worth the investment for me. 🤷‍♂️

I have been using this coolant for years. One of my cars has had it since 2016 I think and to this day, it is perfect. Most of my cars are 70's-80's Fiats, Toyotas and Fords and the only issue is that on 2 of the late 70's fords, the Head gasket has 3 of its rear passages blocked to raise operational temp for smog purposes. As a result of the restricted flow, the Evens has an issue keeping those 2 cool. They are fine for most of the time but traffic with AC on a hot day and they creep up from 210 (factory operational temp) to 235 and then I start to get worried. Both cars were drained and the coolant was used in a couple of my other cars. When I spoke to Evans, they mentioned that this can happen with certain cars and in fact, recommended I do not use it for one of my newer Cars (2010). I love this stuff so much that I use it in 4 of my parts cars to maintain radiator, heater core, and engine integrity. Perhaps one day a newer formula can go into my trouble makers.
