EVANS Coolant EC53001 High Performance Waterless Coolant, 4 Gallon Pack

I recently used this high-performance antifreeze in my car, and I’m thoroughly impressed with its performance. It not only provides excellent cooling but also maintains the engine’s temperature efficiently, even during long drives or in hot weather. The formula is designed to handle extreme temperatures, and I’ve noticed my engine running smoother and staying cooler compared to previous coolants I’ve used.

EVANS EC53001 Coolant delivers superb cooling, prevents corrosion/boiling, easy to install. Perfect for extreme temps—durable & leak-free. 5-star product, highly recommend!

I'm running Evans in two Honda Civics with the goal of reducing intra-cooling system pressures. The Evans alternative to conventional anti-freeze won't boil unless reaches 375F, and, of course if it ever did, you'd already have experienced catastrophic failure... In normal operation, it creates no steam pressure and thus will not pass thru my 16 psi radiator caps - UNLESS the coolant level is too high in the top of the radiator tank. While it doesn't create steam pressure, it does create hydraulic pressure, which is to say that the liquid will expand by (they tell me) about 7% when it heats up to say 200F. If it got filled up to the top of the radiator neck, the expanding fluid will push through the pressure cap and go into the overflow reservoir - from which it will NOT get sucked back by the differential in pressures that moves regular coolant back and forth. If you did fill up the radiator tank, the Evans will overflow until it finds its own level inside of the radiator top tank. In the case of my vehicles, one found its level approximately 0.5" below the inner flange of the neck; the other leveled out at about 0.75" below... (Normally, I run coolant right up to the reservoir overflow tube, so this Evans characteristic was initially puzzling and quite different.)For my stock performance vehicles - which never heat up unless there has been a systems failure - the merits are as follows... First, I'm hoping that the lack of steam pressure build-up will mean that the cheapo plastic radiator tanks that Honda uses will no longer explode at the seams. Ditto the coolant hoses. (Whether multiple previous failures have been due to internal pressure, or expansion-contraction fatigue is uncertain, but I'm confident that the risk of failure using Evans is substantially lower.Additionally, I like that: the coolant is non-toxic to pets and it supposedly will never age out and allow internal corrosion.A bonus on Civics like mine is that those systems only have a cooling system capacity of 1.1 gallons, so the additional cost of running Evans is insignificant, especially when compared to the price of blown head gaskets that can result from cooling system failure. The merits for motorcycles should be similarly appealing.On my classic truck powered by a SBC, the merits would be the same but would also include an ability to continue conducting heat out of the motor even if the system spirals up into the anxiety inducing 240-260F range where coolant cavitation can cause internal hot spots that can result in engine failure. That SBC system uses in excess of 5 gallons of coolant, so I'm waiting for the next coolant change cycle before making the switch, but nevertheless, even at 5 x $45 (plus the prep fluid costs), the cost is modest when compared to the costs of catastrophic engine failure that is more likely to occur when using conventional coolant...On the conversions that I've done, after the preliminary coolant drain, I opened the heater core valves and removed the engine thermostats and used a small shop vac to blow coolant out of the systems. I probably ran the shop vac for 30 minutes, but might have gotten by with less time. Regardless, my subsequent coolant "refractometer" tests showed that I had successfully reduced the water content of the systems below 1% water, which is well below their recommended maximum level of < = 3% water.

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.

prevents overheating and corrosion for peak engine performance!

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.
