Evans Cooling Systems EC42001 Waterless Prep Fluid With Funnel, 128 fl. oz.

Worked great I was able to remove 100% water and old coolant.

Fast delivery of the correct amount of containers of Evans. Will work great on my 1984 Honda CR250R.

Evan's waterless coolant - solution? - egr - cavitation - corrosion of oil cooler exchanger / radiat yes, I made the plunge into evan's waterless coolant. I have been working on ways of remediation of 6.4l problems...oil bypass, coolant filter, airdog, metal screen primary oil filter, stage 2 push rods (drilled out), triple ester based motor oil, etc. my list got shorter to how to resolve egr corrosion coolant pump cavitation oil cooler exchange corrosion radiator leaks due to corrosion etc. I was going to convert the EGR to oil system....basically run the oil filter bypass hoses thru the egr. though was if I used oil instead of coolant, less corrosion and electrolytic issues. was going to install a free air oil cooler and get away from the coolant oil exchange unit. I already back flushed this and I have a coolant filter to catch dropped coolant suspension debris. so I was wondering...why hasnt someone come up with a waterless coolant system. I was thinking of using 0W5 oil that is used for alcohol powered go karts. this being the thinest highest temp rated oil that I know of. 20 bucks a qt, and probally too heavy for the coolent pump. did some googling and found evan's waterless coolant. its waterless so it elimnates cavitation becuase there are no bubles due to coolant vaporizing...its good to 375 degrees at 0 psi. this means it will freeze in time egr corrosion, cavitation of the coolant pump, oil cooler exchange corrosion, radiatior corrosion. the lack of vaporization will prevent bubbles that interfere with high power temp transfers at high HP operations and help prevent head gasket problems and cracked heads/cylinder ways. this stuff is too good to be true so I had to try it. 8 gallons of prep fluid and 8 gallons of heavy duty evans coolant, about and hour of work, and done. so not im at a waterless coolant system. so this is helpful to egr, radiator, oil exchange, water pump, etc. the only con and for desiels is not a con..its a pro...is that the evan's waterless coolant is slightly less efficent that 50/50 mix. basically this mean the metal in your engine will run 10 degrees hotter. for desiels this is a good thing becuase it improves combustion and reduces emissions. Ive gotton at least a 10% MPG increase becuase of this. expensive....I spent 600 bucks on this...but its supposed to be lifetime coolant. and with my coolant filter cleaniing it up it probally will be. so my list of remaining unreslved 6.4 problems is shrinking fast....a happy day indeed. before folks jump in and start talking about deletes and stuff....remember...where i live they check emssions during the annual safty inspection and the both probe the exhaust on roadsides as well as look under for removed emmssions control system componets....not into paying 1400 bucks to be a carefree spirit and yes I have been road side spot checked a few times. so lets not go there. so evan's waterless coolant gets a thumbs up from me. __________________ [SIGPIC] 2010 F-450 Dually, Harley Davidson Trim.

Super product, although it is not necessary if you have enough coolant to flush system.

This is used to remove all the antifreeze and water, in preparation to install Evans waterless coolant. after testing the fluid. it worked great, the last time I will ever have to change the coolant, and will never have corrosion, a little pricy, but if you plan to keep the vehicle a long time it is actually less expensive.

I've been a fan of Evans products since 2010. The coolants kept my motorcycle & vehicle cool during the 2011 summer heat wave in Houston, TX. The coolant proved extra worthy as the cooling fan in my vehicle stopped working. Not once did my temp guage move past normal range during that summer. Evans Prep Fluid will ensure that all of the existing coolant is broken down & won't affect the properties of Evans Coolant once added. Evans products were even featured on Jay Leno's Garage. Evans Coolant is lifetime so once you transition to it, you'll never need to flush.

Great product

This stuff works as advertised. Its just that once you bleed your coolant system of all your old coolant your have too add the waterless prep fluid. Its best to refill your system with this then actually run your motorcycle around town for 20 mintues or so allow to cool then drain your system refill. Repeat the above steps the reason is after bleeding your block you wont able to get out every last bit of the old coolant when you refill and run your motorcycle you will allow it to fully circulate through your water jacket. You will have to do this about three times before actually filling the system with the Evans powersports fluid.
