## Overview

Cooling Systems EC42001 Waterless Prep Fluid is a 128 fl. oz. specialized solution designed to thoroughly flush out residual coolant and water from your engine’s cooling system. It ensures optimal water content levels before installing Evans Waterless Coolant, protects cooling system metals during the flush, and is essential when block drains cannot be used. Ideal for professionals seeking to maximize engine cooling efficiency and longevity.

## Description

Evans Prep Fluid, EC42001, is a waterless cooling system flush engineered specifically to purge the cooling system of water and water-based antifreeze after draining and before installing new Evans Waterless Coolant. Prep Fluid should be used when block drains are unavailable or cannot be removed. It is not a substitute for thoroughly draining the cooling system and related components. Prep Fluid is not intended to be a stand-alone operating coolant, but as a flush only. Evans Prep contains a bittering agent/bitterant.

Review: its good to 375 degrees at 0 psi - 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.
