Evans Prep Fluid

Engine Types for Prep :
  • All engines being converted to any Evans Waterless Coolant
  • Use after draining 50-50 coolant and water from the cooling system

Evans Prep Fluid 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.

Ready to Use—No Water Required.

  • Hydroscopically absorbs water
  • Ensures all residual water is removed from the system
  • Ensures that Evans coolants will meet the water content limits and provide peak performance
  • Protects cooling system metals during flush

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.

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.

Expensive!! If you have a leak,make sure you carry an extra gallon...YOU CAN''T ADD WATER TO THIS EVANS!!!. I, like others, thought this product would lower the operating temperature; however, if I read the fine print, all it does is INCREASE the boiling point. It is a good product, but I want my engine to run cool. So for my Boss Hoss motorcycle, I switched back to "Wetter Water" plus distilled water. Distilled water will keep the minerals out of the radiator.

I left block open to the summer heat of Texas to evaporate the remaining water after flush. Jeep book said it took 3 1/2 gallons it only took 2 1/4 of prep. But glad I did cause I was at 2% water after install of coolant. I have enough to prep a hole other vehicle.

Good review from Jay Leno''s garage so I replaced all the hoses on my 2001 Corolla, prepped the system with this, then added the lifetime coolant. Jay''s had it in various vehicles for 17 years with no issues.
