Never heard of it till now. Has anyone personally used it on their 300?

I'd like to know as well as I'm planning to use Evans with my 2.4 Puma once he's all OK again.

The thing that you need to think about, is that once you go to Evans you can’t top up with water in an emergency. So, if you travel anywhere where you can’t get Evans, and you don’t carry it with you, it might be problem.
I can’t comment on its effectiveness, I’m sure it does what says, but what problem does it solve? Is the standard system inadequate? 2007 110 TDCi Station Wagon XS |

It tends to run the enitre system hotter.
The advantage is it cant boil so in theory you can push harder. Though ive not read the best reviews for it. Instagram @defender_ventures Empire Tuning - Agent |

Following comments from the Aussie LR forum aulro.com. Not very convincing that this is a good idea I think.
And if you do a search on here you will find several older discussions about this stuff. Also not very encouraging, Eric I really can't point out enough how much worse Evans is for cooling... It's Specific Heat is only 60% of a quality 50/50 Glycol Mix. It increases head temperature by 45-60 deg C.. It reduces nucleate boiling but does not remove it. It's highly flammable (125c) - a leak onto a hot manifold or turbo is far more dangerous. It's viscosity places additional stress on water pump and increases pressure through cooling system jackets / apertures due to this. It is an aftermarket Propylene Glycol - it is hygroscopic; as it ages and draws moisture.. well Puma 2.2 Radiator Silicone hoses Here was the result of some testing of Evans Claims: SUMMARY OF FINDINGS -Conversion costs of $259 if you do it yourself, or over $400 if you pay a shop to do it. -97%+ removal of all previous coolant is mandatory in order to prevent corrosion. -Inhibitor deposition occurs on aluminum surfaces, which could cause issues in some radiators. -Engines run 115-140oF hotter (at the cylinder heads) with Evans products. -Stabilized coolant temps are increased by 31-48oF, versus straight water with No-Rosion. -Reprogramming ECU fan temp settings is mandatory to prevent the fan from running continuously. -Specific heat capacity of Evans waterless products ranges from 0.64 to 0.68, or about half that of water. -Engine octane requirement is increased by 5-7 numbers. -Computerized ignition must retard engine timing by 8-10o to prevent trace knock. -Engine horsepower is reduced by 4-5%. -Accelerated recession of non-hardened valve seats in older engines is possible, due to brinelling. -Viscosity is 3-4 times higher than what OEM water pumps are rated to accommodate. -Coolant flow rate through radiator tubes is reduced by 20-25% due to the higher viscosity. -Race tracks prohibit Evans products because they are flammable and slippery QQ You never actually own a Defender. You merely look after it for the next generation. http://youtu.be/yVRlSsJwD0o https://youtu.be/vmPr3oTHndg https://www.youtube.com/watch?v=_GtzTT9Pdl0 https://www.youtube.com/watch?v=ABqKPz28e6A https://www.youtube.com/watch?v=rLZ49Jce_n0 https://www.youtube.com/watch?v=XvAsz_ilQYU https://www.youtube.com/watch?v=K8tMHiX9lSw https://m.youtube.com/watch?v=dxwjPuHIV7I https://vimeo.com/201482507 https://www.youtube.com/watch?v=ZSixqL0iyHw |

as above, nothing can really beat water as a heat carrier and it's obvious bonus of being available anywhere if required, and as we all know Landrovers require water at some point when we least expect it. With Evans Waterless, you cannot use water at all and anyway its well known that engines on the stuff run hotter by quite a bit.
Evans is a products that's inferior, but marketing has somehow made it superior..... work that one out becasue it makes no sense to me. |

As stated above it is all marketing hype. Having spent a number of years in engine research and development I can assure you that if it had all the benefits claimed by Evans then engine manufacturers would be fitting it as standard. By far the most cost effective coolant for all climates except the most extreme is a mixture of water/antifreeze at 50/50. Defender 90XS SW

To be honest I’ve never been convinced about it.

Hi All!
Definitely an eye opener for me! Many thanks for the feedback! All y'all just saved me a big expense! One of the advantages of bouncing ideas off our collective!  |
