Personally I'd avoid something like waterless coolant.
It turns something that can be easily maintained into something that is a bit bespoke, for questionable improvement on a std engine. I know that Evans is used for some people who tune engines where hotter engine temperatures are the norm and therefore need a solution. I would just drain it, replace it with a decent concentration of the std fluid and replace it in 5 years time or so. They do have a service interval. Cheers Andy |

I'm also considering Evans coolant, on the basis it doesn't overheat, good to -40 and doesn't pressurize the system quite as much, so less expansion or pressure on seals, gaskets and hoses.

I looked at Evans, as I am using a tuned 4.6 v8 in my 90, I came to the conclusion that it's basically an over hyped, expensive liquid, that's flammable.
As long as you have a healthy radiator and hoses, normal anti freeze is more than capable. |

lets be real here
if your defender is having an overheating problem, something is broken.. unless your defender is a performance machine or something..... |

If waterless coolant was that good then why wouldn't manufacturers put it in from the factory? I agree that regularly replaced standard coolant and deionised water is perfectly adequate.

we ran this 4 years ago or so on a heavily tunned td5 auto for Croatia. it worked well to help with cooling, but is a long old filling cycle to get all the water out plus its £££££££££££££ for not a lot was my conclusion.
Plus on day 5 or so when a branch took out a rear rad elbow and we lost the lot we had to drain and fill with water anyway...  Cheers

^^ Interesting read and findings on aulro.com. So much for that idea.
Think I stick to my practice of having the standard water/antifreeze coolant mix replaced every few years. I don't like Land Rover's recommended coolant flush/replacement at 200.000KM only. Seems a bit long to me to remain assured that all anti-corrosion inhibitors and other additives in the antifreeze solution still have their full working capabilities after such high mileage. If I remember well, in the past 8 years and 80.000 KM my coolant was replaced already twice, last time with the installation of the PEL500110 thermostat. Gives peace of mind.

GDay fellas.
I'm the person who was asking about Evans in Oz. As per the thread, I've decided to stay with OEM coolant and regular changes. We often operate in above 40 deg c temps, and I often tow a 2 1/2 ton van, so will stay away from it. An EGT gauge and accessory water temp gauge is high on my list of mods though. Best wishes all.

Well it's looking like the general synopsis is to stick with the conventional arrangement.
So on that basis, can anyone shed some light on the various questions raised in my original post? Based on the rusty brown colour in my vehicle, I am keen to replace soon ... Cheers. |

^^ Answering your question 1, my truck is a Puma 2.4, 8 1/2 years old, 80+K km, coolant has been replaced twice by dealer, each time when installing new thermostats, but none of the coolant mixes ever really changed colour, certainly not to a rusty brown or so.

The rusty brown colour, wouldn't be some sort of reaction timing of different types of antifreeze would it? Given its rusty brown and a cause for concern, i would drain and re-fill with fresh anti-freeze and then monitor the colour for the next few months. It might take two flushes to get rid of all the rusty coloured water though. I would definitely check the fluid that is drained though and ensure its a not rusty looking due to some sort of oil contamination (although i would expect it to be milky if oil in the water).
