Saw this stuff on Wheeler Dealers the other evening...

Worth trying in a FFRR?

Apparently never needs changing - good for -40C to 180C... Reduces corrosion etc etc...

i saw that as well and if you can flush the system properly then its a good option..

i liked the bit where Ed China took the pressure cap off when the engine was hot... ... - .- -.

Just wondered if anyone else has tried it - looking at the costs, it won't be a lot more than the cost of the proper anti-freeze for these cars - and that needs changing regularly.

When I was at Car Fest North in September they had a huge stand about this, I didn't understand at the time what it was about. Looked a faff to flush everything properly though. If your coolant has the right corrosion inhibitors it shouldn't be a problem though, especially in the UK.

In the Nordics or Africa/Australia, maybe its worth it? Discovery 4 HSE

Even engines run on the right stuff for 20years will have deposits in the system as the only way around it is using pure water, ie de-ionized type stuff normally for irons as its got little impurities left in it to react with.

I can see the sound basis for this and the pressure reduction in the system is a good thing.

not far off 18litres is in a TD6 system though so that could be fun and ££ to change out! FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

£65 for 5 litres!!
Prep fluid is £40 for 5 litres...

So lets say £200 all in for a TD6 and then another £120 for enough prep fluid to clear the system out... FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

The prep fluid is (apparently) re-useable as long as you filter it. So you could do all the cars in the street...

this stuff sounds to good to be true , however i wont condemn it untill further research is done , if it was proven then i guess i would give it a go 1990 3.5 v8 defender

Caterpillar have a similar product for all their engines. Might be a cheaper way of doing it or check out other large motor manufacturers to see what they use.

Is there not a balance though regarding pressure. I thought the idea of running a pressured system was that it helped to push the coolant against the sides of the engine to get a better contact and thus better thermal energy transfer? V8 or else ...

Possibly, but the main benefit of running under pressure is to increase the temp at which the water boils  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

There is a similar discussion on another forum and one of the members found the follow:


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 so Engine octane requirement is increased by 5-7 numbers.
Stabilized coolant temps are increased by 31-48oF, versus straight water with No-Rosion.
Reprogramming fan temp settings is mandatory to prevent the fan from running continuously.
Specific heat capacity (heat transfer ability) of Evans waterless products ranges from 0.64 to 0.68, or about half that of water.
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 when spilled.

I can't vouch for the accuracy and obviously some of the points won't be applicable here, but there are some points worth considering if true.

That never get mentioned on Wheeler Dealers.................

Obviously a bit more investigation is needed before you pay £320 odd is ? it all in, to change........ 2011 Range Rover Vogue SE 4.4 TDV8
