Evans waterless coolant

[bert977]

Wise ones out there,
The garage fixing my bongos water pump, (Rotechniks of Grazeley, very helpful and bongo wise!) have recommended this new fangled waterless coolant. As it is waterless it runs at significantly lower pressure, (got to be a good thing in an ageing bongo). It doesn't cause cavitation or corrosion, prolonging the life of components. All kinds of race teams/vintage car collectors/users of engines have switched over and i am sorely tempted. It ain't cheap though as the system has to be drained and completely dryed but it is 'fit and forget' and lasts the life of the engine.
Has anyone out there come across this stuff?
kindest regards!

A bit of Google tells me .... It dosn,t boil till 360 degrees.....one result of this is higher oil temps so advice is to fit a oil cooler.....also the fans will run More as it fools the ecu
Why mess about with a perfectly good cooling system.

[Driver+Passengers]

I don't know if I'm right but in the event of an air lock in the head/heaters, and as it doesn't boil as readily, then you won't get the tell-tale expulsion of coolant out of the header tank due to massive volume expansion of a liquid-to-steam state change as early as with water/coolant, so the level won't drop as soon and an LCA won't alarm until things are really bad! In a Bongo, therefore, it might render the alarm less effective as an early warning device and could end up doing more damage than good.

I don't know - how hot will the head get with no coolant?

I put a post on here about this over a year ago was rather afraid to try it, loads of vids on youtube showing what to do etc.

[Driver+Passengers]

Boils at 180 degC, lower coefficient of thermal expansion (hence lower running pressure), but lower heat capacity (water is 'better'). I think in the event of an overheat, it will still behave as water, blowing out pretty quickly. Lower pressure might help to prolong the life of hoses, etc...

I'm sure you'd notice no difference - but I'm not going to spend >£100 to find out.

Hi
Uncle Ed...well, more like Mr. Ed....TV programmes are paid enormous amounts to endorse products, or even show the name of a product in a TV program - so much so that Dutch TV went overboard on this in the '80s in an attempt to stop shameless con. trickery
Waterless coolant works very nicely with airless air.....NO AMOUNT of fiddling will stop air contacting metal, as we LIVE IN IT...and it will promote corrosion (unless Star Trek has changed the laws of Physics - Jim
I'll bet a nice shiny sixpence that all the preparation work involved in "drying out " the engine in preparation for the substance is going to cost more than a tanner?.....
PLUS...now here's the chaser...are this garage prepared to guarantee the life of the components in the coolant system....mmmm....I guess not....As has been pointed out on here , the Mazda Water pumps are not supposed to last indefinitely....radiators burst, head gaskets go, heater components fail, clips on hoses, no matter how good, fail, turbos fail and interfere with the pressurisation of the water system, fan switches, cylinder heads, valves, ......
Oh, I'm sure that an everyday ride will do nicely with an everlasting engine, but fact is fact, components fail, and sure as hell won't be guaranteed by the waterless water company, and here's that sixpence again, to bet that Mr. Ed won't cover the cost of all that lovely damage that wouldn't have occurred if you attended to routine maintenance as you should.
The major problem with advertising such as this, is that you might be inclined to "back shelf" normal maintenance , which will almost certainly result in a catastrophe
Race cars use it, eh?????...Life expectancy , one race if you're unlucky, or possibly a season...never big miles! and they strip them between races...in fact, the legendary super high horsepower Keith Black "Elephant Motors" used in drag racing were more or less expected to fail catastrophically....but, boy , did they make BIIIIG horsepower....
Classic cars....well , do they use the miracle fluid?...I doubt that many do, and if they do, they won't be clocking up 10,000 miles a year, and the owners will be constantly "fettling" them.
Anyone using race cars and classic cars as a hallmark for a product is conning you , as they get colossal amounts of attention, which is precisely what they say your engine won't need once you have the wonder product on board...."Go Figure", as they say across the pond
Almost all supposedly reliable cars suffer damage, just because the owners neglect ROUTINE MAINTENANCE because they are so reliable....that's the bugbear of Mazdas, Jaguars, and so on
Any garage recommending this stuff is doing so because they have been conned into handling the merchandise
Sorry, but this isn't a knock, but advice not to be tempted by pills and potions
Cheers

I am sure Uncle Edd will have a wee chuckle when he reads this.

Hi
I doubt Mr. Ed chuckles...I usually use reliable mechanics if I need a job done...I expect those self same mechanics laugh at the "prowess" of Mr. Ed....especially the program I saw with the Holts tin can re-spray....

My husband is very keen indeed to try this, but as the Bongo is mine, I'm still waiting for someone else to try it in theirs

Funny how he thinks the Bongo is the only vehicle in our fleet worthy of the experiment

[winchman]

So which car manufacturer uses it?
Have I read this correctly or is it not as good at cooling as water?
If the bongo drops its water whilst out and about can you just fill it up again after having the new stuff in it?
I think its still water for me , spend the money on a holiday instead

[helen&tony]

Hi
Winchman...
You hit the nail on the head...I wonder if Rolls Royce use it....Ferrari, Bristol, Cadillac, and dozens of others who don't stint on price....or quality of components....methinks it's just for the gullible, and those who fit whirlygig fuel savers in their air intake....oh, and the "bat-aid" pills for the battery....still, someone will buy it...oh, and don't forget the odd spare gallon for top-up...and what do you fill it with in the event of a split hose?????....anyway, I expect it's also a miracle hair tonic for balding men, and good for arthritis if you rub it in twice daily
Cheers

Hi,

Marketing is a wonderful thing. There is always somebody gullible enough to believe this stuff is suited to road use, or that the earth is flat.

I defy any garage to get every last drop of water out of the complex cooling system on a Bongo and dry it out internally.

Hi
I think the preferred method is a 3-foot q-tip, an endoscope, a proctologist and a lot of patience....

Just to add another point you must use tap water in a cooling system too, if you use di ionised etc it will corrode the internals as the water strips the bits its missing from its surroundings, the purer the water gets the more aggressive it is
