Evans waterless coolant

[dom14]

On my last coolant change I tried to find distilled water but could only find demineralised. I didn't look to hard tho.

I'm pretty sure it's the same thing. I'll wait for the other blokes here to correct me, if I"m wrong about that.

I buy the stuff from Coles, which is a cheaper way to buy them in bulk. Around $1.50 for a 2 litre bottle.

Demineralised water is what they sell as distilled water, it has the minerals removed through reverse osmosis, a physical process. Pretty much it is pure water.
50/50 with the right coolant is the way to go, don't buy premix as there is always some water left from flushing.

Yeah, I even put bit more than 50% of the rust inhibitor concentrate. The rust at the bottom of the block was probably left overs from previous build up. I didn't use anti freeze, just rust inhibitor, 'cos I thought anti freeze is not critical in Melbourne, unless I decide to spend time in the snow.

I also decided to do an "electrolyte test" with the multimeter & a litmus test as well. Both cost practically nothing.
Litmus strips are fairly cheap.

I've been wondering mate,

Is there a way to get rid of every bit of water(figuratively speaking) after flushing the engine cooling system(exclude radiator)??!!

There's obviously a drain plug on RB30 block, but it's the same level as the welch plugs. I'm not sure it's capable of draining all the water though.

I'm guessing some kinda air pressure method?!!! Any ideas, thoughts??!!!

The "distilled" water from Coles is demineralised water, it is cheaper in a 4 litre especially when you need 15 litres in the system, the Coles stores I have been to have a maximum of 6x 4l on the shelf.
When we tested it years ago it had the lowest total dissolved solids (TDS) of any of the demineralised waters we could find, we use it for servicing wet cell NiCad batteries.
As for getting rid of the last bit of flushing water (the scheme water here has a high % of ground water so is high in TDS) , you could fill with demineralised water, then drain, add concentrate then top up with fresh demineralised water.
With anti freeze it also makes the water slipperier so it will move through the block & radiator better, it will also raise the boiling point, the anti freeze properties are redundant in most parts of Australia.

Thanx for the information mate.

Yeah, anti freeze doesn't make sense for the most areas and times in Australia.
On rare occasions, in late winter the temperature drops to below zero, turning water buckets into ice in Melbourne outer suburbs, particularly in eastern suburbs. It happened last year and the year before here in Melbourne outer east, but not this year though.
Even with that, I reckon it's not cold enough to freeze the water inside the engine. Anti freeze is useful for guys who live in Dandenong Ranges, etc or in hilly countryside.
I would only put antifreeze if I decide to spend overnights in snow resorts during winter, which I don't do, so antifreeze is no use for me. The boiling point get raised a bit with water pressure, so I reckon that's enough to hold it for a while in case of overheating.
I do have two aftermarket temperature gauge units with build in warning buzzers & blinkers, so that won't be an issue.

BTW, I have no idea what a wet cell NiCad is, and I have no idea how you use distilled water in them.
