distilled/deionised???

Tech spec says my 02 blades coolant/anti freeze should be a 50/50 mix of coolant (ethylene glycol) and distilled water...

i know they're slightly different in purity, but would there be any harm in using deionised water in place of distilled?? the price difference is crazy!!

coolant

is very important and the correct fluid/mixture should be used for alluminium engines.

This means motorcycle anti/freeze (no silicates) not car.

Also distilled water will not create build up of mineral salts inside the engine/radiator.

I would not use deionised water because it`s only filtered.

Think of your summer cooling and waterpump.

Water..

Distilled water is very pure but requires a lot of energy to make, being boiled and the condensate collected. De-ionised water is a more modern technique involving chemical filtration and results in a similar water quality, certainly for our purposes.

cheers guys...

decided that i would foot the bill and go with what Mr Honda says and bought some Distilled water from a company that supply pharmecutical and research labs...

would rather pay the extra few pennies.. than risk damaging anything... it wasnt so much the cost.. it was more that you cn get deionised from any motorfactors.... distilled is a bit harder to source...

You'll have paid for super-pure, sterile, analytically-certified water. Rainwater is distilled.

Rainwater.

It's distilled until it has run off the garage roof into a filthy water butt, it's true, but with care you could collect the good stuff straight out of the sky.

Rain water

It's still not distilled as such(or rather it was) when it falls it gets contaminated by the atmosphere, so is no longer distilled. :smile

Put it this way, if you're breathing the air without being poisoned by it then the rainwater that falls through it will be acceptable. It will be pure enough to mix with radiator coolant anyway.

My point is that de-ionised water is good enough. Limescale is your real enemy here, and rainwater will have none. A Brita water filter will do the job in that respect too.

Limescale

James has it correct, just above.   The problem with tap water in radiators is that it'll cause them to fur up, just like in your kettle.

On the other hand, if you live in a "soft water" area such that your kettle does not fur up, that tap water will be fine for your radiator.

Note that even "soft water" - the decent, honest stuff we get in Wales - will be absolutely no good for the battery.  You need distilled water for that.
