De-ionised water for coolant dilution.

[Riejufixing]

Euro Car Parts TRIPLE QX De-Ionised Water 5Ltr £5.39
Tesco De-Ionised Water 5L £1.80

Any difference, apart from £3.59?

One wonders if that is really what is being paid for.....who’s to know otherwise.
Look at vodkas,gins and wine all claiming this that and the other when in fact it’s some cheapo concoction.

Tbh I'd just use tap water for coolant. The amount of minerals in a couple of pints is minimal. Its not like you change it every day.

Buy the Tesco's one and be happy, do not use tap water

On a similar subject ASDA sell dot 4 brake fluid for £3 or something. Haines sell it for £7.
Surely the fact that it's to a strict standard for brakes it's just as good??

Isnt boiled water left to cool de-ionised, thats what I was led to believe anyway. And Ive used the it as that, no adverse effects to report.

[Tankie]

Of course, it's to a standard so there is no problem

I condense water vapour and use that. testing my local tap water its between 360ppm during last years dry summer and 128ppm at the moment after the usual winter rain fall. the end product reads 3-6 ppm so it works!

I used tap water before, as that's what the service manual said, mixed with ethylene glycol, of course.

There is also a theory, that deionised or distilled water (one of those at least) could be harmful to the engine. Everything in chemistry seeks equilibrium and such water could pull minerals/metals from the actual engine. Fun fact about chemistry, if you put stainless steel (reduced carbon content) right on a regular steel, the stainless steel will pull the carbon out of the regular steel and rust away.

To be honest though, it would take a lot of time for deionised or distilled water to eat away enough metal from your engine to cause a leak. The point here is though, tap water mixed with ethylene glycol is not only better for your engine, but also much cheaper.

Really? You’re putting water in your radiator/expansion tank to get the coolant level up to the recommended level according to the manual.
Just get a jug of water and top it up.
If you have to top your bike coolant system up so often that you need to worry about furring up the engine/pipework, you must have one serious leak

I change my coolant on every service and on the very very few occasions I have needed to top up, I have just used tap water.
So far no engines were harmed or felt mistreated with any of the bikes I have owned.

I usually suggest people look in their kettle. If it's spotless, crack on and use tap water. If it's full of scale and chalk, do not.

I've stayed places that had such hard water you would have physical lumps floating in your tea if you boiled the same kettle full of water more than once. I would not put that stuff in my radiator.

Two common and free houshold sources of distilled (not de-ionised) water which will be fine to use in a radiator:

1) The condensate tank from a condensing tumble drier (the type that don't vent to outsid)e. Many are plumbed in but there's usually an option to collect the liquid in a small removable tank that needs emptying every time for if it's not situated near a drain. Usually just need to move a single push-fit hose on the back to switch between drain and tank.

2) The ice that forms on the inside of your deep freeze.

Hmmm I didn't realise there were differences. Interesting that and will look into it.

Maybe the stuff from Tescos has been..... watered down

[chris-red]

If I'm happy to drink it I'd be happy to put it in my engine tbh.

Up Norf the water is clean and pure, washing machines love it.

Darn Sarf they drink chalk straight from the taps. I would only use that out of a water cannon on some lefties.

I've filled every vehicle with tap water and anti-freeze, as already said you're not filling it all the time so no big deal.

I'd use filtered rain water before tap water, but as Stinkwheel said in a soft water area it'd be fine. Tumble dryer condensate or water from a de-humidifier is ideal though.
