radiator coolant and spring water

[markus_74]

Hello,

I want to change my spring water is in radiator now and replace it with distilled water plus coolant.

Is it necessary? Or just use spring water and mix with
coolant?

What is the bad effect use spring water?

Thank you
Markus

Unless your water supply is a bad as the stuff that came out of the taps when I used to live in East Kent, then ordinary water mixed 66/33 with concentrated coolant is all you need.
A good quality antifreeze (doubt if they call it that where you are!), at the right concentration, and changed at the recommended intervals is all you need to protect the alloy parts.

Waterless coolant is something to consider. It's expensive but will last a life time. Can drain and reuse.

Yes, I have buy 4.5litre anti freeze coolant vaico brand blue color.

Does mineral at spring water will eat the alloy because act like electrode? And will make sludge?

And what is waterless coolant?

And what is waterless coolant?

Its a coolant that is waterless

A full concentration of antifreeze coolant without diluted with water?

What it doesn't state in the ad. for all this, is that it's not as good as transferring heat away from the parts that need to be cooled as water, and so needs to have a higher boiling point! Nothing (affordable and practical) transfers heat as well as water.
It may have an infinite life, but that's not much use if a split hose pi**es the coolant all over the ground.
A solution looking for a problem IMHO.
The one use it may have is on track, where losing antifreeze on the track doesn't go down too well with following competitors.
Adding antifreeze to water reduces its heat transferring abilities, so the minimum amount of antifreeze to provide corrosion and frost protection is what you should be aiming at. In the more civilised areas of the UK, this equates to about two parts water to one of concentrate.

Have a read of the thread I just put up in the general e30 chat section re waterless coolant
