Default Coolant Turns in to Water after 3 Months of Non-Usage

Hi,

Earlier I had posted a thread of my car service with bimal and the its costing, from that day till today i had not used my Swift and today when i opened Bonet, i saw no Green colour thing in the coolant box, when i opened the lid i was shocked to see only water and I really dont know how it happened ?

Can someone tell me, what happened to the Green Liquid that was there 3 months back and now all i see is White Liquid which is water and No coolant ? Did it dry by itself, but i havent even started the engine for 3 months....

Please tell me is it safe to start engine and drive or should I call mechanics to home...please advice ?

Did you fill the tank partly with water and partly with coolant? It could have been that the coolant could have been denser and settled to the bottom of the tank. I dont think starting the car will cause any problems. Rather it should mix the coolant and water again.

BUT WAIT FOR EXPERTS TO REPLY. I AM NOT VERY KNOWLEDGEABLE IN THESE MATTERS!

Do NOT worry. Even if it is all water it is NOT a problem. Start the car & let it warm up. Coolant is made up of mostly water.

Thanks for the reply guys,

I dont know how bimal filled Coolant and Water Ratio, but when i brought the car from Service, it was thick Green colour Liquid and now its Water.
Well as scuderiamania said, if all coolant has settled down somewhere in the Radiator tank, Its not a problem i guess since it will come up when engine starts and runs for few km.

@1Self Are you sure water alone is ok? because Company says Engine Coolant is must.

Water is the coolant.

It is not coolant + water: it is water + additive.

The colour comes from additives that do stuff like protecting your engine from rusting and, in the cold places, stopping the coolant from freezing, which could destroy the engine.

It is the water that is most vital, but those additives are important for the condition of your engine.

A short time on water alone should do no harm, but the coolant mixture should indeed be as per the company's specification.

Very very true; car engine coolant contains 99% water + some additives. See this for more information on engine coolant. If you're that skeptical, take it to service centre & ask them to top up/change engine coolant.

Why don't you check all fluid levels ( including battery), try starting the car ,take it for a round, and see if the coolant color is restored.

The additives can't have disappeared, must've settled down.

BTW, one of my friends coolant had leaked out from his accent and he has been driving on water for about 2 months now.

To add to TEG sir explanation, It also helps in increasing the boiling point of water, there by helping to increase ability to transfer the heat from the engine.

Absolutely bang on. This is my thoughts too.
