Three points out of my personal experience

1. If you back off the timing, the exhaust port temperatures shoot up. This will cause to overheat. Timing as per the reccomendation's is a must.

2. Pr. cap not only prevents the water from leaking but also increases the heat carrying capacity of water.

3. Always use Demineralised Water (DM) to help prevent scale formation. I have seen mechanics putting Distilled water or Tap water both way is incorrect.

Is TECIL make pressure cap available in the market easily?

How is usage of distilled water incorrect? I am presently using coolant mixed with distilled water. What water is Demineralized water?

Distilled water is free of Germs and bacteria but no of minerals in water. Water from a Borewell migh have salt which will elad to scaling. A demineralised water will be free of minerals.

I know that we shouldnt use borewell water for sure. I never knew about distilled water. I always believed this is best and using it. What are the other best waters to use apart from Demineralized water?

Where can you find demineralized water in Bangalore?

No. Pure distill free of absolutely free of all solutes. Arre, thats the reason its used in batteries as well as injections by doctors. It is harmful to drink distill water for the same reason (absence of essential salts thus, it becomes hypotonic). However the presence (or absence) of microorganisms depends on the storage. Please refer Distilled water - Wikipedia, the free encyclopedia for more information.

So my 4 cars running on coolant + distilled water are safe

Absolutely !! Majority of people use normal tap water and their cars run fine. But we being different would like to do things the "perfectly correct way". What say ?

Absolutely! We all really care for our cars. Sometimes, we sacrifice many other personal things in life just for our cars. We all like doing it.

I flushed all the water out of the cooling system a few times (once with some soap powder too) and then changed it over to coolant and distilled water.

Still not getting it. Demineralised may also be called Deionised water too (also used in Batteries). Distilled water is primarily used in medical and scientific application.

Could it be that the distilled water what we get is actually demineralized? I ask this as I see almost every petrol pump having distilled water bottles and cans

with the borewell water bit! NEVER NEVER EVER let borewell water near a car!! I've had the terrible experience of using the damn thing for one of our cars' radiator, which resulted in it getting blocked up (the salt blocking up all the pipes inside! )
Luckily my mech. then pointed it out and got it cleaned up. 'learnt my lesson then!
'not sure about mineral water though.

Oh yeah! borewell water kills. I think mineral water would do the same thing, because of the minerals present?

If I remember correctly, somewhere, Behram sir stated that tap water is just fine and he is using it since a couple of decades atleast and never saw any issues.

Behram sir, what would the best and most correct way? Is it okay to use distilled water + coolant. I mean does it do any harm having distilled water + coolant?

A heated discussion about the car heating problem.
Is it advisable to use the readymix coolant.This way one can eliminate the risk of pouring the wrong type of water with the coolant. I am using MAK REDICOOL ready to use coolant in my S1.

Definitely! My temperature of my head shot to danger mark (even though temp on my cars dont cross the 40% mark) first thing when I woke up in morning and saw TBHP. I got mad at myself thinking what I considered a good conversion I did (change over to coolant + distilled water) might screw up my cars.

Ready mix coolant! Heard of them. How much do they cost?

Is it okay to use any brand any type of coolant for our cars? I find it difficult to choose from a store. Many dont state properly what vehicle it is intended for. I vaguely remember some types like 'heavy duty' and 'for turbo charged vehicles'

[samsag12]

As stated i use MAK redikool in my car. I bought 3bottles of 1ltrs each for my car which costed 350 total. Directly poured them in (around2.5ltrs) the degassing tank after flushing the old one. Regarding the brand do look out for the antifreeze and boil property stated on the coolant bottle. I don't remember the exact property right now.
