Which water to use for radiator

[pwuser158303446462]

AOA what type of water is best to use for radiator as currently im using tap water and heard somewhere that A.c water can also be used

[aziz.rehan]

Only coolant should be used

[pwuser157223660331]

Coolant should be used in radiator. otherwise radiator will corrode.
AC water has low impurities thats why some people suggest using it.

[pwuser158303446462]

Ahan i see
Can u suggest me some good coolants?

[aziz.rehan]

Caltex,aisin,toyota.

[mshoaib432722]

Caltex, toyota coolants are best but not so "mild".
If radiator.is already rusted then you have observe some leakage so better to go for something milder for the first and then subsequently caltex, toyota coolant etc.

How to inspect if radiator is rusted
As my one car is driven 58k and second one 10k

[azfarnb]

This doesn’t make any sense. Whats the make and model of the car thats driven 10k? It should have the factory coolant of the manufacturer. And are you using tap water in both 58k and 10k driven cars?

[pwuser158303446462]

Yes brother im less knowledgeable in these things so plz advise which specific water to use
Grande 2018 is driven 58k and im using tap water
Civic is 10k driven 2019
I check the radiator water every week and if they are less than fill it with tap water

[aziz.rehan]

How did cars this new get tap water in cooling system anyways.especially civic.

[pwuser16017162507]

Use Sting (red one) it will boost performance by 10%

[ahmadusaf]

Distill water can be used or not?

[pwuser158303446462]

Brother did some research and now checked the radiator water
In grande it is orange/yellowish does that mean the radiator is rusted?

[aziz.rehan]

Lol

[aziz.rehan]

Not.use coolant.It,s easy to use.First flush the radiator 2-3 times until u see clear water coming out.Then add coolant and make sure there is no air in the system.Some coolants are prediluted means u don't have to add water.And some are concentrate means u have add distilled water and keep 50:50 ratio.Coolant has many benefits,ur system will be free from rust and ur engine,s, radiator,waterbody, thermostat valve life will be increased.

Post a picture to see how bad it is

[mgalaxy3]

Ah...

Tap water in such new cars? The previous owner was also using water?

Bro just go to dealership, get genuine coolant, ask them to flush radiator n fill the applicable coolant in it.

[farooqk80]

Do a Citric Acid Flush and add caltex coolant by mixing it 50:50 with distilled water.

Did someone tell you to

“Tel aur pani roz check karo”

????

To check coolant level all japanese car makers have provided a transparent expansion tank with min and max markings

As long as the level is maintained there its ok. The radiator cap is only checked if

The coolant tank is fully empty or fully full.

Otherwise it should remain closed.

[pwuser158303446462]

Yes sadly brother that is what happened with me
However i researched in some detail yesterday and found that if the reservoir is full no need to check
Furthermore i will attach some pictures and plz i would be more than happy if someone assisted with the whole process of flushing and installing new coolant
