Coolant / Anti Freeze

[Xulfiqar]

if its the inorganic old silicated coolant, - its a 1 year lifespan. Dont use that, its for ancient engines which had copper and brass radiators. It also clogs up systems if you add hard water to it or mix other coolants with it.

[smshahbazalam]

may be mention on bottle, becoz website pe to mention nahi hia, bhai....40K bhi buhat hay....and you can see as the coolant start changing color, like green to dark green and goes toward brawn, flush it and change....

video may helpful to you.

Use liquimoly concentrated for 1200 per litre and add distilled water to make it 50-50 according to radiator capacity.
Toyota LLC is also amazing, and if you want to go for cheaper go for caltex. But never expect 200rs per litre coolant to be considered a coolant. Its morever a biryani wala rang mixed in water rather than a additive.

that why i posted here to get advice which will helps me to choose the good coolant

coolant can be checked by checking through a multi meter.

as per this procedure, even guard coolant is good as ive tested it in my nissan pino. although i have caltex coolant 3 liters lying around in my house but ill check the guard anyway

thanks for info, i will try this

Dear Sir @Xulfiqar, there are some information available online where people say to adjust the ratio of water and antifreeze/coolant concentrate according to the climatic conditions of the area. This means that the ratio should not be always 50:50, it must be altered like 60:40 or 70:30 (water : antifrerze/coolant).
The reason they quote is that the cooling feature is contributed solely by the water contents in the mixture and not by the antifreeze/coolant, while the later prevents rust and freezing only.
To me this information may not be correct, had it been so there would have no reason for existence of premixed type coolant/antifreeze.
Premixed type coolant/antifreeze clearly states on the label that do not add water, the mixture contains water and antifreeze by 50:50 ratio. To check this, I tried to search labels of different premixed type brands and they all say the same thing i.e., do not add water. Moreover as a practical example, we have abundant of Japanese cars (Japan is much colder than Pakistan) here in pakistan, people buy and drive them with whatever coolant filled in the radiator with no issues of heating up etc., no one actually cares to readjust the ratio of water.

Your expert opinion is sought on this matter.
Thanks

I have not found any need to adjust the water/coolant ratio in any place in Pakistan unless you are driving on the siachen glacier.

Or your vehicle cooling system was designed or serviced by stoned imbeciles.

So this clearly rubishes the idea that the concentrated coolant shall be mixed with more quantity of water than the ideal 50% by volume, to make it suitable for the hot weather conditions of Pakistan.
And that the 50:50 water and coolant ratio is an ideal all season mixture.

[Xulfiqar]

yes - the 50/50 ratio is suited for 99% of all habitable places.

The only few times I have needed to adjust the coolant mix was when I was stationed at a place where winter was -38C. - at those temperatures, the 50/50 mix coolant acts like a gola ganda slush.

so a bit more was treated to it.

[Xulfiqar]

I dont like the flushing procedure in that video, its better to use a pressure motive from the bypass and flush the junk out backwards - after using a descaler/cleaner.

Thank you so much Sir @Xulfiqar, you cleared the doubt that lingered for quite a long time in my mind.

Toyota coolant is best coolant and its 3.8 liter bottle around Rs. 2400/-. It is pre-mixed and no need to add water. This coolant is also available in 1 liter international packing. Ever use coolant in supplement water bottle. Guard coolant can be used.
Before using coolant radiator must be services and lines should be cleaned.
Lines can be cleaned adding 2 Tabble Spoon diesel with water in radiator to cut the rust and after 2 weeks whole water should be flush and insert totally coolant.
Always use well known brand coolant instead fake green color coolants available in market, which can damage the water lines.

i quote "Lines can be cleaned adding 2 Table Spoon diesel with water in radiator to cut the rust"? lol. what kind of jugaar is this

[Xulfiqar]

Rs 1200/- for 1.9 litres water? Must be very very special water

[399.ak]

Is it expensive or cheap??

5 liter laboratory grade distilled water bottles are readily availble for Rs 100~120 at almost all scientific supplies stores.

[Xulfiqar]

exactly my point.

why pay for premix coolant, its bottled for idiots who dont know how to mix two liquids.

[Xulfiqar]

I believe using some narcotics is also a requirement for this.
