Best Coolant for Suzuki Hustler

[asharibhassan00]

Hello guys i need help from you guys
So i recently discovered that my coolant is very low to almost none and i need to put a coolant in there and im not sure which one should i get and how many litres would i need. There are many options in the market but i want to know which will be the best one for me.
When i bought this car the coolant was there already so i didnt know what coolant was being used in the car before.
Thanks alot

Car : 2014 Suzuki Hustler (non turbo)

Do not mix coolants. Use what was already in there to top it off.

If you want to exchange all of it, completely flush the system and refill with desired coolant.

Do a bit of research online, there is lots of information available.

What is the color of the existing coolant ?

If coolant seems neat & clean, and just
need little top up, then just top it up with RO Water or Distilled water. That’s
all.

There are various types of coolants available
in the market

Green one are like short life. You change
it after 20-25K or every year.

Pink one are usually OAT based coolants which
very long life like 100-150K km.

Orange Ones are usually concentrated. You
have to add equal amount of water by yourself.

Search the chassis number on different
websites to know the exact required quantity and choose the coolant according
to your needs.

Search the Xulfiqar’s messages here at
forums. He has described many times the correct method to change it and also
the types of coolants.

The coolant is very low in amount and someone suggested me to use mineral water only as the coolant coming in pakistan nowadays are not original, is it ok to put mineral water in there?

Someone told me that the coolants coming in pakistan nowadays aren't original and authentic and i should use mineral water instead. Is it ok to use mineral water only if there is no coolant left in the container

Whoever that is, you should not listen to them ever again.

Coolants can be found genuine, however they will be 'pricey' compared to your mediocre coolant brands like Carrera, which is just garbage in a bottle. Ensure when buying, you buy from a reputable source to ensure it is genuine.

You can use distilled water to top up, but do not use it in the entire system as it is not safe either.

Use either genuine coolant from a reliable source, or caltex coolant mixed with distilled water after flushing the complete system.

Do not listen to roadside thermostat removing fan direct Karna waala ustaad. They will destroy your car in a matter of months.

I used Suzuki ecstar genuine coolant from local dealer in my 2015 every turbo. I believe we have the same r06a engine.

Everything's fine with mine.

If you have anything you are unsure of, use Google. Honestly, lots of information is available at your fingertips.

Thanks I will see about the coolant, can you guide me about the flushing of the radiator should i do it or no and if so which liquid to use

[affanhaq94]

You first need to see why the level went down.

Either a leak or it just needs topping up. If I was you, I would top it up for now and see if the level stays consistent. If it does, fine. If not, inspect for leakage.

If it stays consistent, it may be beneficial to change as the vehicle is 10 yrs old. However, refer to your owners manual for proper change interval listed there.

Also, whoever is going to perform the work, ensure they know 100% what they are doing. These unqualified desi mechanics usually always screw something up which ends up costing us.

Was that someone high on drugs? Or was devdas when his girlfriend left him?

All major brands with agencies in Pakistan sell engine coolant product, you can buy those very easily and if you suspect its authenticity then just call their distributor and ask where to buy it from.

Do not try to modify or re engineer the cooling system because “someone told you” the only someone you should be following is the manufacturer and their provided owner and service documentation.

E.g. it you listened to some idiot who said to throw away the thermostat and run with mineral water instead of coolant then its 100% going to fail catastrophically.

And if your repair would be “radyator service with rods being poked in it, siliconing the tanks shut, filling tap water and praying it doesnt leak” then you are to blame.

Your repair should be to fully clean the entire cooling system 100% and repair all fail points, then refill coolant and water mixture or prepared coolant mixture.

My family friend bought some 2008-9 model Baleno and it was running with direct fan and with 20w-50 motor oil.

I suggested him first to pay attention on the cooling system and follow the flush method and then use coolant and keep this fan on auto mode instead of direct. And use 10w-40 which is recommended by Suzuki.

He replied the previous owner was running with direct fan since years so why I cannot? Since car runs fine in city and on highways too and there are no over-heat issues. And I kept quite.

Last weekend we met and he told me he put up this car on sale because of too much troubles/mechanical problems. I just listen to him and kept smiling inside

That someone is probably a radiator wala just waiting to get their hands on your car so that they can start milking money from you every by destroying the cooling system and making it fail over and over again.
For Japanese cars, the Aisin coolants are best. Go for either the green or the red one and roughly 4 liters would be enough but obviously a bit of research is required.
I've been using Aisin green coolant with regular change intervals of 50000 km in my PKDM wagonR and after 180K kms there is still no issue in the cooling system.
To flush the cooling system:
1. Drain the coolant system.
2. Use LiquiMoly radiator flush or use flamingo radiator flush if you cannot source the LiquiMoly flush. Pour the flush along with distilled water into the radiator and top off with more distilled water until full.
3. Run the engine for 15 minutes approx. making sure the cooling fan turns on once or twice atleast (ensure that the thermostat has opened allowing the water/flush to fully circulate)
4. Wait for engine to cool down. Then drain raditor and refill with distilled water only and run the Engine again until it is warmed up and cooling fan turns on once or twice.
5. Repeat step 4 three or 4 times if you want to get most of the flush out of the system.
6. Now fill the radiator with coolant only, if using Aisin it is premixed so no need to adding water separately to dilute it. If using caltex or some other concentrated coolant then you may need to add distilled water in the ratio mentioned on the coolant bottle.
7. Immediately after filling the coolant, turn the engine on with the radiator cap still open. You will notice that the coolant level has immediately dropped, Top it off again and wait for a while until the level does not drop anymore then put the radiator cap back on securely and let the engine warm up to operating temperature.

Ok thanks a lot just one last question is it necessary to flush the cooling system or I can just put the coolant would it be fine.

edit : should i order the Aisin coolant from daraz?

[pwuser166331039855]

one important thing you missed. i-e turning on the cabin fan and set the knob to the max. hot.
doing so will allow coolant to run through the heater core too which is important.

if its T-Valve is easily accessible, then better remove it while flushing. And install the new t-valve with new rubber O-ring.

would be better to change the radiator cap too if its rusted by any mean.

edit : should i order the Aisin coolant from daraz?

these are pretty commonly available in market.
i saw plenty of them at Makki oil store during my last visit.
did you decide you want to use pre-mixed coolant or concentrated one ?

QUESTION: Ok thanks a lot just one last question is it necessary to flush the cooling system or I can just put the coolant would it be fine.

ANSWER: Sir, this question has been answered in great detail above. 1 - You should not mix coolants as you don't know what was there before. Let me say that today there are a multitude of coolants relating to different technologies. Here are a few types of coolants so you may have a greater understanding as to why you should not mix:

a - IAT (Inorganic Additive Technology) Silicates generally for older vehicles not so good with some aluminum radiators. Good with copper/brass radiators.

b - OAT (Organic Acid Technology) Organic Acids (good with modern alu block/head/radiator also long life typically 5 yeas or so)

c - HOAT (Hybrid OAT) Silicates & Organic Acids

d - HOAT (Hybrid OAT, Phosphate-free)

e - P-HOAT (Phosphated HOAT) Phosphates & Organic Acids

f - Si-OAT (Silicated HOAT) Silicates & Organic Acids

Not all are mixable with each other.

So if you are insisting on adding coolant, there is no way but to drain the system, refill with water, run the engine, drain the water and fill with 50-50 coolant water mix as excellently explained by @aminjafer5441 in much detail.. Please keep in mind that you will never be completely empty the system. There will ALWAY be some quantity of old coolant remaining. That is why a water flush is done so as to dilute the old stuff as much as possible.

Now, 2 if you just want to add stuff in the expansion bottle so you can see the level, as already mentioned, you can add distilled water or bottled drinking water. Based on our ambient temperatures that does not go below freezing, you can go as low as 30% coolant and 70% water so the 1-2 liters of water added in the expansion bottle will not adversely effect the concentration and freeze protection. Ideally the recommendation is to stick with 50-50.

Question: edit : should i order the Aisin coolant from daraz?

Answer: What grade is Aisin coolant? IAT or OAT or HOAT or P-HOAT?? Do a bit of research. Gain knowledge. Then proceed with ordering.
