Guys, I recently got the old zen serviced and used Delphi antifreeze. The mechanic asked us to buy 2lts but only one was used. Now I need to get my Swift serviced and am wondering whether the remaining bottle of Delphi is good enough for Swift or do I need to buy the more expensive Castrol antifreeze!

One it is expensive and two, it is expensive. Primarily used where Ethylene Glycol is banned otherwise the 70% water + 30 % Ethylene Glycol (Anti freeze+ rust inhibitor) is the techno commercial pick at the moment.

Go with Delphi. For all we know Castrol is buying the stuff from some manufacturer and milking their brand by affixing their brand on the packaging.

Thanks! I am planning to go servicing tomorrow and got the answer in time! Now, I am waiting for someone to answer my engine oil question as well (GS Caltex 5W30 Kixx G1 fully-synthetic).

Do you if Delphi antifreeze is non-silicate based? Maruti recommends non-silicate based antifreeze.

Everybody is discussing the proportion of Coolant but none is discussing- How to drain the old coolant completely when the Engine is Cold? Draining the coolant when Engine is Hot will not allow to flush with cold water after draining.

Any help on my above points is welcome.

Just as you can't drain entire engine oil, coolant also can't be drained completely.

However, you can drain the coolant by removing the drain plug from radiator, then filling the entire system will distilled water. Run the engine for a few minutes till the radiator fan switches ON. Allow the engine to cool and then drain the water.
Fill it up with coolant and distilled water.

Flushing is not needed if the coolant is replaced as per recommended interval.
Rust inhibitors in the coolant is used-up over time and that is why replace it periodically.
It is better to replace the thermostat every 4 years as they are known to get stuck in Indigo.

I have bought Tata Toyo Coolant which recommends to use 7 litres of water with 1 litre coolant.
What proportion to be used for Indigo XL Dicor and Xylo E8 ABS?
Is it ok if I use 3:1 Distill Water: Coolant for both above vehicles?

It is time to change the coolant on my ride so this got me reading about coolants.

There is a lot more to coolants than just the color. It is very similar to oil grades.

I found this information -

Groups of Coolants
Let us begin to sort this out by pointing out the three principal groups of coolants. We will not define every possible coolant and its corresponding color. Indeed, yellow coolants may have very different compositions. A blue coolant may have the same formula as a red coolant. The three basic divisions include the following:

Group 1 - the original glycol-based “green” antifreeze we are all familiar with. They have quick-acting silicate and phosphate corrosion inhibitors that do a good job inhibiting corrosion on both iron and aluminum surfaces. This familiar green liquid has proven its worth in all the temperature extremes of North America. Virtually any vehicle can use this fluid. Why not make this the universal coolant? You could, and maybe we have, but the corrosion inhibitors have a very short life and the antifreeze must be changed every other year or every 30,000 miles. If the customer fails to perform this maintenance, then expensive radiator, heater core and pump replacements soon follow. Unfortunately, many motorists do not keep up with maintenance, even with encouragement from their mechanics.

Group 2 – coolants based on the organic acid technology (OAT). They contain 2-ethylhexanoic-acid or 2-EHA and other organic acids, but no silicates or phosphates. This formula gives longer life, thus replacing the short-lived silicates and phosphates. Many colors reside in this group. General Motor’s OAT-based DexCool is orange. Volkswagen-Audi has the same formula, but it is pink. Honda has one coolant dyed a dark green, which looks almost black when it is dirty. The corrosion inhibitors in this group are slower acting, but longer lasting. Five years, or 150,000-mile intervals are often recommended in this group of coolants.

Group 3 - the group of hybrid OAT coolants called G-05. They do not have 2-EHA but use other organic acids and add a little silicate. Silicate is desired because it provides quick-acting protection for aluminum surfaces. Silicate will also repair minor surface defects. Chrysler, Ford, and many European manufacturers are using these hybrid OATs.

NEVER EVER EVER MIX COOLANTS

This is what can happen.

My car has completed 66k and it is time to replace my coolant since it is very much below the minimum level. Ford recommends the following coolant:

Name: Motorcraft SuperPlus Anti-freeze (WSS-M97B44-D)
Color: orange
Capacity:6 lts

But the problem is that I am not able to find the above coolant online in India. Can anyone either tell me the website where it is available (if it is) or any other equivalent available coolant? Moreover, I am also confused with the process of refilling. Do I have to drain the existing coolant and then fill it up with 6 lt 50/50 coolant/distilled water mixture? I have also heard that the front of the car needs to be jacked up so as to let the air bubbles out. Is it true?

Also please tell me if I should run the car with the present level coolant or fill it up just with water till I buy the new one?

Can someone please confirm quickly in Glysantin G30 is a good choice for a 2013 Hyundai Fluidic Verna Diesel? Many THanks!

Are you not considering using Hyundai's OEM coolant? That would be the safest IMO.

Hi, I am confused whether my action was right or wrong. My I20 crdi is 75k run and I10 Kappa2 is 55k run, I recently bought an ethylene glycol based coolant and topped it in both the cars.During previous service, Service executive has told that the coolant is "some glycol".

After topping up I just casually searched in the Hyundai website for the specifications and it was mentioned the coolant type is LLC(Long lasting Coolant). AFAIK LLC means OAT(organic acid coolants). And we are not supposed to mix the Glycol based coolant with OAT coolants.

I walked into the service centre today for verification. I did not take the car as today is saturday, as it is less likely they will entertain impromptu service on a saturday.

I told my predicament to the person on the service counter. His advice was "Sir, there are green and blue type of coolants, but colour does not make any difference. I tried reasoning that its not about the colour I am worried"about. He directed me to the workshop floor for further clarification.

On the workshop floor(accompanied by a staff) I found a boy mixing the coolant with water and requested to see the coolant can. It was a Servo-Long Life coolant with no details of the component. I probed further with a mechanic on the floor. He told "Sir don't mix any coolants, this servo is the best but the composition is classified information".

I told him that I am not going to start a company competing with Indian oil, I just need to know what was the base(it is supposed to be written for toxicology purpose) component in it. And just threw a casual comment of it being some inferior quality when compared to castrol,delphi, wurth etc.which probably hurt his ego. He then committed "it was an Ethylene glycol based coolant with special mixture for hyundai cars".

And Kung-fu Panda has taught about special ingredient, hasn't he?

Any comments?

As far as I remember, Hyundai uses SERVO products, coolant is LLC and of color Blue. I change/flush coolant every 30K on my i20 CRDI. And many of technicians they are not aware about all these ingredients, they were told to use or replace . They will do it but they dont know why they are doing it.

One simple example : There was a door rattle in my car, Hyundai tried to fix it in every service. Every time when I complain about rattling sound, they used to remove passenger side door pad, fix some double side tapes with some sponge kind thick sheet and used to fix it. Almost five years over, couple of months back, one day I got irritated with this sound , I thought today I'll fix it or I'll break it and I'll order new door /door pad. I found that the problem is not in front passenger door it was the problem in the rear left door. The screws which holds the speaker was came out and the speaker was making this noise
Tighten the screws and removed all the packing and tapes from the front passenger side door. All well now, touch wood.

Hello everyone. I have been using 100% coolant in my Indica since 18 years and never faced any over heating problems. Infact when the engine was opened to put new pistons three years ago, the service centre people complemented by saying that they had never seen a cleaner engine than this one before. I use Golden Cruiser.

Coolant has nothing to do with the cleanliness inside an engine. If your oil changes are well within the required time, the internals should remain fairly clean.

Btw, why ever did you need to change the pistons of a "clean engine"...!?

Your FNG is possibly using pre-mixed coolant.

[sgiitk]

100% coolant will raise the freezing point, and will also reduce the cooling. So definitely not advised.
