Refractive index is a property related to how light interacts with a substance and is generally not a key factor in engine coolant selection. Engine coolant requirements typically revolve around: Thermal Conductivity: The coolant should be an effective heat transfer medium, efficiently carrying heat away from the engine components to prevent overheating. Freeze and Boil Protection: It should protect the engine from freezing in cold temperatures and boiling in hot conditions. This property is essential for the proper functioning of the cooling system in a wide range of climates. Corrosion Protection: Engine coolant should inhibit corrosion within the cooling system, helping to extend the life of various components, including the radiator and engine block. Compatibility: It should be compatible with the materials used in the engine, such as aluminum, copper, and steel, as well as rubber and plastic components in the cooling system. Longevity: An ideal coolant should have a reasonable lifespan without breaking down, losing its effectiveness, or depositing harmful contaminants in the system. Environmental Considerations: Coolants should meet environmental standards and regulations, and they should be disposed of responsibly. While refractive index can vary among different coolants, it is typically not a primary consideration for automotive engine coolant. Instead, focus on selecting a coolant that meets the performance and compatibility requirements outlined above to ensure the engine's cooling system operates effectively and efficiently.
There are 2 best coolants with proper values when mixed with distilled water 1) Castrol heavyduty 2) Bosch. Good and proper meg values and reliable. Go mechanic products are doubtful, mind it that ur radiator costs much more than these 2 coolants.. So go mechanic ise karne se pehle soch lo!
@@ranadeepacharya4178 Why Castrol blue coolant is not printing specification, how can we believe that it is a genuine Castrol product For my car tata altroz diesel comes with blue colour coolant, most of the company's not printing coolant specification
Golden Cruiser is the primary manufacturer of coolant. The best options for all weather conditions are either fully concentrated coolant or 50:50 antifreeze coolant, labeled RTU. For concentrated coolant, it's advised to dilute it with 50% distilled water before use. The 50:50 antifreeze coolant offers protection against freezing and boiling over, with a freezing point of around -37 degrees Celsius and a boiling point around 116 degrees Celsius Since 1988, I've been manufacturing coolant. Back then, conventional coolant was the only option available. Over time, companies have enhanced their quality standards, transitioning to OAT formulations due to vehicle manufacturers demands.However, the majority of companies tend to favor HOAT. While some opt for Propylene Glycol due to its eco-friendly nature, Ethylene Glycol is more commonly used, often in combination with OAT or HOAT formulations. Within the HOAT category, there are two distinct types. Now a days there are also new coolant in the market and that is Non Glycol coolant. It is non antifreeze coolant Thanks 🙏
@@psd4429 Okay. I am not sure on this. Maybe you are right also. But they have ethylene glycol based coolant which are good for cars having high pH values.
Ideal ph is between 8-9. Actually Propylene Glycol is more expensive then Ethylene Glycol. Sir I manufactured coolant in 1988 and got ISI mark. I gives my service to so many companies who successfully manufacture coolant and they also pack for big companies in their own brand
You are right that Ethylene Glycol based coolant is better due to its freezing and boiling point. But when your concentrated coolant having only 23% glycol and you mentioned use 1:3 in your direction for use. It means it is not good in cold weather. This 1:1 or 1:2 is good for pure / 100% concentrated coolant. Companies making fool to actual user
do the similar video with regarding your engine oil. compare yourself with mobil, shell, liqui molly, Valvoline, total and some oil from hp, bpcl and Indian oil
Sir in sare coolent ko gasa par ubal kar iska boiling temprechar Or in sare coolent ka freez karke batao tab pata chalega konsa coolent best he sir esa ek video bana do sir G.
Coolant ka boiling point daikhne k liye iska ek special boiling point apparatus aata hai, isko gas per boil ker k check nahi kiya ja sakta Jab apke coolant mai 10% glycol content ho toh iska matlab hai ki iska freezing point -5 and boiling point almost 103 degree Celsius hai.
Its totally dependent on the customer. Which brand they want to use in their car. Wurth is definitely good, but GoMechanic Smartcool gives you similar performance at lower cost.
@@gomechanicindia tbh, i didn't know any difference, my car is not an SUV, it's 10yr old wagon r and they guy quoted me 1200rs for 3ltr coolant, i got that i landed on a wrong place n moved.
Sir recently i have found one coolant Brand named TORRENT. Their MEG value is 65% with freezing point shown in refractometer as 40*f. Please compare their with the best product you feel in the market and make a comparison.
Hi Arjun, The MEG content should be less than 50% in a coolant. India is a tropical country, we don't experience extreme climates (-40 or +50 ). The MEG value of 65% is better suited for cold regions or deserts. Also, a high MEG content can form lumps and choke the radiator or cooling system.
You will not see immediate results after using liqui molly or Abro Diesel Injector Cleaner. It works internally to clean injector pipelines. Usually 1 bottle of 350ml per 60L is recommended
Interesting point to note is Gomechanic is experimenting with different brand coolant and Gomechanic brand coolant is getting first position.... Obviously this is a promotional video...
We are testing the MEG value on a scientific equipment, which cannot be rigged. You can yourself buy a refractometer and check the MEG value of these particular coolants.
Hi Neeraj The MEG meter can only identify glcycol when its less than 50%, while Castrol has got more than 50% of it. So, not eligible for the comparison.
Hi Shubham, The only types of coolant you should put in your Volkswagen are either G11 or G12 approved anti-phosphate, anti-amine, anti-phosphorous coolant.
Hi Amol, We used a digital refractometer to measure the MEG content, did exactly as the instructions says and didn't used diluted form of antifreeze. Can you please elaborate how those measures are wrong?
Hi, You can go ahead and buy the coolant form below given link. The suitable one will be of red colour. gomechanic.in/spares/coolant~ssc Do make sure that you mix the coolant and ditilled water in recommended quantity for beat results. Love, GoMechanic
Yes, you need to have a 50/50 mix of distilled water and GoMechanic coolant. You should check the colour of the coolant your car has and add the similar one.
Hi Vishal, There are many brands available as ready to mix solution. Please click on the following link to choose the best one. gomechanic.in/spares/coolant~ssc
Hi Chetan, GoMechanic does manufacture its own coolant. We will give a factory visit in the near future. Till than you can watch the brake pad and oil filter manufacturing units. - Brake Pad Manufacturing: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YhVZ06LPRZk.html - Oil Filter Manufacturing: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-79LP6M9Q-eg.html Love, GoMechanic
I use red coolant in my car so I ordered Gomachanic red coolant. But the colour of Gomachanic's red coolant is pinkish and not red or reddish. What should I do?
Hi, The red coolant may have a pinkish hue to it, but there isn't any issue. Just make sure you mix adequate amount of distilled water with the coolant. Please read the instructions carefully before topping up the coolant.
sir mera new 4 months old 2600km ,tata tigor car ka coolant blue colour se grey white kyu ho gaya hai kya problem hai. kya head gasket leakage problem hai pls reply
Sure, just check the color of the coolant in your Omni van and pour in the similar one. Do make sure to prepare a 50:50 mix of antifreeze and distilled water.
The Castrol coolant has a MEG value of more than 50 which can not be measured by refractometer. This value can can prove dangerous for your vehicle if not mixed with water properly.
of course you can use it on your polo! Just check the colour of the coolant and pour the identical one. Here is the link to buy one: gomechanic.in/spares/L4GWQ1707J-smart-cool-1l-green
@@gomechanicindia my friend used gomechanic coolant and his engine got seized he showed that to authorised maruti servicr centre and they said the coolant is cheap quality thats why it happend the engine got overheat
Coolant should be diluted with distilled water before filling it in the reservoir. When there is more coolant and water is less, any brand's product will cause problems for you, not just ours. However , you can forward your query yon escaltions@gomechanic.in
