5/3/2023 0 Comments Honda coolant![]() This is not to say that Ethylene Glycol isn’t used in today’s cooling systems. Thus, started the hunt for a liquid which would further last a lot longer. An electrically conductive liquid when in contact with the iron present in the engine block would be the perfect recipe for rust formation The more lethal property of Ethylene Glycol was that its disintegration would exponentially increase its electrical conductivity. ğirstly, its chemical composition meant it would disintegrate and lose its properties, thus requiring a change every 2-3 years Ethylene Glycol however brought about two other minor headaches: This means the fundamental issues of early freezing (due to inherent properties of water) and early boiling (due to properties of alcohol) stood solved. Ethylene glycol-based coolant is called “Inorganic Acid Technology based coolant” because it contains silicates and phosphates in order to comply with the metal parts in a cooling system.Īn Ethylene Glycol and water mixture (in a 60:40 ratio) would freeze at - 45 degrees Celsius (thus beating even alcohol in this regard) and boil at well over 100 degrees Celsius. The answer to this predicament was (and still in many cases) is ethylene glycol. There was a need for a liquid that would offer the depression in freezing point normal alcohol such as ethanol would, yet not boil over early like the former did when it formed a mixture with water. Inorganic Acid Technology (Ethylene Glycol) Unfortunately, the boiling point of alcohol was much lower than water, which would mean the resulting mixture would also boil very early (around 80 degrees Celsius), needing frequent top-ups. Alcohol formed a mixture with water which would lead to a “depression” in freezing point, thereby preventing freezing. In order to overcome the former, alcohol was added to water and used as a coolant. This would also impact the heat transfer (by forming oxides) and cause issues in both the radiator and engine block. This rust would eventually choke the radiator over time too. Secondly, water would react with the iron present in the engine block and form rust. ![]() This means it would freeze and block cooling system pipes and radiators in the winters. ğirstly, water has a comparatively high freezing point of 0 degrees Celsius. There were two downsides or shortcoming however: The high specific heat capacity ensured it could transfer a large amount of heat easily from the engine block to the radiator. Water with its high specific heat capacity (which basically means it needs a lot of heat in comparison to other liquids in order to raise its temperature by a specific amount) was perfect for car radiators in theory. In the olden days, the word “coolant” simply implied “water”. It’s a fluid that is second to only engine oil in an internal combustion engine, yet is ignored most of the times. A very simple yet crucial component in the era of modern (comparatively) high compression ratio engines. Thanks to him for the expert inputs!Ĭoolant. My fathers city aspire 1.5 prosmatec is 85,000 Km driven in 2 years and the coolant level is still the same as when we bought the brand new car.This thread has been jointly compiled with bhpian Vigsom. The coolant level should be checked when the car is warm because coolant expands and if you pour coolant to the brim of the reservoir tank and when the car gets warm the coolant will overflow from the reservoir tank, so check the levels when warm, if the coolant level is decreasing there is some leak or major problem with the water body of the cooling system of car.Ĭoolant level of a new car SHOULD NEVER DECREASE even a single drop. He said ke ye kam hota hai aap pani dal den uper say thora.Kindly advise is it normal coolant level to become low for a new car?Can I top it up with plain water in emergency?Which coolant is already put in new City? Green or Blue (Type 1 or Type 2 Honda coolant)Can i top it up with some other brand coolant like Zic as Honda coolant is very expensive? I heard if there are different types of coolant it can be dangerous.Thanks I went to Honda canal bank, the mechanic opened the cap of radiator and the level in bottle gone up to almost the middle. Dear All,I bought Honda city 3 weeks back and today in morning I checked the coolant level it was just slightly above Min level.
