Engine Oil vs Coolant: What's the Difference and Why Both Matter
Have you ever opened your car hood to check the fluids in your engine and wondered which fluid does what? Well, we have. And it turns out many people get confused between two important fluids used in car engines – engine oil and coolant. However, these fluids serve different functions, and you can't drive smoothly without either one, whether you have a hatchback or an SUV. Here is everything you need to know.
What Does Engine Oil Do?
Engine oil is essentially used for the process of lubrication in an automobile. It is the fluid that lubricates all the internal parts of your engine, allowing them to move freely inside the engine compartment.
Without the use of engine oil, friction would occur between all the metal parts inside the engine, causing your vehicle to malfunction. Apart from acting as a lubricant, engine oil also helps in cleaning the engine by trapping all kinds of dirt particles that may cause harm to the engine components.
In today's time, there are more chances that you will be using synthetic engine oil or fully synthetic engine oil rather than the mineral one because of the improved performance characteristics of the former.
Oils used in cars come with certain codes on them, like 5w30 engine oil 10W-300 engine oil, 15w40 engine oil, and 0w20 engine oil, among others. The numbers written after the letters tell us about the viscosity,y or the thickness, ss of the oil and in Indian conditi 5W-305w30 fully synthetic oil is usually the best choice.
Timely engine oil flush and replacement will greatly help in prolonging the life of the engine. Failure to conduct such basic maintenance measures often becomes a reason behind expensive repair bills for many Indian car owners.
What Does Coolant Do?
While the engine oil acts as the lubricant in an automobile, coolant is used for temperature control in an engine. When the engine runs, it generates an enormous amount of heat, and if left unchecked, that heat might warp any of the metal parts of the engine, causing it to malfunction.
As the coolant is circulated through the various parts of the cooling system,m including the radiator and cylinder jackets, it absorbs all the heat generated by the running engine, taking it back to the radiator,r from where the heat is released into the atmosphere. It is the same process of liquid cooling that happens in high-performance motorcycle engines as well.
Most of the coolants are found in bright colours like green, pink, and orange,e and they are known as radiator coolant. Pink coolant and green coolant are quite commonly found in Indian cars, and you should not mix different coolant types in order to avoid damage to the cooling system. Getting a radiator flush done once in a couple of years is a must,t apart from regular checking of coolant levels.
None of the fluids can be used in place of the other. Running out of engine oil will lead to friction damage, whereas running out of coolant will result in overheating – both of them being equally disastrous for the engine.
How Maintenance is Important
Many Indian car owners only consider the issue of engine oil price or coolant price once there is some kind of problem. However, maintenance costs are always lower than the repair cost. It will only require you to regularly check the levels of oil and coolant in your car, along with paying attention to the warning lights on your dashboard,oard and then going to a trusted service centre.
If you search for something like engine oil near me or car oil price before getting your engine oil changed, it will only be a positive thing. This is applicable even if you are considering selling your car in the future, as you will easily get a better resale value for a well-maintained engine with proper oil and coolant.
