Growing up, we saw those having or driving cars putting or asking us to help them pour water into the radiator of their cars' engines. The water is meant to prevent the cars' engines from overheating, which could eventually lead to the engines knocking or spoiling. Unfortunately, we see many vehicles by the roadside overheating, and their drivers or owners will have to wait for the cars to cool down, or they'll have to tow them to a nearby mechanic workshop. And we see many car owners and drivers frequently repairing or replacing their cars' engines, not knowing that it was a result of them using water.

But as we grew up, we understood that water is not meant to be poured into the engine's radiators but that coolant, which comes in different colors, should be used. Coolant has various additives which help to prevent the engine of cars from overheating and rusting. Recently, I diagnosed a vehicle that suddenly brought a check engine warning light on its dashboard, and the machine reported that the liquid in the engine wasn't giving the right temperature, and it could cause the car's engine to overheat. After getting the report from the machine, I checked the radiator and found water instead of coolant inside it. Next, I ordered 5 liters of original coolant, which cost me N20,000 or 28$ equivalent, even when some spare parts sellers asked me to buy that of N4,000 or 5$ equivalent. But because I know the importance and functions of coolant in a car's engine, I decided to buy the original one.

I drained all the water in the engine's radiator and replaced the engine's temperature sensor, which the water had already spoilt, after which I poured the coolant into the radiator. After I did that, the check engine warning light never returned after several days. With what I did, I was able to save the engine of the car from getting bad or knocking, which would have cost me a lot more. With this, you should be able to know that it is dangerous to use water in the radiator of your car's engine, and you should instead use coolant. Please note that you should use recommended coolant with the right color for your vehicle by checking its manual, searching online, asking people, or, better still, your mechanic.

One last question, do I need to drain the water out from my radiator before pouring this coolant into the coolant reservoir or leave the water already inside the radiator?
