Every car engine needs coolant to function properly. It protects the engine from overheating and keeps the internal parts away from rust and damage. But many times people make small mistakes while changing the coolant, which can damage the engine. If you want to keep your car healthy for a long time, then it is very important to avoid these five mistakes.
using the wrong coolant
The first thing you need to know is that there is a different type of coolant for every car. If you do not choose the right coolant as per your car model, the dirt and rust accumulated inside the engine may increase. Therefore, always buy coolant after following the manual guidelines of the car.
Not completely draining out old coolant
Many people just take out some of the old coolant and add new coolant. By doing this the new coolant does not work properly and the engine does not remain completely cool. Therefore, there is a need to completely drain out the old coolant and fill in new coolant.
overfilling or underfilling coolant
If coolant is overfilled, pressure in the engine may increase and leakage problems may occur. However, if the coolant is less, the engine will not cool down properly and the risk of overheating will increase. Therefore always fill the coolant as per the level mentioned in the manual.
Changing coolant when engine is hot
Apart from this, changing the coolant also becomes very important when the engine gets hot. Many people start changing the coolant without cooling the engine. Doing so can be dangerous as hot coolant may spill out and cause injury. Therefore, always start work only after the engine has completely cooled down.
air freeing the system
If there is air left in the coolant system, the coolant does not reach the entire engine properly and the engine starts heating up. After filling the coolant, it is always important to free the system of air.
