The formation of damaging particles in the car’s cooling system cannot be absolutely avoided. After some time, deposits or rust can accumulate which can affect the operation of the radiator and the entire cooling system. Therefore, it is necessary to occasionally drain out the coolant so as to remove the unwanted particles blocking up the system.
The ideal appearance of the coolant is somewhat thick with a yellowish green color. For vehicles using a long-lasting coolant, it appears as orange. When the color of the coolant in the radiator becomes brown along with floating fragments of rust, then the coolant must be removed.
To do this job, several steps should be considered:
1. You must first ensure that the ignition is turned off. It is very risky to do the task when the engine is still hot, thus, let the part cool for a while.
2. After the engine has been cooled enough, you can now remove the cap of the radiator.
3. Put a large container, like 2 gallon bucket, underneath the auto radiator. Then, remove the plug. The container will be used to catch the build up fluid.
4. If the fluid has already finished draining, place the plug back in its position.
5. The process can be repeated if you want to drain more coolant in the car engine.
Aside from draining, flushing can also be done if you want to thoroughly clean the cooling system. This would likewise remove rust particles or sediments. You need to have a radiator cleaning product to work on this task. Next is to secure the drain plugs. Together with water, pour the cleaning product into the auto radiator. There are instructions included in the package which involves allowing the heater high for a particular time. As the vehicle engine cools, the fluid in the radiator can now be drained. Then, refill with water. By this process, the cooling system is totally flushed out.
