The first thing you require to decide is whether you need a clogged radiator or not.

The signs of a clogged radiator also include a risen inside temperature, water pump damage, leaky coolant, strange fluid discoloration, damaged head gasket, low coolant, unusual fluid discoloration, etc.
Let the engine to be cooled:
The engine of the vehicle must be cool before you start working. The cooling system runs the coolant to keep the engine cool. When the engine is on, the coolant goes all around the pipe before coming back to the cooling system again. So, make sure that you had given enough time to the engine before you started the cleaning procedure. It is crucial as things can go wrong if the engine is not cooled correctly.
Put a bucket under the radiator:

The bucket will work like a basin during the procedure. Make sure that you are putting the basket under the radiator.
Pour the flush solution:
