How to Flush a Clogged Radiator
Flushing the clogged radiator may sound hard, but it is not true at all. You can follow the given instructions to flush your clogged radiators.
Here are the things that you need:
- A radiator flush
- Running Water
- Radiator Fluid
- Garden Hose
How to detect a clogged radiator
The first thing you require to decide is whether you need a clogged radiator or not. If the radiator is clogged, then the coolant system of the car will not work correctly, and the engine will overheat. The main task of a car’s radiator is to protect the engine from overheating. If the engine overheats, then it must be a sign of something that is going wrong around the engine. Generally, the internal contaminants, dirt, and debris cause clogged radiators.
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
During the flushing procedure, there will be dirt and debris coming out from the engine. Putting a bucket under the radiator will help to store the junks so that you can easily discharge them later. 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
Make sure that you have selected the right flush solution depending on your car’s engine. There may be other ways of cleaning a radiator, but using the radiator flush will give you the best results. It will remove all the dirt, debris, and rust immediately from the radiator. It can also assist in lengthening the water pump life as it also lubricates the system. Then open the radiator cap and then put the flush solution on the radiator from the bottle.
Flush out the solution after 10 minutes
Let the cleaning solution sit idle in the radiator for ten minutes. In the meantime, the solution will travel through the tubes of the radiator for the cleaning. Now disconnect the hose of the radiator from the system. After that, you can use a garden water hose, which is connected to a water source for the cleaning procedure. Connect the radiator hose with the water hose and turn on the water supply. You will see the debris coming out through the pipe.
