The radiator of the car engine is removed for cleaning and flushing it or for replacement if a leak is detected
A car radiator with a horizontal fluid flow, with a tubular-ribbon aluminum core and plastic tanks. There is a drain tap at the bottom of the left radiator tank.
We prepare the car for the job, install it on a lift or an observation ditch

Rinse the radiator from the outside with a jet of water and dry it. If cracks have formed on the plastic radiator tanks, replace the radiator.
Check the tightness of the radiator, for which shut off its pipes, bring air to it at a pressure of 0.1 MPa and lower it into a container with water for at least 30 seconds. The leakiness of the radiator is determined by the outgoing air bubbles.
If the radiator does not fit completely into the container, check it sequentially from all sides.
Install the radiator and other parts of the engine cooling system in the reverse order of removal.
In order to further eliminate the possibility of leakage of coolant, lubricate the radiator pipes with a thin layer of silicone sealant before installing the hoses.
Fill in the coolant and remove the air plugs from the cooling system
