Do not bend or damage the radiator fins.
When cleaning the radiator without removing it from the vehicle, remove all adjacent parts: cooling fan, radiator shroud and horns. Wrap the harness and connectors with protective tape to prevent water from entering.
Pour the radiator core from the back side with water from a hose vertically downwards.
Again pour water over the entire surface of the radiator core (once per minute).
Stop watering if dirty water no longer drains from the radiator.
Pic. 2.214. Radiator purge: 1 - pump; 2 - radiator cap
Blow the radiator core with air from the reverse side vertically down (pic. 2.214).
Supply compressed air with a pressure below 113-142 kPa (1.1–1.4 kg/cm2) and at a distance of more than 30 cm.
Blow air over the entire surface of the radiator core again (once per minute), until the water stops flowing.
