If the car is used on dusty and dirty roads, as well as during the "poplar fluff" period, check the cleanliness of the radiator more often (visually through the cracks in the cladding). Be sure to clean clogged radiator cells, otherwise the engine will overheat.
Open the hood and remove the six screws securing the radiator grille (three screws are shown, the rest are located symmetrically on the other side of the lining).

Remove the radiator grille by lifting it upwards.

Clean the radiator honeycomb thoroughly with a brush. Blow the radiator honeycomb from the engine compartment with compressed air from a compressor or pump.

When installing the radiator grille in place, use a screwdriver to insert the fasteners behind the body flanging.
