Cleaning drainage holes Opel Astra H

During operation, moisture accumulates in the cavities of the thresholds, doors and trunk lid, causing corrosion. Drainage holes are used to remove moisture, located below the thresholds, doors and in the trunk lid (tailgate). They are constantly clogged with dirt, so clean them at every maintenance (every 20,000 km of run). When operating the Opel Astra on country roads, carry out this operation more often.

Useful advice

Clean the drain holes before washing the car.

You will need a screwdriver or a thin wooden stick.

1. Clean the drain holes in the front and rear doors...

2. ...and also in the tailgate.

Note

Drainage holes in the floor thresholds are closed with rubber plugs. Periodically remove them to drain condensate and water that accidentally got into the cavities of the thresholds.
