Stains on the bottom of the garage, moisture under the hood or under the car clearly indicate a leak, the source of which must be identified. Sometimes this source is difficult to determine, especially if the engine has not been washed for a long time. The trace of the leak may be distorted by the air flow under the car, creating an incorrect idea of the location of the source of the leak.
Warning: Most automotive oils and fluids are poisonous. If they come into contact with your skin, wash them off immediately, and if they come into contact with your clothing, change your clothes.
