Car smudges and stains

Stains on the floor 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 leak trail can be distorted by airflow under the machine, giving a misleading impression of the location of the leak.

Warning: Most automotive oils and fluids are poisonous. In case of contact with skin, wash off immediately, and in case of contact with clothing, change clothes.

Advice

The smell of a leak can tell you what is leaking. Some liquids have a specific color. It's a good idea to wash your car thoroughly and place a clean sheet of paper under it overnight to determine where the leak is.

Keep in mind that some leaks can only occur when the engine is running.
