Where is the Cabin Air Filter Located in the Cadillac ATSL?

[RubyLynn]

The cabin air filter in the Cadillac ATSL is located under the glove compartment on the passenger side. Below are some precautions for replacing the cabin air filter: 1. During installation, whether the air filter is connected to the engine intake pipe via a flange, rubber hose, or direct connection, it must be tightly secured to prevent air leakage. Rubber gaskets must be installed on both ends of the filter. The wing nuts securing the air filter cover should not be over-tightened, as this may crush the paper filter element. 2. During maintenance, the paper filter element must never be cleaned with oil, as this will render it ineffective and may lead to engine runaway accidents. 3. For cleaning, only use vibration methods, soft brush cleaning (following the folds of the filter), or compressed air reverse blowing to remove dust and dirt from the surface of the paper filter element. For the coarse filter section, promptly remove accumulated dust from the collection area, blades, and cyclone tubes.
