Where is the secondary air injector located on 2005 Buick Lacrosse?

Answer 1

The secondary air injector on a 2005 Buick Lacrosse is typically located near the engine, often mounted to the intake manifold or near the exhaust manifold. It is part of the emissions control system, designed to inject air into the exhaust stream to help reduce emissions during cold starts. To access it, you may need to remove components like the engine cover or other parts obstructing the view. Always consult the vehicle's service manual for precise location and removal instructions.
