In a 2011 Chevy Equinox, you'll locate the PCV valve at the back of the engine by the valve cover, near the firewall in the engine compartment. This valve is important for managing emissions from your engine. Basically, the PCV valve helps redirect gases from the crankcase back into the engine, where they're burned along with other exhaust fumes. This process prevents a lot of pollution that would occur if the gases were simply released into the air. It's an effective way to minimize and regulate pollution from your vehicle's engine.
