How to replace the Air Inject Check Valve on GMC Canyon?

The replacement of the Secondary Air Injection Check Valve requires starting with hood opening followed by air cleaner outlet duct removal. First disconnect the secondary air injection (AIR) pump outlet hose quick connect fitting from the air check valve after you detach the engine wiring harness electrical connector from it. Remove the air check valve studs first before you extract the air check valve installation together with its gasket that goes into disposal. Insert a new air check valve gasket between the engine and the valve before setting the air check valve in its carrying position on the engine. Place air check valve studs on their proper positions then apply torque to 25 nm (18 lb ft). Connect the engine wiring harness connector to the air check valve while installing the outlet hose quick connect fitting to the valve. After reinstalling the air cleaner outlet duct the hood should be closed.

How to replace the secondary air inject check valve on GMC Envoy?

The replacement process of the secondary air injection solenoid valve begins with removing the air cleaner outlet resonator followed by disconnecting electrical connectors from the secondary air injection (AIR) reaction solenoid valve and the AIR pump air outlet pipe from the AIR solenoid valve. Afterward remove the nut that holds the transmission fluid level indicator tube to the AIR solenoid valve and pull out the indicator tube from the AIR solenoid valve stud. Remove the gasket and both 2 AIR solenoid valve studs and the AIR solenoid valve from the engine compartment. Position the AIR solenoid valve with a gasket on the engine while installing two AIR solenoid valve studs with proper torque to 25 N.m (18 lb ft). Connect the transmission fluid level indicator tube to the AIR solenoid valve stud while you secure it with nut before tightening it to 10 N.m (89 lb in). The AIR pump air outlet pipe needs to be connected with the electrical connector to the solenoid valve while you reinstall the air cleaner outlet resonator.

GMC Air Inject Check Valve reduces the emission through the introduction of clean air into hot exhaust streams. GMC is founded on over a century of trucks and SUV construction that values brute power and everyday comfort. Strong frame with torque-laden engines are applied when towing on weekends and making weekly errands. The potholes are suppressed and payload remains constant. This has maintained cabin quietness due to layered insulations and narrows between panels. Hitch guidance and surround vision cameras make hooking up trailers easier. MultiPro is a flipping, folding, and clamping tailgate. The prototypes are beaten with testing cycles until only stout parts remain. GMC supports that process with warranty as long as it claims it is durable. Air Inject Check Valve is opened at the cold start to inject more oxygen into the exhaust and burn the remaining fuel but closes when sensors show that normal flow is established to avoid the scalding of the pump by hot gases. The section refines the hydrocarbons to ensure that the engines fail hard emissions tests and that they do not get red lights. Internal corrosion-resistant valve holds spring tension during savage heat cycles. The flange mount is simple, and the cost of replacement is low and fast to most drivers. There is also a new Air Inject Check Valve that induces smooth idle and rough cold start.
