How to replace oxygen sensors in a Buick Enclave,Chevrolet Traverse and GMC Acadia?

Oxygen sensors in the exhaust manifold can be hard to loosen when cold. To avoid damage, run the engine briefly before shutting it off, but avoid burns. When servicing, handle the sensor carefully, avoid damaging the attached pigtail and connector, and keep contaminants away. Don't use cleaning solvents and ensure the silicone boot is correctly positioned. To replace, note there are four sensors; one in each manifold and one after each catalytic converter. For upstream sensors, remove the engine cover, disconnect the connector, remove the sensor, apply anti-seize compound to threads if reusing, and install securely. For downstream sensors, raise the vehicle, disconnect the sensor, unscrew it, apply anti-seize if reusing, and install securely.

GMC Acadia Oxygen Sensor

The Oxygen Sensor in GMC Acadia vehicles enables monitoring of the air/fuel mixture largely in the engine exhaust to improve on its performance and also to minimize on its emissions. The sensor responds to the signals representing the amount of unburned oxygen in the exhaust gases and sends feedback signals to the engine control computer an this way it keeps the air to fuel consumption ration in check. Oxygen sensor usually consist of a sensing element of zirconium dioxide with platinum coating an internal construction of ceramic and steel. These sensors have high-temperature operation, and often a heating coil for better response time. Modern GMC Acadia produced vehicle models are usually fitted with a minimum of 2 oxygen sensors, one of which is before and after the catalytic converter the feedback necessary for the fuel control. The upstream sensor is the only feedback source for the computer which the downstream sensor checks on the catalytic converter effectiveness. The undesirable effects of deterioration of oxygen sensor include increased emissions, decreased fuel efficiency thus requiring maintenance and replacement. Some newer vehicles may have air/fuel ratio sensors instead of, or in addition to, the oxygen sensors in the exhaust: these sensors offer a greater range of measurement capability.

Each OEM GMC Acadia Oxygen Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
