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.

Buick Enclave Oxygen Sensor

The Oxygen Sensor in Buick Enclave cars is important as it tracks the air/fuel relation in the engine exhaust to ensure perfect functioning and minimum pollution. Thus, contrasting the level of oxygen in the exhaust to that of fresh air, the sensor produces a voltage signal to the engine control computer regarding the mixture quality: rich or lean. This feedback enables the computer to vary the fuel injector pulse width in a manner to get maximum conversion efficiency of the catalytic converter and at the same time reducing emissions to a minimum. A Buick Enclave automobile requires at least two oxygen sensors, one before the catalytic converter and the other after it; the pre-converter sensor is especially this feedback source. The sensor works at high temperature and may degrade with time mainly due to contamination. Air/fuel ratio sensors that are advanced than oxygen sensors, could be available in some newer automobiles to provide improved measurement of air/fuel ratio.

Each OEM Buick Enclave 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.
