MAINTENANCE TIPS


• With today's computerized engine systems, maintaining your vehicle's exhaust and emissions system is best left to a professional technician.

 

• When replacing oxygen sensors it is important to use GM OE parts. Parts that do not meet GM OE service specifications, such as element type or cover design, can be detrimental to emission controls. Increased nitrogen dioxide emissions, higher exhaust gas temperature, misfires or loss of engine power can result from using noncompliant sensors. This can also lead to engine component failure caused by overheating of the catalytic converter.

 

• It is critical that you have the right part with the right wire length for your vehicle. Excess wire can be exposed to extreme heat and abrasions that can lead to premature wire failure. ACDelco Oxygen (O2) Sensors use the correct sensor components that GM has validated to engine specific applications.
