Model Years Affected: 2000, 2001, 2002, 2003, 2004

Average Mileage: 106,631 mi (10,000 mi - 190,000 mi)


Water may be drawn into the secondary air injection (AIR) pump causing the pump to fail and the Check Engine Light to illuminate. Our technicians tell us there is a kit available from General Motors to relocate the air intake for the pump which should prevent future damage from water intrusion.

    The dealer told me secondaryair pump was bad. I found the air intake hose disconnected both ends. I installed new pump and intake cleared the code and the next cold start the light came back on. Now what?

    Water has filled the air pump and it has been replaced 3 times. It now has filled for the 4th time and no one seems to be able to tell me where the water is coming from.The pumps are Delco pumps I'm ready to trade the car.

    Technical Service Bulletin 02-06-04-024G covers this problem. I was charged $249 for the pump and $250 for the labor. I will be returning to the dealership because it appears I was overcharged for labor. According to the TSB, the labor rate should be 0.9 hrs, which wouldn't approach the $250 I was charged.

    The bottom of the TSB states:

    Labor Operation

    Secondary AIR injection Pump and Hose Assembly - Replacement

    Labor Time
    0.9 hr*
    *This is a unique labor operation for bulletin use only. It will not be published in the Labor Time Guide.
