Question about 1989 Chevrolet Suburban
Went in to get emissions test the other day, and the test technician said I had no air pump (aka AIS, AIR, or smog pump) on my 1989 Chevy Suburban 1500 5.7 liter. Is it possible I have a vehicle with a mid-year change that doesn't have the air pump.
BTW: I went to another test station and they passed my Suburban with no problems and the history for the vehicle's AIS system checks is "N/A" for all previous years of emissions testing. I've owned the vehicle since it was new...
Your vehicle came with a smog pump. It may have seized up (probably breaking the fan belt) and my have simply been removed by a mechanic at an earlier time. It is located below the alternator on your vehicle.
If there is no pump but a bracket to hold it, it has definitely been removed. Vehicles will often pass a state smog test without the pump. It only works during engine decelleration (when you lift your foot off of the gas pedal)
