Top Smog Pump Questions

  • Why does the smog pump I installed make noise?

    Due to the use of new parts on these units, there will be a certain amount of time needed for break-in. We suggest that a 500 mile run-in be allowed and the noise will go away.
  • My vehicle is not running right and it just failed for emissions. Is the smog pump defective?

    This is not necessarily the fault of the pump. A defective, worn belt or defective valves and or check valves could be the problem. These should be checked and replaced before the pump.
