Better known as a smog pump. Check with state inspections if they require emision testing. As far as if it will hurt the motor, No it will not, an the increase in horse power is really not significant.Most problems are with the gulp valve or diverter valve which causes back fire when throttling back. Air pump failure is due to carbon siezure from check valves on exaust.
It should be self-purging, unless there is some sort of leak.
The AIR pump, pumps clean air into the burnt exhaust gasses that is in the exhaust system/pipes and cleans it up before it exits the tail pipe.
take the line off of it and see if it is pumping air
Enough. Get it dyno'd.
remove air inlet, then auxiliary battery, then battery tray. the pump is located under and attached to the reservoir
EGR valve, purge valve, And maybe a air pump.
You have to remove the pulley first and you need a power steering pulley puller to do it. You can get one from Napa for usually about $40. There are bolts behind the pulley that hold the pump to the mounting bracket.
No you do not.
If the air vents of the Chevy trailblazer 2004 are not blowing air, have the fuel pump checked.
Remove reservoir cap and pump the clutch pedal until air bubbles rise and pedal feels firm.
Air in the system. Bleed the system. Defective thermostat, clogged radiator, defective cooling fan or fan clutch.
this is a very time consuming job! it involves removing the water pump to get to it. disconnect the battery negative terminal, set aside upper air baffle and air filter box, remove appropriate belts, remove fan blade, remove water pump, now you are to the distributor cap. good luck
