Title: great pump!
Product review: After orig. a.i.r pump or smog pump failed on 2001 chevy s10 I looked everywere for this pump junk yards wanted $100 or more. At other sites this pump went for $200 . I purchased this ACDelco cheaper than even at the junk yard! If you change out your pump because of water infultration do not forget to also change out the Exhaust check Valve, Shut of Valve , and Egr Vacuum Solenoid because the water from exhaust would most likely damaged these parts as I can vouch for.
