This GM AC Delco Big Block water pump,.... not limited to the listing below.

Runs standard rotation and built to be optionally  fitted with a Clutch or Thermal Fan.  Note the 3 mount holes on the LHS and the short neck of the main shaft.

Assembled in the USA from US and Imported Parts.

Every belt driven water pump has a weep hole that might leak a little in the beginning. Some seepage from the weep hole is normal during the break-in period (about 10 minutes), and does not indicate a defect.
