1979 403 Water Pump Part number
« on: April 03, 2019, 05:14:17 PM »
Still looking for the correct part number for a 1979 trans am with a 403 olds motor.  I have been looking on ebay but only finding water pumps that will work.  I am trying to replace my water pump with the correct 1979 part.  Any help would be greatly appreciated.

You want #412265 , otherwise easy to spot by the large 4. This was the Air-Con version used on earlier years but standard on 305/403 Olds in Firebird regardless of AC or not, 6" from mounting face to mounting face.
