PLEASE study these instructions carefully before beginning this installation. Most installations can be accomplished with common tools and
procedures. However, you should be familiar with and comfortable working on your vehicle. If you do not feel comfortable performing this installation,
it is recommended to have the installation completed by a qualified mechanic. If you have any questions, please call our Technical Hotline at:
1-800-416-8628, 7:00 am - 5:00 pm, Pacific Standard Time, Monday through Friday.
IMPORTANT NOTE: Proper installation is the responsibility of the installer. Improper installation
will void your warranty and may result in poor performance and engine or vehicle damage.
DESCRIPTION: The Edelbrock aluminum water pump is a heavy duty water pump for both street and racing applications. The pump is externally the
same as original equipment pumps to provide compatibility with all accessories and pulleys. It offers weight savings along with increased durability
and cooling potential. An additional feature is the threaded tab for a cam stop that can be used to pre-load the timing chain cover and limit camshaft
forward movement. NOTE: These pumps MUST BE USED WITH REVERSE ROTATION SERPENTINE BELT PULLEYS.
#8815 is a reverse rotation water pump for 1984-92 Corvettes with serpentine drive belt. Not for LT-1 Corvettes. Polished Aluminum Water
Pump #8825 fits the same applications as #8815.
#8881 is a reverse rotation water pump for 1987-93 passenger cars and light duty trucks with serpentine drive belt. Not for Corvettes.
Permastar Coated Aluminum Water Pump #88812, EnduraShine Coated Aluminum Water Pump #88814, and Polished Aluminum Water Pump
#8891 fit the same applications as #8881.
#8882 is a short leg pump for 1955-'68 passenger cars, light duty trucks, and 1969-'70 Corvettes with AFTERMARKET serpentine belt pulleys
(reverse rotation). This pump is ideal for street rods with aftermarket serpentine belt pulleys. Polished Aluminum Water Pump #8892 fits the
same applications as #8882.
INSTALLATION: Installation is the same as for original equipment water pumps. Consult service manual for specific procedures, if necessary.
CAUTION: Be sure that fan bolts don't protrude through the hub so far that they hit the water pump housing.
NOTE: Removal of backing plate is not recommended, as there are no user serviceable parts in the water pump. If backing plate is removed,
use conventional gasket sealer (not RTV silicone) on gasket.
SPECIAL NOTES: Check closely for any interference with drive belts; some filing for clearance may be necessary with some applications.

ACCESSORIES FOR #8882/#8892: Use #8830 Spacer Kit for short style pumps to clear competition camshaft gear drives and belt drives. Kit
includes 1/2" thick water pump and crank pulley spacers.
Incorrect alignment or an unbalanced condition puts excessive strain on the pump's shaft and/or bearing and will result in early failure of the
shaft and/or bearing. The balance of the assembly depends primarily upon the concentricity of the fan clutch and spacers with the pump shaft.
Concentricity is not assured when universal type clutches or spacers are used. Universal fan clutches and spacers have a 3/4" pilot hole, so an
adapter must be used when installing a water pump with a 5/8" shaft. This adapter bushing is supplied with the unit. These adapter bushings
add to the machine tolerances of the assembly, so special care must be taken to maintain concentricity with the shaft and the fan clutch.
Failure to do so will void warranty. The use of aftermarket (non-OEM) fan spacers are not recommended and will void the warranty of
the water pump.
