This unique tool has been developed to remove and install the water pump on DADILLAC NORTHSTAR 4.6 LITER V-8 engines from 1993 and later also oldsmobile AURORA 4.0 LITER V-8 engines 1995 and later.
Many of the sockets presently available on the market are fragile in nature due to the confined area around the water pump impeller and can not use for impact wrench.
