Timing Belt Adjuster Water Pump Wrench AM-J-42492-A
Applications: 1.6L engines in 2004-current Chevrolet Aveo excluding 2009 with variable timing engine and 1999-2002 Daewoo Lanos. Also works on the Chevrolet Optra in markets outside the US.
41mm specialty automotive tool used to adjust the timing belt tension on a Daewoo Lanos by turning the ecentric water pump. This can be a very difficult task on this car without the specialty tool, due to the shape of the water pump which allows little access to the wrench flats.
