Camshaft Locking Tools
3088-15 (Yellow) and 3088-16 (Blue)
NOTE:
These tools are colour-coded for
engine use identification.
Prior to model year 1999 the 1.8
16V EcoTec engine was based on the 2.0 16V
and uses Locking Tool 3088-15 (Yellow). From
model year 1999 the 1.8 16V is based on the
1.6 16V and uses Locking Tool 3088-16
(Blue).
These tools are inserted between the two
camshaft sprockets, locating firmly into the
gear teeth of the sprockets. This action locks
the sprockets to prevent them from turning
out of their timed position, when timing belt is
removed. Camshaft timing marks must align
before inserting locking tool.
NOTE:
OPEL camshaft timing marks vary
in position according to the model
of engine. For example, they can be
at the top (3 A), or centered (3 B). Check
service information carefully.
