3The tensioner assembly, fitted to the
underside of the front seat, is maintenance
free and, once triggered, must be replaced as
a complete unit.
4Due to the specialist safety related nature
of the seat belt tensioner system, replacement
must be entrusted to a suitably equipped
Vauxhall dealer.

Removal
1Remove the single securing screw from the
front edge of the outer seat rail trim, release
the rear retaining lug and remove the trim
rearwards.
2Unclip the trim from the rear edge of the
inner seat rail.3Locate the plastic safety fork for the seat
belt tensioner, which is usually taped to the
outside of the tensioner spring cylinder.
4Insert the fork into the aperture provided at
the rear of the spring cylinder, ensuring that
the fork engages securely (see illustration).
5Remove the four bolts which secure the
seat rails to the floor, then withdraw the seat
complete with rails (see illustration). Recover
the washers and backplates.
6Seek the advice of a Vauxhall dealer if there
is any doubt about the condition of the seat
belt tensioner assembly.
Refitting
7Refitting is a reversal of removal. Note that
the manufacturers recommend the use of new
bolts to secure the seat rails to the floor.
Tighten the bolts to the specified torque
wrench settings (see Specifications) in the
order - rear inner, front inner, rear outer, front
outer.

Warning: The seat belt
tensioners fitted to the front
seat assemblies may cause
injury if triggered inadvertently.
Before carrying out any work on the front
seats, a safety fork must be inserted into
the seat belt tensioner cylinder, to prevent
the possibility of the tensioner being
triggered (see paragraphs 7 and 8 below).
Seats should always be transported and
installed with the safety fork in place. If a
seat is to be disposed of, the tensioner
must be triggered before the seat is
removed from the vehicle, by inserting the
safety fork, and striking the tensioner
cylinder sharply with a hammer. If the
tensioner has been triggered due to a
sudden impact or accident, the unit must
be renewed, as it cannot be reset. Due to
safety considerations, tensioner renewal
should be entrusted to a Vauxhall dealer.
