21.7a Turn the drivebelt tensioner using a
spanner on the pulley centre bolt
(arrowed) ..•
17 Lubricate the threads of the retaining ring
with a little diesel fuel then screw the ring
onto the housing. Reposition the housing
horizontally in the vice as before, and tighten
the retaining ring to the specified torque using
the special tool or alternative.
18 Insert the filter assembly into the crash
box, making sure that the retaining clip
engages. Reconnect the fuel hoses and the
wiring connectors.
19 Refit the crash box cover and tighten the
retaining bolts securely. Clip the fuel hoses
into the cover.
20 Bleed the fuel system as described
in Chapter 48 and check all disturbed
components to ensure that there are no leaks
(of air or fuel) when the engine is restarted.
21 Refit the windscreen cowl panel as
described in Chapter 11.
22 On completion, safely dispose of the
drained fuel.
Note: The manufacturers recommend that the
tensioner roller is checked and if necessary
renewed at the same time as the drivebelt.
Checking
1 Due to their function and material make-up,
drivebelts are prone to failure after a long
period of time and should therefore be
inspected regularly.
2 Apply the handbrake, then jack up the front
of the vehicle and support it on axle stands
(see Jacking and vehicle support). Remove
the right-hand front roadwheel and the wheel
arch liner cover for access to the right-hand
side of the engine.
3 With the engine stopped, inspect the
full length of the drivebelt for cracks and
separation of the belt plies. It will be necessary
to turn the engine (using a spanner or socket
and bar on the crankshaft pulley bolt) so that
the belt can be inspected thoroughly. Twist
the belt between the pulleys so that both
sides can be viewed. Also check for fraying,
and glazing which gives the belt a shiny
21.7b •.• then lock the tensioner by
inserting a drill bit (arrowed) through the
hole on the underside of the tensioner
appearance. Check the pulleys for nicks,
cracks, distortion and corrosion. If the belt
shows signs of wear or damage, it should be
renewed as a precaution against breakage in
service.
Renewal
4 If not already done, apply the handbrake,
then jack up the front of the vehicle and
support it on axle stands (see Jacking and
vehicle support). Remove the right-hand
front roadwheel and the wheel arch liner
cover for access to the right-hand side of
the engine.
5 For additional working clearance, remove
the air cleaner housing as described in
Chapter 48.
6 If the drivebelt is to be re-used, mark it to
indicate its normal running direction.
7 Using a spanner on the pulley centre bolt,
turn the tensioner against the spring tension.
Hold the tensioner in this position by inserting
a suitable locking pin or drill bit through the
special hole provided (see illustrations).
8 Slip the drivebelt from the pulleys.
9 Locate the new drivebelt on the pulleys in
the correct routing. If the drivebelt is being
re-used, make sure it is fitted the correct way
around.
10 Turn back the tensioner and remove the
locking pin/drill bit, then release it, making
sure that the drivebelt ribs locate correctly on
each of the pulley grooves.
11 Refit the air cleaner housing (if removed),
then refit the wheel arch liner and roadwheel,
and lower the vehicle to the ground.
23.4 Handbrake cable adjuster nut
(arrowed)
Refer to the procedures contained in
Chapter 2C.
1 With the vehicle on a slight slope, apply
the handbrake lever by up to 4 clicks of the
ratchet, and check that it holds the vehicle
stationary, then release the lever and check
that there is no resistance to movement of the
vehicle.
2 If necessary, adjust the handbrake as
follows.
3 Chock the front wheels then jack up the
rear of the vehicle and securely support it on
axle stands (see Jacking and vehicle support).
4 From inside the vehicle, lift out the rubber
mat from the base of the centre console. The
handbrake cable adjuster nut is accessible
through the access opening in the console
base (see illustration).
5
Move the handbrake lever to the fully
released position then, using a deep socket,
turn the cable adjuster nut anti-clockwise to
remove all tension from the cables.
6 Depress the footbrake five times, then fully
apply and release the handbrake lever five
times.
7 With the handbrake lever set on the second
notch of the ratchet mechanism, rotate the
adjuster nut clockwise until a reasonable
amount of force is required to turn each wheel.
Note: The force required should be equal for
each wheel.
8 Now pull the handbrake lever up to the third
notch of the ratchet mechanism and check
that both rear wheels are locked. Once this
is so, fully release the handbrake lever and
check that the wheels rotate freely. Check
the adjustment by applying the handbrake
fully whilst counting the clicks emitted from
the handbrake ratchet and, if necessary,
re-adjust.
9 On completion of adjustment, refit the
rubber mat to the centre console, then lower
,the vehicle to the ground.
1 Accurate adjustment of the headlight beam
is only possible using optical beam- setting
equipment, and this work should therefore
be carried out by a Vauxhall/Opel dealer or
service station with the necessary facilities.
