Before you start
  • Please dont attempt this job without the
    cam/crank locking tool. The proper tool is a
    really tight precision fit.
  • There are no key-ways on the crank or cam pulleys
    so unless the crank / cams are locked the timing
    will be lost.

1. Unclip plastic cover and remove rubber
seal2. Unscrew and remove wiper arms

1. Remove wheel and wheelarch liner. 2. Jack
car up as shown. Note use of trolly jack under
sump to support engine. Use wood block.(Not
shown Remove the fan belt 15mm socket on long
bar and pull down on tensioner.)
7
1. Remove throttle butterfly (4 bolts and 1
connector). This is on a rubber seal behind. When
refitting put a light smear of RTV sealent to
ensure a good seal.2. Then remove 2 rubber core
plugs on the end of each cam. 1 is hidden behind
throttle butterfly. Punch a screwdriver through
the middle and prise out. Dont try and put the
cam lock tool in yet as its a very tight fit so
you need to lock the crank first.

1. Looking from the top of the dipstick down the
front of the engine use a couple of tie-straps to
lift the water hose up and out the way.2. Follow
the dipstick down to where it goes into the
block. Just to the right is a bolt (See next
slide). Undo the bolt 3. Insert the crank pin.
Turn the crank until the pin fully locates. This
is TDC on No1.

1. Crank pin bolt in more detail. Youll need
an E16 socket. Its tight and a pain to get to.

1. Back to the cams now. The cam lock tool
should now slide into the slots at the end of the
cams. Its a very tight fit.2. The locking pin
for the tool slots into a notch on the head.

1. Remove the cam belt cover. This this one of
the easiest Ive come across to remove. Top half
is alumnium and held with some 10mm bolts, lower
part is plastic with 3 x 6mm bolts. All are easy
to access if you jack the engine up and down to
utilise the gaps in the inner wing.
12
1. 12mm allen key to remove the cap on the end
of the dephaser. There will be some loss of
oil.Note that there is a copper washer behind
this cap. Leave the cambelt on for now to give
extra support to holding the cams in place.

1. Now you can remove the main bolt. The pulley
just pulls off. No keyway

1. Losen cam belt tensioner and remove cambelt

To replace the belt, put the dephaser back on
but leave it loose and free to rotate. Put the
cambelt back on but keep the tension on the right
hand side. When the belts back on you can torque
to pulley bolt. I put mine on to 90lb, and
because I used the correct locking tools
everything stays lined up.Putting everything
back is simply the reverse process.
