8Tighten the alternator mounting and
adjustment nuts and bolts in the order shown
(see illustration).
9Where applicable, refit and tension the air
conditioning compressor drivebelt.
10Reconnect the battery negative lead.
11Drivebelt tension should be rechecked
and if necessary adjusted after the engine has
been run for a minimum of ten minutes.
DOHC models
12Three different types of drivebelt
arrangement are used, depending on model
(see illustrations).On models without powersteering, the drivebelt is tensioned by moving
the alternator. On models with power steering,
the power steering pump is also driven by the
coolant pump/alternator drivebelt and an
automatic belt tensioner is fitted (see
illustration).On models with air conditioning,
the drivebelt drives the alternator, coolant
pump, power steering pump and air
conditioning compressor, and an automatic
belt tensioner is fitted.
13On models without power steering, loosen
the alternator mounting and adjustment bolts,
and pivot the alternator towards the cylinder
block. Slip the drivebelt from the pulleys.
14On models with power steering, the
automatic tensioner can be released using a
17 mm socket and a wrench on the boss in
the centre of the pulley. Lever the tensioner
assembly clockwise, slide the belt from the
pulleys, then slowly release the tensioner.
15To fit a new belt on models without
power steering, slide the belt over the pulleys,
then lever the alternator away from the
cylinder block until the correct belt tension is
achieved. Lever the alternator using a plastic
or wooden lever at the pulley end to prevent
damage. It is helpful to partially tighten the
adjustment link bolt before tensioning the
drivebelt. When the correct tension is
achieved, tighten all the bolts.
16To fit a new belt on models with power
steering, lever the tensioner clockwise as
during removal, then slide the belt over the
pulleys, and slowly release the tensioner.
1The battery fitted as original equipment is
“maintenance-free”, and requires nomaintenance apart from having the case kept
clean, and the terminals clean and tight.
2To clean the battery terminals disconnect
them, after having first removed the cover
(later models) - negative earth first. Use a wire
brush or abrasive paper to clean the
terminals. Bad corrosion should be treated
with a solution of bicarbonate of soda, applied
with an old toothbrush. Do not let this solution
get inside the battery.
3Coat the battery terminals with petroleum
jelly or a proprietary anti-corrosive compound
before reconnecting them. Reconnect and
tighten the positive (live) lead first, followed by
the negative (earth) lead. Do not overtighten.
4Keep the top of the battery clean and dry.
Inspect the battery tray for corrosion, and
make good as necessary.
SOHC engines
1The valve clearances must be checked with
the engine cold. On carburettor models
remove the air cleaner.
2Disconnect the HT leads from the spark
plugs and release them from the clips on the
camshaft cover.
3On fuel injection models, unbolt and
remove the bracing strut securing the inlet
manifold to the right-hand side of the cylinder
head.
4Where applicable, unclip any hoses and
wires from the camshaft cover, then unscrew
the securing bolts and remove the camshaft
cover and gaskets. Take care not to lose the
spacer plates which fit under the bolt heads,
where applicable.

Caution: Before carrying out
any work on the vehicle battery,
read through the precautions
given in “Safety first!” at the
beginning of this manual.
It will be easier to turn the
engine by hand if the spark
plugs are removed but take
care not to allow dirt to enter
the spark plug holes.
