5If equipped with an automatic transmission,
disconnect the cooler lines from the radiator
(see illustrations). Disconnect the cooling fan
switch connector (see illustration 4.15).
Place a drip pan to catch the fluid and cap the
fittings. Note:The transmission oil cooler lines
enter the radiator on the left, while the power
steering cooler lines attach on the right side of
the radiator. On 1993 and 1994 models, the
cooler fittings require a spring-lock coupling
tool, normally used on fuel lines or air
conditioning lines.
6Remove the four bolts from the radiator
cowl panel and take off the panel (see
illustration).
7Lift out the radiator. Be aware of dripping
fluids and the sharp fins. Take care not to
damage the radiator fins by contact with other
parts.
8With the radiator removed, it can be
inspected for leaks, damage and internal
blockage. If repairs are necessary, have a
radiator specialist or dealer service department
perform the work, as special techniques are
required. Check the rubber mounting pads on
the bottom of the radiator (see illustration). If
they’re cracked or damaged, get new ones
before refitting the radiator.
9Bugs and dirt can be cleaned from the
radiator with compressed air and a soft brush.
Don’t bend the cooling fins as this is done.
Warning: Wear eye protection.
Refitting
10Refitting is the reverse of the removal
procedure. Be sure the rubber mounts are in
place on the bottom of the radiator.
11After refitting, fill the cooling system with
the proper mixture of antifreeze and water.
Refer to Chapter 1 if necessary.
12Start the engine and check for leaks.
Allow the engine to reach normal operating
temperature, indicated by both radiator hoses
becoming hot. Recheck the coolant level and
add more if required.
13On automatic transmission equipped
models, check and add fluid as needed and
check the power steering fluid level as well.
Expansion tank and coolant
reservoir, removal and refitting
14The expansion tank is located at the top
of the left-hand side inner wing. With the
cooling system drained below the level of the
expansion tank, remove the hoses, the
coolant level probe and the two screws
mounting it to the body (see illustration).
15Wash out and inspect the reservoir for
cracks and chafing. Renew it if damaged.16If the low-coolant level light has been
showing on the instrument panel, even when
the coolant level is correct, disconnect the
sensor’s connector and test it with an
ohmmeter (see illustration). The sensor
should be renewed if the resistance at the
connections is over 150 ohms.
Caution: Using a long-necked funnel to
add coolant can damage the sensor, which
is just below the expansion tank filler neck.

will be necessary to apply pressure to the
master cylinder piston and, at the same time,
control flow from the brake line outlets, it is
recommended that the master cylinder be
mounted in a vice. Use caution not to clamp
the vice too tightly, or the master cylinder
body might crack.
10Insert threaded plugs into the brake line
outlet holes and snug them down so that
there will be no air leakage past them, but not
so tight that they cannot be easily loosened.
11Fill the reservoir with brake fluid of the
recommended type (see Recommended
lubricants and fluidsin Chapter 1).
12Remove one plug and push the piston
assembly into the master cylinder bore to
expel the air from the master cylinder. A large
Phillips screwdriver can be used to push on
the piston assembly.
13To prevent air from being drawn back into
the master cylinder, the plug must be
replaced and tightened before releasing the
pressure on the piston assembly.
14Repeat the procedure until only brake
fluid is expelled from the brake line outlet
hole. When only brake fluid is expelled, repeat
the procedure with the other outlet hole and
plug. Be sure to keep the master cylinder
reservoir filled with brake fluid to prevent the
introduction of air into the system.
15Since high pressure is not involved in the
bench bleeding procedure, an alternative to
the removal and renewal of the plugs witheach stroke of the piston assembly is
available. Before pushing in on the piston
assembly, remove the plug as described inStep 12. Before releasing the piston, however,
instead of replacing the plug, simply put your
finger tightly over the hole to keep air from

Tools and working facilitiesREF•7
Special tools
The tools in this list are those which are not
used regularly, are expensive to buy, or which
need to be used in accordance with their
manufacturers’ instructions. Unless relatively
difficult mechanical jobs are undertaken
frequently, it will not be economic to buy
many of these tools. Where this is the case,
you could consider clubbing together with
friends (or joining a motorists’ club) to make a
joint purchase, or borrowing the tools against
a deposit from a local garage or tool hire
specialist. It is worth noting that many of the
larger DIY superstores now carry a large
range of special tools for hire at modest rates.
The following list contains only those tools
and instruments freely available to the public,
and not those special tools produced by the
vehicle manufacturer specifically for its dealer
network. You will find occasional references
to these manufacturers’ special tools in the
text of this manual. Generally, an alternative
method of doing the job without the vehicle
manufacturers’ special tool is given. However,
sometimes there is no alternative to using
them. Where this is the case and the relevant
tool cannot be bought or borrowed, you will
have to entrust the work to a dealer.

Buying tools
Reputable motor accessory shops and
superstores often offer excellent quality tools
at discount prices, so it pays to shop around.
Remember, you don’t have to buy the most
expensive items on the shelf, but it is always
advisable to steer clear of the very cheap
tools. Beware of ‘bargains’ offered on market
stalls or at car boot sales. There are plenty of
good tools around at reasonable prices, but
always aim to purchase items which meet the
relevant national safety standards. If in doubt,
ask the proprietor or manager of the shop for
advice before making a purchase.
Care and maintenance of tools
Having purchased a reasonable tool kit, it is
necessary to keep the tools in a clean and
serviceable condition. After use, always wipe
off any dirt, grease and metal particles using a
clean, dry cloth, before putting the tools away.
Never leave them lying around after they have
been used. A simple tool rack on the garage
or workshop wall for items such as
screwdrivers and pliers is a good idea. Store
all normal spanners and sockets in a metal
box. Any measuring instruments, gauges,
meters, etc, must be carefully stored where
they cannot be damaged or become rusty.
Take a little care when tools are used.
Hammer heads inevitably become marked,
and screwdrivers lose the keen edge on their
blades from time to time. A little timely
attention with emery cloth or a file will soon
restore items like this to a good finish.
Working facilities
Not to be forgotten when discussing tools
is the workshop itself. If anything more than
routine maintenance is to be carried out, a
suitable working area becomes essential.
It is appreciated that many an owner-
mechanic is forced by circumstances to
remove an engine or similar item without the
benefit of a garage or workshop. Having done
this, any repairs should always be done under
the cover of a roof.
Wherever possible, any dismantling should
be done on a clean, flat workbench or table at
a suitable working height.
Any workbench needs a vice; one with a jaw
opening of 100 mm is suitable for most jobs.
As mentioned previously, some clean dry
storage space is also required for tools, as well
as for any lubricants, cleaning fluids, touch-up
paints etc, which become necessary.
Another item which may be required, and
which has a much more general usage, is an
electric drill with a chuck capacity of at least 8
mm. This, together with a good range of twist
drills, is virtually essential for fitting
accessories.
Last, but not least, always keep a supply of
old newspapers and clean, lint-free rags
available, and try to keep any working area as
clean as possible.
