Fault Finding

Spares and tool kit

Most vehicles are supplied only with

sufficient tools for wheel changing; the
Maintenance and minor repair tool kit detailed
in Tools and working facilities, with the
addition of a hammer, is probably sufficient
for those repairs that most motorists would
consider attempting at the roadside. In
addition a few items which can be fitted
without too much trouble in the event of a
breakdown should be carried. Experience and
available space will modify the list below, but
the following may save having to call on
professional assistance:

Spark plugs, clean and correctly gapped

HT lead and plug cap – long enough to
reach the plug furthest from the distributor

Distributor rotor, condenser and contact
breaker points (where applicable)

Drivebelt(s) — emergency type may
suffice

Spare fuses

Set of principal light bulbs

Tin of radiator sealer and hose bandage

Exhaust bandage

Roll of insulating tape

Length of soft iron wire

Length of electrical flex

Torch or inspection lamp (can double as
test lamp)

Battery jump leads

Tow-rope

Ignition waterproofing aerosol

Litre of engine oil

Sealed can of hydraulic fluid

Emergency windscreen

Wormdrive clips

Tube of filler paste

If spare fuel is carried, a can designed for

the purpose should be used to minimise risks
of leakage and collision damage. A first aid kit
and a warning triangle, whilst not at present
compulsory in the UK, are obviously sensible
items to carry in addition to the above. When
touring abroad it may be advisable to carry
additional spares which, even if you cannot fit
them yourself, could save having to wait while
parts are obtained. The items below may be
worth considering:

Clutch and throttle cables

Cylinder head gasket

Alternator brushes

Tyre valve core

One of the motoring organisations will be

able to advise on availability of fuel, etc, in
foreign countries.

A simple test lamp is useful for checking

electrical faults

Carrying a few spares may save you a long walk!
