Changing the engine oil and filter
Checking the steering geometry
Before checking the exhaust emissions of an engine you should:
check and adjust the tension of the alternator drive belt
ensure the engine is operating in normal ambient temperatures
ensure that the engine oil and filter have been changed
run the engine until it reaches normal operating temperature
A vehicle protection kit consists of:
a seat cover, floor mat and overalls
a floor mat, steering wheel cover and gloves
a seat cover, floor mat and steering wheel cover
a steering wheel cover, floor mat and handbrake cover
A tyre is outside legal limits if it has:
a cut more than 25mm or 10% of the section width which exposes the casing cords
a cut of more than 1.6mm in depth anywhere on the tyre tread or the tyre casing
any part of the tread less than 0.16mm in depth measured around the tyre circumference
any part of the tread less than 0.16mm in depth measured across the tread width
The function of the one-way clutch that is fitted to a pre-engaged starter motor is:
to prevent the engine driving the starter motor if the starter switch is not released
to prevent damage to the flywheel ring gear during the engagement of the pinion
to limit the torque that is transmitted by the starter motor during engagement
to allow slight rotation of the pinion in the event of tooth to tooth abutment
In a drum brake assembly the hydraulic wheel cylinder applies the leading brake shoe:
in the same direction as the brake drum is rotating
in the opposite direction to the rotation of the brake drum
against the brake disc to prevent brake fade occurring
to reduce the self-servo effect caused by the brake drum
What does the term Hygroscopic mean?
Absorbs air from the atmosphere
Corrosive to metal
Absorbs water from the atmosphere
Boils easy
In an engine lubrication system the relief valve:
controls the viscosity index of the engine oil
limits the minimum oil pressure to the bearings
limits the maximum oil pressure to the bearings
allows oil to the bearings if the filter is blocked
The legal minimum tyre tread depth for passenger cars and trailers up to 3500kg GVW is:
0.16mm for 75% of the tread width for the complete circumference of the tyre
1mm for 75% of the tread width for the complete circumference of the tyre
1.6mm for 75% of the tread width for the complete circumference of the tyre
16mm for 75% of the tread width for the complete circumference of the tyre
A four cylinder four-stroke in-line engine has a firing order of 1342. When cylinder 1 is on the compression stroke:
cylinder 4 is on the induction stroke
cylinder 2 is on the power stroke
cylinder 3 is on the power stroke
cylinder 2 is on the exhaust stroke
The sidewall marking of a tyre is 195/65R15. This means that the:
tyre is fitted to a 195mm diameter wheel
diameter of the tyre is 15 inches
tyre is a cross-ply construction design
height of the tyre is 65% of the width
In a direct injection compression ignition engine the injector:
injects the fuel into an ante-chamber
injects the fuel into the manifold
is a single hole pintle type design
injects the fuel into the cylinder
Dual line hydraulic brake systems are used because they:
incorporate self adjusters
are easy to bleed
maintain braking if one line fails
are easy to maintain
In the diagram what is component 1
Piston
Caliper
Disc
Pads
A transistor is an electronic component that:
is fitted to alternators to rectify AC to DC
is fitted to the exhaust system to sense oxygen
conducts electricity in one direction only
has three connections; base, emitter & collector
