Which of the following tasks is not normally carried out as part of scheduled routine maintenance for a light vehicle?

• Checking the operation of the lights

• Checking the condition of the tyres

• 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
